Every equestrian knows the feeling. It’s the moment a horse steps onto a great riding surface and moves with confidence—a perfect balance of support, cushion, and stability underfoot. That ideal horse arena footing isn’t an accident; it’s the result of a carefully engineered system built with specific, high-quality horse arena materials. For champions across Southern California, that foundation starts right here at FST Sand & Gravel.
As the region’s leading supplier of aggregates and arena sand, we understand that creating a safe, high-performance horse arena is a science. It begins with knowing that a premier riding surface is far more than just a top layer of sand. It’s a dynamic, multi-layer system designed for superior drainage, durability, and the long-term soundness of your equine athletes. By sourcing your materials directly from our Corona quarry, you get the highest quality products, expert knowledge, and the convenience of same-day delivery.
The Foundation of Performance: Building Your Arena Base
Before you can choose your top footing, you must build a proper foundation. The best horse arena sand in the world will fail if the layers beneath it are not correctly installed. A professional riding arena is constructed in three distinct layers: the sub-base, the base, and the top footing.
- Sub-Base: This is the lowest layer, typically the existing, compacted native soil of your site. It must be graded with a slight slope of 1-2% to ensure water drains away effectively.
- Base: This is the critical load-bearing layer that provides the arena’s structural integrity. The base is a compacted, solid, and uniform layer, usually 4-6 inches thick, constructed much like the base for a road. Its primary job is to provide a stable, well-draining platform that prevents the top footing from mixing with the soil below.
For this crucial arena base material, FST Sand & Gravel provides the exact products recommended by agricultural engineering experts. A University of Kentucky guide on constructing high-traffic pads recommends a layer of #4 crushed stone topped with densely graded aggregate. Our 1 1/2″ Crushed Rock is the perfect equivalent for this rock layer, providing excellent structure and drainage. To top it, our Class II Base is a precisely graded aggregate that compacts into an incredibly solid, durable surface that resists rutting and provides unwavering support. Investing in the right arena base materials is a long-term investment in your arena’s performance and longevity.
The Heart of Your Arena: Selecting the Best Horse Arena Sand
The top layer of footing is where the horse and rider feel the difference. While many materials can be used, sand is the undisputed king of arena surfaces due to its durability and drainage capacity. However, as any expert will tell you, not all sand is created equal. Sourcing the wrong type can lead to a surface that is too deep, too hard, too slick, or dangerously dusty.
Particle Shape is a Game-Changer
The single most important characteristic of high-quality arena sand is its shape. Experts from Penn State Extension and other leading institutions agree that sub-angular sand is the optimal choice for equestrian footing.
- Rounded Sand (like beach or river sand) should be avoided. The smooth, ball-bearing-like particles do not interlock, creating an unstable, deep surface that can cause stress on horse tendons and ligaments.
- Sharply Angular Sand (often manufactured sand) can compact too quickly. The sharp edges fit together like puzzle pieces, leaving little room for air, which eliminates the cushion horses need.
- Sub-Angular Sand provides the perfect balance. The particles have slightly flattened edges that interlock effectively to create a stable base while maintaining small air pockets between grains that provide essential cushioning.
This is precisely why FST Arena Sand is the premier choice for professional and private facilities across Southern California. Sourced directly from our quarry, our Arena Sand is composed of hard, durable sub-angular particles that provide the ideal combination of traction and shock absorption for any discipline.
Size and Cleanliness for a Dust-Free Arena
Beyond shape, particle size and cleanliness are critical for performance and health. The ideal sand is washed to remove ultra-fine particles of silt and clay. These “fines” are the primary cause of dust—a major concern for 77% of arena users, according to one survey. Dust can cause serious respiratory issues for both horses and riders. For a low-dust arena, your sand should have between 2-5% of its material passing a #200 sieve.
FST Arena Sand is meticulously washed and screened to meet these exacting standards. This process results in a superior footing that is less prone to compaction, drains beautifully, and provides a healthier, dust-free environment for your barn.
Finishing Your Facility with Quality Materials
Different disciplines have different footing needs. Western riders often prefer a slightly faster surface, while dressage requires a firm, supportive base, and jumpers need excellent cushioning. The depth of the sand is also key; most experts recommend a footing depth of 2-4 inches to prevent the surface from becoming too deep.
Beyond the arena itself, FST Sand & Gravel has the materials to perfect your entire facility. Our Decomposed Granite (DG) creates attractive, durable pathways between barns and arenas. For effective drainage solutions around the arena perimeter or in wash racks, our 3/8″ Pea Gravel is an excellent choice.
