Stormwater management
Stormwater collectors and drainage networks: GRP, HDPE, steel-cylinder reinforced concrete and GRP shells.
Collecting stormwater
Stormwater collectors can be built in centrifugally cast GRP, HDPE, steel-cylinder reinforced concrete or, for rehabilitation, GRP shells.
- Centrifugally cast GRP: ideal for large flows and hydraulic variations
- HDPE: stormwater networks
- Steel-cylinder reinforced concrete: collectors, drainage networks and structures under heavy loads
- GRP shells: stormwater pipes and culverts, for rehabilitation or new structures
The right solutions
The ranges we most often propose for this application.
Centrifugally cast GRP
Pipes from DN 200 to 2000 for sewerage, stormwater and raw water.
Discover
GRP shells
Rehabilitation and sliplining of existing structures, custom shapes.
Discover
HDPE pipes
Water, sewerage, irrigation, industry: PE100 pipes and double-wall corrugated pipes.
Discover
Steel-cylinder reinforced concrete
DN 1000 to 2500: drinking-water transfer, stormwater, sewerage and buried structures.
DiscoverWhat our support changes
Choice of material
GRP, HDPE or other: we compare based on diameter, depth and soil.
Hydraulic and mechanical calculations
Flow capacity, ring stiffness, buoyancy: we check the sensitive points.
Installation advice
Bedding, backfill, compaction and checks to plan for on site.
Frequently asked questions
Which pipes for a stormwater collector?
Centrifugally cast GRP (ideal for high flows), HDPE, steel-cylinder reinforced concrete (DN 1000 to 2500) or GRP shells for rehabilitation. We compare the options with you.
