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 rubber substrate. We recommend a neoprene rubber sheet like this one or PVC shower pan liner like this one.
What You’ll Need:
Note: Tubing is available in different sizes as well as in aluminum or PVC; choose at your discretion. The height of the tube should be proportional to your curb gap. Allow for a minimum of 2″ space above the tube for the Curb Ramp compound. Any less could compromise the structural integrity of the ramp.
Installing a Drainage Channel
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.
Tip: The shipping package can be used to mix. Put newspaper or other disposable material beneath the box to protect against accidental spillage.
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.
