What is a Quick-Lock repair?
A Quick-Lock repair seals cracks, fractures and joints with a watertight EPDM rubber sleeve and a steel bracing ring. This mechanical solution requires no chemical products such as glue, laminates, or resins. EPDM rubber is used in a variety of applications where water-proofing is essential, like roofing and tank lining. The high-grade, V4A (316) steel bracing ring is made from materials with a long track record in drainage and sewerage construction.
We use three distinct types – Quick-Lock, Quick-Lock Big, and the Quick-Lock LEM System.
The basic Quick-Lock system seals pipes between 150 mm and 800 mm using robotic equipment and CCTV to install remotely.
Quick-Lock Big is for pipes wider than 800 mm and requires our technicians to enter the pipe.
Quick-Lock LEM System
The Quick-Lock LEM System is a liner end seal for UV-cured lining.
McAllister’s Quick-Lock repair service
As their name suggests, Quick-Lock repairs are fast – our technicians can install one in 15 minutes. They require no flow control measures, yet provide long-term solutions. Our Quick-Lock System in WRc-approved, and comes with a 50-year guarantee. Quick-Lock repair is suitable for most common types of sewer network damage including:
cracks, fractures, and holes
water infiltration or effluent exfiltration, particularly at joints
realignment and sealing of displaced joints
sealing dormant or unused inflows
liner end sealing
For remote installations, our technicians coil the Quick-Lock patch – the steel bracing ring and the EPDM rubber sleeve – around an inflatable packer mounted on a remote-controlled installation trolley. Using a CCTV camera, they winch this rig to the repair location. They inflate the packer, pushing the Quick-Lock patch against the host pipe. The packer engages a ‘reverse ratchet’ locking system, securing the patch in place. Our technicians deflate the packer and pull the trolley out of the pipe. They conduct a final CCTV inspection to inspect and record the repair.
Quick-Lock Big installations on pipes wider than 800 mm usually require one of our technicians to enter the pipe. They follow a similar procedure to the remote-controlled packing rig, but do so by hand.
The Quick-Lock LEM System is a liner end seal that secured UV-cured lining to the host pipe. Our technicians usually use this method when relining drains with water ingress, to ensure a permanent seal at each end of the new liner.
McAllister pioneered the Quick-Lock system in the UK. Today, we install over 250 each year. We offer a fast-response service. We have highly trained and experienced Quick-Lock technicians around the country, and significant stocks for common diameters.
