What is SMR?

SMR Stands for

Structural Material for Reinstatement, a cementitious binder that when combined with excavated spoil, creates a compliant capping and backfill material. SMR can be used for both backfill for Reinstatement and Soil Stabilisation.

SMR works by

bonding spoil particles, increasing density and strengthening by up to 600%, when compacted. SMR dries and stabilises excess moisture, ensuring optimum compaction and an impermeable final result.

SMR is a Superior Alternative to Traditional Backfill Methods like Type 1

It enables the re-use of almost 100% of the host material on-site, diverting waste from landfill and eliminating the import of aggregate.

SMR UK Binders can produce the following products:

  • Hydraulically Bound Materials (HBM) as per BS EN 14227
  • Hydraulically Bound Materials as per the Specification for Highways Works vol. 1, 800 series
