Waterman Stop Logs manufactured from steel, stainless steel and aluminum are often used to control flows in irrigation canals, waste water and sewage treatment plants, pumping stations and power plants intakes.
A resilient seal along the bottom of each stop log seals on the sill plate or top of another stop log. Side seals are generally incorporated into the stop logs to provide for low leakage requirements.
For applications that may have flow in either direction, double seals are available.
Guides are normally embedded in the concrete, but can be designed for wall mounting with anchor bolts.
Stop Logs are placed and removed by a log lifting device and client's overhead crane or mobile crane on larger sizes. The lifting device can be operated from the deck of the structure.
Waterman of Egypt has supplied stop logs along with their guides for controlling channels of up to 15 meters deep in petrochemical and power plants in the Middle East.
