"Environmental products help protect and sustain our resources"

Environmental issues place increasing responsibility on engineers to ensure that hazardous products are handled safely. Closer focus on health and safety at work issues has also meant that companies have greater responsibilities to maintain a secure environment for employees.

Double containment piping is by no means a new concept to process piping applications. Systems using a carrier pipe with secondary containment have been installed using metal pipes for many years.

DuoSafe® PVC-U and PVC-C double containment systems are designed for ease of installation.

DuoSafe® FLEX is manufactured for dosing applications.

Poly-Flo is a unique system using specially extruded twin-wall pipes and injection moulded twin-wall fittings.

AGRUSAFE double containment is a fabricated system produced in a wide range of sizes and in a variety of material combinations.

Aliaxis P-LX fuel systems are designed to safely convey petrol, diesel and fuel oil in below ground applications while ensuring harmful emissions cannot escape into the environment.

AGRUSAFE Sure Grip® Liners can be used to form single or twin-wall linings for concrete structures and tanks.
