Waterproofing Membrane & Concrete Waterproofing Services

Many structures are designed that are predisposed to holding water, which can lead to problems if the surfaces are not completely water tight. Most building structures need some sort of concrete waterproofing as concrete is naturally porous. Installation of a continuous waterproofing membrane or polyurea coatings on slabs, foundations and other surfaces potentially exposed to inundation can eliminate ingress of water and protect the structure and foundations.
