![]() ![]() This is why water drainage in a block foundation also uses dimple board. Now, letting the water out through weep holes will just release into your basement- unless you direct it. (Or both.) It can also cause the block to crack and further decay. If it’s in there long enough, it can stagnate, or cause mold to grow. You don’t want the water in the block’s core to stay there. You need weep holes in block foundations to release the water that collects inside the blocks. If you look at the picture we used to illustrate geochannel, you’ll see small holes in the blocks above the footer. Weep holes are holes that are literally drilled into the bottom row of concrete blocks of your foundation.

There are a couple different kinds of water drainage that can be used, depending on the type of foundation and floor you have in your home. Hydrostatic pressure can’t be stopped, because there’s no way to prevent it from raining. It may not be in the same place- or on the same wall- but it will happen. If you don’t, you can expect to have more water and cracks developing later. If you have water in your basement, you’ll need to deal with that in addition to repairing the cracks. How To Resolve Water Intrusion in a Block Foundation So whatever water you see in your basement, you can be sure there is more in your wall. It may fill up the hollow core of the wall for several blocks before it starts seeping through the interior side. Concrete blocks have hollow cores, so when water seeps through the exterior side of the block, it can collect in this open center. Gradually, this water accumulates until it is applying pressure against the wall.īecause concrete is a porous material, the water will eventually seep in. The excess water spreads out, because there’s nothing in its path to stop it- until it runs into your foundation. Hydrostatic pressure occurs when there is more water in the ground than it can absorb. We can say that with confidence, because the number one cause of foundation cracks is hydrostatic pressure. These cracks may not let in water right away, but they will eventually. The first sign you have a problem? Is usually a crack in the wall.
