One of the most important factors, determining the safety of the playground or sport area is providing the high-quality fall absorbing safety surface. Properly installed safety surface, allows to avoid many dangerous injuries.

There is a variety of materials of safety surfaces available providing impact attenuation, including synthetic surfaces like:
Safe playing has absolute first priority in Lars Laj therefore each individual playground Lars Laj is providing is compatible with all the present international standard of safety in playground equipment. Our playground system has been certified, tested and approved by TÜV in Germany according to the newest European standard DIN EN 1176-1177.
Play areas of Lars Laj are equiped in the most advanced technology available in safety surfacing as well as in traditional kinds of nature surfaces like grass, gravel or sand.

Artificial grass Lars Laj Proplay - Lars Laj Proplay system consists of impact mats, covered with artificial grass, providing a safe, clean and dry play surface for children. Proplay mats are produced in a unique process from high quality polyethylene foam, having closed cells. Owing to this, it is possible to receive mats of high durability, simultaneously preserving high flexibility. |
 | Natural surfaces - Grass, sand, gravel, wood chips and bark surface are the most often used type of natural safety surfacing for outdoor playgrounds. However they are recommended rather for low play-eqipment. For playgrounds with platforms installed in higher level synthetic surfaces would be a much better solution. |
 |
Wetpour - One of the best safe surfaces you can have. It can be laid directly onto hard surfaces like tarmac with ramped edges. It saves time and money on base works. Lars Laj is able to supply wetpour surfaces in a variety colours according to client demands. |
 |
Rubber Tiles that can be laid on asphalt or concrete pavement. They are connected with an adhesive substance. As they don't crack you can be sure they will last for a very long time. Rubber tiles are produced from coloured rubber granulate with grain size of 1-3 mm, connected with polyurethane glue. The combination of those components gives as a result a safety surface of high impact absorption properties. |
 |
Rubber mats can be installed directly on loose surfaces like sand or gravel. The holes allow the grass to grow up through the mats and thereby create a green area. With a system of plugs the mats can be easily installed directly on sand or gravel after the surface has been leveled. The safetymats are suitable for both sport and play areas. |
Of course each type of surface has its advantages and disadvantages. Norm DIN EN 1177 issued by the European Committee for Standardization (CEN) regards to standard specifies requirements for surfacing to be used in children's playground and specific requirements for areas where impact attenuation is necessary. The table below contains basic examples of materials used as safety protective surfacing.
| Surface | Thickness [mm] | Critical Drop Height [m] |
| SUREPLAY 40 mm | 40 | 1.3 |
| SUREPLAY 50 mm | 50 | 1.5 |
| SUREPLAY 70 mm | 70 | 1.9 |
| SUREPLAY 80 mm | 80 | 2.4 |
| SUREPLAY 90 mm | 90 | 2.6 |
| SUREPLAY 100 mm | 100 | 3.0 |
