Water is one of the most persistent causes of structural deterioration in buildings and car parks. At H3 Construct, we deliver specialist structural waterproofing systems designed to protect reinforced concrete against moisture ingress, freeze-thaw damage, and chloride attack — all while maintaining durability and compliance.
We specialise in high-performance waterproofing solutions for car parks, podium decks, basements, and structural slabs. Using proven liquid-applied membranes, crack-bridging resins, and damp-proof systems, we ensure every installation meets BS 8102 and BS EN 1504 standards.
Backed by Constructionline Gold and CHAS Elite accreditation, our waterproofing systems are fast to install, long-lasting, and tailored to your structure.
