Years ago we had porch mudjacked. The contractors drilled holes in the porch, then poured in a concrete slurry which was supposed to support it. That worked for a while, but eventually most of the slurry washed out from under the porch and down the incline on the side of the house. Based on that past bad experience I started looking around for other solutions to our problem.
About that time we got a packet of direct mail coupons. Included was one for a company that did polyjacking. I did some research, and found out the process used expanding polyurethane foam instead of a slurry to lift up concrete. After checking out the company's credentials we signed a contract to have them do the work.
The technician came out this week. I was not able to watch his progress closely, but I understand it looked something like this:
Now our porch and walkway are nice and level. The void is filled and no critters will be able to hang out in there. I hope that this is the last time we have to deal with this issue.
