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.

Typically this will be cracks in your foundation. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant. In the short term a sealant applied along this gap between your basement floor and wall may prevent leakage. The straight line gaps between the slabs has enlarged and some cracks are as wide as 2 inches.

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 sashco slab sealant is one of the best concrete crack repair sealants you can buy. There s no need to pay a contractor however. There s a wide ugly gap between my concrete outdoor patio slab and the slab my house is built on.

It doesn t allow moisture to seep through the crack which increases the lifespan of the concrete surface. 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 water being blocked by the sealant will find another gap in your foundation to enter the home. While the sashco slab is a bit on the expensive end it s completely worth it.

This will hopefully be the fix that keeps that wall of the sunroom nice and dry. So filling them should be a maintenance priority. Gaps can occur between asphalt and concrete for many reasons including weather changes vehicle inflicted damage or improper installation of the asphalt. It s maybe 1 8 to 1 4 of an inch below your slabs.

The driveway slopes down from my garage to the street. My concrete driveway has eight large 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. I poked at it with a chisel and removed the loose material.

It delivers high quality concrete adhesion and keeps cracks sealed. Water is coming up between expansion joint which is between masonry wall and concrete slab is. Then you can fill in the gap using sika flex self leveling sealant. This has left a channel of about 1 wide all the way around the edge of the wall.
