Polystyrene Void Formers
Polystyrene Void Formers utilise the low weight/high strength characteristics of expanded
polystyrene to provide the designer and contractor with a cost effective method of reducing the
deadweight of a variety of structures:
• Motorway Bridges
• Basement Slabs
• Precast beams
• Water Treatment works
The void formers are either cylindrical, generally moulded or profiled and cut from expanded
polystyrene block. The moulded cylinders are available in diameters ranging from 250
to 1050mm and the standard length is 2.4m. By glueing and cutting the profiles can be
manufactured to suit engineers’ requirements.

Gas Barrier Systems
Proofex Total Membrane
Reinforced gas membrane designed to
protect buildings and their occupants from
the effects of methane, radon, carbon dioxide
and other harmful gases. Like conventional
ground membranes, Proofex Total also acts as
a damp-proof membrane to help protect the
building against the ingress of moisture from
the ground.
Proofex 3000MR
A high performance self adhesive membrane
for resisting methane, radon and CO, and
2
preventing water entering buildings. Proofex
3000MR also provides a vapour and waterproof
membrane to water excluding structures and
protects concrete from attack by aggressive
ground salts.
