Heavy Fog and Wind, No Problem! Installing Pervious Concrete on a Mountain Top

Heavy Fog and Wind, No Problem! Installing Pervious Concrete on a Mountain Top

Most of the time in Northern California we enjoy fairly mild weather and sunshine, but it's not always sunny in the Golden State. The San Francisco bay area is known for its fog. This can provide some unique installation conditions, especially when you are installing pervious concrete on the top of the highest peak of the Santa Cruz Mountains, Mount Umunhum.

Holloway Green Street - Pervious Concrete Installation

Holloway Green Street - Pervious Concrete Installation

We have finally begun to install the pervious concrete on the San Francisco Public Utilities Commission (SFPUC) Holloway Green Street Project! The project involves eight blocks of new streetscape along Holloway Street. The green street improvements include both permeable pavement and rain gardens to manage stormwater through local infiltration. One of the reasons this is such an exciting project is it's the first use of pervious concrete in a public right-of-way in San Francisco.

Pervious Concrete Meets Regulation, Lowers Project Costs, and Generates Revenue

Pervious Concrete Meets Regulation, Lowers Project Costs, and Generates Revenue

There is a new pervious parking lot in Richmond, CA. Located at the new Harbourview Apartments this parking lot is 100% pervious concrete. Parking lots are the perfect application for pervious concrete. They epitomize the principal of the Large Area Thin Infiltration Systems (LATIS).  Converting the pavement into a passive storm water detention system, that meets Provision C.3 Municipal regulations, without giving up valuable land to rain gardens, bioswales or detention ponds. By utilizing pervious concrete for the entire parking lot, this project was able to build more rentable units and achieve the most cost-effective solution, all while meeting Provision C.3 regulations.

Arroyo Mocho Trail Trys Out Some Pervious Concrete

Arroyo Mocho Trail Trys Out Some Pervious Concrete

The City of Pleasanton is trying to solve two issues they are having along their Arroyo Mocho Trail, flooding and maintenance costs. The project represents a testing site for the city to study and compare surface performance and maintenance costs of asphalt, decomposed granite and pervious concrete. Pervious concrete was specifically installed in an area that is prone to flooding. We, at BAPC, are pretty confident they will find similar results that other cities have when it comes to the high performance and low maintenance costs of pervious concrete.

Pervious Concrete Has Been Supporting Heavy Loads, Tire Abrasion and Freeze-Thaw Cycles for Years

Pervious Concrete Has Been Supporting Heavy Loads, Tire Abrasion and Freeze-Thaw Cycles for Years

Over the past few weeks we have seen the internet explode with interest over the recently announced Topmix Permeable concrete from Tarmac Lafarge in the UK. People are marveling over concrete that allows water to not only go through it, and back into the ground, but at an incredible rate. The video we featured on our last blog post is impressive and demonstrated just how fast. We were excited to see so much interest in pervious concrete by so many different people. However, we did notice some discrepancies in the way that pervious concrete was discussed in some of the media outlets, and we wanted to take some time to clarify a couple things.

Some of the media outlets portrayed pervious concrete as a new product that was not available in the United States - which is false. Pervious concrete has been used for stormwater management throughout the US for over 40 years. What's different, or innovative, about Tarmac's Topmix Permeable concrete is it boasts a whopping 35% air void space, which is why it infiltrates at such a high rate.  Tarmac representatives have stated in interviews that the product has some limitations on where, and when, it should be used. They are not recommending Topmix Permeable for high-traffic areas, in places where vehicles make lots of tight turns, or in places with freeze-thaw cycles, as it will eventually start breaking up the surface layer. Some media corespondents have portrayed that all pervious concrete had these limitations - which is also false. While Topmix Permeable may have these limitations, more traditional pervious concrete does not share the same limitations.  In the US, mix designs have evolved and have already solved the issues of heavy traffic, weight loads, turning vehicle traffic, and freeze/thaw cycles. 

Through trial and error the pervious concrete industry has discovered that 20% air void space provides the proper balance between strength, durability, and high infiltration rates. The additional bonds provided by only having 20% air voids, allows for a stronger, longer-lasting material, with just as much infiltration capacity to mitigate all of a site's stormwater.

Super Pervious Concrete - A Real Life Demonstration in Palo Alto, CA

Super Pervious Concrete - A Real Life Demonstration in Palo Alto, CA

The internet has been calling this pervious concrete "Super permeable" and Magical." If you agree, you don't have to travel to the UK to see it or have it! Bay Area Pervious Concrete has been installing super pervious concrete management systems for nearly a decade. This viral video, from  the UK firm Lafarge Tarmac, is a great representative of how fast pervious concrete can infiltrate water, but how does pervious concrete handle longer water events - like heavy rain storms? A real life test of pervious concrete. In our Stormwater Sleuthing video David compares two driveways after at least 12 hours of steady rainfall.

Why Use Asphalt? In Morgan Hill They Use Pervious Concrete Curb to Curb

Why Use Asphalt? In Morgan Hill They Use Pervious Concrete Curb to Curb

When most people think of road pavement, they think of asphalt. The new East Dunne Ave housing development in Morgan Hill, CA decided to do something different. They had Bay Area Pervious Concrete install pervious concrete from curb to curb for the new Seville Drive. Pervious concrete works great for roadways. Pervious concrete roadways have a lifespan of 30-50 years before it may need to be replaced. They are largely maintenance free for their entire lifespan. The extra benefit of pervious concrete is that it is a stormwater management system that doubles as a pavement. 

Unlike pervious concrete roads, asphalt roadways have short lifespans, and require regular maintenance. Asphalt roads must be replaced, or resealed, every 10-15 years. This increases the maintenance necessary and inconvenience for residents. Typical asphalt roads also do not provide any stormwater management services. In fact they can actually contribute to poor stormwater management by concentrating pollutants that collect on the surface and rapidly shedding them into local waterways.

Creating a Curvaceous Polished Pervious Concrete Patio

What do you do when you love to entertain in your backyard, but every time it rains your backyard gets flooded with puddles? That was the problem one of our clients was trying to solve when they discovered pervious concrete. The only problem was that many of the examples they saw online were mostly rectangular, solid color, installations - something that would not provide a unique show-piece for their backyard. They wanted something that was a talking point for their guests, a patio that stood out from the rest. Luckily, they contacted Bay Area Pervious Concrete. Working with them we developed this custom designed curvaceous patio. 

BAPC/custom-polished-pervious-concrete-patio-with-border-color

The patio was designed to flow around the backyard, to provide enough room for entertaining, while still leaving room for the owner's gardening projects. Best of all, the pervious concrete put an end to the flooding and puddling issues that sometimes put a damper their party plans.

BAPC/custom-polished-pervious-concrete-with-border-color/2

To create the visual interest that the owner desired colored borders were tooled in by our NRMCA Certified Installers and Technicians. A Polished Pervious finish was also applied to the large center section, while the colored border was left in the Classic Pervious Concrete finish. The terra cotta color was chosen for the border to compliment existing walkways along the sides of the house. We achieved this unique look using only one concrete pour, rather than the standard two pours that most borders tend to require. This allowed us to pass along some savings, in time and money, to the owners, while still achieving a hand-crafted result.
