How it works
The turf-bearing layer is the top layer of the ground below the sod. In the major “vegetation unfriendly” football stadiums the turf-bearing layer is of particular importance as it is always involved in drainage and root growth.
Washed sands, lava sands and sieved top soil that is free of stones are used as major structural components. Peat and quality compost are suitable structural components. The mixture ratios are adjusted to the respective local conditions according to the structural components‘ grain sizes and mixed under constant laboratory control.
A soil shaft mixer with an integrated digital balance that guarantees “crumble-friendly” mixing is best for producing the mixture. Nowadays the turf-bearing layer is applied evenly in one layer using a laser-controlled bulldozer that operates forwards or a special finisher.
When using the finisher for installation, it must be ensured that the underlying drainage layer is only driven on by tracked vehicles or special-purpose dumpers with balloon tyres. We can apply both installation techniques as our fleet of vehicles includes all required vehicles.
We also have developed special techniques and procedures for the treatment of old turf-bearing layers that ensure both sporting and economic success.
