Sustainable Paving Systems Q and A with the Experts

A Conversation with Terry Grimble - Director of Technical Services, Sustainable Paving Systems and Grasscrete Cast-In-Place Pervious Concrete
by Staff

What makes Sustainable Paving Systems and Grasscrete the top choice for Landscape Architects?

Grasscrete has been installed in the United States since 1975, establishing itself as a reliable product with a proven track record spanning decades of successful installations across various demanding applications. Sustainable Paving Systems (SPS) specifically emphasizes pervious concrete pavements, making it the most experienced representative for specifiers seeking continuously reinforced, structural concrete paving products.

What makes Sustainable Paving Systems and Grasscrete unique?

One of the key advantages of Grasscrete is its exceptional load-bearing capacity. Unlike pervious plastic or pre-cast unit pavers, Grasscrete is made from reinforced cast in place concrete. This structural composition enables it to distribute loads over a significantly larger area, allowing it to accommodate much heavier vehicles compared to other pervious systems available on the marketplace. Grasscrete is constructed using the same high-strength concrete commonly used for parking lots and roads, making it suitable for continuous traffic-bearing applications. In contrast, many other pervious paving products are not designed to withstand daily traffic from vehicles such as trash trucks, buses, delivery vehicles, and other commercial traffic.

Why would Landscape Architects choose Grasscrete over your competitors?

Grasscrete, a product manufactured in the United States, incorporates a biodegradable form made from wood and paper waste sources to achieve its distinctive cellular pattern. In addition, all the materials needed for the construction of Grasscrete, except for the forms, are locally sourced. This localized sourcing minimizes the need for extensive shipping compared to conventional plastic systems, which are predominantly manufactured overseas using carbon-intensive raw materials and energy sources. By reducing transportation and utilizing locally available materials, Grasscrete demonstrates a commitment to sustainability and a reduced carbon footprint.

Can you tell me about the different project types Grasscrete can be applied in?

Grasscrete offers versatility and can be effectively utilized in a wide range of applications, including parking lots, slope protection, emergency vehicle access, low impact access roads, retention pond bottoms, and as scour points for bridges and dams. Its durable and robust nature makes it an ideal choice for any project that necessitates a resilient pervious pavement solution. With its ability to withstand varying environmental conditions and heavy usage, Grasscrete provides a reliable and long-lasting surfacing option for a diverse array of projects.

Can Grasscrete be applied to all climates throughout the country?

Grasscrete has a proven track record of successful installations in diverse climate types worldwide. Sustainable Paving Systems, as a trusted provider, has been supplying biodegradable forms for constructing Grasscrete in the United States and Canada for several decades.

Is Grasscrete customizable? If so, can you tell me about the possibilities?

Grasscrete offers the flexibility to be used as a fully concealed system, seamlessly blending into the surrounding environment by incorporating grass, ground cover mulch, or other suitable material on top. Alternatively, it can be utilized with only the voids filled for applications with higher traffic frequency, such as parking lots or access roads. In sloped applications that require heavy vehicle access, the void-filled system can be employed to ensure continuous tire contact and excellent traction on the concrete surface. Moreover, many applications opt to fill the voids with stone, creating a completely pervious surface that requires no irrigation or
extensive maintenance.

Are there any trends you are seeing in what Landscape Architects are asking for?

Landscape architects seek products with a proven track record, particularly for applications where product failure could result in liability. When designing emergency access roads, it is crucial to ensure that the chosen product can support the vehicles required to save lives during fire or medical emergencies. Additionally, landscape architects look for solutions that accommodate deeper root systems, allowing for the growth of larger and taller plants, thus enhancing the overall landscape design with more visually appealing elements. Grasscrete addresses these requirements by offering a reliable and established solution that not only provides durable support for emergency vehicles but also allows for the cultivation of diverse plantings, enabling landscape architects to create captivating and engaging designs.
