Slabjacking Concrete Sidewalk - June 8th 2017


Slabjacking Concrete Sidewalk

Q. On the east side of the house the sidewalk is right up to basement wall and water runs to the house. On the inside it is coming through on a rusted tie, is there a product that would seal from the inside?

A. Before fixing the problem from the inside, you will have to correct the drainage problem caused by the sloped sidewalk to have the water run away from your house.  This can be repaired by having a concrete company complete a process call slab jacking.  Over time, concrete will settle and may require lifting. Slab Jacking involves pumping a dense combination of clay, sand, water and other materials through a hole drilled into the concrete by a special machine (not DIY). The mixture is injected by hydraulics under the sunken concrete. Slab Jacking often improves drainage problems associated with water seepage but it will not completely solve water problems if other problems exist in your drain tile perimeter drains.

Contact Shell Busey’s Home Services at 604-542-2236 to have a drainage professional come out and view the project. Once the water seepage problems are resolved, your next step may require a penetrating crystallization sealer to be applied to the concrete surface and walls.  To repair the area of the inside wall where water is seeping around metal form tie, use hydraulic cement.  Hydraulic cement comes in a powder; you mix it to a putty like consistency.  NOTE: work quickly following the instructions for it cures very quickly.  It’s just that easy!
