Sealing the cracks in the basement floor can drastically reduce the amount of radon that enters a property through these openings. But it is quite unlikely that merely repairing the cracks will be sufficient to reduce such numbers over the long run. Cracks should be sealed, and thick, non-porous epoxy coatings should be applied for optimal results (with a dry film thickness of over 10 mils).
However, the effectiveness of acrylic as well as other soak-in sealers as radon mitigation techniques has not been verified by scientific research (by the EPA or CDC). Some authorities have issued warnings to customers about the risks associated with using them. Fixing the Roof Roofing Systems provides leaf guard installation and maintenance in the Melbourne area. Leaf guard, leaf screens, and leaf filters mesh are all names for the same types of products. But the EPA, the Radon Awareness association, and even radon mitigation companies all agree that basement coatings are most effective when used in tandem with a sub-slab depressurisation device. This method eliminates radon's ability to enter a house by sucking it up from the foundation and releasing it into the open air, where it is diluted to an unsafe level.
If you know anything about radon, then you know that the gas may seep into a house through crevices in the foundation. This fact explains why we get a lot of inquiries about whether or not sealing off basement floors can mitigate the effects of radon.
A lot of people wonder this since they aren't sure if they have a radon problem at home. They wish to get a jump on things before it actually takes place. We recommend first that you have your home tested for radon to see whether it contains levels that could be harmful to your family.
The installation of a radon mitigation system from a dependable company, such as Radon Eliminator, is essential if radon levels in your house are high. However, does protecting your basement floor with epoxy help in the battle against excessive radon gas levels?
Read on to learn how epoxy coatings and other floor sealing technologies can reduce the amount of radon that enters a home through the floorboards. The unpleasant truth is that we can only say "maybe" in response to this enquiry.
It bears repeating that the only method to ensure that radon will be removed from your home is to instal a mitigation system. Although closing the cracks in the basement floor may help, it is not likely that this will considerably reduce the radon levels in your home.
Sealing all of the cracks and applying thick, non-porous epoxy coatings all over the surface would be a more efficient method. While soak-in sealers like acrylic and others are touted as radon mitigation methods, it's crucial to remember that these solutions have not been tested.
Some governments have gone as far as to issue explicit safety warnings to consumers. The EPA suggests installing a sub-slab depressurisation system in tandem with basement coatings.
Sub-slab depressurisation systems remove radon from underneath a building and release it into the surrounding environment using fans. Radon is removed by having air flow upward through the sub-slab. As soon as it hits air, its concentration decreases below the level at which it may cause harm.
The Answer to Your Musty Cellar
When it comes to protecting and preserving concrete and concrete blocks in commercial and residential settings, no product compares to RadonSeal Deep-Penetrating Concrete Sealer, which has been on the market since the late 1990s.
RadonSeal is a reactive, clear, aqueous sealant used for strengthening and waterproofing cementitious building materials such heavyweight concrete blocks, poured concrete, grout, limestone, and more.
Sealing the pores and capillaries of concrete using RadonSeal helps to damp-proof concrete, reduce basement moisture, soil gas infiltration, and radon gas levels. Consequently, this makes the concrete less permeable to liquid water and vapour. Concrete is strengthened and hardened while being protected from freeze-thaw, dusting, deicing chemicals, cracking, efflorescence. Indoors and out, you can count on it.
Unlike most store-bought concrete sealers and clear coatings whose primary purpose is to improve the surface's appearance, RadonSeal is not a membrane or clear coating sealant but rather a penetrating sealant.
Infiltration by RadonSeal. It's working its way down into the concrete, sealing off any little cracks or crevices beneath the surface. RadonSeal will not alter the look of a concrete floor in any way. It won't leave behind a glossy film and won't change the concrete's surface friction.
RadonSeal is the best concrete sealer to use before applying concrete levellers, clear sealants, concrete paint, floating slabs, epoxy floor coatings, glue and wood floors due to its vital and distinctive features. The seal's inherent anti-slip properties make it a great choice for high-traffic areas such as outdoor concrete, driveways, concrete steps and ramps, parking lots, and the like.
Concrete Sealer That Lasts Forever
Since porous concrete allows the RadonSeal concrete sealer to penetrate deeply into the material (up to 4 inches), it can then chemically react with free lime and alkali. This keeps water from seeping into the concrete and wreaking havoc on the structure (Portland Cement). RadonSeal begins to cure and harden as a silicate mineral during the course of its continuous reaction. Because of this, it expands to completely seal any cracks in the concrete.
