Polyduct — Pre-Formed Ducting
Moulded MDPE Polyduct — seamless, inherently round, double-ringed cylinders and pre-formed fittings (oblique, trouser-Y, intake non-return valves, corkscrew). Standard diameters 1065 / 1200 / 1400 mm; non-standard fabricated to order.
Polyduct — Segmented Ducting
Large-bore segmented Polyduct — split-cylinder construction for diameters that exceed road-transport limits (Ø2.4 m, Ø2800 mm, 3 m ID), plus modular intake cones and stacked artificial-shaft configurations. Assembled on site, no oversized permits.

Donut Pump Floats
Highly customisable HDPE Donut pump floats to suit pumps 5 kW – 90 kW +. Float maintains pump height plus only 20 mm versus ≈ 600 mm for underside-bolt designs. One float fits 5 different pump sizes (5 / 8 / 18 / 20 / 37 kW) with insert rings supplied.
Floating Platforms
HDPE floating platforms — modular work platforms and barges from 4.7 m modular pontoons to 21 m HDPE barges. Workboat-class flotation: corrosion-free, scalable, road-transport-ready and easy to reconfigure on site.
View product
Pontoons
HDPE pontoons — sealed-cylinder flotation modules engineered for project-specific installations. Built to drawing for shore-tied pontoon barges, modular work platforms and bespoke marine builds.
View product
Floating Intake Screens
Floating intake screens — self-contained and self-buoyant. Enables floating intakes instead of fixed structures, eliminating the special-design and leg-support work that fixed installs require.
