Flood Protection and Watercourse Regulation Solutions
Manhole covers
A toad lid (backflow flap valve) consists of a conical octagonal housing, a flat lid, a shaft around which the flap rotates, and a watertight seal located on both sides of the housing.
If needed, the cover can be additionally weighted with a ballast. The honeycomb profile is made of UV-stabilized high-density polyethylene (HDPE) and reinforced with hot-dip galvanized steel profiles.
- Low weight and easy installation
- The construction is designed for mounting on flat walls or flanges
- Non-return (check) flap valves are manufactured for openings from DN 250 to DN 1,500
Stoplog flood barriers
Sheet-type stoplogs for installation on straight walls are manufactured and supplied in sizes ranging from DN 250 mm to DN 1500 mm.
The choice of materials ensures long-lasting, reliable performance without special maintenance costs.
All steel components are protected by hot-dip galvanizing, and all plastic parts are UV-stabilized, ensuring a long service life.
The flap actuation system enables smooth, easy movement of the flap within the sluice body without the possibility of detachment. The conical design of the housing and flap ensures complete sealing of the sluice.
The structural design of the stoplog barrier enables modular installation in segments, adapted for manual on-site assembly without the use of heavy machinery.
Mobile flood barriers
We have developed our own system of mobile flood protection barriers designed to safeguard urban areas from extremely high water levels that threaten populated communities.
The system is characterized by a selection of lightweight and durable materials, as well as an exceptionally simple installation on prepared terrain for barrier placement.
The barrier system elements are designed to take up very little storage space when they are not in use.
Site preparation itself does not require extensive work—and therefore does not involve high costs—while also preserving the functionality and aesthetics of the site/area during periods when there is no need for flood protection against high water levels.
There is an option to deploy the barriers on unprepared terrain, such as embankment crests, replacing standard sandbag flood-defense methods. This significantly reduces time and costs and increases the overall safety level of flood protection.
The barriers are recommended for raising a flood-defense line up to 1.5 meters in height.
