Description

Andel rainwater harvesting tanks are moulded in monolithic, high-density polyethylene (HDPE).

Monolithic HDPE body – Rotationally moulded in a single, rib-reinforced piece for maximum strength and structural integrity.

Chemical and impact resistant – HDPE offers outstanding resistance to corrosion, fuels and mechanical stress – yet remains lightweight for fast, safe handling. Far more durable and damage-resistant than traditional GRP alternatives.

Low-maintenance, cost-efficient – One-piece construction with no internal components to replace means fewer installation issues, minimal servicing, and lower lifetime costs.
