Filling gap between concrete slab and wall.

It s maybe 1 8 to 1 4 of an inch below your slabs. Gaps in concrete whether they result from cracks in the slab or occur between the slab and an adjacent surface can serve as openings that allow dirt moisture or insects into your home. The gap in question was previously filled with either fiberboard or concrete crack sealant but enough of it has deteriorated to conceivably allow moisture in. The straight line gaps between the slabs has enlarged and some cracks are as wide as 2 inches.

The water being blocked by the sealant will find another gap in your foundation to enter the home. The sashco slab sealant is one of the best concrete crack repair sealants you can buy.

If water seeps between the gap in the asphalt and a house foundation water can erode the foundation and cause serious structural problems for the house. It delivers high quality concrete adhesion and keeps cracks sealed. While the sashco slab is a bit on the expensive end it s completely worth it.
