Sand Cushion Terrazzo System
Description: A cement matrix topping under bed with wire reinforcing, isolation sheet, and sand layer system for exterior/interior floor use. This is the best cement system.
Advantages:
Due to the under bed’s depth, wire mesh reinforcing, isolation sheeting, and sand layer, it will absorb minor substrate defects and prevent mirroring to the surface.
Thickness: 2.5″ to 3″ including a .5″ terrazzo topping.
Weight: 25-30 lbs. PSF.
Dividers:
The position of divider strips is essential to performance, serving a dual function: a control for anticipated contraction and an aesthetic enhancement in separating colors. 5 feet or less on centers. Architects should design structural inset expansion plates between areas where major movement is anticipated.
