Why Should I Extend My Downspouts Underground?

Surface downspout extensions can be a tripping hazard, get in the way of mowing, and often just move water a few feet from your foundation. An underground extension carries that water completely away from your home and releases it at a safe discharge point, protecting your foundation and keeping your yard looking clean and hazard free.

Where Does the Water Go When It Exits the Underground Pipe?

The water is directed to a pop-up emitter with a turf guard that prevents overgrowth from blocking the emitter.

Will the Underground Pipe Get Clogged?

It can over time if not properly installed. Keeping proper slope, and installing our leaf guard at the downspout connection all significantly reduce the chance of clogging. Paired with our catch basins that collect 5 years of shingle gravel before having to be cleaned.

Underground Downspout Drain Install

Above ground downspout extensions are ugly, create tripping hazards, and are easily damaged. Uncontrolled roof runoff can lead to water damage.

When we install an underground downspout drain we take everything into consideration like slope of the ground whether we need to add more slope or not and planning the most effective route to drain the water saftley away.

Then we start trenching to fit the corrugated pipe in and start attatching the catch basin and pop up emitter to give the water a place to leave.
