In structures with stem wall construction, interior floating floor slabs experience outward pressures that follow the vertical movement of the foundation walls. This results in random, sporadic floor heave cracks. The construction joint of the interior floating floor slab, located next to the interior...
For instance, in the application to a slab, water should not be introduced simultaneously to both the top of the slab and the bottom of the slab; if it were so introduced, there would be too much risk that the cement hydrating at or near the top and bottom surfaces would seal against ...
