Expert Geoscience Consulting

Our story began with a passion for geology and its application in a world facing challenges, such as responsible, stewardly use of earth resources, respect for the environment, while acknowledging the need for selection of quality earth materials for a range of engineered and construction uses.
With a background in the realm of soils, rock, aggregate and construction materials engineering, a keen knowledge of the requirements and limitations of these materials informed our experience in developing practical approaches in investigation and exploration of new and existing geologic sources of construction materials; determining their extent, quality and value; highlighting potential issues; advising on extraction/mining and closure-reclamation plans; and supporting claims, disputes and litigation regarding these resources or products and construction made with these materials.

The focus of our services is on construction materials, in particular  construction aggregates, railroad ballast, and armourstone/erosion control rock,  as well as composite materials manufactured with aggregates, such as concrete, asphalt. Then there are also building cladding stone, ornamental stone, and rip rap/armourstone.

We have considerable expertise and  experience in problems related to sulphide minerals in rock and aggregate, such as pyritic heave, pyrrhotite degradation of concrete, and Acid Rock Drainage (ARD).

Additionally, we offer petrographic examination of concrete, per ASTM C856, and we have extensive experience in AAR assessment of concrete, and in the Damage rating Index (DRI) analysis of AAR-affected concrete.
