Mark Project Area:
Once the project layout has been determined, mark or spray paint the
overall outline, approximately twelve inches wider than the planned
installation area. This will provide the additional excavation area needed
for installing edging. Any pavers that abut structures or other paved areas
will not require installed edging and therefore do not require the additional
twelve inches of excavation.
SITE PLANNING AND MARKING
1
IMPORTANT:
Locate Utilities. Prior to beginning the installation, ensure all underground utilities
(e.g. electrical lines, phone lines, water lines) have been properly located and identified.
Subgrade:
The subgrade is the existing soil or surface that the installation will be built
upon. Subgrades that are primarily clay or silt are the weakest subgrades
and typically require additional base material.
Geotextile:
Geotextile material can be used to help prevent poor subgrade conditions
from mixing with the base material. Heavy foot or vehicular traffic
conditions are also good conditions for using geotextiles. The geotextile
will be placed between the subgrade and the base material.
Base (Non-Permeable Applications):
Base material should be a dense graded aggregate. Aggregate graded to
3/4" minus is a commonly used base material, often referred to as “class
5” or “road base.” Please refer to local requirements and specifications or
ASTM D 2940 for further information. Do not use stone dust or screedings.

IMPORTANT:
The preparation of the site and base material is critical to a long lasting, flat and premium
looking installation. Also, a properly prepared site will reduce installation time. Please
contact a landscape professional if required.
