Stabilization of the Foundation

When voids or gaps appear in cement slabs, they can become unstable. Slab stabilisation is a preventative and remedial procedure for restoring or stabilising a slab. The cement slab is stabilised to avoid or reduce cracking and other potential structural damage.

Repairing Cracks

Concrete can crack for a variety of reasons, from harsh force to chemical reactions to faulty original construction. We guarantee that we will thoroughly identify the origin of your concrete cracks, not only repairing the damage but also preventing future harm.

Repairing Cancer in Concrete

When the steel reinforcing a concrete slab rust, it causes concrete cancer. As rust spreads, it pushes the surrounding concrete out of place, making it brittle and cracking. Concrete cancer repair might be time-consuming, but with our help, your structure will be in good shape in no time.

Crack injection with polyurethane

United States trade Remedial specialises in using high-pressure injection devices to fix actively leaking fractures in concrete.


The leaking cracks are drilled out with a series of holes, and moisture reactive material is pumped into the crack under pressure until the reaction process has occurred, and the product forms a permanent and flexible seal for your concrete structure. Common places for moisture ingress are basement carparks, dance walls, concrete roofing, and any concrete structure exposed to moisture ingress.

Repairing Structural Cracks

Concrete is widely used in the construction industry for its strength, density, and longevity; however, structural cracking can occur due to movement and load bearing issues; these cracks can be repaired with an epoxy injection system by drilling a series of holes at specific depths and intervals, and an epoxy resin is then injected into the cracks, filling the voids and helping to prevent further cracking; typical areas include carparks, basements, roofing/floor slabs, and swiping; however, these cracks
