WETPOUR TECHNICAL INFORMATION
Our wetpour surfacing is a multi-component polyurethane and rubber composite. It is formed in-situ by a chemical mixing, wet pouring, leveling, screeding and rolling process.
We use an EPDM rubber crumb combined with a polyurethane binder to create a long lasting, safe and aesthetically pleasing surface.
When installing wetpour as a safety surface, we use a two-layer system. SBR (Styrene Butadiene Rubber) granules form a base layer of the surface, producing the impact absorbent properties of the system. Whilst EPDM (Ethylene Propylene Diene Modified) rubber crumbs form the wearing course of the surface.
DEPTH & AREA SIZES
The depth of wetpour required is calculated according to the Critical Fall Height (CFH) of any fixed play equipment. This is the height from which a surface will absorb the impact of a child’s fall to reduce the risk of serious head injury. We are happy to advise of the CFH of any existing or planned play equipment.
The extent of safety surfacing required around the play equipment is dictated by the height of any potential fall. Establishing the size of the area that will need soft surfacing differs for stationary equipment and swings. Our guide provides you with in-depth details on how we establish depths and area sizes for play equipment.
SUB BASE REQUIREMENTS FOR WET POUR
Our wetpour safety surfaces can be laid onto a variety of sub-bases. The most common of these being; Type 1 MOT stone, Tarmac or concrete.
We can lay the surface onto other sub-bases, but please contact us to discuss. Our team of estimators are here to advise you on any aspects of sub-base or edging detail required.
The depth of sub-base can also determine the depth of wet pour. View the full specification for advice on preparing the most common sub-bases for wet pour safety surfacing.
ACCREDITATIONS & STANDARDS
BS EN 7188:1998 Tests safety surfacing to different criteria such as the determination of critical fall height, slip resistance, indentation resistance, durability, ease of ignition, tensile strength and elongation at break.
BS EN 1177:2018 Recommends that safety surfacing is used underneath playground equipment and gives guidance for area usage.
