Stall Flooring- The importance of good flooring becomes more evident as a horse spends more time in his stall. The fitness of a horse's legs and feet can be greatly affected by the type of stall flooring chosen. The most suitable floor is highly dependent on management style, while personal preferences can have a strong influence. Fortunately, there are many options for suitable floors in a horse facility. The objective of this bulletin is to provide information on stall and stable flooring materials, including flooring material attributes and options for overcoming some deficiencies. Subfloor construction and drainage features are presented as these strongly influence floor integrity. The two major categories of stable flooring materials depend on whether the material is porous or impervious to wetness (Figure 1). Floor construction, from the ground up, will depend on what type of material is chosen. Porous floors will have an underlying foundation of sand and/or gravel to aid water movement down into the ground below the stable. Impervious floors may be sloped toward a drain so that urine and water can run out of the stall. Even impervious floors have a few inches of sand or fine gravel underneath for material stability and drainage of subsurface water. With either type of stall flooring, often enough bedding is used to absorb excess water and urine so actual liquid runoff is minimal except after a stall washdown.
