Filling Gap Between Concrete Slab And Wall

I m trying to determine whether to caulk the crack or fill it with some cement based patching.

Filling gap between concrete slab and wall.

My concrete driveway has eight large slabs. It s maybe 1 8 to 1 4 of an inch below your slabs. It doesn t allow moisture to seep through the crack which increases the lifespan of the concrete surface. 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. The sashco slab sealant is one of the best concrete crack repair sealants you can buy. 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. 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.

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 driveway slopes down from my garage to the street. However it will eventually fail in one of two ways. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant.

So filling them should be a maintenance priority. Typically this will be cracks in your foundation. Then you can fill in the gap using sika flex self leveling sealant. Gaps can occur between asphalt and concrete for many reasons including weather changes vehicle inflicted damage or improper installation of the asphalt.

This has left a channel of about 1 wide all the way around the edge of the wall. The screed and concrete around the edge of my concrete slab where the slab meets the external cavity wall was cracked. 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.

I poked at it with a chisel and removed the loose material. Water is coming up between expansion joint which is between masonry wall and concrete slab is. This will hopefully be the fix that keeps that wall of the sunroom nice and dry. Foam backer rods act to fill in space between concrete joints so you don t need to use a ton of self leveling sealant.
