Problems

Poor soil conditions, drainage issues, plant stress after installation, irrigation inefficiencies, and difficulty securing long-term landscape performance.

Solutions

Better plant establishment, healthier soils, improved water balance, lower maintenance pressure, and outdoor projects that remain more stable and resilient over time.

Hydrostatic pressure & dampness

We were experiencing rising damp and a constant feeling of dampness around the house. Installing GEPS was quick and had no impact on the existing infrastructure. Since then, the ground has been stable and we no longer have any dampness, even after heavy rain.

Hydrostatic pressure & dampness

Before GEPS, our basement was regularly flooded, and the persistent dampness made the air unhealthy. Since the installation, the basement is perfectly dry all year round, without maintenance, and the results have remained stable almost ten years later.

Hydrostatic pressure & dampness

We had significant water infiltration problems in our basement. After installing the GEPS system, which took only a week and required no major construction work, the problems completely disappeared. More than six years later, the system still works perfectly, even during heavy rain.

Soil nutrient depletion

A group of various trees were planted in a small orchard north of Palmer Park in 2014. All the trees had health issues and struggled to survive. We installed NEPS on 21 of the total 43 trees at the location in December 2017. We’ve observed significant/healthy growth in nearly all trees with NEPS installed, whereas trees without NEPS struggle to bloom and/or died.

Groundwater recharge

GEPS replenishes the soil naturally, reducing dependency on artificial irrigation and safeguarding the course’s future.

Urban tree stress

Decorative trees were planted in the middle of a parking lot in 2008. The trees had to be replaced in 2016 due to health issues. The newly planted trees struggled also and were planned on being replaced once again. In February 2018, NEPS were installed around these trees to promote healthier growth. Since then, the trees greatly increased their vitality and have grown like never before.

Erosion & slope instability

GEPS stabilized wet areas on our fairways, significantly enhancing firmness and reducing ground deformation.

Stormwater excess & drainage

Exlterra's GEPS transformed our waterlogged parks into vibrant, usable spaces. The system resolved standing water issues and reduced mosquito presence, making areas suitable for recreational activities.

Hydrostatic pressure & dampness

After more than six years of use, the system works perfectly. We have had no further humidity issues despite heavy rainfall, with a solution that is simple, non-invasive, and fully reliable over time.

Stormwater excess & drainage

Since installation, the ground has remained firm and free of standing water year-round, transforming previously unusable areas into reliable, maintenance-free public spaces.

Hydrostatic pressure & dampness

The GEPS system eliminated the root cause of moisture in the walls, resulting in completely dry basement rooms, without disruptive works or impact on the building’s operation.

Roads & pathways water damage

GEPS effectively eliminated standing water and has consistently met our expectations. It improved site safety, maintained stable ground conditions year-round, and delivered a direct positive impact on airport operations.

Hydrostatic pressure & dampness

The results are particularly impressive: the basement is now completely dry year-round, the air is healthier, and nearly ten years later the system continues to perform flawlessly without any maintenance.

Flood-prone land & pooling

GEPS provides a permanent, invisible balance of soil moisture. The ground remains playable in wet periods, retains sufficient moisture in dry periods, and requires no maintenance. Turf quality, root depth, and overall playability have significantly improved.

Groundwater recharge

The GEPS technology might best be described as novel and is unique in my over 40 years of experience in water resource management, including wetland design and operation. It cannot be readily compared with existing surface drainage methods that depend on pipes or channels to deliver water to holding basins. The GEPS is passive but has great capacity for water movement, taking advantage of many mechanisms and processes.

Stormwater excess & drainage

Most of the GEPS within the infiltration basin enhanced the local infiltration rate. The infiltration rates associated with two of the shallow GEPS were 7.4 – 8.6 times faster than the one associated with native soil conditions. The infiltration rate associated with the deep GEPS was 10.2 times faster than that associated with native soil conditions.

Irrigation reduction & drought

GEPS reduced water stress on turf grass during dry spells, preserving vegetation and soil health effortlessly.

Stormwater excess & drainage

GEPS turned a previously unplayable fairway into a reliable area for sports, quickly draining stormwater and maintaining soil integrity.

Urban tree stress

NEPS revitalized newly planted trees, enhancing their health and vitality. It’s a maintenance-free, energy-efficient solution.

Orchard productivity

NEPS exceeded expectations, improving tree growth and fruit quality while reducing dependency on fertilizers.

FAQ

Each project starts with a site diagnosis. We assess the issue, constraints, and objectives, then define whether GEPS®, NEPS®, or a combined approach is appropriate.

How do I know which solution is right for my situation?

Yes. GEPS® and NEPS® can be combined when a site has overlapping groundwater, stormwater or soil nutrient challenges. The approach is modular and project-specific.

Can multiple solutions be combined in one project?

Yes. Maxwell systems can be integrated into new construction or retrofitted into existing sites, depending on access, soil conditions, and project constraints.

Is this suitable for both new projects and existing sites?

Installation is designed to be as non-intrusive as possible. The exact impact depends on site conditions, but projects are planned to minimize downtime and operational disruption.

Will the installation disrupt my operations or site usage?

Some effects can be immediate, especially with water movement. Soil nutrient improvement and decontamination processes typically develop over time as the system interacts with the ground.

How long does it take to see results?

In most cases, no ongoing maintenance is required. The systems are designed for long-term passive operation once installed.

Do I need to maintain the system after installation?

Yes. GEPS® and NEPS® are designed to support sustainable land management and align with applicable environmental standards and project requirements.

Is this compatible with environmental regulations and standards?

Maxwell Earth Systems manages the full process, from initial assessment and technical planning to implementation, coordination, and follow-up.

Who manages the project from diagnosis to installation?
