Castle Discovery - Safety Surfaces
Grass Mats

You can see grass starting to grow through the Grass Mat
After a few months the grass mat will become virtually invisible as the grass grows through it. The grass can be mowed normally over the grass mat. We have used the Grass Mat Safety Surface for Schools, Creches, Restaurants, Pubs & Domestic Gardens; areas from 30m2 to 400m2.
The Grass Mat Safety Surface has a critical fall height of 3m, when installed in accordance with EN1176. It is a rubber grass mat system with a fibre mesh underlay, which allows the grass to grow through it. It is ideal for large areas and is more forgiving of slightly uneven ground than Rubber Safety Tiles. It costs a lot less than 'Wet Pour' ( A rubber safety surface which is installed as a wet mix, then hardens). The Grass Mat Safety Surface requires very little site preparation. Level or gently sloping sites will achieve the best results.
Main advantages of Grass Mat Safety Surface:
3 Metre Critical Fall Height Achieveable when placed on Soil/Grass.
Easy to install.
Easy to replace if damaged.
Good anti-slip qualities.
Least Expensive of all Safety Surfaces
Main disadvantages of Grass Mat Safety Surface:
Not Designed for Concrete Base.
Only Available in Black.
Safety Tiles

They are available in 4 colours; Green, Red, Blue and Black.
Main advantages of Safety Tiles:
Easy to install.
Easy to replace if damaged.
Good anti-slip qualities.
Total control over depth of Safety Tile, therefore control over Critical Fall Height.
Main disadvantages of Safety Tiles:
Difficult to create curves.
Difficult to do complex designs and patterns
Our most popular Safety Tiles thicknesses are:
25mm (4 tiles per m2) Critical Fall Height 0.8m
45mm (4 tiles per m2) Critical Fall Height 1.4m
60mm (4 tiles per m2) Critical Fall Height 1.7m
110mm (2 tiles per m2) Critical Fall Height 3.0m
Please note that when preparing the base: we recommend a fall of 1 in 50 to ensure good water run off / drainage.
Wet Pour


Wet pour as it's name suggests is installed wet. It is the most expensive of the Safety Surfaces. It must be laid on a firm, flat base, with good drainage/water run off. It provides similar protection to Safety Tiles (similar Critical Fall Heights).
Generally specified for prestige projects with large budgets.
Main advantages of Wet Pour:
Large range of colours available.
Allows creative designs & patterns to be incorporated into the safety surface
Good anti-slip qualities.
Main disadvantages of Wet Pour:
Difficult to repair if damaged.
Specialist Installation only (cannot be DIY).
Most expensive of all safety surfaces.
Installation - conditions must be dry and temperature must be above 10ºc to install.
What exactly is Wet Pour?
It is made up of two layers. The bottom layer (goes down first) is a wet mix of recycled shredded black rubber and glue, normally mixed in a cement mixer. This layer provides the majority of impact absorption and represents approximately 80% of the depth of the finished Safety Surface. The top layer (goes down last) is made from coloured virgin rubber granules (EPDM). Creative artwork & designs are possible using a wet mix of coloured EPDM. Spectacular Safety Surfaces are achievable with Wet Pour.
