FAQ

The GEPS® system is a technology developed and patented by Exlterra, an American company specializing in advanced soil remediation and regulation solutions. Exlterra technologies are used to address complex problems in demanding environments, including water management, the neutralization of chemical and radioactive pollutants, and the improvement of soil nutrients.

GEPS® lines are usually spaced between 3 and 6 feet apart. Final spacing depends on soil permeability, compaction levels, and drainage objectives.

A standard football field installation typically takes between 2 and 5 working days, depending on site access, soil conditions, and project scope.

Most fields can return to use within days after installation. Full recovery time depends on turf type, season, and post-installation maintenance practices.

Yes. GEPS® is installed with minimal surface disruption and does not require full turf removal or field reconstruction.

GEPS® is particularly effective in compacted and clay-heavy soils, where it improves porosity, water movement, and oxygen exchange.

Yes. GEPS® works with sand-based profiles by stabilizing moisture distribution and preventing localized dry or saturated zones.

GEPS® complements or reduces reliance on traditional drainage systems. In many cases, it improves performance without full pipe replacement.

GEPS® reduces the frequency and intensity of mechanical aeration by addressing compaction at the subsurface level.

GEPS® requires no active maintenance. Standard turf management practices continue as usual.

GEPS® is designed as a long-term solution and remains effective for many years when installed correctly and paired with proper turf management.

Yes. GEPS® can be adapted to sloped and uneven surfaces with appropriate layout and flow management.

Fields treated with GEPS® often require less frequent watering while maintaining consistent moisture levels in the root zone.

Excess water is dispersed and evacuated through the soil profile, reducing surface accumulation and saturation.

Sites with severe subsurface obstructions or inaccessible soil profiles may require additional evaluation before installation.

GEPS® is typically installed 2 feet below the surface, with GEPS® boosters being 2 to 15 inches under the surface depending on soil structure, root zone depth, and performance requirements.

Traditional drainage focuses on evacuating excess water as fast as possible through pipes or gravel layers. GEPS® works within the soil itself, improving rainwater absorption, lateral water movement, and long-term soil structure rather than just removing water.

GEPS® creates a structured underground network that improves porosity, reduces compaction, and stabilizes water flow. This enables consistent drainage during heavy rain while retaining usable moisture during dry periods.

No. GEPS® is a complete water and soil management system. It combines drainage, flood management, soil remediation, and ecological soil management into one integrated solution.

By regulating water and oxygen in the root zone, GEPS® promotes deeper root growth, stronger turf density, faster recovery, and more consistent playing conditions.

Yes. GEPS® significantly reduces surface water accumulation by increasing infiltration rates and directing excess water away from the playing surface before it becomes a problem.

During heavy rain, GEPS® manages excess water through controlled subsurface dispersion and evacuation, preventing saturation, puddling, and match cancellations.

Yes. GEPS® directly addresses soil compaction by restoring soil structure and air exchange, reducing the need for aggressive mechanical aeration over time.

GEPS® improves water retention balance, which often reduces watering frequency. Fields dry faster after rain but retain sufficient moisture for turf health, optimizing irrigation efficiency.

Yes. GEPS® integrates seamlessly with existing water spraying and irrigation systems and often enhances their effectiveness by improving soil water distribution.

GEPS® is designed for performance fields such as golf greens, football fields, stadiums, and multi-sport complexes where consistent surface quality and playability are critical.

Golf greens require precise moisture control. GEPS® stabilizes water levels in the root zone, reducing soft spots, dry patches, and disease pressure while improving green speed consistency.

Stadium fields experience intense use and weather exposure. GEPS® maintains stable playing conditions, accelerates recovery, and reduces downtime between events.

GEPS® is optimized for natural turf systems. It supports ecological soil function, which is essential for healthy natural grass surfaces.

Yes. GEPS® improves biological activity in the soil by restoring air, water, and microbial balance, contributing to long-term soil regeneration.

GEPS® is a long-term infrastructure solution. When properly installed, it delivers durable performance benefits for many years with minimal degradation.

Yes. Your GEPS® system requires no maintenance. In addition, improved drainage and soil health reduce emergency repairs, surface treatment, and excessive aeration, thus lowering overall turf maintenance costs.

GEPS® installation is precise and controlled. Fields are restored quickly, and disruption is minimized compared to full reconstruction or traditional drainage replacement.

Sam Gash brings a performance-first mindset rooted in elite sports. His approach prioritizes precision, measurable outcomes, and long-term field performance, not short-term fixes.

Every project starts with a field assessment analyzing soil structure, drainage behavior, usage patterns, and performance goals to ensure the GEPS® configuration is tailored to the field.

GEPS® is a subsurface water management and soil remediation system designed for performance fields. It addresses poor drainage, surface flooding, soil compaction, and declining turf health by restoring controlled water movement and oxygen exchange within the soil profile.
