The centrifugal application of Mainstay® restoration mortars to horizontal pipes is made possible by the use of the Madewell® Horizontal Mortar Spinner & Precision Cable Puller. This machine provides a simple and efficient solution to lining horizontal pipes without the need for entry. The Madewell Horizontal Mortar Spinner & Precision Cable Puller centrifugally applies mortar to any thickness from 1/2” to 2” or more by controlling the retraction speed of the mortar spinner in relation to the pumping rate of the mortar.

Features & Benefits:

  • Man inside a concrete culvert pipeProvides a solution to lining horizontal pipes without the need for entry
  • Applies Mainstay mortars evenly at the intended thickness
  • Pulls heavy loads horizontally
  • Able to retract long lengths (as much as several hundred feet) of mortar hose along with the centrifugal mortar applicator
  • Speed is precisely controlled, sometimes at speeds of only a few inches a minute for large diameter pipes and thick mortar linings.
  • The spinner air motor is constantly moving back and forth, up and down the pipe being lined for more uniform mortar application thickness.
  • The spinner sled is easily adjusted to any pipe diameter using four 1” diameter steel pipes. These are available prefabricated to any diameter pipe or can be fabricated in the field from pipe purchased from a hardware or building supply store.
