Question DetailsAsked on 8/4/2016

where can I buy Grate Drain basement waterproofing products without a contractor?

I want to install a basement sump system my self. I looked at the Grate Drain system and think it would be the best system for me. I want to install it my self but cant find where to buy the system without hiring a contractor.

Do you have the same question? Follow this Question

Per their website, they only sell to contractors - a gimmick to make their product seem more exclusive, in my opinion, because having gone through their website (I had never heard of this brand) I see nothing special or beneficially unique about their products. I do find their advertising and videos a bit on the misleading side, plus they push a lot of "features" as if they were unique but are standard with almost all such systems - like being able to slope the piping so water does not go stagnant in them, which is a standard best practice in underfloor drain systems.

I see nothing to recommend their product over established brandnames and standard perforated plastic drain pipe with proper filtration media.

You can find a lot of previous questions and comments about foundation/basement drain systems in the Home > Basement Waterproofing link in Browse Projects, at lower left.

One recommendation not specifically related to their system - NEVER fall for a residential system (or in all but unusual cases a commercial building system) that calls for punching through the foundation to drain outside water into a basement drain system - it just makes absolutely zero sense to intentionally drain outside water into your basement to get rid of it. NOt only does that likely create MORE wter problems with damp slab and so forth, but you cannot control the inflow once you have done that - I have seen such systems flowing over 30 gpm of groundwater (far beyond the capacity of the sump pump) because of this mistake, including one basement about 6 feet deep in water because the sump pump could not keep up. If you have an outside-of-foundation water problem, solve it there - with surface diversion away from the foundation, roof downspout control, exterior foundation waterproofing and french drains leading away from the house, or in topographically constrained situations foundation waterproofing and a french drain system with wetwell and outdoor sump pump to remove the water.

I would also recommend against above-slab systems - a ground-out or cast depression around the perimeter of unfinished basements can work for occasional infiltration in rare very heavy rains, but for any sort of recurring infiltration issue I recommend solving it right with a sub-slab system installed below bottom of footer or lower - that is below BOTTOM of footer (though not right next to it to avoid removing lateral support to the footer), not bottom of SLAB. See this previous question on that issue -
