Nestled across the bay, the 21st Century Hayward Library is marking great strides towards completion. Bay Area Pervious Concrete has been working on this particular project for some months now. As our work nears it’s end, the finishing touches for landscaping are being added. All in all, the new library is a beautiful public space that residents will soon be able to enjoy! Designed with winding pedestrian pathways showcasing our fine-grain polished finish infused with warm earth tones, this new library is nothing short of a modern marvel.

Running out of room at their current location, the South San Francisco Scavenger Company recently purchased a large property to store their debris boxes and garbage bins. The 66,000 square foot yard, however, was a combination of dirt and gravel, and not at all suitable for their needs. The initial plan was to pave the yard with asphalt, until the City informed them they could not do anything that would increase the quantity of stormwater-runoff from the property.

Bay Area Pervious Concrete was recently asked to install our decorative exposed aggregate pervious pavement in the parking areas of a high-end residential project. The driveway itself was a beautiful 2’ x 2’ Italian stone and was designed to be permeable. To achieve this, the landscape contractor used a Class II permeable base and then mortared directly on the base to set the stones. The bed of mortar was carefully placed so as not to fill the spaces between the stone, creating a passageway for surface water to pass through to the base rock.

“One of these things is not like the other,” Ernie from Sesame Street said it best. For those that claim impervious surfaces, such as asphalt and concrete, and pervious surfaces are synonymous, that is not true. Bay Area Pervious Concrete’s David Liguori went out on the field this week to report on some real-time comparisons between these two surfaces during our most recent storm, and the evidence is striking.

Mr. Liguori has returned!
With the first heavy rainfall of the year, David was quick to grab his coat to report out on the field to bring you another episode in our Stormwater Sleuthing series. This episode features the highly effective performance of pervious concrete in a parking lot during a two-day torrential rainstorm. The project was installed about a year ago at Golden Hill Cemetery in Colma, CA and is still working as intended. As they say in the pervious concrete industry, when it rains, it drains!

And nothing speaks louder than Bay Area Pervious Concrete’s first multi-layer decorative installation with radiant heating at a massive residential project in Lake Tahoe. The project began this summer after two years of cross-collaboration between the architect, engineer, general contractor, and Bay Area Pervious Concrete.

Want to know how much base rock you need under your pervious concrete pavement? We've done all the calculations for you! Designed with low infiltration soils, like Class C & D, in mind these design tables allow you to quickly size the infiltration bed underneath your pervious concrete. Tables feature calculations for infiltration rates as low as 0.025 inches per hour!

Back in 2013 Bay Area Pervious Concrete was hired to install some BAPC Polished Pervious Concrete™ on the newly expanded campus of White Hill Middle School in Fairfax, CA. The project's site designs were done by our friends at Sherwood Engineers. Recently, a group of Sherwood Engineers project managers took a tour of the school to review how the site improvements fared after five years of use. They were kind enough to share some photos with us.

Over the several years BAPC's David Liguori has worked with Caltrans to update their pervious concrete design guidelines and specifications. Recently, he and the California Nevada Cement Association were asked by Caltrans District 4 to provide a pervious concrete workshop for their material, pavement, stormwater, and highway engineers.
The three hour workshop provided 28 Caltrans engineers with the latest developments in pervious concrete system design, specifications, and best management practices. Afterwards attendees were bursting with ideas and projects where pervious concrete would help solve their stormwater design issues. They expressed how grateful they were that our presentation was technical, detail-oriented and highly educational, not just a fluffy sales-pitch.
