Premium Cable Sands &
Cement Bound Backfill Solutions
for infrastructure Excellence

Engineered for Performance. Trusted by Industry Leaders.

When it comes to underground utility installations, thermal efficiency, structural stability, and compliance are non-negotiable. That’s why leading contractors and engineers across the UK choose our Cable Sands, Cement Bound Sands (CBS) and Backfill materials—designed to meet and exceed ENA TS 97-1 standards.

Cable Sands:
Precision Bedding for Power & Data
Our ENA TS 97-1 compliant cable sands are engineered for high thermal conductivity, ensuring rapid heat dissipation from underground LV, HV, and UHV cables. Whether you're working on solar farms, rail infrastructure, or energy networks, our cable sands offer:
  • Consistent grading and density
  • Fast heat dissipation
  • Excellent compaction and stability
  • Reduced risk of cable overheating
Cement Bound Sands (CBS):
Strength Meets Workability

Our Cement Bound Sands are factory-blended, semi-dry mixes designed for trench reinstatement, duct bedding, and void filling. With mix ratios from 1:3 to 1:20, they offer:

  • Extended workability (up to 12 hours)
  • Low thermal resistivity (≤1.2 Km/W)
  • High load-bearing capacity
  • Compliance with ENA TS 97-1 and NGTS 3.05.07

Backfill Solutions: Built for Longevity

Built for Longevity

From trench stabilisation to duct protection, our backfill materials are tailored for civil engineering, utilities, and renewable energy projects. Benefits include:

  • Void-free compaction
  • Moisture resistance
  • Thermal regulation
  • Reduced maintenance costs

    Applications:
  • Cable bedding
  • Pipe protection
  • Solar and wind farm infrastructure
  • Rail and highway trenching
