Part of homeownership is taking care of your home, including making sure crawlspaces and basements are waterproofed. When a home is built, the contractor should put waterproofing on the outside of the block or concrete for exterior basement waterproofing. However, depending on what the contractor uses and how much of the material is exposed to the sun, it could wear off over time. The waterproofing keeps water from seeping into basements and crawlspaces. If it is damp under your home, that could lead to mold problems inside. Waterproofing the basement or crawlspace before it gets out of hand will save you a lot of money in the long run. The waterproofing cost is based on the size of the home and the type of waterproofing that needs to be done. It could cost upwards of $5,000 to evaluate the site, repair any defects, waterproof the walls, install a sump pump or French drain, clean the window wells and gutters and epoxy injection.
Waterproofing Cost Per Square Foot
Waterproofing cost per square foot depends on what you need to have done as outlined above. It also depends on whether the basement or crawlspace blocks and concrete is cracked or if the original waterproofing is worn out. Items such as sump pumps and French drains are also included in the cost of waterproofing. In some cases, the contractor may be able to do something as simple as step the landscape away from the home to help with drainage. In other cases, you may need to excavate a French drain to carry the water away from the building.
To help with keeping water away from the house, you may want to install rain gutters. If you do have gutters, make sure the water exits at least 2 feet (0.61 meters) from the house. Running a dehumidifier in the basement will help take some of the dampness out once you get the problem fixed.
Basement Waterproofing Products
Several types of basement waterproofing products are available to waterproofing companies near me. Some are more expensive than others and some waterproofing products are made specifically for roofs while others are for basements and should not be exposed to the sun. Chemical waterproofing products include cementitious waterproofing, a liquid waterproofing membrane, bituminous coating, a bituminous membrane or a polyurethane liquid membrane.
In cases where this may not be enough to protect your home, you may have to add a french drain or another type of foundation drainage system. You may also have to add a damp-proof course (DPC). The DPC is a type of barrier that is laid horizontally on the basement’s walls. The barrier keeps the moisture in the basement from seeping up into the building.
Basements may be waterproofed from inside or outside, though the method of waterproofing from the inside is not as reliable as waterproofing from the outside since the water is still able to seep into the walls of the basement.
