Why Choose Below Grade Waterproofing?
Allied Coatings provides expert waterproofing solutions for new construction and existing commercial structures. We install long-lasting waterproofing systems below grade, below slab, and in a variety of high-demand applications to protect your property from water intrusion and structural damage.
Using high-performance waterproofing materials, we seal foundation walls, slabs-on-grade, elevator pits, and sump areas. For any structure with below-ground elements—such as basements, parking garages, or decks—proper waterproofing is critical to prevent moisture infiltration that can compromise the integrity of your building.
Our team delivers a full range of below-grade waterproofing systems with precision, care, and decades of experience. We use top-tier products and proven techniques to ensure lasting protection in even the most challenging environments.
