Get Started!
Decide where you wish to install the Drivable Grass. Go to www.soilretention.com for design ideas.
Determine the number of mats required to complete the project (mats are produced in 2' x 2' sections).
Refer to Table 1 to determine base layer and how deep to
dig. Your local landscape store can assist in determining the
proper materials to use as a base. Table 2 is a cross section
of a standard installation. |
Prepare The Area
Mark the area
(use a string line, powdered chalk, or flexible hose).
Clear the area
(remove grass, sod, or organic materials).

Dig It, Fill it up & Pack it in.
Dig to the suggested depth determined in Step 1 using Table 1.
This is the time in which to install any irrigation or lighting system.
If no base layer is required then proceed to Step 4. Otherwise, backfill with necessary base to within 3 - 4.5 inches of the surface with a well compacted and leveled granular base material.
