To comply with specification requirements and avoid costly remedial works, control and testing of earthworks and other materials within a civil engineering project is essential. Nicholls Colton's expertise in earthworks and other construction testing spans over 40 years!

We carry out a range of sampling and testing activities in liaison with the client for Earthworks, Highways and other construction projects and investigations from the Leicester Laboratory (UKAS).

Construction Site Testing

• Sampling Fresh Concrete
• Making Concrete Cubes
• Concrete Slump Testing
• Sampling of Aggregates
• In-situ California Bearing Ratio (CBR)
• Plate Bearing Testing for Equivalent CBR, Ultimate Bearing Capacity, Modulus of Subgrade Reaction or Settlement

NCA activities include:

Earthworks Testing:

• Sampling of Earthworks (UKAS)
• MCHW Specification for Highway Works Appendix 6/1 Compliance Testing

Compaction Assessment (In-situ Density Testing) including:

• Nuclear Density Gauge Method
• Sand Replacement Density
• Corecutter Density
• In-situ CBR and Plate Bearing
• MCV
• Hand Shear Vane

A comprehensive laboratory service is also available to compliment the above activities.
