O) G-max test is recommended at the completion of the turf installation.
P) The entire system will be constructed to maximize dimensional stability, to resist damage and normal wear and tear from its designated use, and resistant to ultraviolet rays.
Q) All adhesive used in bonding the system together will be resistant to moisture, bacterial and fungus attacks.
R) Lines will be tufted-in place or inlaid per owner specifications. All colors shall be manufactured with the same type fiber used in the main playing area.

Sub-base Earth
A) Remove all soils as required to obtain architects desired elevations.
B) All soils to be removed off site or as directed by owner.
C) Sub base earth should be laser graded to within 1⁄2” of sub grade elevation. Check for soft soil lenses or other unsuitable soils which could cause settling.
D) All disturbed earth shall be compacted to a minimum of 90% ASTM with optimum moisture content +- 3% prior to installation of rock base.
E) Install Geotextile Membrane.
Aggregate Base
A) Stone base shall be per specification. Stone base shall be laser graded and installed in lifts as needed to achieve final grades within 1⁄4”. Aggregate Base: Stone material shall conform to specifications for 100% crushed stone and shall be “washed”, free from fines and debris. Stone shall be angular and not rounded. Crushed concrete, limestone fines, slag, etc. shall not be allowed. Base stone shall be 1” washed with permeability greater than 40” per hour. Top stone shall be 3/8” to 5/8” washed with permeability greater than 12” per hour.
B) Stone base shall be compacted to maximum ASTM +- 5% for the type of rock specified. All rock shall be CLEAN rock allowing proper flow of moisture to the under drain system (no fines allowed).
Drainage
A) Field drains shall be Colbond Enkaturf at 12” x 1” set in a herringbone design on 20’ centers.
