Precast concrete elements offer many advantages, such as an excellent finish quality, thanks to their production in a controlled industrial environment (temperature, formulation, setting, molding, etc.).

They also provide greater control over jobsite operations, as they are not manufactured on site and do not depend on a concrete plant. Time savings are also significant, since prefabricated solutions require no concrete setting time and can be implemented at high production rates. Not to mention that they require less excavation work and less manpower.

Finally, they can be used in a wide range of applications: 

Retaining walls


Foundations for homes



Civil works
