How to Fix a Leaky Basement


Leaky basements can create the ideal conditions for mold and mildew growth, serve as breeding grounds for insects and rodents, compromise your home foundation, cause costly water damage that threatens safety and reduces value, and potentially increase insurance premiums.

Waterproofing companies can repair basement leaks in several ways. The first step is to identify the source of the leak.

Identifying the Source

Leaky basements can be more than a mere nuisance. They can also damage carpets, wallpaper, furniture, and belongings and compromise the structure of your home, causing sewage to backup into it. To avoid this scenario, it’s crucial that homeowners understand what causes basement leaks as soon as possible in order to identify and rectify them quickly.

Leaks can originate from internal or external sources. To identify the source, turn off all appliances and faucets in your house before checking your water meter to see if its reading has changed. If it has, this suggests plumbing issues as a likely source.

Another common source of basement leaks is the groundwater or soil around your home’s foundation. Rain or melting snow soaking into the soil can exert hydrostatic pressure against its walls, forcing water through cracks and gaps into leakage points, resulting in leakage issues.

Install gutters and downspouts around your home to reduce groundwater or rainfall accumulation and the chance of ingress by installing gutters and downspouts with proper grading to redirect surface water away from its foundation and install window wells that help divert snowmelt away from it as well as to redirect surface water towards window wells which redirect it away from it as well as inspect basement windows for any rotting frames or gaps in seals that might allow ingress of groundwater or rainfall.

Sealing the Cracks

Once you are ready to embark on your basement crack repair project, start by making sure the area is free from standing water; any topical sealant used will adhere less effectively and adhere to its desired result.

If your basement has become flooded, you must pump out all of the excess water before proceeding with any work. Standing water increases the risk of electrical shock, so make sure any drains are closed off before discharging it outdoors.

Non-structural basement wall cracks may be sealed using liquid rubber sealant, as the product dries into the color of concrete without bleeding and can be easily cleaned up afterward. Furthermore, its non-bleeding formulation and ability to withstand minor foundation movements make it an attractive solution for cracked basement walls.

Cracked concrete foundation walls can be filled from within with an expanding urethane solution without needing to remove any of the drywall. However, this method is unsuitable for block, brick, or stone foundations as an epoxy injection cannot be administered directly into these foundations.

Large cracks such as stair-step, or an experienced waterproofing contractor should always evaluate zigzag cracks as these may be structurally significant and require further work. A qualified waterproofing contractor can assess these cracks and provide recommendations for repairs; additionally, they can review your drainage system to ensure downspouts point away from the house to reduce extra water accumulation around its foundation.

Replacing the Waterproofing Materials

Once a leak has been identified, any waterproofing materials and damaged portions of the basement that have been affected must be replaced to ensure it won’t recur. Doing so ensures the leak has been successfully fixed while keeping future problems at bay.

Hydrostatic pressure is often the culprit behind floor cracks and cove seepage. It occurs when your soil becomes saturated with water, creating hydrostatic pressure on the foundation walls and floors of your basement. For this reason, it’s essential that gutters remain clear of obstructions and your yard has been graded appropriately so water drains away from rather than toward your house.

Interior waterproofing solutions such as interior drain tile are often necessary to permanently resolve this type of leakage in a basement. The tile catches groundwater through its perforations and channels it into a sump basin and pump system.

Poured concrete wall cracks may also leak through into the basement when saturated soil puts pressure on them, allowing water to seep in from outside and pressurize the walls. Our waterproofing crews specialize in fixing this type of leak by digging down to uncover the wall from its footing, then chiseling away any concrete that has become dislodged before injecting expanding polyurethane foam to form a flexible yet permanent seal that prevents future re-openings of cracks in concrete walls.

Keeping Your Basement Dry

Finding the source of basement leaks quickly is of utmost importance since untreated leaks can create numerous issues if left unattended for too long, aside from ruining floors, walls, and stored items and creating damp environments prone to mold growth that is unhealthy for anyone – particularly those suffering from allergies, asthma, or respiratory conditions. In addition, rotting wood damage could threaten the structural support systems of your basement and can endanger those living or working below your home.

If your basement leak is due to rainwater seeping into it from outside sources, installing gutters as soon as possible is critical. Gutters catch raindrops and direct them away from your house’s foundation via downspout extensions; otherwise, check that if they are already present, they have them installed!

Hydrostatic pressure is one of the primary reasons that groundwater enters a basement, and to reduce this pressure, it’s vital to provide somewhere for it to go. One option for doing this is digging up against footings and sloping it away from your house or installing interior drain tile (perforated pipe installed beneath basement floor which absorbs groundwater, transports it through its system to your sump pump and then back out again – plus maintenance-free operation!). Drain tile systems work similarly and take in groundwater intake before transporting it out again when discharging back out from where it came in or taking in groundwater from its source in and discharging out before discharging into your basement again – either way!
