Gravel Grids for driveway 
Prodrive 30 with honeycomb structure 

Our Prodrive 30 is suitable for car and light van use it will take up to a 20mm Gravel and has a built in 90gsm membrane on the bottom unlike many others on the market that are only 70gsm 
  free draining too; so unlike tarmac and concreate you wont need to install drainage first.

The membrane is attached to the grid during production and they are both made of the same material.
This means that the 2 are chemically bonded to each other and cannot be separated.
Other grids on the market have the membrane glued to them so they can become separated after installation. This can lead to the grids rising to the surface through the gravel.
Our grids are also quite flexible. This allows for some undulations in the ground that the grid will flex to.
Other grids are so rigid that this can cause them to flip up when a car drives over them and they sink into the undulation below. 
Prodrive 30 is a recycled material so can be fully recycled without separation of the membrane from the grid.
