Geotextile membranes form part of the structural build up of a horse arena, helping control separation, drainage and long term stability within the base layers. Used correctly, they reduce contamination between materials, support consistent drainage and help the arena perform as intended over time. They do not compensate for poor ground preparation or inadequate sub base construction.
In a typical arena build, membranes are installed at different levels depending on their role. Woven geotextile membranes are commonly used at formation or base level, below the aggregate sub base. Their primary function is stabilisation and separation, limiting movement within the construction and helping distribute loads where ground conditions are variable or weak.
Non woven geotextile membranes are used where filtration and separation are required. These are typically installed above the aggregate layer and below the riding surface to prevent fine materials migrating into the stone while still allowing water to drain freely. Non woven membranes are also used to wrap land drains and drainage trenches to reduce the risk of silting and long term blockage.
Membrane grade selection depends on arena use, maintenance regime, surface type and ground conditions. A lightly used private arena places very different demands on the build up than a commercial or competition facility. Higher use arenas generally require heavier non woven grades with improved puncture resistance and durability.
All geotextile membranes used in horse arenas must remain fully buried within the construction and should never be exposed or come into direct contact with horses. Adequate overlaps, typically 300 to 500mm, and careful placement during installation are essential to prevent movement or damage before the surface is completed.
This category includes geotextile membranes suitable for base layers, separation layers and drainage support within equestrian arena construction. Selection should always be based on ground conditions, intended use and the overall arena design.
