Figure 115: Internal Concrete Vibrator
PRODUCT MANUAL
Standard concrete with a maximum slump of 6" [152mm] can be used to make Quad-Lock walls free of voids, especially
if internal vibration is used. Slump loss is expected over time, especially in hot weather. Water added to the mix will
decrease the strength and this should not be done. Re-dosing the mix (once) with plasticizer or water reducer is
permissible.
Building Tip: A good indication that the concrete is properly consolidated is when water from the concrete mix seeps
out from the bottom of the vertical joints.
