Basement waterproofing is more than just waterproofing the interior of your home. The problem could also be things such as your yard not being graded properly, causing water to flow toward your home, rather than away from it. It could also be that you don't have enough drain tile around the exterior of your foundation, or your downspouts/gutter could be clogged. Contact a professional waterproofing company to help you get to the bottom of the problem. If you have these issues cleared away and you still seem to have water seeping into your basement, you could have cracks in the walls of your basement. In this case, you can apply a waterproofing paint to the walls of your basement following the instructions below.
Here's What You'll Need:
- Thick nap rollers
- Waterproofing paint (amount depends on the size of your basement)
- Shop vacuum
- Concrete patch/caulking
- Putty knife
- First, look over your basement walls and check for holes/cracks in your walls where the water could be seeping into. These holes/cracks will need to be repaired prior to applying the waterproofing paint.
- Take your hammer and chisel and begin to chisel out the holes/cracks to help get rid of loose material. You want the concrete patch/caulking to be able to have something to stick to. Once you have the hole/crack chiseled out, use a stiff bristle brush to remove all loose debris, then vacuum up the debris with the shop vacuum.
- You now have a clean area to work with and can begin filling in the holes/cracks using a concrete patch kit or caulking (depending on the size of the hole/crack, caulking works for most smaller cracks/holes, but the patch kit should be used for larger holes/cracks). Follow the manufacturer's directions on the concrete patch kit/caulking. Then smooth out the area using a putty knife. Repeat the process if need be. Then allow these areas to dry thoroughly before moving on.
- Next, you can begin applying the waterproofing paint to your walls. You can find this waterproofing paint at most hardware stores. Apply the waterproofing paint using a paintbrush to cut in around the walls/floor. Then roll on the paint to the walls. Allow the first coating to dry and apply a second coating.
To help keep your basement waterproofed, be sure to check your sump pump often to ensure that it is working properly. Install a second backup pump to be sure one will work in the case of a sump failure. Talk to a professional waterproofing company about other things you can do to prevent water from getting into your basement.
