Play Surfaces Safety Information & Recommended Depths

Hallstone Play Sand and Hallstone Wood Playchips meet British Standard BS EN 1177:2008 - Impact Absorbing Playground Surfacing when used at the recommended depths.

This European Standard specifies requirements for surfacing to be used in children's playgrounds and specific requirements for areas where impact attenuation is necessary. It suggests the factors to be considered when selecting playground surfacing and gives a method of test by which the impact attenuation can be determined. This test gives a critical fall height for surfacing, that represents the upper limit of its effectiveness in reducing head injury when using playground equipment conforming to BS EN 1176.

The BS EN 1177:2008 recommended depth of coverage for Play Sand is*: 

  • 150mm - 300mm at a critical fall height of up to 2.5 metres.
  • Minimum of 400mm depth at a critical fall height of up to 4m

Each bulk bag will cover approximately 4m² at a depth of 150mm, 2m² at a depth of 300mm and 1.5m² at a depth of 400mm.

The BS EN 1177:2008 recommended depth of coverage for Wood Play Chips is*:playchips_dry.jpg

  • 150mm - 300mm at a critical fall height of up to 4 metres.

Each bulk bag will cover approximately 4m² at a depth of 150mm & 2m² at a depth of 300mm. We would always recommend wearing sensible footwear to avoid splinters, which can occasionally occur when using wood-based products as a safety surface.


*We would recommend adding a further 10% to the depth when installing to allow for settling.
