At Brownfield Solutions, we provide professional in-situ testing as part of our on-site testing services. These tests deliver critical data on formation materials, helping to inform structural design, construction quality assurance, and earthworks planning.
CBR testing is a widely used method for evaluating the strength of subgrade soils, sub-base, and base course materials in pavement and road design. The test measures the resistance of the material to penetration under controlled conditions, comparing it to a standard crushed rock material. It provides CBR values, which help engineers design pavements, roads, and other load-bearing structures and ensures regulatory compliance with highway construction standards.
Plate load testing is used to determine the bearing capacity and settlement characteristics of soils for foundation design, crane bases, and pile mats. The test involves applying a controlled load to a steel plate positioned on the ground and measuring the resulting deformation. It provides critical data for design, ensuring that structures are built on stable ground and is used for verifying the compaction and performance of soils, sub-base materials, and fills.
LWD testing is a portable, rapid, and non-destructive method for assessing the stiffness and compaction of soil layers. It is commonly used for road construction, embankments, and backfill materials where quick, on-site data is required. It helps verify subgrade and base layer compaction, ensuring compliance with construction specifications and is a cost-effective alternative to traditional plate load testing, particularly for earthworks and infrastructure projects.
