It is special methods of placement of concrete slip forming can be done both for vertical construction or horizontal construction.

1. Slip Form of vertical construction is generally adopted for tallstructures.

2. In this method, concrete is continuously placed , compacted and formworks is pulled by number of hydraulic jacks, giving reaction against jack rods, or main reinforcements.

3. The rate of slipping in formwork will vary depending upon the temperature and strength development of concrete to withstand without support of formworks.

4. The horizontal slip form construction is rather a new technique in India. It is adopted for road pavement construction.
