PART 5 - INSTALLATION:
Weather Conditions. - Because the polyurethane agents are moisture or heat sensitive, the
nighttime temperatures must be above 40 degrees with daytime temperatures around 50
degrees. These temperatures must be consistent for several days before and after the poured
rubber installation period. Complying with these weather conditions will prevent poured rubber
from freezing which prevents proper curing.
Thickness - Overall depth of the poured rubber will vary based on critical fall heights and
installers test results. Depth of EPDM/TPV will be no less than 0.5”. Installation is performed
by technically trained GameTime approved specialists. Your GameTime dealer will schedule
installation of playground surfacing to meet your requirements.
THICKNESS CHART _ - (Below depths include 0.5” EPDM/TPV Topcoat)
1' to 4' Critical Fall Height 1.5” to 2” Total Depth
5' Critical Fall Height 2” to 2.5” Total Depth
6' Critical Fall Height 2.5” to 3” Total Depth
7' to 8' Critical Fall Height 3” to 3.5" Total Depth
9' to 10' Critical Fall Height 4” to 4.5” Total Depth
11' to 12' Critical Fall Height 5.5” Total Depth
Cold Joints - Areas in excess of 2,000 square feet or areas that require adjacent color pours will
have a cold joint or seam. Although seldom visible, seams are necessary when large pads require
more than one day pours.
Edges - Surface edges shall be flush, beveled or rolled. It is important to advise what type of edge
will be required so that the appropriate amount of materials are ordered.
Flush_- When curbing is provided around the outside perimeters of the pad, the poured rubber
will be adhered to the edge of the curbing so that the rubber surfacing is flush. This allows for a
smooth transition into the play area. However, the sub-base should be installed to allow the
proper depth of poured rubber so that the flush edge can be installed without having to fill voids
by increasing the depth SBR materials. If the sub-base is not installed properly, using too much
of the SBR materials can cause the installer to run short on the cushion course which is require
a change order to add additional materials for the project.
Beveled - When curbing is not provided for concrete or asphalt sub-bases, the installers will
bevel the edge down along the edge of the pad. This type of edge can be sloped to provide a
smoother transition but will require additional materials. If beveled at the edge of the use zones,
the edge can be more round due to the depth of the poured rubber. In this case, you may want
to have a rolled edge added to allow a smooth transition for wheelchair users.
