Point Pipe Repairs
Many problems found in pipes can be repaired with a spot repair also called a point repair or patch repair, when damage is located at a single point. To do this a liner is installed over the problem area inside the pipe and then cured.
This type of repair is suitable for areas where the client does not wish to dig up the drain and replace the pipe. It only takes a couple of hours to complete a repair and no site restoration is needed as would be necessary for a dig and replace project. We use a patch lining repair system for our point repairs that provides:
• Ease of installation
• Variety of Diameters and Lengths for Repair
• Permanent Repair
• Structural Repair
• Minimal inconvenience to the public/traffic
• No digging required
• Stronger than original pipe
• Seals infiltration
PMA’s pipe repair offers a structural repair to pipes, developed with extended design life, guaranteed to withstand all chemicals commonly found in waste water and sewer pipes.
The resin PMA uses for patching out-performs traditional resins in terms of substrate bonding, tensile strength and chemical resistance. The resin is 100% solid, making it both user-friendly and environmentally sound.
Quick-Lock is a mechanical alternative to patching, which does not require resin or curing. The sleeve is made from stainless steel and EPDM long-life rubber materials. Quick-Lock can be installed horizontally or vertically, above or below the water line and is suitable for sewer, stormwater or industrial applications.
Quick-Lock is used for:
• Cracked systems
• Fragmented pipes
• Infiltration and exfiltration
• Root intrusion
• Overcoming joint displacement
Rehabilitating Pipes In A New Housing Development
PMA recently completed a package of pipe rehabilitation works as part of a new residential development in Beverage.
The package included 54 rehab projects in total, consisting of a combination of Patching, Quicklock and Relining as well as CCTV inspections.
This project demonstrates PMA’s method of selecting the right solution for each defect to deliver the most cost-effective and efficient solution.
