Both Drain Guard models use a needlepunched, geotextile that is ludicrously strong, filters out sand, sediment, trash, debris and other junk… AND it absorbs oil. Cool huh? But wait! There’s more! The Oil & Sediment Plus Model adds a material called Ultra-X-Tex which allows it to absorb even MORE oil (thus the “plus”).
The units are designed with overflow ports so in the event of a large amount of rainfall in a short period of time, or if the Drain Guard is not properly maintained and becomes full of dirt, sand and sediment, the water can flow through the overflow ports preventing any flooding or ponding at street level.
Ok, your mind is in the gutter now. Please try and keep it there. See ya next week!
