Why this method works

Proven across hundreds of civil sites.

Short possession windows

Lifts completed within night possessions and short road closures, back in service before peak traffic.

Designed to specification

Schemes engineered to your spec, DMRB, Network Rail, CAA, with resin grade, density and lift profile signed off.

Permanent void filling

Resin penetrates and seals voids in the sub-base, stopping further migration and washout for good.

Lower carbon than replacement

A fraction of the embodied carbon of full slab replacement, and no landfill of broken concrete.