The seal will remain intact and invulnerable to wear and tear forever. To no avail, water pressure given to the unfavourable side of the concrete will result in its removal. The sealant ends up being an integral part of the concrete. No additional applications are ever required. The effect is the same as if you had poured more concrete.
Concrete that resists water
When applied, RadonSeal helps prevent groundwater seepage, damp concrete blocks, dampness, damp concrete, and sweating garage floors in below-grade concrete, subterranean concrete, slab-on-grade construction, basements, cellars. If your garage floor sweats, use RadonSeal to prevent damage.
They are used to seal the exterior foundation walls before damp-proofing membranes are installed (tar, rubberised coatings, asphalt). In the event that membranes break, coatings fail, wear away. RadonSeal will help waterproof the concrete matrix. As a result, efflorescence and salt deposits will be less likely to dissolve, as capillary water seepage and vapour escape will be reduced.
Increases Concrete Strength
RadonSeal will not only waterproof the concrete, but it will also strengthen and densify it. By fortifying the concrete against surface faults including spalling, dusting, crazing, cracking, aggregate pop-outs, and more, the integrity of the substrate can be better preserved.
Protecting outdoor concrete from freeze-thaw cycles, acid rain, automotive traffic, de-icing chemicals, lawn irrigation systems, reinforcing bar corrosion, and unsightly efflorescence is made possible with RadonSeal, a concrete densifier.
Why You Should Use RadonSeal On Your Concrete?
Avoiding the use of a concrete sealer is similar to the common practise of not protecting or sealing wood. Whether it is installed indoors or outdoors, RadonSeal provides numerous benefits to the concrete, the homeowner's home, and the basement.
- Waterproofing concrete can greatly reduce the amount of water vapour, moisture, and water seepage into the concrete by capillary action.
- RadonSeal's reaction with the alkalis in the concrete makes it effective against efflorescence and other salt deposits.
- zero VOCs, zero irritating odours, zero solvents, and zero fumes; environmentally friendly. Designed for use in domestic settings!
- Simple to implement and h2o-based (not solvent-based). Apply with a hand-pumped, low-pressure "garden or insect" sprayer.
- To prevent water vapour from penetrating the subfloor and causing damage to moisture-sensitive flooring, use a vapour barrier.
- If you want to assist reduce radon levels, one thing you may do is have concrete poured with tighter pores and fewer capillaries.
- A breathable sealant is one that doesn't prevent moisture vapour from escaping. Makes it possible for concrete to dry out and breathe.
- Remediating mould is a technique used to lessen the likelihood of further mildew and mould growth.
- Removes musty odours from a damp basement by lowering humidity levels.
- Helps prevent cracks caused by rebar's corrosion and expansion. This lessens the potential for cracking.
- By adding concrete hardener, the surface becomes more flint-like and durable. Protects from road salts and frigid temperatures.
- The process of deep cleaning exposes unsightly contaminants such as old efflorescence, trace amounts of oil and grease, and even animal urine. This procedure eliminates them from the water supply.
Methods of Utilizing Concrete Countertops
Because of how RadonSeal works, high-quality concrete with at least three inches of thickness and features like these will yield the best results.
- Poured concrete sealer is an ideal choice for protecting below-grade damp basement walls, foundation walls, and basement floors. Concrete floors for garages. Buildings with a slab on the ground. Construction slabs for the subfloor. Surfaces laid down in industrial settings. Manufacturing concrete; concrete used in business. Examples of concrete structures include driveways, pool decks, walkways, patios, concrete curbs, cooling towers, parking lots, carports, seawalls, bridges, storage tanks, columns, and building facades.
- Concrete block sealer is useful for protecting the walls of a basement, the exterior of a building, or a retaining wall.
- Mortar sealer is used to keep the mortar between concrete blocks and porous mortar in ancient stone foundation walls from drying out and cracking.
- An old basement with limestone and concrete walls that have been sealed. Limestone is frequently used for building exteriors and columns. Exterior or interior, whichever you like.
- As a protective coating for indoor concrete, stucco is often used as a sealant.
Sealant For Foundation Walls And Floors In The Basement
Used indoors, the RadonSeal Concrete Sealer protects against water damage caused by humidity, water vapour, capillary water seepage, and efflorescence on below-grade foundation walls, retaining walls, slab-on-grade construction, sweating garage slabs, basement floors, foundation concrete blocks walls. Other uses include retaining slab-on-grade construction, walls, foundation concrete block walls. RadonSeal is not only effective for preventing water seepage, but may also be used to strengthen and compact concrete, whether it is located inside or outside. Protecting the concrete against dusting, cracking, efflorescence, and spalling while also contributing to its preservation.
