Bank protection of the Asha River using concrete-filled mats

At the site of major repairs on the Asha – Kropachevo road, there was a risk of erosion of the flooded slope at the river constriction. Bank protection was required to ensure durability and resistance to floods.

The primary solution selected was concrete-filled mats «ТехПолимер». These are geotextile containers with a fixation system that form a strong protective monolith after being filled with an injection mixture.

Technology operating principle

1. Mat installation: The mats are placed on the slope, precisely following its contours.

2. Filling with the mixture: Concrete grout is pumped into the mats under pressure.

3. Structure formation: Excess water and air are discharged through the pores of the geotextile, ensuring dense and rapid concrete hardening.

• Cost savings: Unit cost per m² is lower than that of gabion structures.

• Speed: Minimal labour requirements and logistics.

• Reliability: Resistance to erosion and flooding.

• Aesthetics: Neat appearance that preserves the natural landscape.

Concrete-filled mat technology is a fast and cost-effective solution for protecting shorelines of any complexity.
