Engineering Laboratory

Construction material testing, also known as CMT, is a process used to test materials before they are given the all-clear to be used in new building projects, extensions, and refurbishments.

Soils:

• Undisturbed soil and compacted soil fill are commonly used to support buildings and pavements. Soil strength and compressibility necessary to support buildings and pavements are highly dependent on the soil plasticity, density, and moisture content. Laboratory classification, compaction, and strength tests are commonly performed to determine if material proposed for use as soil fill satisfy specifications requirements. Field density tests are performed to determine if the level of compaction satisfies requirements. Our personnel are familiar with all laboratory tests and field tests/observations necessary to determine if soil fill placement conforms to project requirements;



Aggregate Testing:

• Sieve analysis;
• Deleterious materials (Mn/DOT and ASTM);
• Specific gravity and absorption;
• Soundness;
• Unit weight;
• Insoluble residue;
• Insoluble residue.



Other:

• Compressive strength testing of hardened concrete;
• Testing the dynamic modulus of deformation;
• Deep foundation testing (rammed aggregate piers, driven pile, helical pile, auger cast pile, drilled piers/caissons, and rigid inclusions);
• Double ring infiltrometer testing.
