Such products can slow down a leak a bit, but they don't address the original problem - they only cover up the leak point.
Crack injections: This repair approach is generally only suitable for poured concrete foundations where seepage is originating from the walls and not floors. Masonry foundations, such as brick, stone or cinder block, are not ideal candidates.
Injecting an epoxy or polyurethane material into a crack can help prevent water from entering the basement, but some basement waterproofing companies regard this solution as a temporary fix and not a permanent solution. Exterior excavation: Exterior waterproofing involves excavating 6 to 8 feet down to the foundation wall footer and correcting drainage by installing new drainage tiles or a French drain system. Due to the extensive excavation required, exterior basement waterproofing is often more expensive than other methods.
However, it carries the advantage of excluding water from the home and requires little to no ongoing maintenance once the project is complete. This method addresses water after it's entered the basement and routes seepage areas to a sump pump system. These systems are less costly than exterior solutions, but they're less ideal for a finished basement. Andy Abeyta Community Dec. History Nov. Elijah Decious. Erin Owen.
A sump pump moves water out of your basement. Great article and even better information! I noticed some paint was peeling out from the walls, and it got me worrying. I think I better call a professional to check it out. I appreciate your information about how to know if your basement is poorly watertight sealed.
Signs Your Basement Needs Waterproofing The first step of waterproofing a basement is to know what to look for. Mold can also present a health risk if left unaddressed. Using a dehumidifier is a great mold mitigation method. Peeling Paint: Paint can peel off walls for many reasons; it may have been the wrong kind of paint or the surface may not have been properly prepared. Leaking Walls: Bare basement walls can leak and occasionally form damp spots and condensation.
This can be caused by leaking pipes behind the concrete, or by water seeping in through the soil on the other side of the walls. Dry Rot: This blackish-brown fungus usually appears as a byproduct of the decaying process and typically grows on wood.
It can grow as a result of leaks and excessive dampness. Flooding or Standing Water: If your home sits on a high water table, water could be finding its way into the structure through faults in the floor or walls. Regular flooding could also be the result of a plumbing or yard drainage issue. Different Ways to Waterproof Your Basement Although foundation repair and floor damage recovery should be left to trained experts, there are a number of waterproofing projects you can tackle on your own to prevent basement flooding and reduce the risk of intrusive moisture.
Buy a Dehumidifier If your basement waterproofing efforts are aimed at cutting down musty, subterranean humidity and condensation, a residential dehumidifier unit may do the trick. Choose Waterproof Carpeting Materials Carpeted surfaces can take a beating if your basement has water control issues. Apply Waterproof Sealant to Walls and Floor Cracks can sometimes appear in concrete or brick walls, allowing water to seep in from the outside.
Keep Wood Surfaces and Water Separate Dry rot can occur if water or excess moisture makes prolonged contact with wooden surfaces and structures — especially support beams and floorboards. Before You Begin Before you begin waterproofing basement walls, you want to know where your water is coming from. Step 1: Clean the Area First you'll want to clean up the areas you'll be waterproofing. Step 4: Seal Openings Use caulk to seal doors, windows, and window wells.
Step 5: Apply Waterproof Coating After your holes and cracks are sealed, use a waterproof coating on your basement surfaces. Related Products. G-Force 5 in. Ergo Grip Margin Trowel.

Really appreciate you taking the time to educate us on this. I would have never thought of not planting flower beds or bushes too close to a house, but it makes perfect sense. Waterproofing by no means is an exciting topic to write about, but you did an excellent job keeping it entertaining and not boring. Thanks a ton! Working in a flooding basement increases the risk of electrical shock or electrocution.
Turn off the power to the basement, and then use a utility pump with extension cords that reaches an upstairs outlet to get rid of the water. The pump will discharge the water to the surface of your yard via a garden hose.
When the basement is water-free, proceed with inspecting, fixing, and effectively waterproofing the basement walls. Photo: homedepot. Another area where cracks are commonly found is at the bottom of the basement walls. When a foundation is poured, its footing—a wide flat base made from concrete and reinforced steel, designed to support the walls—is poured first, and then the walls are poured on top after footings harden.
Hydraulic cement—which contains additives that cause the cement to expand and set rapidly—is mixed with water to a heavy putty consistency and then pressed into cracks with gloved fingers or with a putty knife follow mixing and application directions. As hydraulic cement expands, it pushes deep into cracks and crevices to form a watertight bond.
This can lead to water pooling around the bottom of a basement window and then seeping in. If your foil test showed that water is soaking through your basement walls and leaving them wet, seal the interior of the walls with a high-quality waterproof paint, such as DRYLOK White Extreme Waterproofer available from Home Depot. This type of sealant comes premixed and goes on just like a coat of paint.
