Our services

Compaction testing of sand beds and foundation layers

We perform precise measurements to check whether the applied sand or foundation material has been compacted adequately according to the RAW specifications and CROW guidelines. This prevents future subsidence and provides a stable base for roads or constructions.

Grain size distribution of sand, foundation material and recycled asphalt

We analyse the grain size distribution of materials such as sand, foundation layers, and recycled asphalt to determine whether they meet technical and environmental standards. This helps ensure proper drainage, stability, and workability. This is essential for building durable road foundations and avoiding delays or material rejections.

Asphalt delivery inspections

Ensure your asphalt construction meets all contractual and technical requirements before handover. We assess composition, compaction, air voids and layer thickness using asphalt core samples. With our independent evaluation, you reduce the risk of costly remedial work and can proceed to delivery with confidence.

PAH and DLC Testing

With a PAH and DLC examination, you show that you are environmentally aware and responsible in your handling of released materials. The examination determines the reusability of asphalt and foundation material, and helps prevent issues when offering it to asphalt plants or processors.

Layer Thickness Measurements

Layer thickness measurements and structural composition analyses provide insight into the structure and thickness of existing constructions. These measurements are performed using core drilling and specialised measuring techniques. The measurements are essential for renovation projects, quality control, and substantiating design decisions.

CROW 210 Research

When asphalt pavements are maintained or removed, it is essential to determine the options for disposal or reuse of the released asphalt. The CROW 210 research provides clear guidelines for this process.
