We know the science behind your concrete. Whether you need a thermal control plan, a concrete specification, or an expert witness, we can help.

More About Us

We approach concrete from the chemical, materials and structural engineering perspectives. Our team knows how to make things work. And we are LEED accredited and licensed as professional engineers in 23 states and three provinces.

Thermal Control Plan

Thermal Control Plan

A mass concrete placement needs a thermal control plan. We’ll help you meet the requirements—usually without cooling tubes.

What are concrete exposure classes?

The service environment for a concrete structure or pavement may pose challenges to its durability. ACI 318 categorizes them as freeze-thaw (F), sulfate (S), water (W), and corrosion (C). Each category has numerical rankings for severity. For example, an exposure class of S3 indicates the severest exposure to sulfates, such as for a concrete foundation in soil with a high sulfate concentration. The concrete may be subjected to more than one type of exposure. For example, a parking garage slab may experience freezing and thawing in the presence of water and deicing salts. This is both an F3 and a C3 exposure, so you need to design for both conditions.
