Repairing Your Foundation
There are many reasons for this unfortunate situation and it really depends on the type of foundation you have in combination with the conditions that surround it. In order to find out what your specific problem is, you need to start with this – what type of foundation do you have? Below are the 3 most common types of foundations and each type of foundation has its own set of problems.
Poured Concrete Foundations
Common problems associated with Poured Concrete Foundations
The most common problems found with poured concrete foundations when it comes to moisture are:
Repairing Block Foundations
Concrete blocks used in construction are normally hollow. If the mortar that connects the blocks degrades in any one area, it allows water to fill up the empty cavity of the block. It then travels into surrounding block cavities until the water finds a way out. Water would be able to exit either by evaporation through walls into the basement or through a joint that has an active leak.
Repairing Rubble Foundations
It is never a good idea to do an interior membrane on a rubble foundation wall or poured wall. The interior membrane will guard the interior living space from the moisture coming through the porous concrete but the dampness trapped in the concrete through the winter months will freeze and the concrete can weaken and even crumble over time. The best waterproofing solution is the exterior repair requires excavating along the outside of the leaking wall or structure exposing the wall from the top down to the footing.
