We're innovative, hard working and we get the job done right from the science to the site. From our administration team, to the project managers and field crews, our employees are highly skilled and thoroughly trained professionals. We specialize in air quality testing and mitigation (Radon), underground tank decommissioning, sewer inspection & repair, plumbing services, directional drilling, environmental site assessments and environmental restoration.

"I hired Environmental Works on the recommendation of a co-worker. Not only was it the least expensive of the three bids I received but it was also the only company that offered a lifetime guarantee on its work. The entire installation of a radon mitigation system in my home took less than six hours. The company guarantees that its radon mitigation system can keep radon levels below 2.7 pCi/L. A three-month radon monitoring test, completed ten months after the installation of my mitigation system, indicated radon levels at 1.4 pCi/L. I am very pleased with the work that was performed at my home."

Structural Engineering questions, answered by experts

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.
