How can we get proper consolidation of a concrete slab placed on a slope without the use of a paver?
The mix should not be too stiff. A stiff mix placed by hand to the full thickness without thorough vibration usually has a lot of honey combing on the bottom, especially if the slab is reinforced. The consistency should not be less than a 2'k-inch slump, which is stiff enough to stay on most slopes. After the concrete has been spread it should be vibrated systematically and thoroughly. The vibrator should be used just ahead of a weighted, steelfaced nonvibrating slipform screed that moves up the slope. The concrete that moves down the slope behind the vibrator should be picked up and placed where it is needed. All finishing operations should proceed in an upward direction.
