Dewatering trenches

EN ISO rules and regulations describe the filtration process as the process used for "retaining the soil particles which are subjected to hydrodynamic forces and allowing the passage of fluids inside the geo-textile fabric."
The characteristic opening of Tessilbrenta Geotextiles is indeed designed to retain these particles while letting the water to flow freely.
Should this not happen, the migration of the soil could reduce the construction overall load-carrying capacity.
Tessilbrenta Geotextiles have taken the place of the common gravel draining filter media in draining cuttings along river banks, in artificial lakes, in foundation walls, and in sports facilities. Tessilbrenta products have been designed in order to allow fluids to flow into draining systems, such as finely drilled piping, and at the same time to retain the finest particles so as to prevent their migration inside the drainage.

Tessilbrenta Geotextile products have the following characteristics:
- The filter fabric openings must be small enough to prevent excessive migration of soil
- They are waterproof and allow the fluid to pass through while keeping its flow constant
- They present a considerable number of openings, thus preventing obstruction - They are chemically and physically resistant, which prevent the products from suffering any damages during their laying into place.

The advantages connected to the use of Tessilbrenta geotextile products are the following:
- A continuous filtering process
- Reduced excavation
- Lesser influences on the environment
- Reduction in building time
- Reduction in the quantities of building materials required.
