What is slabjacking?
Simply put, slabjacking can fix sunken concrete. Slabjacking involves drilling strategically placed holes into the slab and using specialised equipment comprising a portable pump and flexible hoses to fill these holes with a special grout mixture. Once any void is filled, the grout becomes pressurised, hydraulically raising the slab to the desired height. Thereafter, the holes are patched using a concrete mixture. The grout injected beneath the slab to raise it provides a stable base, thus strengthening the slab. Nothing needs to be moved off the slab, as the pump can lift the weight of the slab and anything you have placed on it.
