Our On Site Material Testing Services
ACS offers a comprehensive range of professional on site material 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.
In addition to material sampling, we offer a wide range of in-situ testing on each of the above materials. Our services can support both day and night work, as we understand that some projects are subject to certain working timeframes.
We deliver our on site material testing and sampling services across the whole of the South of England. If required, we can also carry out testing and sampling across South Wales and the Isle of Wight.

On Site Concrete Testing
Our experienced technicians provide fresh concrete sampling and testing to show compliance with site-specific requirements. Our on-site checks provide assurance that certain aspects are in conformance, providing quality control before concrete hardening. Cube samples can also be taken to determine hardened concrete compliance.

Coring | BS EN 12697-27 | Obtaining samples for laboratory testing, to include; depth checks, visual logs and compaction assessments. |
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 material testing lab 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.

Frequently Asked Questions
What is on site material testing in construction?
On site material testing involves assessing the quality and compliance of construction materials directly at the project location. ACS provides UKAS-accredited on site material testing for concrete, soils, aggregates, and bituminous materials to ensure immediate quality control.
Do you provide on site soil testing services?
Yes. ACS offers comprehensive soil test on site services across the South of England and South Wales. Tests include plate bearing tests, CBR, dynamic cone penetrometer, and hand shear vane to assess soil strength, stability, and suitability for construction.
What is a soil compaction test on site?
A soil compaction test on site determines the density and compaction level of soil layers during earthworks. ACS uses methods like the sand replacement test, core cutter, and nuclear density gauge to ensure ground conditions meet design specifications in line with BS 1377 standards.
What on site concrete testing services are available?
ACS provides full on site concrete testing, including:
- Slump testing
- Air content & wet density checks
- Fibre content analysis
- Concrete cube testing & coring
These tests are performed in accordance with BS EN standards to verify fresh and hardened concrete quality before and after placement.
Why choose a UKAS-accredited material testing lab for on-site services?
Using a UKAS-accredited material testing lab like ACS ensures testing is performed to recognised national standards. Accreditation guarantees the reliability, accuracy, and traceability of on-site results for soils, concrete, and other materials.
