Our front porch is a concrete slab. Underneath it is a stone floored room where the water tanks/pumps are located. The top block has been tilting forward for a while but during a recent rain storm I noticed the second block has a significant leak and I couldn’t ignore the problem anymore.
A contractor and separate excavator advised digging out the foundation, putting in a drain pipe, backfilling with gravel. waterproofing, re-doing the block with hydraulic cement etc. My issue is how to straighten and correct the block with the weight of the slab on top of it. The porch concrete slab is also connected to/supporting the roof above it.
