Bringing the Outdoors In

A challenging indoor waterfall project

Our customer, Tyler, wanted an indoor waterfall and lots of plants in the atrium of his 39-unit apartment building in downtown Ellensburg, Washington. This was a challenging project due to the location; the atrium was directly over a basement parking garage for the apartment complex.

We’re on it, Tyler! With lush plantings, potted trees throughout, lots of lighting, a misting system, streetlamps and comfortable seating, we knew this was going to be a good one.

The enclosure’s interior was completely lined with spray-on polyurea by Zuber Polymers.

First, we applied spray-on polyurea throughout the enclosure, with drainage to the parking garage below. (That part wasn’t really on the “menu,” but Aquascape techniques were employed throughout.) The enclosure’s interior was completely lined with spray-on polyurea by Zuber Polymers as a secondary catchment safety factor in the event of a leak. A floor drain was led to the parking garage below the installation.

We located the reservoir of the pondless installation over the truss underneath and used styrofoam as “dirt” to lighten the load as well as “Featherstone” (pumice) for the rock in the feature. The gravel we used was volcanic beach lava from Coverall stone.

Aquatic plants were provided by Endless Song Watergardens, and terrestrial plants and pots were supplied by Beaver Bark Gift and Garden Center.
