Plate Load Testing & CBR Determination
Ensuring ground stability and safety for piling mats, crane bases, and temporary working platforms across the UK.
Why is Plate Load / CBR Testing Essential?
Failure of working platforms or foundations under heavy loads can lead to catastrophic accidents and costly delays. Testing is critical to:
- Verify Design Assumptions: Confirm the ground can support intended loads.
- Ensure Piling Mat Integrity: Provide confidence for safe piling rig operation.
- Confirm Crane Base Stability: Crucial for safe lifting operations (outrigger pads).
- Assess Settlement Potential: Predict ground deformation under load.
- Determine CBR Values: Provide key data for pavement and platform design.
- Mitigate Risk: Prevent equipment instability, accidents, and downtime.
- Meet Regulatory & Site Requirements: Often mandatory for high-load areas.

Our Ground Bearing Assessment Services
Plate Bearing Tests (BS 1377: Part 9: 1990)
In-situ determination of ground bearing capacity and settlement characteristics using various plate sizes (e.g., 300mm, 450mm, 600mm). Load applied via kentledge or reaction load (site plant). Essential for testing piling mats, crane outrigger positions, temporary haul roads, and foundations.
CBR Determination
Equivalent California Bearing Ratio (CBR) value calculation from Plate Load Test results (Modulus of Subgrade Reaction, k) using established mathematical relationships. Provides key input for working platform and pavement design verification.
