Why TrenchDrain™ can help keep your home dry

grated drain system

The TrenchDrain™ is the ideal solution for leaks around doorways and garages in any home.

TrenchDrain™ is specifically designed to intercept water at doorways and similar openings and direct it to your sump pump. This system resembles half of a piping system with a grate fitted snugly on top. The grate is flush with or slightly below the floor, where it can catch water entering from the outside.

Advantages to our system:

  • Grated openings collect flooding water
  • Removable lid for cleaning & service
  • Designed to create no tripping hazards
  • Compatible with our other drain systems
  • Effective for hatchways, entry doors, garage doors, and more
  • Includes a written lifetime warranty
