Product Specs and Installation Guidelines
Overview
GrateSump is an engineered sump pump housing that is designed to quickly remove water from under a basement floor without undermining the soil from under the foundation walls.
The GrateSump was designed not only for the installer, but especially for the service technician. It has a solid cover that is easy to take off and easy to put on. There is a built in pump stand, large grated holes on two sides and solid walls on the two sides that face the foundation. All GrateSump liners come with a permanent mesh filter which can be cleaned from within the sump housing. GrateSumps can be joined together with a GrateSump Joiner, this allows on GrateSump to be a primary and a second one can be used to house a battery back up pump.

Break out or saw cut concrete slab approximately 2ft x 2ft square and dig down at least 22 inches. Place 2-3 inches of clean crushed stone. (If sand soils are present it is recommended to place a 2 ft square of Filter Mat (FM) before placing the crushed stone to keep the sand from coming up into the GrateSump). Place the Permanent Mesh Filter around the GrateSump so that it covers the large holes.
Place the GrateSump so the solid walls face toward the foundation walls and the openings face in so as to collect ground water from under the basement floor. Surround the GrateSump with 3/4" - 1" crushed stone or river stone up to within 2 inches of the top of the GrateSump. Re-concrete with at least 1 1/2" of 3000-4000 lb concrete or sand mix. *NOTE: Never surround the GrateSump with any
fabric type filter use only the Permanent Mesh Filter. Each GrateSump should house one pump except for our Grate Sump Z which is a job ready pre-assembled primary and secondary battery back up pump all in one GrateSump housing.
