Nailed walls: increase the angle of repose of a slope

How are nailed walls made?

1. First, we excavate the soil from under the desired slope.
2. We then install drainage nets against the excavated slope.
3. We provide a reinforcement net on top of the drainage nets, onto which we apply shotcrete. We use the wet process for this, so that there is no need for silos to be installed on the site. Concrete mixers supply the concrete ready to pour on site. We spray the concrete against the slope using compressed air. This has the additional advantage that there is virtually no rebound.
4. We drill nails through the shotcrete.
5. After the nails have hardened, we install an anchor plate against the shotcrete.
6. If possible, we spray a second layer of shotcrete over the anchor plates.
7. In certain cases, we might first drill the anchors before installing the reinforcement nets and the shotcrete.
