We supply 100% sealed sedimentation systems for roads and railways. Our sedimentation tanks help you meet today's environmental requirements for the treatment of wash water, sand and stone.

Durability with KRAHTM technology

Haplast sedimentation tanks are made of PE based on KRAHTM technology. The tanks have double walls that provide good insulation properties when sufficiently buried. This is a flexible and strong solution that also allows local soil to be used as backfill when the installation instructions are followed. Smooth and bright interior surfaces simplify cleaning and inspection.

100% leakage free

Fully welded joints and pipe penetrations ensure 100% watertight solutions. The tanks prevent both leakage and inflow of stormwater. We also install sealed, insulated lids on our tanks.

Complete solutions

The tanks can be made with an inner diameter of up to 3000 mm. They can be delivered as pre-assembled, complete solutions or in modules up to 24 meters, limited only by the permitted transport length. If longer tanks are required, we can supply modules up to 24 meters that are welded together at the construction site.

Quick installation - long lifespan

The tanks come with pre-assembled pumps and valves, so all that's left to do once the tank is in place is to connect pipe and power. Plug-and-play solutions and low tare weight streamline both transportation time and construction time at the site. At the same time, our PE tanks have a long lifespan (100 years+) and are a lasting solution for your project.
