Aliaxis unveils new next generation Boundary Box

  • 31 Mar 2023

Fluid management solutions provider Aliaxis enhances its Protecta-Line barrier system offering with the introduction of the new Protecta-Line Boundary Box. This is the only completely plastic boundary box fully approved for contaminated land usage. 

With homes increasingly being built on brownfield sites that may contain substances harmful to people, it is vital to provide drinking water in a safe and efficient way and avoid the potential danger of exposure to significant surface waters or ground water pollution. 

Boundary boxes are designed to house the meter at the boundary between the water main and the domestic supply and this new Protecta-Line solution not only provides a shield against all known contaminants, but it’s the only ‘Grade B’ load bearing height adjustable boundary box on the market. It is available with a standard lid, as well as three further lid choices: slope, square cowl and fixed.


The Protecta-Line range is the market leading and original barrier pipe system for the safe transportation of drinking water through areas of contaminated land, or for sites with future potential contamination concerns. The multi-layer construction of the range consists of an internal polyethylene core for carrying clean water, an aluminium barrier layer and an outer polyethylene layer for protection.    

‘Total piece of mind’

Richard Pedley, Segment Manager for Infrastructure Networks at Aliaxis, comments: “The Protecta Line Boundary Box features our next generation of manifold which interfaces with Protecta-Line pipe tails, offering end connection flexibility that can be easily joined to our Protecta-Line system using the means of dedicated barrier compression fittings. 

“It brings together our trusted and high performance Protecta-Line technology with the acknowledged strength and versatility of our Adjusta range to provide a complete water supply solution in contaminated land applications, all from one solution provider, delivering total peace of mind for installers and asset owners alike.”

The wider Protecta-line range will safely transport drinking water through areas of contaminated land. Contaminants that can be present include substances such as oils and tars, heavy metals, fuels and chemical substances.

Available in pipe sizes from 25mm up to 630mm, the Protecta-line portfolio includes a diverse range of BS 8588 approved fittings for different jointing methods including electrofusion and mechanical, providing customers with the right solution to meet their individual requirements.

Aliaxis will be showcasing this groundbreaking solution for the first time at Utility Week Live (Stand J16) at the NEC in Birmingham, from 16 – 17 May).
