Innovative Strategies for Erosion Control in Linear Projects and Natural Slopes

The fight against soil erosion has led civil engineering to explore innovative solutions such as erosion control blankets. In the blog, we will take a tour of different materials and examine key strategies for erosion control, taking into account slope as a determining factor.

 

1. Impertex:

We start with Impertex, a composite textile, made up of a woven polyester geotextile and impregnated with copolymer. This material exhibits impermeability and high mechanical and weather durability properties. Its greatest application is in the coating of water flow control structures such as reservoirs, irrigation channels and crest ditches, as well as large covers and parasols to protect against rain and sun.

 

2. Biotex: Temporary blanket for erosion control for moderate slopes

Moving towards solutions to control erosion agents, we have temporary layers. Biotex is presented as an open-weave blanket with slow photodegradation, designed to protect exposed soils in areas with slopes up to 1:1 (approximately 45 degrees). Its mesh-shaped structure with textured transverse threads favors the transport of moisture by capillarity and plant growth. Biotex is an effective ally for erosion control on fill slopes and embankments.

 

 

 

3. Terratrac: Permanent blankets for erosion control for steep slopes

Focusing on steeper slopes, Terratrac emerges as a permanent blanket, durable in the long term outdoors. Its three-dimensional mesh structure provides a porous medium that retains soil particles and allows the passage of vegetation. Due to its high tensile strength, durability against aggressive natural environments and UV resistance, it is a solid choice that is offered in TRM-15 and TRM-50 versions depending on the slope. The Terratrac proves its effectiveness on cut slopes, embankments and channel lining.

 

 

4. Geomat: Detritus Fall Control

For rocky slopes where vegetation cover is not achieved and the release of debris due to precipitation or wind action is a concern, the Geoestera hydrogrid stands out as a retention element thanks to its high resistance and opening size. The geomat hydrogrid has reinforced nodes and a greater impregnation coating that gives it great durability against the elements.

 

5. Conficell: Erosion control and revegetation by confinement and root support

We entered the domain of soil protection with Conficell EC, a weather-resistant geocomposite that offers soil confinement and root support, creating stable organic layers. This is achieved thanks to the combination of a geocell and a biaxial geogrid in its lower plane, which when assembled allows to achieve a panel that is easy to open and fix to the ground, on which the fill soil is placed, ideal for the regeneration of degraded areas.

 

 

6. Geobrick: Portable geocontainer for soil confinement

We conclude our exploration with the Geobrick, a durable, weather-resistant geocontainer of rectangular shape and portable size, ideal for prefabrication and transportation to the construction site in the construction of small canal channeling works on land, bank enhancement and protection of river banks. sewers.

 

 

This review of erosion control solutions shows a portfolio of alternatives suitable for each case depending on the slope and specific terrain conditions and reveals the importance of their versatility. Civil engineering, supported by these innovative alternatives, continues to be a tireless advocate for soil and environmental preservation.
