Concrete / Asphalt Base Requirements

1. DEPTH 3" minimum thickness

2. SLOPE Concrete shall maintain a slope of at least 1/4" per foot. Base must exhibit positive drainage.

3. TOLERANCE Concrete must maintain a tolerance of 1/8" in 10' to avoid low areas that will hold water under the safety surface. The slab contractor shall be responsible for flooding all slabs to insure proper slope and tolerance and to avoid delay charges. Any areas holding 1/8" to 1/4" of water shall be patched prior to arrival of ProDek crews.

5. DRAINAGE Drainage at the low end of your concrete slab is of utmost importance. Any brick walls or curbs at the low end of the slab shall have drainage access through weep holes. Weep holes shall extend a minimum of 2" above top of concrete slab and a minimum of 1/8" below top of concrete slab, as ProDek is porous and water drains immediately through it. Weep holes shall be 2" high and 1" wide and shall be installed every three (3) feet. If weep holes are smaller
than the recommended size, they shall be installed every 18".

6. DRAINS Floor drains shall be located outside of required high impact areas; it is recommended that drains be covered with ProDek safety surface. Recommended locations for drains are under play unit or against low-end wall or curb.

7. FINISH Concrete should be finished with a medium broom finish.

8. SCHEDULE It shall be necessary for all work in and around the concrete base to be completed prior to the arrival of ProDek crews - including playground equipment, fencing, tile/pavers, walls, etc. If you anticipate any delays in preparation of the area to be surfaced, please notify ProDek in writing at least ten (10) days prior to our scheduled arrival.
9. EQUIPMENT No equipment is to be installed directly on the ProDek surface.

10. PERIMETER EDGE See ProDek detail sheets for perimeter edge requirements. NOTE: If over asphalt, ProDek recommends the attached keyway detail be provided prior to the safety surface installation.

NOTE: Although ProDek Inc. shall advise owner and/or prime contractor if a deficiency in work-by-others is discovered, ProDek accepts no responsibility for work-by-others. It is the owner and/or prime contractor's responsibility to ensure the accuracy of work not executed by ProDek Iinc.. Prime Contractor and Owner agree to release ProDek Inc. from responsibility to repair defects that are the result of defects in the base/subgrade.
