How do you pour concrete on a slope?

Answer 1

The area to be concreted is sectioned off is small section across and up the incline. The hardcore base is fully compacted to prevent movement. The mix is made and is put into each section and allowed to go off before removing the horizontal board at the bottom of the concreted section. In most cases an additive is used to make the mix set quicker than normal thus preventing running. In the case of large areas (i.e. sides of roads, etc.) they actually used a preset slab which is lifted into place and has expansion joins inset to cope with heat changes in the concrete.
