Cured-In-Place Pipe (CIPP) Relining
CIPP technology allows us to install a seamless, high-strength liner inside existing pipelines,restoring functionality and preventing leaks without the need for excavation.
Curing Methods:
- UV Curing: UV light is used to rapidly cure GRP liners, offering faster installation times, increased strength, and enhanced durability.
- Steam Curing: Steam is introduced to cure the liner efficiently, providing a reliable and uniform hardening process.
- Hot Water Curing: Hot water is circulated through the liner, accelerating the curing process for larger-diameter pipes.
- Ambient Curing: Used for smaller diameter pipes and shorter lengths, this method relies on ambient temperatures to cure the liner without additional heat sources.
Features & Benefits:
✔ Fast Installation – Various curing methods ensure project efficiency.
✔ Extended Lifespan – 50+ year durability.
✔ Eco-Friendly – No excavation required.
✔ Versatile – Works for sewer, stormwater, and industrial pipelines.
Applicable for: Municipal networks, industrial wastewater, and culverts.

Spray-In-Place Pipe (SIPP) Relining
SIPP involves applying a protective epoxy or polyurea coating inside pipes, sealing cracks
and preventing corrosion.
Features & Benefits:
✔ No Diameter Reduction – Thin yet strong coating.
✔ Safe for Drinking Water – AS/NZS4020-approved resins.
✔ Ideal for Small Pipes – Works in tight spaces.
Applicable for: Water mains, industrial systems, and commercial plumbing.

Advanced Repair Techniques
Smart Lock Stainless Steel Sleeves
For localized pipe damage, we use Smart Lock sleeves, which instantly restore pipe integrity
without curing time.
FFRP ASOE Pipe Liners
We offer FFRP ASOE pipe liners, an innovative solution for pressure and gravity pipe
rehabilitation. These liners provide high-strength reinforcement while maintaining
flexibility, ensuring a long-lasting solution for damaged infrastructure.
Epoxy Foam Infiltration Sealing
For groundwater infiltration, we apply high-strength epoxy foam, ensuring a watertight seal
in areas where other methods may not be viable.
Design Life & Compliance
We provide customized solutions with design life options ranging from 25 to 100 years, meeting the most stringent international standards:
- ASTM F1216-16 – CIPP rehabilitation for sewer and stormwater pipelines.
- ASTM F1743 – Pulled-in-place installation of cured-in-place liners.
- AS/NZS 2566 – Structural design for buried flexible pipelines.
