Advanced structural waterproofing solutions

Stopping nature seep into your asset

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.

  • Our Process

  • Initial Assessment

    We start with a thorough substrate inspection, moisture testing, and detailing of vulnerable areas. This ensures our waterproofing solution is tailored precisely to your structure’s condition and use.

  • System Selection

    We work with industry-leading manufacturers such as Sika, Triflex, and PCP Europe to specify waterproofing systems that suit your structure, whether it’s a podium, top deck, ramp, or below-ground space. All systems comply with BS 8102, BS EN 1504, and relevant local design codes.

  • Application

    We install liquid-applied waterproofing membranes, crack-bridging systems, and damp-proof barriers, using fast-curing MMA, polyurethane, or hybrid resins depending on the structure and access limitations. We also offer coatings that provide skid resistance and UV stability.

  • Details & Interfaces

    Critical interfaces — such as upstands, joints, and penetrations — are detailed using reinforced banding or flexible sealants to ensure continuous, defect-free protection.
