FAQ

A GEPS® installation means fewer puddles, less heat, and therefore better usability of public spaces.

A GEPS® system is guaranteed for 10 years, and its effectiveness has been proven over several decades.

A GEPS® system requires no maintenance throughout its entire lifespan. Only visual monitoring of the embankment is recommended.

A traditional website is a static layer. SiteWorks OS is operational: it captures leads, manages data, automates workflows, and supports ongoing marketing and growth.

Absolutely. Every GEPS® installation is designed to withstand agricultural or municipal traffic on light roads, as well as road and highway traffic. GEPS® can even handle rail traffic.

Both. Solutions can be integrated during construction or retrofitted into existing environments, depending on access and constraints.

By its very nature, GEPS® greatly reduces the volumes discharged, which proportionally decreases the frequency of cleaning.

Depending on the nature of the terrain, GEPS® is installed 50 to 60 cm (20 in. to 23 in.) below the ground surface, below the frost zone.

Due to its non-polar nature, the material GEPS® is made of has an exceptionally high resistance to chemicals and other media. It is not affected by aqueous solutions of salts, acids and alkalis, and thus has no negative impact on the environment; it does not to produce harmful emissions, and requires no energy consumption.

Each project starts with a diagnosis of your site conditions, constraints, and objectives. Based on that, we determine which solution—or combination—fits best.

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® does not replace compensation, but it helps limit the scale and frequency of the claims that lead to them. Insurers see it as a concrete tool to contain the explosion of costs linked to the shrink-swell phenomenon in clay-rich soils, and recurring floods.

GEPS® eliminates moisture by reducing hydrostatic pressure against walls and foundations, thus making cellars dry.

GEPS® follows this same approach: a natural and controlled regulation of soil flows, applied here to sustainably stabilize the water balance around homes.

GEPS® guarantees dry and usable access after rain, with less mud and less maintenance required, and less risk of costly damage.

GEPS® has a positive impact on your property value because a property without moisture in the foundations or cracks in the walls sells better.

GEPS® improves water availability in the soil depth, reducing water stress and promoting plant vigor.

GEPS® is a fully passive underground system that requires no dredging, energy, or pumping. Once installed, it incurs no operating costs and requires no maintenance.

GEPS® is installed in a non-invasive and clean manner in a few days to a few weeks depending on the type of terrain and ease of access.

GEPS® is installed non-invasively in 2 to 10 days, depending on the type of access and terrain.

GEPS® is not a drainage system, but an innovative device that transforms the soil's capacity to manage water. Its preventative and sustainable action makes it a credible solution for integrating a prevention policy into insurance risk management.

GEPS® reduces runoff and network overload, thus significantly improving urban comfort.

GEPS® will guarantee you dry basements, reduced pumping costs, reduced damage related to water and soil movement, and increased property value.

In most cases, no, because GEPS® is a passive, buried installation that is not connected to the grid. If you have any doubts, we can verify this for you before installation.

In the event of prolonged drought, and within the limits of nature, GEPS® retains residual moisture deep down and dynamically brings it up to the surface to hydrate from below, limiting the impact of the lack of water on soils and crops.

Installation is designed to be as non-intrusive as possible. The level of disruption depends on the site, but most projects are planned to minimize downtime.

NEPS® can be installed by trained professionals such as arborists, landscape contractors, and specialized installation teams.

NEPS® is an underground passive system that transfers natural nutrient-rich gases from deeper soil layers into the root zone of trees and woody plants.

NSPS® is an underground passive soil remediation system designed to neutralize chemical and radioactive contamination directly in the ground.

NSPS® is intended for contaminated soils, including chemical pollution and radioactive contamination, depending on site conditions and treatment design.

NSPS® is relevant for environmental agencies, industrial operators, mining and energy companies, and remediation specialists managing contaminated land.

No ongoing maintenance is required in most cases. The systems are passive and designed to function long-term without intervention.

No, a GEPS® system integrates completely into the ground without altering its surface or slopes in any way. You won't see it once installed, and its installation doesn't require turning over the ground or leaving any trace.

No, a GEPS® system only acts on the physical management of water, without chemical interaction.

No, because unlike traditional drainage, GEPS® is not a tube that conducts water or anything: it aerates the soil and makes it dynamic and responsive to pressure changes, acting like blotting paper, and allows water to circulate in the soil naturally by differential pressure.

No, once installed the GEPS® system is 100% passive, requiring neither energy nor maintenance to operate at its full potential.

