Timber Stop Logs

Timber stop logs and stop log panels are an essential solution for controlling water levels and flow in floodgates, dams, hatcheries, canals, spillways, and water management systems. By stacking stop logs within guide channels, operators can quickly raise or lower water levels, or completely de-water conduits and waterways for inspection, repair, and maintenance.

We manufacture high-quality timber stop logs engineered for strength, durability, and reliable water control. Our products are used across hydroelectric facilities, municipal water systems, fisheries, and infrastructure projects throughout Canada and the USA.
