Earthworks Testing 

Testing of earthworks for engineering, building, construction and civils projects 
If you need to assess soils for earthworks for use in stabilised soils, cut and fill operations, bunds and layers then we can help. We undertake a broad range of classification tests to assess whether material complies to a variety of specifications including the Highways England Classes of fill. 
We can undertake full analysis of a wide range of earthworks material properties such as grading, shear strength, plasticity, CBR, sulphate levels, frost heave, pulverisation and much more. To support laboratory based testing we can also sample all materials and provide full compaction level monitoring through a variety of methods for that all important compaction percentage. 
We can help with specification interpretation and are sector leaders in our turnaround times. 
Sampled from all over the UK 
Test results are only valid if the sample is taken, transported and stored in full accordance with the test requirements so leave the sampling to us! 
Stabilised soils 
We are experts at providing tests and analysis for quality control for all stabilised soils. 
Site laboratories 
If you have large scale earthworks testing we can help with the set up of a dedicated site laboratory for your project
