SMR UK is a family-run, Welsh company that manufactures its patented hydraulic powder products in Caldicot, with offices located in Hendy.

We supply the construction, civil engineering, and utilities sectors with innovative solutions for soil stabilisation and high-quality alternative to aggregates.

Operating through a national UK supply network, we work with utility companies, main contractors, and subcontractors across the UK and Northern Ireland, both on a product supply basis and through our contracting and recycling services, where we also carry out the mixing process.

Our low-carbon cementitious powder binders use existing moisture in the air and ground to significantly increase ground density (when compacted), delivering exceptional load-bearing performance. With only a 1.5–4% addition rate, they achieve 15–30%+ CBR.

Our product range supports multiple applications, from trench reinstatement, capping layers, sub-bases bases, in-situ stabilisation, and soil drying.

They enable the reuse of up to 100% of host-materials across a wide range of UK soil types, from utility spoil containing challenging clays and fines, to highly saturated materials, and even contaminated soils requiring specialist treatment.
