Sub Surface provide Plate Bearing Tests (aka Plate Loading Tests) Nationwide as described in BS1377: Part 9: 1990: Soils for Civil Engineering Purposes. A Plate Bearing Test determines the ultimate bearing capacity and settlement of the ground for working platforms, crane outrigger pads and piling mats.
If you require testing for roads, car parking, pavement design, etc. please go to CBR Test.
Plate Bearing Test Procedure
A Plate Bearing Test is carried out at ground level to shallow depth and uses a steel plate, generally 300mm, 600mm diameter or greater. A tracked excavator (13tonne minimum) is required to provide a deadweight. A hydraulic jack is then used to apply pressure to the plate.
The working pressure (in kPa) of the temporary structure is required and pressure is applied in increments to the plate up to three times the working pressure, recording the settlement of the ground.
Subject to site conditions and loading requirements, we typically undertake between 4 – 6 Plate Bearing Tests per day and provide fast mobilisation with a professional, reliable and competitively priced service.
