Rocko Ø1800 in detail.
The tank is made from high-quality polyethylene (PE) in a single piece, resulting in a completely waterproof and durable construction. The wall thickness of 8–14 mm and integrated reinforcing ribs ensure maximum stability in the ground.
The tank can be installed both underground and above ground.
- PE LID WITH ADAPTER (INCLUDED IN THE BASIC PACKAGE)
- The lid, with its gasket and hinged closure, ensures effective watertightness. The PE lid (DN 600) has a load-bearing capacity of up to 200 kg.
- CONNECTION OPTIONS
- ANCHOR HOLES
- They make it easier to secure the tank to a concrete slab when anchoring is required due to a high water table.
- REINFORCING RIBs
- Reinforcing ribs on both sides ensure the tank's stability and provide protection when the water table is high.
- PE RING
- The PE ring allows for easy installation of an additional fuel tank extension, making it easy to adapt to the terrain.
