INDOOR BASE SPECIFICATIONS
FOR INSTALLATIONS ON
CRUSHED AGGREGATE
A Soil Analysis is not required
for normal indoor installations where
A concrete or ashphalt base is used or where a crushed stone base is
to be used (Verses concrete or asphalt). For fields that will have outdoor and weather exposure, a soil analysis is suggested.
These results will determine the final specifications.HOWEVER,for both indoor and outdoor applications, it is required that
we receive a small sample of the crush stone/gravel that is to be used for the installation. Different regions of the country
have various qualities of crushed stone available. You are responsible to have the base prepared and ready for installation
to our specifications.
Indoor soccer field applications must
be installed on compactable materials (crushed stone) according to standard construction requirements shown below.
When compacting, keep the
materials dampened in order to eliminate segregation of the materials and to attain
the proper level of compaction.
Should the field need
to support heavy vehicles, consideration must be given for the load bearing requirements of the base. Laser grading is recommended for all the layers of stone.
CRUSHED STONE BASE SPECIFICATIONS:
1 . Remove the organic topsoil to the
level of the soil bed. This is usually about 4 inches or so. If you already have
an organic free surface than the base can be created as a “pad” using the crushed stone as specified.
2. Compact the rough grade of natural soil with a vibrating or static roller as local soil conditions dictate. You
want a good, dense, compacted base to 95 degrees Proctor.
3. Depending on the soil conditions, we require a minimum of 6 inches of crushed
aggregate (gravel). The first 4” of this aggregate must be compacted to 95% Standard Proctor. It should consist of 0-3/4
minus aggregate and the leveling of this base course shall not exceed 1” in 20'.
4.The
final finished grade course aggregate shall be no larger than 0-1/4 " and be approximately 2” in depth. This final 2”
layer of aggregate must be rolled to achieve a nice, smooth finish, ready to accept the 15’ wide rolls of the turf system,
and shall be leveled to a uniform flat surface. The final grade aggregate must be stable so as not to be displaced by foot
or vehicular traffic.
5. The edge of the sports turf system is buried by our install crew under aggregate. The local owner/operator
always has the option to finish the edge with a treated wood or recycled plastic curbing. This is advisable at entrances or
where high foot traffic will occur. This curbing can be fastened the synthetic
grass with nails or screws every 8".
6. Drainage must be considered if the base is to be exposed to the elements prior to the installation of an
air supported structure. A soft base is very hard and costly to correct once the covered tension fabric structure or other
building is installed. Peripheral exterior drains are essential if you are installing an air structure since the footings
can be affected by the freeze than cycle. A local contractor can advise you on a variety of options so that moisture is drained
away from your building.
7. When a dasher board system is used, it is preferred to install the turf system prior to the boards
so that the turf is set under the boards for future stretching.
