"This hill has never been so smooth to get up and down" - Customer.
Geocell is a three-dimensional grid designed to hold material in place and create a solid foundation. Once expanded and filled with compacted material, they provide strenghth, stability and load support for the driveway, even on steep inclines. When installing on sloped areas, it is crucial to use a material that compacts and interlocks. i.e. road base type material that has characteristics of crushed, angular rock with a mixture of fines.
