Interior crack injections

Posted Mar 31, 2021 in Foundation Crack Repair, Waterproofing

Show­ing inte­ri­or cracks that have nev­er been repaired would be too easy. Let’s dive into the more chal­leng­ing crack repairs, the pre­vi­ous homeowner’s DIY repair.

We chose this par­tic­u­lar crack repair because this was attempt­ed at least two dif­fer­ent times. The first time the crack was repaired with an old school tech­nique that required chis­el­ing the crack out and fill­ing it with a prod­uct sim­i­lar to hydraulic cement. The sec­ond attempt was a new­er tech­nique with a flex­i­ble fix in a can. In the end, both repairs were unsuccessful.

1.) Scrape off the spray can materials on the wall to access the first repair.

2.) Chisel/drill out the old repair in the foundation wall. This step requires us to find the original crack within the foundation wall.

3.) Embed injection ports into the voids in the wall. Fill in chipped out voids with a quick set hardener and cover the crack with the epoxy patch. Additional epoxy will be needed around the ports and filled in the voids.

4.) Inject crack from bottom to top, from inside and outside of the foundation.

  • 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.
