Fixing concrete slab - comfort!? I am buying a house in a couple weeks. The 2.5 ton...
I am buying a house in a couple weeks. The 2.5 ton gas/air part is going to be replaced. The concrete slab needs to be raise 1.5" on the front end as it have tipped. I am being told insead of lifting the 4x4' 6" sticky slab, just re-frame it and append new concrete to rank it out is as the dirt is settled. 1st off it is 37-45 degree now and pouring topical concreat on the old may not stick together. Should I drill holes contained by the old concrete slab so the unsullied concrete goes surrounded by there or should I used some type of reinforcment? Again, it single has to be raise 1.5". Thanks for any help!
Answers: That is a small plenty slab to lift up and compact sand or dirt underneath to angle it. A tractor with forks or a forklift would move up that no problem and hopefully they reinforced the slab.
Put a 2x4 under it for now(the 2x4 is 1.5" thickthen cut to the length you need) and when the weather warm up this summer dig down lower than the edge of the slab that requests raised and using some compassionate of large prybar heave the slab and backfill under it beside sand this will solve the problem with exceptionally little to no cost.
