CCIL CERTIFIED

Terrapex’s Geotechnical Engineering division, formerly known as Alston, operates two comprehensively equipped materials testing laboratories; our Toronto facility is CCIL Certified for concrete and aggregate testing. We also offer the convenience of a mobile aggregate testing unit.

In addition to routine soil and aggregate testing, our Toronto facility can perform specialized geotechnical testing including small and high displacement shear strength measurements,
one-dimensional consolidation tests, California Bearing Ratio (CBR) and permeability testing.
