    If you seal off the basement's exterior wall, you can stop water from seeping in through the foundation. This aids in the prevention of flooding. The required work here is both different in theory and practise from that of internal waterproofing. In contrast to interior waterproofing, which allows water to seep into the basement before managing it away, this method of water management is designed to assist prevent water from ever entering the basement. This strategy for water control also aids in avoiding the occurrence of basement flooding.

    Waterproofing a basement from the outside is a highly effective and flexible method that can be used on either poured masonry blocks or concrete basement walls. The exterior of a basement must be waterproofed by excavating the soil around the walls, installing a moisture barrier, and then installing dimple board, which is shaped to deflect water away from the wall.

    Because it prevents leaks before they even get inside, this method is favoured by people who do not want to have any work done on the inside of their home. When it comes to exterior basement waterproofing, the Olshan system uses a drainage system that includes a footer drain set in gravel. The gravel fill mitigates hydrostatic pressure, and the footer drain aids in the removal of water from the foundation.

    • Water from the basement's exterior walls will be channelled into a drainage system thanks to the dimple board and exterior moisture barrier that will be installed.
    • The moisture membrane shields from both seepage and the groundwater outside.
    • In order to alleviate hydrostatic pressure and allow water to flow into the footer drainage system, the dirt is removed and washed gravel measuring 3/4 inches is used in its place.
    • Water can be safely diverted away from the house's foundation thanks to the footer drain, which is attached to the exterior of the building.
    • A sump pump can be installed, and depending on the situation, either a secondary pump can be used to boost the primary pump's output, or gravity can be used to flush the system.

    Things To Keep In Mind

    • It's a great choice for homeowners with finished basements because the work can be done outside without disturbing the space inside.
    • Though they are commonly advised, sump pumps may not always be necessary.
    • It takes a lot more time to instal than standard interior waterproofing.
    • Product servicing is an option.
    • Waterproofing the outside walls, with a drainage systems, vapour barrier, dimple board.

    After the water problems are fixed, these features not only help reduce the damp air inside the home, but they also aid in minimising the property's water damage. The positive effects of exterior waterproofing on air quality may be amplified by the installation of an optional air quality system. Are you interested in house renovations in Melbourne?

    Exterior Basement Waterproofing

    what causes basement flooding

    We realise that addressing water intrusion can be a difficult and time-consuming task for homeowners. After you have cleared the area, mopped up the water, cleaned the floor and walls, and dried out the basement, you can get back to work. There is no substitute for a high-quality, in-wall water drainage system. And if water is entering your basement, this is the answer you need. Yet you need not feel completely helpless; there are measures you can take to cut down on the amount of water that makes its way inside.

    The family-owned and -operated business Acculevel has been serving the residential properties of and the surrounding areas with waterproofing services since 1996. We stock a wide variety of water drainage systems; the one you need will be determined by the make-up of your foundation. These waterproofing systems have a lifetime warranty, can quickly and efficiently manage any water that may enter the property, and are a sound investment overall. Acculevel's goal with its customer service is to provide a flawless experience from start to finish, earning a perfect score in every category. However, before requesting our help, we will explain three ways in which you can lessen the amount of water that makes its way inside your house.

    Downspouts and gutters

    Let's start with the task that calls for a ladder, shall we? You'll have to ascend a ladder if you want to check the gutters on your home. Clear the area of any obstructions, such as pine needles, leaves, or other debris that could be preventing water from passing through. Make the necessary repairs or replace any broken components.

    The main reason for installing gutters is to collect and divert water from roofs and foundations. By channelling water away from your home's foundation, gutters keep rain from pooling at the eaves. The downspouts that are attached to the very end of the guttering and act as an outlet for rainwater are similarly important.

    It is recommended that your home's downspouts extend out and away from the building by at least ten feet. It's possible that hydrostatic pressure and water seepage from nearby water sources will put stress on your foundation.

