Anyone used this company to raise / level their house. We have had a quote to use resin injection to the ground below to re-level the house. This as opposed to re-doing the ring foundation and replacing some piles. Anyone had experience, or comments. It's not cheap.....

The cost we have been quoted is huge. Were you happy with your cost?

We have just used them for an EQC claim. Very professional/precise and void/ some levelling issues were sorted on the concrete slab. Have used another company too on another property and Mainmark's job was far superior. Definitely recommend them.

You realise its only a band aid fix??
I was involved in relevelling a two storey brick/ concrete house 235 mm at one end as it had subsided.
I drilled piles with cages/ concrete and then used jack plates bolted into the ring foundation then jacked it back up level, let it settle of 6 months and did final adjustments then concreted over the jacking plates, it wont go anywhere now as its supported by the piles, not the same ground thats subsided which is what would happen pumping resin under the slab.
In this case the double garage concrete floor lifted with the house so grout was pumped under the floor to just fill the voids so the garage could be used and the floor take the weight off cars.

Thanks. The mainmark solution is guaranteed for 10 years but I have not read the fine print yet. Your method is an option we have been considering, but the resin solution is no mess, no fuss, and non-intrusive. I'm on the fence...

I'd say replacing a few piles and repairing the ring foundation would be a much better repair.

we had a slab done it may be better with piles to redo but you cant with a slab they did the art center in town the only other way to fix slab was pull house down even eqc where going to fix the same way
