Pour-in-Place Surfacing - What You Need to Know
Site Preparation
Area must be excavated to remove all organic materials that will decompose, settle, & affect surfacing
Drainage must be addressed as safety surfacing is porous
Suitable sub-base & edging installed (options below)
ADA compliant grading needed
Sub-base Options:
Crushed Aggregate – Comprised of a 4” minimum of 3/4” crushed stone
Concrete – Existing concrete must be free from major cracks & damage. New concrete must have a minimum of 14 days to cure.
Asphalt – Existing Asphalt must be free of any major cracks & damage. New Asphalt must have a minimum of 30 days to cure & must be power washed 3 separate times
Edging Options (Borders):
A. Concrete
B. Treated Timbers
C. Rubber Curbs
D. Beveled Edge- Angling surfacing down to grade (can't be done with stone)
E. Turn Down Edge- Angling surfacing down below grade, to be later back-filled by EWF, grass, etc. *PIP will not adhere to plastic timbers*
About the PIP System
Thickness of surfacing is dependent on the fall height of the play equipment
Wear course is made of TPV, cushion layer is made of Chunk (pre-consumer, post-industrial rubber)
Wear course only installations (no attenuating layer) must be installed over asphalt or concrete
Areas within the use zone of equipment must contain safety surfacing (communicated in square footage)
Urethane Options:
A. Aromatic (Standard, subject to amber)*
B. Aliphatic (Premium, does not amber)
*Ambering effect is temporary & mechanically wears off over time. It is an issue with aesthetics but does not hurt or compromise the longevity of the rubber.
Color Blends:
50/50 color is most popular (50% colored granules, 50% black granules)
Other blends include 75%/25%, 33/33/33, etc., up to 100% color.
Black/Colored granules are different types of rubber,
higher color concentration leads to a stronger surface (50% black is the max)
Maintenance/Installation of PIP Surface
Routine cleaning of debris on surface, power washing when necessary, Using approved products to clean surfacing. Work performed by owner
Maintenance spray coating strengthens the urethane bond of the pad, Makes existing colors more prevalent and increases longevity. Recommended every 3-5 years based on use. Work is performed professionally.
Repair options include patch repairs, seam repairs, perimeter repairs, or ½” wear course re-tops. Work is performed professionally.
50° and rising and no precipitation needed for installation. 70° for aliphatic.
