About Us

The VSS® wall, (vegetative sound structures), was conceived by principles of Cascade Concrete Industries Inc. while manufacturing various types of sound barrier walls for both State and private use. Conceptually the VSS® concept was discussed with University of British Columbia (UBC) professors, their students, and colleagues. The interest from these experts who research sound engineering was strong and unanimous. From there the concept was shared with the Horticultural department at UBC and the British Columbia Ministry of Transportation, (MOT).

MOT responded by offering a substantial grant for research studies, testing, and preparing reports on all aspects of VSS®. This work took place over two years at UBC and included full size test walls constructed and tested both in anechoic chambers off site and at UBC’s campus. The detailed results were published together with other studies of certain aspects tested on UBC’s work. UBC, has a continuing financial interest in the development, and use of VSS® walls.

Cascade Concrete Industries

We use state of the art and highly efficient dry cast machinery. Cascade Concrete Industries is able to produce the building blocks for the VSS® wall system using less cement and more manufacturing by-products than traditional casting processes. This keeps greenhouse gasses and waste products out of our landfills and environment.


Rick Peterson is a serial entrepreneur and local Seattle area investor and developer for the past 40 years. He has owned Cascade Concrete Industries for 22 years. He started VSS® in 2012 to build a better looking, more environmentally friendly sound reducing wall. Bill Rucker has an extensive background in commercial real estate and technical sales. He joined the VSS®/Cascade family in 2013 and is excited about transforming ugly concrete barrier walls into lush pollution eating landscapes.


Just one month after planting, the highly drought tolerant Kurapia has nearly covered all of the exposed wall surfaces.

After one month, the drought tolerant sedums are rapidly filling in and the grasses on top are well established.

Foreground, after two months, drought tolerant sedum tiles are changing color with the seasons and the base plants are preventing any weeds from growing near the wall.
