Equestrian surfaces require 4-12% moisture to achieve natural moisture binding for shear and load bearing strength required by the horse. Stabilizer Water Binding Technology keeps your arena’s ideal moisture content window open longer. It binds water and soil particles, maintaining stability during rain and releasing moisture into the soil or sand when dry. Combined with StaLok® Fiber, which gives three dimensional strength and stability to sand and soil, the Stabilizer Arena Mix has shown increased safety, while allowing for traditional arena management methods.