No, once installed, GEPS® consumes no energy and requires no consumables or spare parts. It also requires no maintenance.

No, the GEPS® system is completely buried underground and invisible on the surface.

No, the roots bypass the GEPS® device exactly as they do with stones and other natural obstacles.

No. GEPS® is designed to work with the natural soil structure, not against it.

Installation is minimally invasive: small-diameter perforations, no large-scale excavation, no heavy material displacement. The system operates underground, preserving the surface, vegetation, and existing landscaping.

Functionally, it improves natural water infiltration and maintains oxygen levels in the soil. That matters. Traditional drainage often evacuates water away from the site; GEPS® redistributes it within the ground, supporting soil stability and biological activity instead of disrupting it. No chemicals, no artificial layers, no visible infrastructure once installed. It’s a structural intervention, but a discreet one.

No. GEPS® is not traditional drainage, nor is it a vertical drainage system. GEPS® profiles are not drainage pipes: they do not draw in, collect, or discharge rainwater. Their role is to aerate the soil deeply and restore its ideal structure and natural function so that it acts like a sponge. The water then distributes itself naturally, circulating in the subsoil without pumping, forced drainage, or discharge to the outside.

No. It solves a different problem.

Riprap and retaining walls are mechanical solutions. They hold soil in place or resist lateral pressure. They treat the symptom: movement or erosion already happening.

GEPS® addresses the cause: water imbalance in the soil. Excess moisture, poor infiltration, pressure buildup. By stabilizing how water moves through the ground, it reduces the conditions that lead to erosion, swelling, or structural stress.

In some cases, this can reduce the need for heavy structures. In others, it complements them by improving long-term performance. But it doesn’t replace load-bearing or structural retaining systems. It operates upstream of those constraints.

No. NEPS® does not inject fertilizer. It passively restores access to natural nutrients already present in deeper soil layers.

No. NEPS® is a passive underground system with no pumps, no external inputs, and no routine maintenance requirements.

No. NSPS® is designed for in-situ remediation, which means contaminated soil can be treated in place without excavation and transport in many cases.

No. SiteWorks OS is designed to replace fragmented tools by centralizing core functions in a single environment, reducing complexity and integration issues.

None, GEPS® is a completely passive and maintenance-free system.

Not always. The right remediation strategy depends on the site, the contaminant profile, regulatory requirements, and the required treatment outcome.

Of course, GEPS® is ideal for securing the space and reducing puddles after rain.

Once installed, the GEPS® system is invisible and remains active for decades without maintenance. It is a unique investment that provides long-term protection for buildings and reduces the risk of long-term claims.

Shrink–swell is the volume change that occurs as a result of changes in the moisture content of clay-rich soils. Swelling pressures can cause heave, or lifting of structures, whilst shrinkage can cause settlement or subsidence, which may be differential. This phenomenon is one of the main sources of building damage in many regions. GEPS® aerates and homogenizes the soil, which reduces the differential movements responsible for cracks. Buildings are better protected, and shrink-swell-related claims decrease.

SiteWorks OS is a complete digital infrastructure for running and growing a business online. It combines website, CRM, automation, content, and marketing tools into one integrated system.

Some effects are immediate, such as improved drainage. Others stabilize over time as the system interacts with the soil and environment.

The difference is fundamental, both in principle and in terms of maintenance, durability, and efficiency. Drainage collects and removes water—and requires maintenance—whereas the GEPS® system infiltrates and regulates moisture deep down, without maintenance.

The installation cost of GEPS® varies depending on the area, perimeter, and nature of the terrain, but generally it remains very competitive compared to the installation of a conventional drainage system combined with an irrigation system—because it replaces both.

The length of GEPS® units varies between 1.5 and 12 m (5 to 20 ft) depending on the project design: they are supplied and sized to penetrate the usable layer of soil to the chosen depth and are custom-adapted during the installation plan.

The materials used in the design of GEPS® profiles are chemically stable and environmentally neutral, designed to last for decades without any maintenance.

The return on investment of GEPS® is variable, but generally quick thanks to the absence of maintenance, reduced water consumption, increased property value, and reduced damage and losses.

The system is built to evolve. New features, pages, automations, or integrations can be added without rebuilding from scratch.

There are no maintenance costs: GEPS® is a passive system, without pumps or mechanical parts.

Ultrabrand builds and maintains the system. Updates, improvements, and optimizations are handled continuously as part of the ongoing collaboration.