    Decorations for the Outdoor

    The landscaping adjacent to the house's foundation is the next priority. What if you had any landscaping features, such as flower beds or bushes, near your home. If that's the case, you should make sure there's enough drainage. Birdbaths, large boulders, and other potential water catchbasins should be checked to ensure they are not drawing water towards the house.

    The foundation's surrounding area, including any borders you may have constructed, should be checked for water accumulation. Timbers that mimic railway ties are highly sought after due to their charming, old-world charm. However, termites and other pests love to feast on wet wood, so that presents a challenge. A concrete foundation is impervious to damage from termites, but the wooden subflooring and joists can be eaten away by these pests (beams, joists, etc.).

    In the same vein, it's recommended that you keep any large trees or shrubs at least a few metres away from your home. The quantity of water necessary for these plants is one possible explanation for this. Nonetheless, remember that the same roots that are excavating the soil may be doing the same thing to your building's structure.


    Before making major changes to the landscaping in your yard, you should check the slope of your yard. Stand in a well-lit area where you won't be tempted to wander off, like your driveway or the sidewalk, and yet where you can still get a good look at your property's layout. The land around your home should have a gentle downward slope away from the building, rather than be completely level. Natural water drainage is helped along by this measure.

    You will be held accountable for repairing the slope if it has been harmed. Depending on the situation, this may require replacing the soil or moving the plants. A professional landscaping service can do this for you, and they can also help you decide which plants are best for your yard and where they should go.

    For What Reasons Should An Outside Basement Be Waterproofed?

    Cracks and other porous areas in the basement wall can allow water from the soil around the basement to seep inside, making the basement damp. Concrete walls can develop weak spots that let water seep through if problems arise during the pouring process, and masonry block walls can develop cracks at the mortar joints.

    The amount of water that seeps into your basement is largely dependent on the soil's composition. The amount of growth caused by soil absorbing moisture and swelling varies greatly from soil type to soil type. A large portion of the soil in Milwaukee and its suburbs is clay. There is a lot of talk about how clay soil can hold onto water, how much it can expand, and how poorly it drains. As the area around the foundation swells and expands, pressure builds up, and eventually, even a small crack or crevice will become large enough to let water in.

    All of these issues can be resolved by waterproofing the basement's exterior. The first step is to dig a trench away from the basement's exterior wall. Next, a moisture barrier is installed, the trench is backfilled with gravel, and a footer draining system is built. It's unclear how important a sump pump actually is. There are numerous moisture barriers available, and some wall preparation may be necessary before installing one. Accurate Basement has the trained experts who can advise you on the best moisture barrier for your basement. Due to the nature of the soil here, gravel fill is an essential ingredient.

    Having the exterior of your basement sealed has many advantages. As opposed to dealing with water that has already made its way into your basement, this system works to prevent further seepage. It directs runoff away from your house's base and into the municipal sewer system. Hydrostatic pressure is reduced by the gravel, preventing it from building up.

    The primary advantage is that it makes your damp basement habitable. With a properly installed exterior basement waterproofing system, not only will your basement be free of seepage and damp spots, but also the musty smells that come with them. As a result of these enhancements, the value of your property will rise.

    • Water supply being cut off at the source.
    • It lessens the possibility that water seepage into your foundation will cause structural damage over a long period of time.
    • Because of the lower humidity in your basement, you'll spend less money cooling and dehumidifying it.
    • In contrast to other solutions, this one will last.

