Horse Arena Builder in Washington
Arenas, Round Pens & Indoor Facilities Built for Rain
The Washington Challenge
Washington State isn't one climate—it's many. Western Washington's nine months of persistent rain turns poorly built arenas into mud pits. The Olympic Peninsula records over 150 inches annually. Yet two hours east across the Cascades, Yakima and the Tri-Cities receive less than 10 inches per year.
The Puget Sound convergence zone dumps unexpected rain north of Seattle. Columbia Gorge winds destroy standard structures. Eastern Washington freeze-thaw cycles crack inadequate bases.
Performance Footing is your expert consultant for Washington arena construction. Whether you're building DIY, working with your own contractor, or need a turnkey solution—with additives or without—we're here to support you every step of the way.
Why Washington Arenas Fail
Most arena problems trace back to the same issues:
Inadequate drainage — Western Washington's persistent rain overwhelms basic
Mud formation —Saturated soils and improper base construction create unusable surfaces October through June
Freeze-thaw damage — Eastern Washington's temperature swings crack improperly constructed bases
Condensation problems — Indoor arenas drip constantly without proper ventilation design
Soil migration — Without proper separation layers, base materials mix with native soil and fail
A properly engineered Washington arena handles all of this. An improperly built
one becomes a seasonal frustration—or year-round mud pit.
The Performance Footing Approach
BaseCore HD Geocell Technology
Our BaseCore HD geocell system addresses Washington's toughest construction challenges:
50% less aggregate material required compared to traditional methods
3 inches of BaseCore = 12 inches of gravel in load-bearing capacity
2,000+ lbs/sq ft tensile strength with double-weld seams
75+ year durability — UV, chemical, and weather resistant
Saturated soil stability — Maintains separation layers even when completely waterlogged
Perforated design manages flash flood drainage while retaining moisture during drought
BaseCore HD cells are almost 50% smaller than others on the market, providing superior stability whether
you're dealing with Puget Sound's saturated lowlands or Spokane's harsh winters.
Footing Additives for Washington Conditions
Performance Footing offers proven additives that perform in Washington's diverse climates. Choosing an additive is optional—we support arena builds with or without them based on your goals and budget.
Consistent cushioning regardless of moisture levels—critical for Western Washington. Helps regulate water content during wet season while maintaining performance. Effective from below zero to 115°F for Eastern Washington's temperature swings.
Premium bio-based blend of polymerized rubber and fabrics. Excellent moisture management for Western Washington's persistent rain. Maintains consistency through Eastern Washington's dry summers and wet winters.
100% USDA-certified bio-based materials. Neoprene-free, allergen-free. Superior impact absorption that won't break down in constant moisture or freeze-thaw cycles.
Organic fiber blended with natural elastomers for enhanced stability. Binding properties resist displacement from Columbia Gorge winds. Ideal for jumping arenas requiring consistent shock absorption in any weather.

Arena Types We Support
Indoor Arenas
Covered Arenas
Outdoor Arenas
Round Pens
Indoor Arenas
Essential for Western Washington's nine-month wet season. Vapor barriers and insulation strategies keep surfaces safe. Common dimensions from 60x120 feet (private) to 100x200 feet or larger (commercial).
Outdoor Arenas
Year-round usability with proper drainage engineering. Multi-layered systems handle Western Washington's volume and duration. Eastern Washington designs balance drainage with moisture retention for dry summers.
Covered Arenas
Weather protection while maintaining natural airflow. Complete protection from wind-driven Pacific storms in the west. Snow load management and summer shade in the east. Gutter systems handle debris from surrounding evergreens.
Round Pens
50-60 foot diameters recommended. Posts set 2-3 feet deep for stability in saturated soils. Footing addresses the reality that Washington's native soils—whether Puget Sound clay or Eastern Washington silt—need engineering for safe, mud-free riding.
Construction Essentials
Site Prep:
Evaluate microclimate, soil saturation levels, hillside runoff patterns, and water table depth. Critical in Western Washington's wet lowlands.
Grading:
1-2% slope for drainage. Laser-guided precision essential for managing both volume and duration of Pacific Northwest rainfall.
Base Layers:
Geotextile separation (critical for preventing soil migration), BaseCore HD geocell, aggregate fill specified for your climate zone.
Footing:
Quality sand with or without additives based on your discipline, moisture exposure, and maintenance preferences.
