Brownfield Sites

Brownfield Sites

Brownfield sites gained political significance after the UK government set a national target in February 1998 to ensure 60 per cent of all new housing developments were to be built on brownfield land. This land had been previously developed for industrial or commercial purposes and may have also been contaminated owing to its prior use.

The AquaShield® Solution

AquaShield® is a non-permeable universal fitting, available as a coupling or a flange adaptor to be used on new installations and repairs to connect different barrier pipe systems reliably.

These fittings prevent contaminants entering water networks by sealing the barrier pipe from within while keeping the outer layer of the barrier pipe intact. It can also be used as a transition to a standard PE water network.

AquaShield® is rated to 16 bar working pressure and has a unique gripping mechanism offering WIS 4-24-01 type-1 end load restraint which means the pipe will fail before the fitting.

Coupling - SLA to PE

Flange Adaptor - Protecta-Line and PE connection

Flange Adaptors - Protecta-Line and PE connection

Unique Gripping Technology

AquaShield® forms a leak-tight seal without the need for a gasket simply by torquing up the bolts. The spigot profile design ensures a firm and secure connection is made from inside the pipe.

Step 1

1. Loosen bolts slightly and slide pipe on

Step 2

2. Push pipe on to spigot and check is visible in indicator window

Step 3

3. Tighten bolts sequentially and incrementally

Product Design Benefits

AquaShield® is simple to install and comes preassembled with captive and reversible stainless steel bolts, which makes it quick and easy to slide onto the pipe and tighten up with only a single spanner or a wrench. There is no requirement for pipe surface preparation and no need to wrap after installation.

Fittings have a 50 year design life expectancy and have been independently tested and approved to BS 8561:2021 and certified by WRc and RINA for permeation against contaminants as per BS 8588:2017 (section 7.7).

50 Year Lifespan
Long life Protection - 50 year design life expectancy is assured through accelerated ageing tests that simulates the life cycle of the product.

 Fully restrained, Type-1 fitting designed to meet the performance requirements of BS 8561:2021

 Universal fitting that interconnects all major barrier pipe brands including Protecta-Line, Puriton, SLA and PE 100

 Visual indicator for correct installation
