SPT Hammer Energy Calibration/Verification

The Standard Penetration Test (SPT) is the industry standard for the sampling and analysis of soils within the geotechnical design profession; providing a cost effective means to estimate strength and response characteristics of various soil types at nearly any depth.

CAMP Monitoring

A Community Air Monitoring Plan (CAMP) reduces the potential for airborne contaminant releases from a project site and provides a measure of protection for communities downwind of contaminated sites. This is accomplished by establishing action levels in response to real-time monitoring for volatile organic compounds (VOC) and particulates (i.e., dust).

Concrete Shrinkage and Cracks

I had a college professor that said concrete was guaranteed to do two things…harden and crack. Hardened concrete is the result of hydration, a chemical reaction between cement and water. The loss of water from the concrete as it cures results in a reduction in concrete volume, or shrinkage.
