DYNAMIC INCLUSION FOR STRUCTURAL CONCRETE SLABS

DYNAVOID is designed to be used under structural concrete slabs to prevent heaving caused by the upward movement of underlying ground. It is manufactured from inert closed-cell expanded polystyrene, and is not affected by moisture.

INSTALLATION INSTRUCTIONS DYNAVOID panels are laid on prepared, level ground, with joints tight. The panels are easily cut to fit around protuberances, column bases, etc. Overlay materials (hardboard, fiberboard, OSB) are strongly recommended to distribute point loads, rebar chars, etc.

DYNAVOID is available in both 100 mm (4”) and 150 mm (6”) thicknesses in order to meet the protective void requirements for virtually all structural slabs. The green portion of each column indicates the recommended performance range for each DYNAVOID type that will safely support a structural slab, while permitting void form creep and collapse to occur as a result of sustained sub-grade swell. Product selection is based on simple slab weight, producing a pressure of 23.6 kPa per metre thickness. EG: a 750 mm slab will produce .75 X 23.6 = 17.7 kPa pressure. For slab thickness measured in inches, multiply inches by 0.6 to obtain slab load in kPa.
