Exterior crack repair process

Posted Mar 31, 2021 in Foundation Crack Repair, Waterproofing

Exte­ri­or crack repairs are a great way to stop the leak before it can even get into the crack. This method saves the home­own­er the expense of hav­ing to remove a fin­ished wall or heavy obstruc­tions. The appli­ca­tion requires a six-step process of both exte­ri­or mem­brane and an expan­sive clay (sodi­um ben­tonite), that leaves a pro­tec­tive seal over the crack.

Crack repair 1
1.) Identify the location of the foundation crack. Remove the stone/mulch covering if needed.