    Techniques For Waterproofing The Outside

    • It is necessary to excavate all the way around the building's outside to ensure proper waterproofing. The typical depth and width of an excavation is 5-9 feet and 1 to 2 ½ feet, respectively. The depth of the excavation is going to be based on how high up your land is. ​
    • In order to protect workers and keep the excavation site from being backfilled, speed shoring is installed.
    • After excavating, remove the old weeping tile. After this is finished, we can start laying the foundation. Next, a layer of filter cloth 4 inches thick is laid down beneath a new weeping tile.
    • Cleaning and Inspecting the Foundation Walls The next step is to remove any debris and inspect the foundation walls for cracks or other damage. The broken pieces are chiselled away, and then the cracks are filled and sealed with a special cement that doesn't shrink.
    • To instal a rubber membrane using a trowel, do as follows: When preparing to waterproof the exterior of your foundation, this is a crucial step. In the event of further settlement and movement of the foundation, it is designed to lengthen and grow.
    • A layer of rubberized waterproofing is applied, and then a layer of mesh is installed on top of the membrane. This serves as both an additional layer of rubber and a reinforcement for the membrane's primary layer.
    • The termination bar pinnacle holds the soil-side drainage sheet: Commercial drainage serves as both a protective drainage and board membrane (much better than residential grade dimple board).
    • The installation of a window well is necessary if any of your home's windows are below ground level. From the bottom of the window well to the foundation of the building, a four-inch-deep weeping tile is laid vertically. To prevent backups, keep the weeping tile and pipe from coming into contact with one another.
    • A layer of clear gravel three quarters of an inch thick is spread over the weeping tile to improve water flow. Since too much water in the soil could cause the weeping tile to become clogged or obstructed, a layer of gravel is typically incorporated into the soil before installation.
    • The hole is filled with native dirt that is subsequently compressed to its original density. Once the dirt is back where it belongs, you can rest easy knowing that water won't be able to seep in through the foundation again.

    External waterproofing, is a technique used to fix a leaking basement by revealing the structure's foundation and then applying the appropriate waterproofing material to it in order to create a foundation waterproofing system that will channel and distribute water away from the walls of the structure's base. This method of waterproofing is applied to the exterior of a building. This is the most common approach to fixing a basement's foundation, and it's also one of the best waterproofing strategies for stopping water seepage.

    Two layers of a rubberized membrane called Hydro Guard, Hydraulic cement, reinforcement mesh, an air-gap drainage membrane, drainage tile (also called weeping tile), and gravel measuring three quarters of an inch in size are used for waterproofing.

    There are many moving parts that must be considered from the outset of planning through the final stages of execution.

    • In any construction project, but especially those involving electrical or plumbing work, it is important to make sure that all utility lines are clearly marked before beginning the project. This includes everything from the utility company's power lines and gas lines to the sewer system and the phone and cable lines as well as any sprinkler systems.
    • For any project involving electricity or plumbing, it is essential to have all utility lines marked before beginning the work. Included in this category are things like water and sewage systems, sprinkler systems, phone and cable lines, electrical wiring, and other similar infrastructure.
    • Access Depending on the size of the project, you may need to take some unorthodox measures to get to the work site, such as crossing a fence or driving through the yards of neighbours. Naturally, we'll have discussions about all of this before beginning the project.

    How An Exterior Waterproofing System For A Basement Functions?

    Here's a rundown of the steps you can expect when A-1 Waterproofing comes out to waterproof the outside of your house.

