Earthwork and Environmental Services

SEMA’s earthwork crews move millions of cubic yards of dirt every year, shaping the groundwork for everything from highways to water infrastructure. Our expertise covers grading, excavation, dewatering, erosion control, and surface water diversion, all while working in diverse environments that include waterways, animal habitats, and historically significant sites.

Beyond meeting environmental regulations, we take extra steps to minimize impact—whether it’s recycling materials, reducing waste, or implementing smarter land management practices. With every project, we balance efficiency and environmental responsibility, making sure the job gets done while respecting the environments we work in and the communities that rely on them.
