Imagine the frustration on an existing drain tile system fails and the whole basement is flooded.
In most cases, water leaking through where the wall and floor meet is a problem that has been present for quite some time. Typically, you can see water lining up to the second block.
It’s a common misconception that exterior concrete walls (cinder block walls) are the only walls that leak water.
A lot of homeowners think because the water goes up to the second layer of block that there is that much water in their basement walls. That isn’t necessarily the case – cinder blocks are very porous and the blocks can actually wick water up the face of the wall.
Usually when the water is that high on the block wall, it means there is about 3-4 inches of water inside the bottom block. That’s why you usually see so much water come out the bottom where the floor and wall meet.
It’s been said that water will seek its own level. Once the water hits the level of the floor inside the block wall, it will start to flood your floor. Most basements have a cold joint where the floor and wall meet (meaning it is not waterproofed between the two).
In places that have heavy, clayey soil (Saint Cloud, Richmond, & Cold Spring for instance), the water will pool even more easily. The pressure will build up behind the blocks, and water will leak through.
It’s a common misconception that exterior concrete walls (cinder block walls) are the only walls that leak water. That’s not true. Interior walls can leak, too.
Water will find its way in under the foundation and eventually cause a portion of the concrete to “float”. How do you fix this? Typically, a drain tile system that surrounds the basement foundation will need to be installed. See our waterproofing systems comparison and our Drain Tile page.
