Important Information

Eco-Stone allows for maximum drainage while maintaining a drivable surface. The void space of  10.8% between the stones allows for natural drainage and migration of rain water into the earth below. Base preparation must be an open graded system.

Base Requirement & Bedding Course –  open - graded paver base specification.  

Handling and Installation– A protective pad is recommended when doing the final paver compaction. Care must be taken toavoid tossing stones so that they bang against each other. Damage to the surface appearance can happen if handled too rough. Installed mechanically or by hand.  

Jointing Material and Joint Stabilization - permeable
