The company’s range of Trenchless Technology systems, which include the Ex method, Enviroliner and Tiger T, are well known and in the last 12 months alone more than 130 km of linings have been installed for various authorities throughout Australia.

The company has invested considerably in the purchase and development of innovative technology and as part of this ongoing response to the needs of the market Kembla will be introducing two new systems that have been added to their portfolio at the upcoming International No Dig in Brisbane – the AMEX-10 seal and Channeline GRP lining.

Amex-10

The AMEX-10 seal is a low profile mechanical seal that has been used worldwide for over 25 years for the internal sealing of leaks in pressure pipes. Kembla has an agreement in place with AMEX-10 for the exclusive rights in Australia.

The rubber seal is positioned to span the leaking joint. Two stainless steel bands are then hydraulically expanded against the internal surface of the seal, compressing it against the internal wall of the pipe. Once installed, each seal is pressure tested to confirm it is watertight.

The seal is able to accommodate substantial joint movements and can be fitted to all pipe sizes where man access is achievable, without the costs of trenching and associated services. AMEX-10 seals are suitable for sealing pipe joints and leaks in diameters from 500 mm to 6 metres in pipes made of steel, cast iron, reinforced concrete, PVC, AC, GRP and PE and can withstand pressures up to 20 bar.

The seal can be installed in almost any shape and the materials for the rubber seal and the steel retaining rings can be varied to suit potable water, sewer, storm water, gas, oil and chemical pipes. AMEX-10 seals do not rely on chemical adhesives or coatings and can therefore be rapidly installed and tested.

By eliminating the need for excavation to the outside of the pipe, considerable cost savings can be made along with the reduced risk of disruption to services or other works.

Channeline

The Channeline system is a structural man-entry lining system consisting of one piece or multisectional glass fibre reinforced plastic (GRP) panels, manufactured from a selection of thermosetting resins, and reinforced with glass fibre chopped strand mat. A glass surfacing tissue layer provides additional corrosion protection and abrasion resistance.

The outer surface of the liner is treated with a bonded inert aggregate to enhance the adhesion to the backfill substrate, usually grout or concrete.

Channeline GRP lining panels are manufactured to fully comply with the WRC materials standards for GRP (Guidance note WIS 4-32-02) and are in accordance with BS5480 and ASTM D3262 .

Channeline GRP two piece and multi-piece lining units come with a tapered tongue and groove longitudinal joint and a bell and spigot radial joint. Any shape or profile of the host pipe can be accommodated and short length panel units and patented jointing system allow articulation around bends. In most cases, Channeline units can be laid under normal or restricted flow conditions starting from an upstream position, eliminating the need for by-pass pumping.

Add a Step

The Add a Step modular ladder system is manufactured from FRP engineering grade plastics. The ladder is lightweight and yet still meets all the requirements of Water Services Association of Australia (WSA108).

The ladder system is completely resistant to the corrosive environment of sewerage systems that has caused many galvanised steel failures. The ladder can be purchased and installed on the same day by a semi-skilled workforce.

Benefits of Add a Step include:

• Corrosion resistant

• Lightweight but high strength

• Modular construction and ease of cutting provides DIY fabrication on site

• Multiple bracket configurations allow easy installation under various conditions
