Grasspave2 and Gravelpave2 are the only porous pavers with ADA ATSM certification per the DOJ since 1995. Our solutions provide a smooth, stable and accessible surface that is aesthetically pleasing for all ADA users. Our pavers will never “pop up” like the rigid pavers because ours are flexible and are unaffected from the freeze/thaw cycle, yet still provide the highest strength capacity in the industry with an astounding 15,940 psi (2,295,000 psf) due to the cylindrical design.
Fire departments rely on Invisible Structures products to create ADA-compliant fire lanes and companies like Disney and Tesla have installed parking lots and driveways to increase accessibility on their properties. Additionally, beaches, grass surfaces and pedestrian walkways become smooth and stable surfaces with the addition of our products.
Grasspave2 and Gravelpave2 were the first porous pavers to be ADA tested and approved. The flexible mats are forgiving with gradients and undulations on the paved surface, making wheel rotation easy and smooth. Meeting ADA requirements has provided us with the opportunity to participate in prestigious installations such as the Pentagon Memorial, Reliant Stadium, the National Botanic Gardens and the Oakdale National Preserve.
Invisible Structures products provide a stable and level surface that is conducive to wheelchair users, individuals with mobility aids, and those with ambulatory impairments. Its smooth and even texture ensures easier navigation for people with mobility challenges, allowing them to move freely and independently within outdoor spaces.
Our solutions are designed to offer sufficient traction, reducing the risk of slips, trips, and falls, particularly in wet or slippery conditions. This is crucial for ensuring the safety of all pedestrians, including those with mobility limitations, who may require additional support to maintain stability while walking.
Porous paving eliminates barriers commonly associated with traditional paving materials, such as uneven surfaces, cracks, and gaps, which can pose challenges for individuals with disabilities. By providing a seamless and obstacle-free pathway, we help promote universal access and create a welcoming environment for people of all abilities.
Grasspave2 and Gravelpave2 allow water to permeate through the surface and infiltrate into the ground below, rather than pooling on the surface or creating puddles. This helps to maintain a dry and safe walking surface, reducing the likelihood of hydroplaning and making outdoor areas more accessible for individuals with mobility impairments.
Create custom layouts, patterns, and color schemes to suit the specific needs and aesthetics of the environment. With our products, designers and architects can incorporate ADA-compliant features seamlessly into outdoor spaces, while still maintaining visual appeal and architectural integrity.
Note: For ADA applications it’s recommended to fill the rings of Gravelpave2 to the top only. Do not overfill. Avoid using pea gravel, use a sharp angular aggregate for best traction.
All Invisible Structures products are made from 100% recycled plastics (HDPE & PP – post-consumer and post-industrial), making them safe for our underground environments and waterways, and promoting a circular economy.
