Each water body requires solutions that are not only functional, but also precisely tailored to the specifics of the site. In this case, the challenge was to rehabilitate a 600 m² recreational pond. The slopes, with a 1:1.5 slope, posed a risk of erosion, and sliding aggregate could threaten the stability of the entire structure and compromise its integrity.

Who was the customer?
The client was an individual investor who undertook the rehabilitation and protection of an existing recreational pond. His goal was to restore the full functionality of the pond and create a structure that is durable, safe and aesthetically pleasing, maintaining full watertightness and resistance to the effects of time. He paid special attention to protecting the layers already in place, namely the EPDM membrane and geotextile, which determined the tightness of the entire structure.
The investor expected a solution that would ensure slope stability, erosion resistance and long-term reliability. He turned to Geo Globe Poland to benefit from proven solutions and experience guaranteeing high quality implementation.

What problem did the customer face?
The key question was: How to protect the slope of the pond without disturbing the sealing layer?
The steep 1:1.5 slope required a detailed design approach, as any aggregate landslide could lead to destabilization of the entire structure. An additional challenge was the presence of existing layers: a 1.17 mm thick EPDM membrane, responsible for the tank's watertightness, and a 300 g/m² geotextile fabric, acting as a separation and filtration barrier and protecting the seal from the penetration of soil particles.In such a situation, there was no room for compromise. Even the slightest breach of the EPDM layer could have resulted in the need for costly repairs and loss of full functionality of the pond.
Solution designed by Geo Globe Poland
In order to meet the requirements of this project, it was necessary to use a system that would simultaneously provide slope stability and protect the existing seal layers. The choice fell on cellular geonets Geomaxx® GKS-33007560TPC with a height of 7.5 cm in the "small cell" variant. This solution made it possible to effectively stabilize the aggregate even at a slope of 1:1.5, guaranteeing the resistance of slopes to erosion.
The method of installation was also crucial. We used a dedicated anchoring system, which was designed to keep the delicate EPDM membrane intact and keep the tank fully sealed. Complementing the entire system were polypropylene lines, which acted as additional ballasting and stabilization. Although they are often overlooked in construction, in this case they proved to be an essential element for the long-term reliability of the structure.
Logistics also played an important role. Thanks to the high inventory maintained at Geo Globe Poland, the investor received all materials from us without delay, which made it possible to start work immediately and eliminate the risk of delays.
The end result - what did the customer gain?
- The slopes of the pond have been permanently stabilized and the aggregate protected from erosion.
- The EPDM diaphragm remained intact, ensuring that the tank was fully sealed.
- The structure has gained an aesthetically pleasing and robust character, resistant to water and weathering.
- Thanks to the fast delivery of materials and a refined system, the investor received a solution that gives the assurance of trouble-free use of the pond for many years.
This case study shows that properly selected engineering solutions can effectively secure a water reservoir and ensure its reliable operation for years to come. At Geo Globe Poland, we combine technology, experience and efficient logistics to deliver projects in a sustainable and safe manner.
