Aggregate Stones

The riding arena sub-base forms the foundation of any all weather riding arena. Whilst providing stability to the final surface, the sub base also acts as a temporary water storage reservoir during periods of heavy rain. This prevents the drainage system from being overloaded ensuring the surface is still useable in the wettest conditions.

It is critical that a free draining sub-base is used. This means using material that has been screened to remove fines which will impede waterflow and block drains further down the line.

Using Aggregate Stone

Once the drainage trenches are backfilled the site will be level again. You would then need to install the sub-base which should be a minimum of 4 inches (100mm) in depth but ideally 6 inches (150mm).

The sub-base forms the ‘foundations’ of an arena and is also very important to the drainage system. The sub-base layer will provide temporary water storage in the event of a heavy downpour thus keeping the upper surface free from waterlogging and also relieving pressure on the drainage system. Due to the water storage requirement it is essential that a clean angular material is used in a 75-40mm size.

The most common materials used are aggregate. A 75-40mm size range ensures the material compacts whilst remaining free draining. All materials should be free from dust/fines to prevent blockage of the drainage system. The sub-base material chosen will need to be levelled using an excavator and laser level and compacted in layers using a vibrating roller. A good excavator operator should be able to compact and level the sub-base to within +/- 5mm accuracy.

With the sub-base levelled and compacted the fencing can now be installed. Generally a 3 bar post and rail system should be used with the rails attached to the insides of the posts. This prevents potential injury to the horse and rider when riding close to the fence line.

Gravel boards should be attached to the bottom of the posts as these will contain the upper surface when added. It is preferred that posts are installed using a ‘Post Knocker’ which is a tool which will mechanically hammer the posts through the sub-base and into the subsoil below.
