Controlling Concrete Pour into ICFs
A site-built EPDM extension tube provides extra control at the business end of a concrete pump truck pipe.
Controlling the concrete coming out of the pump discharge tube is a challenge especially when pouring narrow core forms. For a little extra control I make a flexible tube out of a 2 ft. square piece of left-over EPDM rolled around the pump truck’s discharge pipe and held in place with a heavy duty pipe clamp.
The EPDM tube can be flexed to center on the ICFs and squeezed into an oblong shape to better match the width of the forms. And by pinching off the end of the tube you can temporarily shut off the concrete flow when moving the pipe from one area of the forms to another without creating a mess.
