Basic principles of the scaffolding foundation
The scaffolding must be erected on the ground showing the proper load-bearing capacity. Therefore, we always mount them on a stable, well-tested surface. It is profiled with an appropriate slope, which ensures free drainage of rainwater during heavy rains. The weight should be evenly distributed, which is possible thanks to the use of special wooden bases. Their task is to increase stability of the whole scaffold. We never use stones as a base as this increases the risk of cracking. When installing screw jacks, we always use a central position. As for the thickness of the base, it should be as large as possible. A 4.5 cm thick underlay is recommended. This ensures a better load distribution. If we want to transfer the load at an angle of 45 ° in relation to the wooden base contour, use one that is stiffer than the ground.
Inclined foundation It is not uncommon for the scaffolding foundation to be inclined. We then have to level them properly. For this purpose, several solutions are used, among them: tilting screw jacks, leveling plates or appropriately adapted wedges. The pipes are screwed to the screw base. Thanks to this, we avoid the risk of bending of the tilting screw base. Additionally, the wedge must be secured against slipping. However, if we do not use an appropriate wooden base, the vertical anchors will have an unacceptable load. As a consequence, the stability of the structure will be disturbed. You should also know that in such a situation the pressure on the ground decreases down to approx. 20% .
In some cases, pipes are also used to stiffen the feet. It happens when we have to install the unscrewing of the stands and it is relatively large. This action is to increase the load capacity.
