High Load-Bearing Capacity
Grasspave2 and Gravelpave2 have an extremely high load-bearing capacity (15,940 psi/2,295,360 psf – which translates to at least the ability to support an F-15 fighter jet during takeoff.) This is due to the independent column/ring design making each ring capable of bearing a surprising amount of weight, and a group of rings under a tire incredibly strong. This ensures that your driveway is properly supported.
Resistance to Weather Conditions
Invisible Structures porous paving products can withstand extreme temperatures, heavy rainfall, and freeze-thaw cycles without “popping up” or popping out like rigid pavers. This is because the grid itself is flexible and gives way when the ground expands and contracts. It also means it’s easy to mow and plow all year around for the lifetime of the installation.
Low Maintenance
Our innovative solutions require minimal maintenance, saving you time and resources in the long run. Gravelpave2 has a filter fabric design, exclusive to Invisible Structures that will never come off, never disintegrate, prevents gravel migration, prevents paver “pop up”, and prevents the growth of weeds from underneath. This eliminates the need for constant upkeep and paver replacement.
Rainwater Management
Rainstore3 can be placed under a driveway using Grasspave2 or Gravelpave2 for water drainage, capture, storage and potential re-use.
Heat Island Effect Reduction
Traditional pavement surfaces can contribute to the urban heat island effect, increasing the temperature in built-up areas. Invisible Structures Porous Paving Products help reduce this effect by capturing heat, maintaining a cool surface and even reducing sound.
Recycled Materials
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.
