On-Site Testing

On Site Testing ServicesACS Testing offer a comprehensive range of professional On-Site Testing, 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 as well as a wide range of In-Situ testing on each of these materials. We offer both day and night works specific to the client’s requirements 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 including the Isle of Wight and South Wales.

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.
