Approaching the problem from the exterior (the "positive side") seems to make the most sense to many people. We are all for it when applicable and necessary. One big draw back - cost! It takes a considerable amount of labor to dig down to the base of your foundation wall. Once excavated, we can provide concrete slab repairs, concrete sealing and install a new waterproofing membrane to the foundation walls. A drain tile is added to collect and dispose of the excess water. If there are obstructions, such as a driveway, porch, or garage in the way, they would need to removed and replaced.
There is another school of thought when it comes to waterproofing concrete foundations. Rather than stopping the water from the exterior, the water can be directed into a drainage system below the floor on the inside. The process is known as Interior Drain Tile. As a part of the installation process, holes are drilled into the bottom row of blocks. These weep holes allow for water to drain out from the hollows and into the drain tile system beneath the floor. We can install Interior Drain Tile Systems in both unfinished and finished basements, although the latter requires some prep work.
