Invisible Structures has been spearheading tough, environmentally friendly ADA Porous Grid Paving products for over 40 years. Grasspave2 and Gravelpave2 are engineered to provide the perfect balance between durability, performance and sustainability, creating the most compliant commercial and residential surfaces, walkways, pathways and trails! With easy installation, low-maintenance, versatility, rapid drainage, and a 60+ year lifespan, our rugged products dominate in any climate. Pave Green. Pave Strong. Pave Safe.

Easy Installation

One of the key advantages of Invisible Structures Porous Paving Products is their ease of installation. Our products are designed to be user-friendly, making it simple for contractors and DIY enthusiasts alike to install them quickly and efficiently.
Grasspave2 and Gravelpave2 arrive in various sized large rolls made up of huge grid panels – each larger than a yard, and can simply be rolled out over the ground (without laying down each tiny part like a rigid paver) greatly reducing the time and effort
required for installation. Either nail down Gravelpave2with the included American-made, 8-inch pins and washers – or don’t with Grasspave2 because the grass roots will take care of that for you in several weeks. Our product Hydrogrow is included with Grasspave2 to help get the grass roots going. This quick installation not only saves time and labor costs but also makes things easier in general.

Versatility and Customization

Invisible Structures Porous Paving Products offer a wide range of design options, allowing you to create customized walkways and pathways that perfectly complement your project’s aesthetic. Gravelpave2 is available in various colors, providing endless possibilities for creating unique and visually appealing surfaces. (Crushed shells, recycled glass, pea gravel and black lava stone are just a few filler that have been used with Gravelpave2 to create different aesthetics – please contact Invisible Structures corporate if using one of these, for tips regarding maintenance and porosity)

Additionally, since Grasspave2 is never seen from the surface, Grasspave2 and Gravelpave2 can be easily integrated with other landscaping elements, such as planters, benches, and lighting, to create a cohesive and attractive outdoor space.

Accessibility and Safety

Since 1995, our porous paving products have been the only porous pavers with ADA ASHTO certification to be a smooth and stable surface, per the DOJ requirements. Grasspave2 and Gravelpave2 has been used at countless corporate headquarters, school
campuses, hospitals, hotels, government buildings and private residences – specifically for its ADA purpose. The permeable surface provides an excellent turning ability, traction in wet conditions, and remains a smooth, stable surface throughout the life of
the product without any “pop up’s” like rigid pavers from the freeze/thaw cycle. This ensures the safety of all users, regardless of their abilities.

Environmentally Friendly

All Invisible Structures Products are made from 100% recycled plastic (HDPE and PP) and have been since the 80’s, back when we sourced and ground our own plastic. At one point in the 90’s, we were the largest plastic recycler West of the Mississippi. Plus, the permeable nature of Grasspave2 and Gravelpave2 allow rainwater to pass through the surface, reducing runoff and flooding on the surface, while promoting groundwater recharge – which is one of the most depleted water sources on Earth.

Durability and Low Maintenance

Grasspave2 and Gravelpave2 are built to drain faster than any other product on the market, withstand the heaviest foot traffic, and hold up to the harshest weather conditions, ensuring that your walkways and pathways remain functional and
attractive for years to come. The 100% recycled HDPE used in our products never crack, chip or fade – because they’re never seen from the surface (except perhaps the tops of the Gravelpave2 rings – but all of our plastic has a UV inhibitor) requiring minimal maintenance and reducing long-term costs. And our sourced plastics will never leach into the ground or water.

Cost-Effective Solution

Invisible Structures Porous Paving Products offer a cost-effective solution for constructing walkways and pathways. The quick and easy installation of Grasspave2 and Gravelpave2 vs. rigid pavers or concrete, low maintenance requirements, and long-lasting durability (60+ years!) of our products make them a smart investment for your project. Additionally, the environmental benefits of our products may qualify your project for tax incentives or credits, further reducing costs.

Grasspave2 and Gravelpave2, by Invisible Structures, provide an install-friendly, accessible, and sustainable solution for constructing commercial, residential, and public walkways and pathways. With their ease of installation, versatility, safety features, environmental benefits, and cost-effectiveness, our products are the ideal choice for your next project.
