B-Safe Rubber Mulch Installation Instructions

16’ Fall Height Rating/6-inch Installed Depth Services


Playground Design and Fall Zones

A landscape architect or certified engineer involved in the playground design and planning
process should be consulted regarding the topography of the installation area.
Proper drainage, preventing water from accumulating in the play area, must be maintained. In
order to ensure proper drainage factors such as climate, soil conditions, and the overall
topography of the installation site need to be considered.

Proper fall zone guidelines need to be followed in the design and installation process to ensure
that all fall zones are adequately addressed with the recommended installed depth for the height
of the structures being installed. The fall zone is the area under and around the equipment where
protective surfacing is required and should extend a minimum of six feet in all directions from the
perimeter of the equipment per CPSC playground safety guidelines (attached).

Ground Preparation

Installation area must be properly prepared prior to installation of B-Safe Rubber Mulch.
The area where B-Safe Rubber Mulch will be installed must be graded for proper drainage with
a substrate that is compacted to provide a firm, even base.

The area must be cleared of all grass, wood chips, rocks, stumps, gravel, or any other type of

Installation of a contractor grade geotextile landscape fabric is recommended under B-Safe
Rubber Mulch. Seam overlap needs to be a minimum of three inches and all seams need to be
properly secured to prevent dirt or other substrate material from mixing with the safety surfacing.
Additionally the landscape fabric needs to be properly secured at the perimeter and around all
installed equipment posts or polls. If stone or other material is used as part of a drainage system
then the use of landscape fabric is also recommended in order to ensure that the materials do not

If B-Safe Rubber Mulch will be installed above grade, use of a retaining system is highly
recommended to reduce migration of B-Safe Rubber Mulch outside of the designated area and
to help maintain a level, compacted play area.

Installation of Material

Install B-Safe Rubber Mulch at a uniform level throughout the playground. Any variety of
methods can be used for spreading the mulch including blowing, shoveling and raking. Care
should be taken to not disturb the substrate material and/or landscape fabric if used.
The amount of B-Safe Rubber Mulch used per square foot is dependent upon on the required
fall height rating. To achieve a 16’ critical fall height rating per ASTM F1292-04, 7” of uncompacted
B-Safe Rubber Mulch should be compacted to a 6” depth. To test for proper
compaction, one compacted square foot of B-Safe Rubber Mulch at 6” will equal 15.3 lbs per
square foot.

To reduce maintenance in high use areas where critical fall height protection is not required,
rubber mats may be used. Mats can be placed under or on top of B-Safe Rubber Mulch.

Regular Maintenance

In order to provide consistent head impact protection and accessibility of the playground,
maintenance is required. A level, compacted 6” depth of B-Safe Rubber mulch must be

Upon discovery of a thin, un-compacted or non-level condition, the surface of the playground
area must be raked and compacted to ensure consistent and proper installed depths.
Periodic replenishment may be required if B-Safe Rubber Mulch has migrated outside of the
play area, cannot be reclaimed and a level compact depth for the required fall height protection
cannot be achieved.
