Percoa Pavers installed in the Rain

One of the benefits of Precast Percoa pervious pavers, they can be installed even if it’s raining.

It’s a worn-out phrase to say that ‘water is the lifeblood of the state,’ but it is worn out because it is true.”

Although the above words were spoken in the early 1990s by then-Nebraska Governor Ben Nelson, they are still very true today.

Water is vital to Nebraska.  In fact, groundwater provides approximately 85 percent of the water used for human consumption in Nebraska.

With approximately half of the state’s cropland under irrigation (see brief history of irrigation in Nebraska), agriculture, by far, is the leading consumer of water.”

Freeze – Thaw

We always are asked about freeze – thaw in our product.
Because of the void structure and the way we manufacture Percoa Slabs they work well in places where temps can drop to below 0. Just last week we hit -12 with the wind-chill putting us at -30.
This picture shows Percoa Slabs on the right and failing poured in place pervious concrete on the left.

Using Pervious Concrete to Achieve LEED Points

As appeared in Concrete InFocus, a publication of NRMCA, Winter 2008

“Pervious concrete is a unique and innovative means to manage stormwater. When pervious concrete is used in building site design, it can aid in the process of qualifying for LEED Green Building Rating System credits.”

“Pervious pavements function like storm water retention basins and allows the stormwater to infiltrate the soil over a large area, thus facilitating recharge of precious groundwater supplies.

Pervious concrete has been used successfully in many types of construction on applications such as parking lots, streets, plazas, nature trails, and walkways. While pervious concrete can be used for a surprising number of applications, its primary use is in pavement. Pervious concrete is a performance-engineered concrete made with controlled amounts of aggregates, water and cementitious materials to create a mass of aggregate particles cover with a thin coating of paste. A pervious concrete mixture contains little or no sand, creating a substantial void content. Using sufficient paste to coat and bind the aggregate particles together creates a system of highly permeable, interconnected voids that drains quickly. Typically, between 15% and 25% voids are achieved in the hardened concrete, and flow rates for water through pervious concrete are typically around 480 in./hr (0.34 cm/s), although they can be much higher. Both the low mortar content and high porosity also reduce strength compared to conventional concrete mixtures, but sufficient strength for many applications is readily achieved.”

Snow on Percoa

“Why use Percoa?”

According to the U.S. Environmental Protection Agency (EPA), about 90 percent of surface pollutants are carried by the first 1-1/2 inch of rainfall.

Storm water drains don’t typically channel this polluted runoff to treatment facilities, but instead convey it directly into local water bodies. Polluted runoff, if not diverted, ends up in our waterways along with water that is heated as it flows over paved surfaces and into the watershed. The concern being that temperature change in a stream or lake can harm aquatic plants and wildlife.

The use of pervious concrete (Percoa Slabs)is a widely accepted as an effective material to capture, filter and disperse storm water runoff and is among the Best Management Practices (“BMPs”) recommended by the EPA as well as by other agencies

Percoa’s proprietary, patented products can be used for new construction or to retro-fit existing concrete or asphalt surfaces such as storm water runoff basins, parking lots, driveways, walkways, patios, and a myriad of other surface applications where water runoff is a concern. Percoa combats the harmful effects of pollution entering the water supply, and helps reduce temperature changes.
