Concrete Slab Stabilisation from Poly-Tech

Australian Fruits had real concrete issues with their high traffic unloading area. The everyday task of manoeuvring highly corrosive fruits by forklifts and pallet bins caused the concrete slabs to sink resulting in water ponding and egressing down the control joints.

Poly-tech utilised the following 6 step system to solve this unstable substrate problem:

Careful removal of damaged and separated concrete along the affected joint.
Use of expansion foam to recreate the control joint to reinstate the sides of the joint using specified epoxy mortar mix with a trowel finish.
Drill and inserted injection plugs to a specialised grid system.
Inject water in to the plugs to establish a steady water flow through the system.
Once flow established, convert to injecting resin which reacts with the water resulting in foam formation which stabilises the slab by replacing the water in the substrate with foam.
Cut control joint, insert backing rod and fill with polyurethane joint sealant.

The result. The slab lifted & leveled correctly totally removing water ponding problems.
