On Structural Concrete Construction
Topping slabs and architectural walls on structural concrete must be constructed
on drain board material to prevent:
1. Surface drying tension resulting in slab curling and displacement.
2. Trapped subsurface water.
3. Dark areas in the surface of topping slabs caused by entrapped moisture.
Entire Garden Terrace is constructed over
drain board, over water proofing, over
structure deck.
4. Positive slope of 1 percent is recommended on structural slabs
to aid drainage and to prevent entrapped moisture.
