Case Studies

Our stormwater solutions are proven to solve common infrastructure and commercial issues. Our Case Studies will give you a look at a few of our many successes. 

Stormcrete® Green Corner™:
Perforated Detectable Warning

The Stormcrete® Precast Porous Concrete Green Corner™ with American Disability Act (ADA) Flow-Thru Detectable Warning Surface (DWS) has been developed to eliminate dangerous ponding / icing conditions at pedestrian ramps and corners. In addition to public safety benefits, the Stormcrete® Green Corner™ provides runoff reduction and groundwater recharge. Because the entire DWS is porous, puddles are not able to form; instead, water is directed through perforations in the surface of the DWS tile to the Stormcrete® precast porous concrete panel below.

With roughly 12,000 street corners to manage across its five Boroughs, the New York City Department of Transportation (DOT) has the daunting task of assuring pedestrian safety while meeting the updated standards adopted by the Americans with Disability Act (ADA). The DOT ultimately settled on testing the Stormcrete® modular porous concrete stormwater system. To assess the usefulness of the Stormcrete® Green Corner™ the DOT selected a bus stop on the corner of Linden Blvd & 204th St in Queens as a test location (see photos).

Stormcrete® Alley: First Green Alley in Lowell, MA

In 2014, the Lowell Regional Waste Water Utility (LRWWU) began a plan to separate a combined storm and sanitary sewer in the area surrounding Decatur Way, an alley in inner-city Lowell, MA. During a rapid, three month design period, various options were considered for the pervious pavement, but were rejected due to concerns about either poor quality control during placement or maintenance concerns. The engineering design firm, CDM Smith identified Stormcrete® Modular Precast Porous Concrete Paving Slabs as a viable alternative and worked with the support staff at PT,LLC to prepare details and specifications for the project. A Stormcrete® System was successfully installed at the project and is now allowing stormwater that falls in the area to infiltrate into the surrounding area instead of flowing to the sanitary sewer.

Stormecrete® Parking: CASC Engineering LID/GI Demonstration Site In Orange County, CA

CASC Engineering, a successful and growing consultancy had a need to increase their parking area but wanted to do so with minimal environmental impact. They approached Porous Technologies, LLC for design help in choosing the appropriate surface material that would allow the stormwater to infiltrate where it falls. Porous Technologies, LLC assisted CASC engineers in preparing a site design for the project and Stormcrete® Precast Porous Concrete Panels were installed in three parking lot spaces located in the central portion of CASC’s parking lot. An informational sign was included as part of the project to let visitors know about the system and its benefits.

Stormcrete® Gutter: Ventura County Completed Retrofit For Groundwater Recharge Project

This residential area in Ventura County was subjected to frequent on-street flooding events because there is no piped underground drainage system present there. So instead of installing a new, costly, conventional piped storm drainage system, the County engineers opted for a porous pavement system which allows stormwater to infiltrate naturally back into the surrounding soils. Stormcrete® Panels were installed in over 5,000 lineal feet of gutters to provide infiltration at its source and to prevent flooding.
