95%. Finish slope of porous aggregate should be 2% from the centerline of the area to the perimeter, and the grade should not vary more than a quarter inch (¼”) in ten feet (10’).

C. The sub base should be installed in two inch (2”) lifts to appropriate thickness.

D. The sub-base should be compacted using vibrating tamper, to approximately 95% Proctor density.

E. The sub-grade should no longer have any vegetation.

F. Sublevel grade is to be compacted prior to the ABC aggregate installation. Particular attention should be paid to areas of disturbed earth such as where footers for playground equipment enter the ground. Concrete used to fill said areas/footers should be poured to the top of sublevel surface.

G. The sub-base installer and architect will accept the aggregate base in writing prior to the installation of the poured in place system.

H. Any alterations must be agreed between all parties.

I. Hard Base Construction: For concrete surfaces, shot blast, acid etch or power scarify as required to obtain optimal bond of the Cushion Layer to the concrete.

This procedure should be continued until all areas are complete.

B. The urethane primer should be applied to any playground equipment that will be surrounded by the poured in place safety surfacing system.

4.02 Cushion Layer

A. The components of the poured in place safety surfacing should be mixed on site in a mixer to ensure a comprehensive mix according to manufacturer’s instructions.

B. The cushion layer comprised of SBR buffings shall be mixed with the aromatic or aliphatic moisture cure polyurethane binder at a rate of 12% of the total weight of the material thoroughly so that the binder is evenly dispersed into the rubber base. Or;

C. The cushion layer comprised of non-tire derived SBR & EPDM Chunk Rubber shall be mixed with the appropriate amount of urethane so that the binder is evenly dispersed into the rubber base.

D. The cushion layer mix should then be spread and troweled to the desired depth and allow to cure for 24 hours.

4.03 Wear Course Layer

A. The wear course layer should be mixed with 1-3mm EPDM granules and urethane binder at a rate of 20% of the total weight of the materials so the granules are covered thoroughly and evenly.

B. The wear course layer mix should be spread and troweled to a depth of a half inch (½”).

C. Where seams are required due to color change, a step configuration will be constructed to maintain wear surface integrity. Step seam shall overlap a minimum of 4”. Butt seams are not acceptable.

D. The finished texture shall be slip resistant, smooth and even.

E. The poured in place surface should be allowed to cure for 24-72 hours or until dry to the touch.
