CONSTRUCTION METHODS - Slipform & Jumpform

Concrete chimneys are built using one of two available forming methods, slipform and jumpform. 

Slipform construction is well suited to chimneys that are very tall or have very large diameters, and on projects with accelerated schedules. With this method, concrete is poured continuously into a single form that is steadily elevated (or slipped) to create the concrete column. An integrated hydraulic jacking system raises the formwork, controls the shell taper and wall thickness, and uses lasers to constantly monitor alignment. The slipform method is labor intensive, with work performed on an around-the-clock basis.

Jumpform construction relies on more traditional concrete forming techniques to build the shell on an incremental basis. Dominion Industry uses state-of-the-art technology to make our jumpform system an extremely efficient construction method.
