In reply to basement leak - what's the best fix by Jeanine Ruby on February 3rd, 2003 04:54 PM [Go to top of thread]

There is a water tite sealer you can use on the bricks to help keep water out. But it will not be a complete solution. Water is very invasive. A basement is basicly a pool in the ground. The deeper the basement the more pressure on the brick from the water. For every foot of depth, 1/2 pound of water pressure is exerted. So if your basement is 8 feet deep, there is aproximately 4 pounds of water pressure on the brick.

Even if you meticously apply the sealer, you will miss some spots and the water will find a way through, if the season is very wet. You can probably reduce the majority, if you can cover all the surfaces.

Brick is pourous and is not impervious to water.

If you had the ability, a french drain system would reduce or eliminate the water problem. A system of drains is installed on the inside of the basement, which drains into a sump basket and ejects the water back outside away from the home. A very costly proposal though.
Good Luck
