Multifunctional gullies with a width of 100, 150, 200, 300 and 400mm, which you can find in our offer, are designed for point drainage of roads, streets, parking lots, maneuvering yards, etc.

AS products are of the highest quality.
The body of the manholes is made of polymer-cement concrete in the C55/67 class and reinforced with alkali-resistant glass fiber, which improves the bending properties and impact strength of concrete.
The frames are made of hot-rolled, hot-dip galvanized profiles, anchored in the walls of the drainage body, significantly improving the strength parameters in relation to cast iron strips and other strips made of, for example, thin cold-formed sheets.

The grates are made of nodular cast iron, class B125 kN to F900 kN and are screwed with high-strength stainless steel bolts.

Our manholes have water drainage holes equipped with PVC sockets with gaskets in the side walls or the bottom.
The wells can be designed as outflow or sedimentation wells and can be additionally equipped with a dirt trap.

The advantage of the system is the resistance of concrete to long-term effects of frost and defrosting salts ("+ R") in accordance with PN-EN 1433 and the chemical resistance of concrete, including oil derivatives, in accordance with PN-EN 858-1: 2005.