    • The first step in house excavation is usually to relocate the plants near the foundation so that they can be replanted after the excavation is complete. When that is complete, A-1 will either bring in a mini excavator or start digging a trench by hand along the foundation. The size of the project and its footer will dictate the trench's depth. Typically, the depth of the trench will be several inches (or even centimetres) below the finished level of the footer. When water drains along the exterior of the foundation, it will be deflected away from the wall. Using this method, the wall will be protected from harm.
    • When our professionals are done digging the trench along the foundation, they will reinforce the dirt wall for your safety and fill the trench with gravel for the footer drain. Our footer drain will be safe and sound with this. The typical size is a 4-inch diameter perforated pipe. Vertical installation of a larger culvert pipe (12 inches in diameter) will take place at one end of the trench. Our sump pump will draw water from this well. In case future maintenance on the pump is required, the pipe will rise vertically to the top of the current grade. The 4-inch diameter perforated pipe is lowered into the drilled well in the pump house. After the work is done, a layer of gravel two to four inches thick will be placed over the drainpipe.
    • A sump pump is lowered into the culvert pump or pipe well after the drain and well have been installed. The extension pipe connecting the two must be long enough to reach the surface. The sump pump needs to be set up now so that it can be used later when water is used to wash the exterior wall's surface, when the trench will be full and the water needs to be drained. Installing the sump pump now is crucial.
    • Walls can be cleaned with a hose or powerful pressure washer, and then repointed. After that, the wall is pointed again. Then, the foundation is tuckpointed with cement to seal any cracks or missing blocks that could allow water to seep inside.
    • The rubberized coating should be applied after the surface of the foundation wall has dried and any cement tuckpointing has had time to cure. Depending on the material, this could be applied to the wall by spraying, rolling, or brushing. Coatings should be applied at a level higher than the target grade and should completely cover the surface area.
    • Backfill - After waiting for the rubberized coating to dry, the next step of backfill can begin. For the sake of protecting the freshly applied coating from being scratched or dented by heavy boulders or tools, great care must be taken during the backfilling process.
    • After the final grade has been reached, the plumbing must be finished by connecting the sump pump's drain to the downspouts or directing the water to a catch basin. Afterward, a cover is positioned over the top of the pump well for easy access.
    • Replant the Grass and Trees - Once the area has been cleaned up and the trenches have been tamped down, you can replace the landscaping.

    Water can't get into the basement through the foundation if the exterior wall is sealed off. Because of this, we can reduce the likelihood of flooding. In order to waterproof the exterior of a basement, you must first excavate the soil around the walls, then instal a moisture barrier, and finally, dimple board. You can reduce the amount of water that enters your home by taking certain measures. Putting in downspouts and gutters is a cheap and easy way to reduce water seepage.

    As a company, Hitch Property Constructions has been offering waterproofing services since 1996. Your home's downspouts should extend at least ten feet away from the structure. Your foundation may be strained by hydrostatic pressure and water seepage from nearby water sources. Next on the list is the landscaping next to the house's base. The soil around your home has a significant impact on the amount of water that will seep into your basement.

    In Milwaukee and its surrounding areas, clay makes up a significant percentage of the soil. If you have a basement waterproofing system installed on the exterior, you won't have to worry about any leaks or damp spots. Typically, an excavation will go down between five and nine feet, and its width will be between one and two and a half feet. If your home has any windows that are below grade, you'll need to have a window well built. From the bottom of the window well to the foundation of the building, a vertical weeping tile installation four inches deep is used.

    The exterior of a building can be made watertight in order to repair a leaking basement. It establishes a water management system that directs liquid away from the building's exterior. If you want to make sure that the exterior of your home is protected from water, waterproofing can be used. Water that runs along the exterior of the foundation will be directed away from the wall. It's crucial to get that sump pump in there right now.

    To prevent water from entering through gaps or missing blocks, the foundation is tuckpointed with cement. In Melbourne, Hitch Property Constructions has an answer that will reduce your workload and stress levels. It's easier to prevent water from entering your basement than to clean it up after it's already caused damage. A-1 is the company to call if you need the job done properly the first time around.

    Frequently Asked Questions About Waterproof Basement

    Exterior basement waterproofing is a proactive rather than a reactive way to ensure that you have a dry basement. Ideally, it is done while a house is being built. Still, exterior basement waterproofing can be undertaken with any basement, whether it is a basement of poured concrete or one of masonry block walls.

    The cheapest way to waterproof this foundation type is usually by installing an interior perimeter drain system.

    Though labour-intensive and expensive, waterproofing your basement from the outside provides the most efficient way of preventing water and moisture build-up around the house's foundation.

    The exterior waterproofing process includes excavating soil surrounding your home and repairing the leaks using a powerful sealant. Interior basement waterproofing systems are considered better and more effective in preventing wet basements.

    Install a waterproofing membrane. A heavy membrane coat, an asphalt-modified polyurethane material, can be troweled or sprayed on to seal the foundation wall against water from the outside. Elastomeric membranes are made of modified asphalt and exhibit great waterproofing characteristics.