When compared to other chemical concrete sealers, RadonSeal Plus and RadonSeal Standard are the most effective because they are the most powerfully engineered silicate-based concrete sealers, penetrating deeper, carrying more active minerals into the concrete, and sealing tighter. In contrast to drilling, piercing doesn't require the assistance of gravity, hence it can be used on heavy surfaces like basement ceilings and walls. Capillary action is responsible for the penetrating effect.
Instead of excavating the basement or foundation, RadonSeal is often sprayed on the inside of the walls. This is because it is not always practical or affordable to excavate foundation walls. However, if it can be applied to both sides of the concrete walls, it also protects the waterproofing coating from the alkalis in the concrete, increasing its lifespan, and preserving the outside surface of the concrete. It also has the benefit of protecting the outside surface of the concrete, if it can be applied to both sides of the walls.
Sealing for Radon Must Be Done Before Wood Floors Or Paint
RadonSeal can be used to create a paintable surface on concrete as long as the surface has adequate pores (does not bead water). You need to find Melbourne roofers, right? A Roofing System for Roof Repair is available to help you out.
If your basement walls or concrete floors have excessive levels of moisture, you should seal them before installing any kind of paint, floor coating, mastic, glue, gloss finish epoxy or wet-look sealer, urethane coating, surface leveller, concrete overlay, or moisture-sensitive flooring. All sorts of floor paints, varnishes, and adhesives won't stick to the floor because of this (wood floors).
It is recommended to apply RadonSeal, a penetrating sealant, on concrete flooring. With this sealer in place, the concrete's pores and capillaries will be impenetrable to liquid water and water vapour. Deeply sealed concrete slabs are better at preventing efflorescence, which prevents epoxy coatings and paints from breaking and flaking.
Radonseal is useful for preventing the buckling and mould growth of hardwood floors and the delamination and blushing of transparent coverings.
Abatement of Radon Gas
Employing a contractor who has finished and been certified by a Radon Proficiency Program is your best bet when attempting to lower radon levels in your house. Here you'll find a directory of radon-reduction firms that have been verified as legitimate by the National Radon Safety Board or the National Environmental Health Association.
The vast bulk of radon is likely to come from the soil underneath houses, thus it is important to seal those areas off. Radon levels can be as high as 1,000 pCi/L or more in the soil beneath the basement flooring of many homes. Any cracks or holes leading to the outside dirt should be sealed with gas-tight materials on the basement floor and walls. Rather of silicone, polyurethane is the prefered adhesive for usage with concrete.
However, research has shown that only around 20% of households may achieve a reduction in radon levels of more than 50% by sealing gaps and cracks in their basements. It's worth a shot, despite the fact that it may not have much of an effect, because it's cheap and it's part of the next approach. Sealing is more likely to have a noticeable effect when applied to bigger regions or when more cracks and gaps are sealed. Very little cracks are not worth the effort to seal.
Soil depressurisation is effective in reducing radon levels to below 2 pCi/L in the vast majority of situations. The air is sucked in from the basement's lower levels and discharged to the roof's upper levels. A fan inside a three- or four-inch-wide pipe continuously draws air from the residence and expels it. This keeps the air outside the home and stops it from being trapped inside.
To prevent radon gas from seeping into the basement, this method reduces the air pressure below the floor, allowing air to escape through cracks and crevices in the foundation. Radon Reduction: Sub-Slab Depressurisation, an eleven-minute videotape, is available in every public library.
Installing a system by a licensed professional might cost anywhere from $800 to $2,000, with an average cost of roughly $1,200. If you don't have a lot of experience working as a contractor, depressurizing a sub-slab is not a job you should attempt on your own.
The Five Best Ways To Decrease Radon
Testing the home for radon levels is crucial. It's a radioactive gas with no discernible smell or colour, and prolonged exposure to high concentrations can be fatal. The EPA and the WHO, together with ourselves, advocate for testing. The question is, "Now what?" Taking daily readings is necessary since radon levels are continually shifting.
At Roof Repair Roofing Systems, we've compiled a list of our top five easy recommendations for lowering indoor radon levels. Advantages of long-term radon detectors include the ability to verify that radon levels have been reduced to an acceptable level and to continue monitoring radon levels over time.
- If you want to make sure air is circulating freely throughout your entire house, try experimenting with different venting setups.
- There are a few low-cost methods for sealing around doors and other openings in a structure, including draught excluders and rubber seals. This will seal the building up so no air can go in or out. With the right intentions, this method could be useful for reducing the amount of radon in subterranean spaces like basements. Visiting your local hardware store to ask about recommended sealants is a good idea.
- You should use materials made specifically for caulking to seal entry points in your floors and walls.
