gratesump Grate SumpThe GrateSump™ is an integral component of your new basement water control system.

The GrateSump has several key features that ensure unmatched performance and reliability like no other in the basement waterproofing industry. As part of the Grate Drain System, it will work seamlessly to protect your pump and remove the water from the drain and under your basement floor.

Performance & Reliability

Benefits Include:

  • Does not promote undermining of the foundation. Traditional sump liners can remove sediment from under the basement footing causing the foundation to weaken.
  • GrateSump resists iron and clogging. With large engineered slots on the front two sides of the GrateSump reduces clogging and increases water flow.
  • Built in pump stand. Built in pump stand keeps debris away from pump and aids in cleaning.
  • Dehumidifier drain plug. Connect your dehumidifier to the built-in drain plug.
  • GrateSump dual combination. GrateSumps can be linked together to add an additional back up pumping system.
  • Virtually airtight cover. The impressive steel-gray plastic cover reduces ground humidity from entering basement.

Grate Sumps are standard in all of our basement waterproofing solutions when a sump pump is required. They can also be installed in a crawl space waterproofing design as well
