Innovative use of rollable concrete

To protect EPS structures, an alternative to traditional concrete was needed. A fresh perspective led to a surprising solution.

Concrete Canvas protects EPS structure

In various parts of this large-scale project, roads, on-ramps, and off-ramps are being elevated using lightweight EPS structures. Several of these structures are aesthetically finished with sustainable green screens on the sides. However, since the green finish does not provide sufficient protection for the EPS against UV exposure, fire, and vandalism, an additional solution was sought to safeguard the material.

THE SOLUTION: CONCRETE ON A ROLL

Several options—including geotextile and precast concrete walls—were considered. A geotextile solution did not provide sufficient protection. While concrete walls or precast panels would have protected the EPS effectively, this option was ruled out due to the required height, limited space, and high costs. Joosten Concepts offered the ideal solution with Concrete Canvas, combining the best of both geotextile and concrete in one.

Lightweight, Durable, Waterproof, Fire- and UV-Resistant

Concrete Canvas (CC) provides concrete protection without the need for pouring concrete or using heavy equipment. The geotextile-encased combination of fibers and cement hardens when hydrated, forming a strong concrete layer. Once cured, the embedded fibers create a reinforced concrete mix that resists cracking and offers high-level protection. CC offers a lightweight, durable, waterproof, fire- and UV-resistant alternative to traditional concrete—with a lifespan of at least 120 years.

CC is delivered on a roll and can be easily unrolled over various surfaces and shapes, making it suitable for countless applications. Since no foundation structure, heavy transport, or large crane is needed, costs are only a fraction of those for precast concrete walls.

COLLABORATION

Over the past five years, Joosten Concepts and its partners have been responsible for the design, supply, and installation of various EPS structures, commissioned by contractor Combinatie Herepoort. Geotechnical engineering firm Kwast Consult handled the design. Joosten Concepts created the 3D installation plans and supplied all materials and systems. Contractor Bonneveld built the structures, and specialist Buitengewoon applied the Concrete Canvas.
