ACS Testing offer a comprehensive range of professional on site testing services, all carried out by our fully trained site technicians. We provide our clients with a UKAS Accredited sampling of materials including aggregates, bituminous, concrete, soils and water monitoring. We also offer a wide range of in-situ testing on each of these materials. We offer both day and night works, as we understand some projects have certain working timeframes.

We provide our on site testing and sampling service across the whole of the South of England. We also provide our testing services across South Wales and the Isle of Wight.

On-Site Concrete Testing

Our trained technicians provide fresh concrete sampling and testing to show compliance to site specific requirements. Concrete is supplied to meet a specification. On-site checks provide assurance to certain aspects are conformed to providing quality control prior to concrete hardening. Cube samples provide hardened compliance to indicate specification.

Plate Bearing Test Services

Analytical Construction Services (ACS) offers comprehensive on-site plate bearing tests, also known as plate load tests, to determine a material’s ability to withstand different applied pressures and to estimate its ultimate load-bearing capacity.

During a plate load test, our trained technicians will apply the specified load to the test surface and analyse the resulting deformation. This test provides valuable insights into the likelihood of any movement or settlement of the ground – establishing how well the material will perform under the required conditions.

Our experienced team will ensure your plate load testing requirements are clearly understood, efficiently conducted, and carefully reported. This will provide you with accurate and reliable data to drive your project’s success.
