Outdoor, permanent riding arena design & construction standards.
This Column: Typical design + execution of a conventional, "Old School" riding arena.
Old School
Below: Design element functions of
Old School American Riding Arena Design
... i.e. Gravel + Clay + Bulldozers + Compactors + Box Scrapers + Tons of Manual Labor + Tons of Equipment Operator Costs + on + on ...
Top layer:
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.
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).
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.
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.
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 layer is even addressed.
Additional features & benefits:
No other benefits are included.

(No additonal structural
design is required for typical soil types)

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.

ProEquus® WE40™ or OT40™
structural perforated mat system laid directly on top of any firm + level base.

[That's it, that's all there is. Sorry
if you were expecting more.]
Additional features & benefits:
Other Benefits Do Include:
The ProEquus® sytems also provide additional features which are not supported by conventional "old School' 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)
