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.

2.) Use the posthole digging tool to remove dirt/clay. Continue to trench all the way to the footing. Wire brush foundation wall to ensure that foundation crack goes straight down and does not angle. If crack angels, please refer to exterior membrane repairs.

What our customers say

  • You and your crew did a great job in our base­ment and crawl­space. You went the extra mile to insure that all of our water seep­age prob­lems are over. We would rec­om­mend you high­ly to oth­er peo­ple. Your qual­i­ty and time­ly work out­match­es all the others.

  • Thank you for final­ly get­ting rid of my flood­ing prob­lem. I had almost resigned myself to liv­ing with the Black Lagoon in my base­ment. You were able to iden­ti­fy the real prob­lem with my leak by using some empir­i­cal evi­dence rather than guess­ing and charg­ing me for fan­tas­ti­cal projects. Above all, you talked to me as if l am an intel­li­gent per­son instead of ​“the lit­tle lady” who needs her hus­band to make a deci­sion. Final­ly, the extent and care of your pro­pos­al, with its exten­sive pic­tures, con­vinced me that you are an hon­est bro­ker. My base­ment stayed dry despite the recent tor­ren­tial rains. I would be hap­py to rec­om­mend your work.