- Homes with a ground floor that is raised from the ground often have vents installed in the subfloor. These houses also feature storage areas below ground level. They frequently become clogged with dirt or foliage; clearing the obstruction will increase airflow.
- Know that some of them have been sealed off on purpose to cut down on draughts, and consult an expert if you have any questions.
- Since radon usually enters buildings through cracks, these should be sealed. Sealing large cracks and gaps in the structure can help lower radon levels and improve energy efficiency. It can still enter through smaller apertures as a gas, but large entry points are ineffective, as is the case with everything else. In addition, there is a sizable pool of professionals ready to guide you through this process.
A Word Of Caution About Basement Finishing And Radon
Improvements to the basement are a great idea for two reasons: making the space more usable and adding to the home's value. But before you begin, take the necessary steps to provide a safe and healthy environment for you and your loved ones.
The odourless and tasteless gas radon is produced by the breakdown of uranium in rocks and soil. Even though it's present naturally in the earth and perhaps in a lot of people's houses, it becomes an issue when concentrations are too high.
A common way for radon to infiltrate a home is through cracks in the basement's concrete. There are a number of potential causes for these cracks to emerge, including the concrete's own expansion and contraction as it cures, the weight of nearby trees, poor drainage, and seasonal soil temperature swings. Roofing issues? Need Melbourne-area maintenance or repairs? In this case, Roof Repair Roofing Systems is the company to call.
You can move on to putting in the subfloor after you've completed this mandatory step. Before installing your finished flooring, you should instal a subfloor system like DRICORE, which will prevent mould and mildew from growing in your basement and insulate against the chilly concrete with its raised air gap design. Doing so before installing finished flooring can help prevent the growth of mould and mildew in the basement. Warmer and less stressful on the feet, these floors are the result.
Now that you have a solid base, you can start working on the basement's finishing touches, including the flooring and walls. Following that, you can move on to the more fun parts, like picking out the completed flooring and lighting fixtures, safe in the knowing that you are creating a space that is not only aesthetically beautiful but also safer for your loved ones.
The amount of radon entering a home can be greatly reduced by sealing cracks in the basement floor. When utilised in conjunction with a sub-slab depressurisation system, epoxy coatings excel in protecting against hydrostatic pressure. By vacuuming it up from the ground, this technique prevents radon from entering a home. Installing a mitigation system is the only surefire way to get rid of radon in your house. The Environmental Protection Agency (EPA) recommends a sub-slab depressurisation system be installed in addition to basement coverings.
As early as the late '90s, people could buy RadonSeal Deep-Penetrating Concrete Sealer. In order to get the greatest results from concrete levellers, transparent sealants, concrete paint, floating slabs, epoxy floor coatings, glue, and wood flooring, RanonSeal is the best concrete sealer to use first. Since the seal has natural slip resistance, it is an excellent material for heavily travelled regions. Water vapour, moisture, and water seepage into the concrete via capillary action can be considerably reduced if a concrete sealer is not used. By reacting with the alkalis in the concrete, RadonSeal is able to prevent efflorescence and other salt deposits.
Stucco is commonly employed as a sealer for concrete floors within buildings. Both the facade and the columns of a structure can benefit from the durability of limestone. If the concrete surface has sufficient porosity, RadonSeal can be utilised to create a paintable surface (does not bead water). Hardwood floors treated with radonseal will last longer without warping or becoming a breeding ground for mould. The dirt beneath the basement flooring of many homes can have radon concentrations of 1,000 pCi/L or higher.
The best option is to hire a professional that has completed and been certified by a Radon Proficiency Program. In most cases, radon levels can be lowered to below 2 pCi/L with the use of soil depressurisation. The radioactive gas radon has no taste, no smell, and no visible colour. The best way to keep tabs on radon levels is using a long-term detector. When uranium in rocks or soil decays, radon is released into the environment.
In many cases, radon enters a house through crevices in the basement's concrete. Lowering radon levels and increasing energy efficiency can be accomplished by sealing significant cracks and holes in the structure.
- The amount of radon entering a home through basement floor gaps can be greatly reduced by sealing the crevices.
- For the best results, cracks should be sealed, and thick, non-porous epoxy coatings should be used (with a dry film thickness of over 10 mils).

Frequently Asked Questions About Basement
No, buying a dehumidifier will not make radon go away. Research conducted by the Environmental Protection Agency (EPA) has disproved this idea.
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
"Radon gas is approximately 7.5 times heavier than air,” according to the Environmental Protection Agency (EPA). So it will naturally collect near the lowest level of a home if the air remains undisturbed.
Radon, soil gasses, and water vapour will easily pass through openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.
As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.
