For areas under heavy usage (riding arena, lunging ring) we recommend installing in layers consisting of a base layer, an equalizing layer, the paddock slab filled with material as separating layer and then a top layer of footing.
A permeable layer (approx. 20–25 cm (7.87–9.84”) of crushed rock, lava or gravel is applied to soil with good bearing capacity and compacted afterwards. A 2–4 cm (0.79–1.57”) equalizing layer of grit is subsequently applied and leveled.
The slab serves as separating layer. It is filled with grit, sand or gravel and prevents the mixing of base and footing layer. Separation can be improved by placing a permeable fibrous web under the slab.
Finally, the footing is applied. It may consist of sand, wood chips, fabric based or similar material.
For use in less stressed areas (paddocks, feedlots, access paths) the sub-base can be reduced according to the expected strain or the slab can even be placed directly on natural ground. It cannot be guaranteed though that the slab will not sink into the ground.
