I have been Sika foundation crack repair kit in the past 15+ years, and I do not remember going back to any of the repairs we have done. Does this mean the product is good or knowledge has a role in this ?
After visually inspecting the crack on the foundation wall, we would spray water along the way top to bottom.
Time to drill 1/8 inch wide holes in the foundation wall crack. Must drill 5 inch apart max from bottom to top.
After a quick round of water spray, ready to install the Insert/nipples. Hammer in the Inserts as far and as tight as you can.
Up next is patching the crack with a quick set concrete mix. Seal the crack and around the insert/nipples with concrete mix. It would take approximately 30 to 45 minutes to set.
The moment we’ve been waiting for, inject epoxy through the Insert/nipples starting from bottom to top. When epoxy comes out of the upper insert/nipple, it’s a clear indication that is ready to move up to the next insert.
Once the insert is full, hammer the cap into the insert/nipple. It will take approximately 10 minutes to see the epoxy expand. Successful injections will have epoxy coming out of the foundation wall above grade outside the house. (Through the parging).
