Quick-Lock remains the key to repairing pipes


Sewer Equipment Company (Aust), or SECA, as it is more commonly known, is Australia’s leading supplier of sewer and pipeline cleaning, testing, inspection and rehabilitation equipment.

For structural repair of trenchless pipes, the company offers the Quick-Lock solution.

The Quick-Lock system has revolutionized sewer rehabilitation thanks to its wide range of applications and high reliability.

Using heavy gauge 316 stainless steel with infiltration reduction with an EPDM rubber gasket, the Quick-Lock system completely seals and stabilizes damage by mechanical means, eliminating the need for chemicals and making it suitable for all piping materials.

The patented locking system ensures that the sleeve remains in a permanent position and, after rehabilitation, the sleeve has its own static capacity and absorbs the natural tectonic movements of the pipe.

The system can be used for stand-alone permanent spot repairs or for pre-coating stabilization work including heavy groundwater infiltration.

Quick-Lock Sleeves restore the structural integrity of a pipe and seal groundwater, and they are carefully designed to minimize diameter loss and survive any further rehabilitation.

For large pipes, THAT’S IT offers the BIG Quick-Lock Coupling, which permanently seals leaking pipe joints, radial cracks and longitudinal cracks in large pipes and manholes of DN800 and above.

The BIG sleeves are 20 cm wide and the system is made of V4A stainless steel of grade 1.4404 (AISI 316L) and an EPDM compression seal.

These materials are permanently resistant in municipal sewerage systems, while their suitability must be verified for use in industrial or polluted wastewater.

In the field

SureSearch has over 20 years of operational experience as a company, providing all aspects of utility survey work including location, non-destructive excavation, utility survey, mapping and conflict detection, video surveillance inspections, drain cleaning and pipeline rehabilitation offers.

SureSearch sales and development director Calyn Wilkinson said the company is relatively new to the pipeline rehabilitation business and using the Quick-Lock system is a good way to enter the market.

“SureSearch used the Quick-Lock system for sewer and stormwater rehabilitation,” he said.

“It has been used to seal joints, holes and also seepage through cracks.

“Due to the quick installation time and the absence of hardening of the material, it has a great advantage over the cured pipe method (CIPP).

“More installations can be done in a shift and if traffic control is required, this limits the amount of money spent on traffic control shifts. “

Quick-Lock tips reinforce a CIPP liner at its most vulnerable points, the ends.

This mechanical solution prevents infiltration or exfiltration of the liner and host pipe for the life of a fitted liner.

It is particularly effective on EX, Spiral and UV cured coatings, and it is stronger and easier to install than other end caps, making them very beneficial for any long term waterproof coating project.

Quick-Lock systems can be purchased from SECA warehouses or from SECA sales representatives nationwide.
