High-performance fields start

High-performance fields start underground

underground

All-in-one rainwater absorption, turf hydration, and soil regeneration. No pumps. No heavy works. Powered by Exlterra GEPS®.

Because the real game is played underground

High-performance fields fail for one reason: water mismanagement. Too much water suffocates roots; too little stresses turf. GEPS® restores natural soil balance instead of fighting symptoms.

This system works without pumps, energy, or ongoing maintenance. It integrates with existing drainage and irrigation infrastructure. Once installed, the ground regulates itself. Permanently.

This is why GEPS® installations by Sam Gash change the game.

Rainwater absorbed 10 times faster*

Firm and usable fields all year round*

Watering needs reduced by 50% or more*

Zero maintenance, zero energy consumption

The only underground system that does three jobs at once. And never needs maintenance.

Golf courses

Greens, fairways, tees and bunkers demand precision. GEPS® stabilizes soil moisture, improves root depth, and reduces surface stress for consistent playability, fewer closures, and healthier turf year-round.

Football & soccer fields

Football and soccer destroy weak soil long before it destroys grass. GEPS® reinforces the ground structure and keeps moisture where roots need it. Stronger turf. Faster recovery. Fewer failures during the season.

Baseball fields

Baseball fields rely on consistency across infield, outfield, and base paths. GEPS® stabilizes the soil profile, improves vertical drainage, and preserves oxygen in the root zone. The surface is firmer, more uniform; it recovers faster after rain, and needs fewer maintenance.

Sports complexes

Multiple fields mean multiplied maintenance risk and cost. The GEPS® technology standardizes underground performance across all surfaces. Less intervention, predictable conditions, long-term operational control.

Lacrosse fields

Lacrosse fields demand fast drainage and stable footing during high-speed play. GEPS® stabilizes the soil profile, improves vertical drainage, and preserves oxygen in the root zone. The surface stays firmer; it dries faster after rain and remains playable through intensive spring seasons.

Equestrian arenas

Equestrian arenas depend on stable footing that dries quickly and stays consistent under impact. GEPS® stabilizes the soil structure, improves drainage, and balances moisture. The surface is firmer, dries faster after rain, and stays safer and more reliable for training and competition.

Built for elite surfaces. Proven across disciplines.

Meet Sam Gash

Built in elite performance environments. Driven by work ethic, discipline, and precision. From professional football to high-performance fields, the standards never changed.

Problems we solve

GEPS® is also used in playgrounds, parks, landscaped areas, and infrastructure zones where standing water, compaction, or unstable soil limit usability. The mechanism remains the same. The surface changes.
