Top-Hat & Lateral Joint Sealing (Connection Repair)
Need to Seal a Leaking Sewer Junction?
Sectors We Serve
The Structural Solution for Leaking Connections
In the UK’s ageing sewer network, the connection between a lateral pipe and the main sewer is the number one failure point. Civil Connect provides a permanent, trenchless solution: Top-Hat Lateral Joint Sealing.
We utilise advanced robotic technology to install a “Top-Hat” profile a resin-impregnated liner that seals both the main line interface (the brim) and extends up into the lateral pipe (the crown). This creates a seamless, watertight, and root-proof sewer junction repair without the need for disruptive open-cut excavation.
Why Use Top-Hat & Lateral Sealing?
Stop Infiltration & Exfiltration (I&I): Displaced joints allow groundwater to flood the sewer (increasing treatment costs) and sewage to leak out (polluting soil). Our lateral drain repair seals the junction completely, guaranteed for 50 years.
Prevent Root Intrusion: Roots seek out the weakest point: the join. By creating a physical GRP barrier, we stop roots from re-entering, preventing future blockages.
Section 104 Adoption: For developers, a leaking lateral connection will cause a Water Authority to refuse adoption of your new estate. We provide the drain connection sealing required to pass CCTV inspection and secure handover.
Our Robotic UV-GRP Installation Process
We bridge the gap between complex engineering and on-site agility.
Robotic Preparation: We launch a robotic cutter to grind away mineral deposits, roots, and intruding edges to ensure a perfect mechanical bond.
UV Curing Technology: Unlike traditional ambient-cure resins that take hours to harden, our Top-Hat repairs use high-intensity UV light to cure in minutes.
Verification: Every installation is backed by an automated curing log and high-definition CCTV verification, ensuring total traceability for WRc and Water Authority standards.
