Typical arena designs - conventional arenas vs. state of the art ProEquus arena systems.

Outdoor, permanent riding arena design & construction standards.
Typical design + execution of a conventional riding arena

layer »
a. Temporary sand, typically a porous local sand,
b. which sand will quickly, naturally mature into dust with use and after exposure to typical arena environment,
c. requiring frequent replacement, or the addition of expensive bandage-types of fixes to compensate for the use of an incorrect type/size/makeup of sand.
Permanent footing layer »
a. Sand, of a permanent, natural, non-porous mineral type which will not decay into dust, ever.
b. Particulates may be angular (classical equitation), subangular (Western or English Pleasure etc.) or rounded (Western roping 'n reining, cutting and barrels, etc.), or a custom blend of the above.
c. Permanent, dust-free, high-performance sand, custom-designed and blended to optimize the footing performance of your specific riding style and level.
Separating layer »
a. compacted clay (a temporary separating layer),
b. or a filter fabric/geocloth (a temporary separating layer),
c. or compacted roadbase, five minus, quarter down, etc. (a temporary separating layer),
d. more typically: a combination including several of the above strata (still a temporary but more expensive separating layer, which will inevitably fail).
Permanent Separating layer »
ProEquus® WE40 or OT40
structural perforated mat system.

[That's it, sorry if you were expecting more.]

Drainage layer »
a. several inches depth of drainage rock, riprap, RCA, or other angular stone
b. compacted to Proctor 95 level typically,
c. requiring regular replacement, as the dynamics of hoof-on-earth rapidly intermingle the:
(above) footing layer
into the (above) separating layers
and into the (below) drainage layer,
 ... and intermingles:
the (above) drainage layer
into the (below) subsoil "base" beneath it
 = a temporary drainage design/execution, which will eventually fail.
Permanent Drainage layer »
Additional Temporary Structural design features, applied to the  graded soil base »
a. Adding Structure to the Soil - in order to sustain/support the above drainage layer,
b. the graded/leveled dirt is typically compacted to Proctor 95 levels - similar to public roadway construction standards
c. which is a temporary construction which will inevitably fail, as the equine traffic dynamics force the above layers into the subsoil.
(No additonal structural
design is required for typical soil types)
The (above) typical riding arena (i) subsoil, base, (ii) drainage and (iii) separating layer design/construction requiress:
a. trainloads of drain rock and gravel and clay,
b. thousands of square feet of geocloths,
c. dozens to hundreds of hours of heavy construction equipment,
d. dozens to hundreds of hours of skilled construction equipment operators labor,
e. for outdoor arenas - additional external runoff management structures, such as French drains, sheetwater diversion trenching, infiltration or water retention structures, etc.
 = all money misspent, long before the top footing (equine performance) layer is even addressed.
The ProEquus arena systems
replace all of the typical arena
design/construction elements.

Additional features & benefits:
Not Included

(any addional arena design base/drainage or footing layer enhancements are" extra")
Additional features & benefits:
The ProEquus sytems also provides additional features which are not supported by conventional arena designs:
a. enhanced moisture retention features,
b. enhanced footing traction features for various riding styles,
c. enhanced elasticity + resiliency (to promote horse-healthy footing)
d. prevention of sand compaction (to prevent "dead spots" or over-compacted sand)
