If your basement has seepage coming through the walls, it is time to waterproof it before the seepage turns into a really big problem. You can waterproof your basement yourself with just a few tools and a little hard work. See below for quick tips on waterproofing your basement both inside and out.
Check The Exterior
Before beginning any waterproofing inside the basement, you will need to prep the exterior of your home. Begin by looking around the exterior of your home near the foundation and the downspouts. You need to look for any low-lying ground near the foundation. If there is low ground near the foundation, it can cause water to collect there and eventually drain down into your foundation. Fill in the low ground with rocks or gravel, then add dirt on top of the rock. Next, check your downspouts to ensure they are draining properly. Add extenders to your downspouts so the water drains even further away from your foundation and in a place where it won't run back to the house
Protect The Interior
Here's What You'll Need:
- Waterproofing paint
- Masonry repair
- Stiff bristle brush
- Warm soapy water
- Inspect your walls for any cracks. For smaller surface cracks, you can fill those in with masonry caulk. For larger cracks, you'll need to repair them. To repair the cracks, you need to use a chisel and hammer to get rid of any loose concrete. Use a stiff bristle brush to clear away any more loose concrete. Then fill in the whole crack with masonry repair by following the manufacturer's directions. Allow the masonry repair to dry completely before moving on. Fill in any other large cracks this same way.
- Once the repairs you have made are all completely dry, you can begin wiping down your walls with warm soapy water, being sure to get into the corners as well. Allow them to dry completely.
- Using your brushes, begin applying the waterproofing paint to the concrete walls. Trim around each brick, then use the roller to go over the surface of the bricks. Paint on the waterproofing paint evenly and apply a second coat if necessary (once the first coat is completely dry).
If your basement has more than just slight seepage issues, you may need to have a sump pump installed or have the drain tile around your home repaired or replaced. Contact a professional basement waterproofing company for help.
