Repairing a settled concrete slab

[rwsaunders]

Three dead groundhogs later, a section of our 22 year old patio slab settled and I was perplexed as to what to do. I found this firm that injects limestone slurry under pressure to lift sunken slabs and 1 hour later, magic. I’m waiting on the epoxy filler to blend in some sand and sandstone pea gravel and then I’ll seal the slab…very impressed and pleased.
