How heavy of a load can Grasscrete support?
Grasscrete is a pervious reinforced concrete structure for all types of trafficked areas that is either covered with grass, has grass growing in the voids of the structure or has stone in the voids of the structure.

How much traffic can the product withstand?
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.

Can Grasscrete be used for emergency access such as fire lanes?
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.

What is the installed cost for Grasscrete vs. concrete?
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.

What is the installed cost for Grasscrete vs. other pervious grass 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.

Can we plow Grasscrete?
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.

Can we use Grasscrete in lieu of a pervious concrete parking lot?
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.

Additionally Grasscrete is not subject to clogging issues and in the event that too much silt has entered the voids, they can be mechanically cleaned in an efficient manner unlike traditional pervious concrete.
