Why Are Membranes Essential for Horse Arenas?
When it comes to horse arenas, standing water can create a hazardous environment. Not only does it make the surface slushy and unstable, but it also poses risks to both riders and their horses. Over time, water accumulation can damage the sub-layers beneath the arena, leading to uneven surfaces and soft spots. To prevent these issues, proper drainage and high-quality geotextile membranes are crucial. Without them, you might face costly repairs or even legal liabilities if accidents occur.
What Are Geotextile Membranes?
In simple terms, a geotextile membrane acts as a barrier between different layers of materials, preventing them from mixing. For horse arenas, this means keeping the sand separate from the underlying sub-layers, ensuring the sand remains stable over time. There are two main types of geotextile membranes: non-woven membranes, which allow water to drain quickly, and woven membranes, which are less expensive but don't offer the same level of drainage. Non-woven membranes are typically placed above the sand and below the drainage pipes, while woven membranes are used at the base layer since the water is already managed by the underground drainage system.

What Types of Membranes Are Available?
Geotextile membranes come in various brands, colors, and weights. Popular brands include Terram and Lotrak, which we carry in stock. Black membranes are generally woven and designed for the base layer, while white membranes are non-woven and used for the upper layer where sand sits. Membranes are measured in grams per square meter (GSM), with higher numbers indicating thicker, stronger membranes. For a horse arena, a minimum of 300GSM is recommended due to the heavy foot traffic.
Typically, a 100GSM membrane suffices for temporary arenas, 200GSM for light-use arenas, 300GSM for medium-use arenas, and 500GSM for permanent, heavily trafficked arenas. A common setup involves placing a black woven membrane at the bottom and a heavier white non-woven membrane on top for optimal performance.
What Do They Do?
Primarily, geotextile membranes separate aggregates, prevent the loss of sand, stabilize the ground, and facilitate water drainage without allowing particles to clog the drainage system. They are indispensable in horse arena construction because, without them, the drainage system would quickly fail, leading to waterlogging and eventual sand erosion. This could result in dangerous pits and puddles, posing risks to both riders and horses. Proper drainage ensures a safer riding experience.
We often see customers trying to cut costs by choosing inappropriate membranes. Using black woven membranes for both layers or opting for a lightweight white non-woven membrane like the Terram T1000 for a permanent arena can lead to disaster. While saving money initially might sound appealing, it could result in costly replacements or, in extreme cases, lawsuits if accidents happen.
