Trench drains

Sigma's new Hydrotec trench drains offer significant advantages over previous generations of drainage channels. The drains offer more durability, simpler installation and a patented locking mechanism that simplifies cleaning and maintenance. Comprised of fiber-reinforced concrete, they are more durable than polymer concrete. The drains also respond to changes in temperature and moisture the same way that their surroundings do, so they are considered a lower risk for environmental structural damage.
