Grasscrete is commonly used as a pervious concrete parking lot where as the voids are simply filled with stone rather than grass. Unlike no-fines pervious concrete Grasscrete is easily reinforced, the reinforcing steel is not subject to corrosion due to the no fines mix of traditional pervious concrete, the mix designs are established freeze-thaw resistant, the final surface is exceedingly more abrasion resistant that pervious concrete mixes, and there is no issue with rock pop outs.nnAdditionally Grasscrete is not subject … Read more
Applications requiring plowing are typically applications requiring continuous vehicle use and therefore are void grassed only installations. Grasscrete installed in this manner can be plowed with conventional equipment requiring no specialized attachments or care compared to other less robust systems.
Grasscrete is generally slightly more than other pervious grassed systems such as plastic rings, plastic unit pavers and pre-cast unit pavers. However, using Grasscrete means you are using the most robust system with the lowest lifecycle costs of any pervious system with comparable capacity, durability and performance.
Grasscrete is generally 30% higher than traditional concrete pavement. Using Grasscrete can eliminate or minimize the need for storm water collection systems which may be a substantial savings.
Grasscrete can be designed and installed to support any vehicle. The standard minimum installation supports vehicles weighing 75,000 pounds with more customized installations capable of supporting vehicles exceeding 150,000 pounds – including tracked vehicles.
Fully grassed installations can handle periodic traffic such as maintenance access or overflow parking. This is dictated by the robustness of the grass itself. Void grassed only installations can be driven on continuously with no issues associated with plowing, high speed travel or tires turning at particular places in the installation.
Yes, this is one of the more common uses for Grasscrete. As an example, the City of Los Angeles Fire Department has been using Grasscrete exclusively since 1982.
Yes. For all the reasons listed above.
Yes. Grasscrete is ideal for use as a retaining pond bottom as it is pervious which helps avoid liability issues associated with using non-pervious concrete for retaining pond bottoms. It can also be mechanically scraped which allows for sediment to be excavated periodically using large pieces of equipment while maintaining the root structure of the grass which repopulates to conceal the system to provide a food source and cover for local animal species.
Yes. Concealed and Partially Concealed Grasscrete drains comparatively to local grassed areas with similar soils. Stone Filled installations have virtually zero runoff even in a exceptional rain event provided that there is adequate capacity to contain the water beneath the Grasscrete.
