– The combined flexibility to tolerate ground movement without damage, whilst withstanding the combined effects of backfill and loading
– Fewer joints to reduce the likelihood of leaks & blockages
– A high level of chemical resistance to the wide range of substances found in both effluent & contaminated soils
– A smooth bore gives good hydraulic performance
– WIS 4-35-01/BSEN13476-3 certification for adoptable foul and surface water sewers
