How To Install A Drainage Channel Under Your Curb Ramp
If you plan on installing a drainage channel underneath your ramp, this article will help guide you through our recommended process.
First, decide whether you want to make your ramp removable (recommended). For this, you’ll need a substrate.
What You’ll Need:
Installing a Drainage Channel
After you have cleaned the curb to remove all dirt, lay down the substrate over the top of the drainage channel to cover the curb gap from the top of the curb to the bottom of the gutter.
Note: Some rubber rolls conveniently come with adhesive backing to help keep the ramp in place.
Next, lay the drainage pipe in the middle of the curb gap, where water flows naturally. Use construction adhesive to anchor the tube to the substrate. Let it cure.
For curved driveway entrances, extra rubber membrane can be used to create a flexible tube joint. Align the pipes at the desired angle, wrap the joint using the membrane and secure it in place using duct tape. Heavy duty duct tape can also used by itself.
Mix the Curb Ramp material with about ¾ of the enclosed adhesive using a trowel or drill mixer. The granules should be *fully coated, but the mix should not be too “soupy”. Do not use the entire gallon for mixing, as a pint or so is recommended for priming.
Prime the substrate surface as well as the top and sides of the drainage channel with a thin layer of the remaining adhesive.
Spread the mixed material from the top of the curb to the bottom of the curb gutter to fill the curb gap. Shape at the desired angle to best fit your curb to achieve optimal vehicle clearance. For a smooth transition, a 25° angle can be used as a good starting point.
