Playground Safety Surfaces Many families and organisations want to provide a dedicated and safe play area for their children. As with our play equipment, we can offer you advice, supply only or supply and installation depending on your requirements. All the products we sell have been tested and given approval for their Critical Fall Height (CFH) ratings (e.g. this is usually the deck height on a climbing frame). As a quick guide to each safety surface; Play Bark - low cost per square meter, depth can vary, requires membrane, retaining walls and regular topping up Lawn Mat - easy to lay, low maintenance (i.e. grass mowing), 2m CFH (approx. £10 - 15/sq m)* Grass Mat - easy to lay, low maintenance (i.e. grass mowing), 3m CFH, more expensive (approx. £15 - 20/sq m)* Play Tiles - good finish, 3 colours available, guaranteed CFH, installation difficult (approx. £45 - £100/sq m) Wetpour - superb finish, guaranteed CFH, can include coloured patterns, installation difficult (approx. £100 - 150/sq m) * - requires Ground Stabilsing Mesh for use with commercial play equipment. This help maintain the CFH by preventing the mat sinking into wet soil after heavy use. Approximate cost £2.50/sq m.
