Quantum Structured Wall Fittings
Marley Quantum was developed in 1991. The objective as to maximise the structural performance of plastic pipes and to produce a pipe that was easy to handle on site. This in turn reduces the overall installation cost.
Quantum is manufactured in two grades; sewer and highway; and offers the following benefits over traditional materials
- The flexibility to tolerate ground movement without cracking, whilst withstanding the combined effects of backfill and loading.
- Fewer joints with closer tolerances to reduce the likelihood of leakages and blockages.
- A smooth non porous bore gives good hydraulic performance.
- A high level of chemical resistance to the wide range of
substances found in both effluent and contaminated
soils.
Large diameter Quantum
- Now available in 375/400mm, 450/500mm and 600mm.
- Half slotted version available
- Meets the requirements of The Specification for Highway works, clause 501-3
