Erosion protection for land & water
Tecomatic’s erosion protection solutions play a crucial role in supporting infrastructure and preparing our society for the future.
Sustainable and effective erosion protection
Tecomatic’s concrete mattresses offer a quality-assured solution for erosion protection with a wide range of applications. Available in three different models, the choice of mattress is tailored to meet the specific conditions of each project. They perform equally well on land and in water and are available in various thicknesses weights.
Erosion protection in aquatic environments
Concrete mattresses provide a quality-assured solution for erosion control at power plants, ports, and for stabilizing and sealing canals and dams. They can also be used as a protective cover to prevent hazardous and contaminated materials from entering surrounding waters. This is particularly useful in areas such as polluted ports or factories near water, where contaminants may have been discharged.
Another application is the protection and stabilization of underwater wires and cables. The concrete mattresses secure the cables tightly to the seabed, preventing movement and reducing the risk of wear and tear.
Propeller erosion protection in ports
Concrete mattresses provide a fast and effective solution for preventing erosion caused by strong propeller currents in ports. Common applications include securing the concrete mattress to sheet piling or positioning it beneath piled quays.
When installed against sheet piling, the mattress is positioned to allow for tight sealing by casting concrete between the mattress and the sheet piling beams. For piled quays, the mattress is carefully fitted around the piles and sealed tightly to prevent propeller currents from washing out fine material. Concrete mattresses are particularly effective in the wave and swell zones, which are often found beneath quays where turbulence is created as waves and swells impact the back beam.
One key advantage of using a textile mattress under a quay is the ease of installation. The mattress can be conveniently placed under the quay and grouted with concrete afterward. In cases where material has already eroded, we can perform backfilling by injecting concrete behind the concrete mattress in a controlled manner through its filter points. This method ensures proper restoration while reducing the need for extensive dredging to achieve frame-free depth. The thin yet strong structure of the mattress makes it an efficient and durable solution for erosion protection.
Erosion protection on land or at the waterline
When installing concrete mattresses on land, it is possible to color them to blend seamlessly with the environment if aesthetics are a priority. Additionally, coconut nets can be used and sown with grass during construction, for instance. Another option is to place pre-planted vegetation mats on top of the concrete mattress. We also have reference projects where clients have laid stone on land and used concrete mattresses up to the waterline.
Protecting slopes from erosion
A common application for Tecomatic's concrete mattresses is protecting slopes that end in water from erosion. The filter point design allows water to pass through specific points, ensuring even pressure distribution across the slope. Additionally, different thicknesses can be combined, such as using a heavier mattress on the outer edge to enhance stability.
Residual shape
When repairing stone coffins, concrete mattresses can serve as both erosion protection and a retention form. Once the mold is cast, lightweight concrete can be used to backfill the voids, creating a homogeneous structure. The mold is cast to seal tightly against the substrate, allowing for controlled filling of the void behind the mattress.
Other applications
Bridge support
Installing a concrete mattress tightly around the bridge abutment or cone is an effective solution to prevent material from being washed away, thereby protecting the bridge structure from weakening.

Skanska - New Slussen
The redevelopment of the Slussen area in Stockholm has been ongoing for some time. Tecomatic is working on erosion protection in several parts of the area and in Mälardalen. One of the reasons for rebuilding Slussen is that the water level, and therefore the risk of flooding, is too high.
