Basement Waterproofing - TrenchLock

TrenchLockis an Insert for elongated drains, often installed at the bottom of doorways or stairways, from basements to the exterior, to catch water. They are often connected to interior drains and sump pumps. They work well to let water down but also have the unintended consequence of letting air up. A perfect solution to basement environments that have drainage systems for water problems as well as radon mitigation systems.
