High-performance fields start underground

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

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

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.

The GEPS advantage in simple terms

Rainwater absorbed 10 times faster*

Firm and usable pitches all year round*

Watering needs reduced by 50% or more*

Golf greens

Greens and fairways demand precision, not compromise. GEPS stabilizes soil moisture, improves root depth, and reduces surface stress. The result is consistent playability, fewer closures, healthier turf year-round.

Football pitches

Football destroys 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.

Stadiums

Stadium fields absorb extreme load, weather, and scheduling pressure. GEPS manages excess rain instantly while preserving oxygen in the root zone. Fields stay playable, resilient, and visually consistent under heavy use.

Sports complexes

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

Built for elite surfaces. Proven across disciplines.
