Geotextiles for creating artificial reservoirs and ponds. Their importance and advantages.

Artificial ponds and reservoirs are a wonderful addition to landscape design, but their creation requires special attention to detail, including the selection of appropriate materials.

In this article, we'll explore the role of geotextiles in these types of projects and discuss their importance, use, and benefits.

Geotextile is an innovative material widely used in many areas of construction and landscape design. Its use in the construction of a pond or reservoir is an essential element, ensuring its functionality and durability. It is an integral part of the foundation and is used as a protective layer for the waterproofing layer (PVC, butyl rubber film, or liquid rubber) against penetration by rocks, tree roots, and other uneven surfaces.

Due to its unique properties, the use of geotextiles entails many advantages:

1. Debris protection: Geotextiles are laid on the bottom of a pond before filling it with water. They create a barrier that prevents debris, sand, or soil from entering the water. This helps maintain the water's cleanliness and clarity, preventing unwanted sediment and pollution.

2. Plant protection: Geotextiles can be used to prevent plants from growing from the pond bottom. They act as a barrier to plant roots and seeds, helping to maintain the desired aesthetics and cleanliness of the water surface.

3. Erosion Protection: Artificial ponds and reservoirs are susceptible to erosion, especially from wind and water currents. Geotextiles provide effective erosion control. They help retain soil and prevent it from washing away, ensuring the stability of the artificial pond or reservoir.

4. Drainage Improvement: Geotextiles improve drainage. They promote the drainage of excess moisture, preventing water accumulation and potential problems such as rotting and odors.

Needle-punched geotextiles are the most popular choice for creating artificial reservoirs and ponds. The choice of density depends on the specific project conditions and requirements, but geotextiles with a density of 200 g/m² or more are generally recommended. This type of geotextile is quite flexible, making it easy to install and providing more effective filtration. When laying geotextiles, it is important to ensure that the sheets overlap by 15-30 cm.

Thus, geotextiles used in pond construction will provide reliable protection for the waterproofing layer, help preserve the beauty of your pond, and ensure its longevity.
