The concrete composition is in accordance with the specifications mentioned below:
- Concrete composition: NBN EN 206-1: 2001
- Compressive strength class: C55/67
- Exposure classes: XC4, XS3 and XD3, XF4, XA3
- Environmental classes EE4, ES4, EA3
- Max. water – cement ratio: 0.45
- Concrete cover: 30mm
In addition, we guarantee a composition with a maximum water absorption of 5%. This way, we satisfy the strongest requirements with regard to chemical deterioration and exposure to frost and thaw.
To assure constant quality, we are equipped with a concrete mixing plant of the latest generation, which allows us to follow the whole production process thoroughly with various measures and precision sensors. Because of this, we have the possibility to change recipes efficiently, quickly respond to unexpected factors and in this way guarantee the same concrete standard and quality.
We execute tests in our concrete laboratory with regard to the compressive strength, the water absorption, the water-cement factor and granulometry.
We monitor the measurements of our elements periodically to avoid deviations. In doing so, we use the tolerances in accordance with the standards for retaining wall elements NEN EN 12258 with national addition NBN EN 15258.
