  Like other Flagg houses, the walls were created of stone (in this case Tennessee quartzite) and mortar using a slipform process.
- 2012, Prashant Ram, Field Study of Air Content Stability in the Slipform Paving Process:
  The objective of this study is to evaluate the impacts of vibration and consolidation of modern slipform pavers used in Wisconsin on the air-void structure and air content of portland cement concrete pavements.
- 2014, Norbert J. Delatte, Concrete Pavement Design, Construction, and Performance, →ISBN, page 307:
  On most slipform paving projects, however, small amounts of fixed-form paving or "handwork" are still necessary.
(countable) A moveable form used when setting concrete using the slipform technique.
- 1968, Water for Peace: Planning and developing water programs, page 77:
  Slipforms of various designs have been used with excellent results.
- 2003, Abraham Warszawski, Industrialized and Automated Building Systems: A Managerial Approach, →ISBN:
  The slipform is fed with concrete from a crane-carried or rail-mounted bucket.
- 2005, Mary Krumboltz Hurd, Formwork for Concrete, →ISBN, page 15-13:
  Vibration may be used ahead of the slipform, but consolidation must be completed as the concrete passes under the form.

Verb

slipform (third-person singular simple present slipforms, present participle slipforming, simple past and past participle slipformed)

To use the slipform technique when creating a concrete structure.
- 2005, Mary Krumboltz Hurd, Formwork for Concrete, →ISBN, page 15-12:
  Since most horizontal slipforming is against a fixed form support such as rock or earth, the operation is essentially a consolidating-screeding-finishing operation.
- 2012, JHA, Formwork for Concrete Structures, →ISBN, page 329:
  However, with recent developments, it is possible to slipform continuous vertical flutings and varying cross sections.
- 2013, Michael R. Adamson, A Better Way to Build: A History of the Pankow Companies, →ISBN, page 60:
  To facilitate and speed construction, Charlie Pankow chose to slipform not only the service and elevator core but also the stairwells -- a more complex operation than the slipforming of the American Cement Building.
- 2014, Ravindra Dhir, ‎Neil Henderson, Concrete in the Service of Mankind, →ISBN:
  New materials such as the by-product PFA helped attain the extra durability required and it is quite common today to slipform with concrete that has 30% replacement of cementicious material and large doses of admixtures.
