Thanks. For positive bond breaking, it is essential the casting slab be 100% sealed with TILT-CRETE. Visually and physically inspect the slab to witness the entire surface has a definite sheen. Any dull spots must be recoated. Questionable areas can also be tested by dropping water on the surface. If the water beads-up or forms a bubble and does not penetrate the concrete surface, it is sealed. Any areas accepting penetration of the water must be recoated until a positive seal is achieved. 55 Gallon (208.20 L) Drums. Do not under apply or over apply TILT-CRETE. If less than the recommended amount is applied, the film may not be continuous or of sufficient thickness to inhibit inter-slab moisture penetration which may result in panels sticking to the casting slab. WebMop all contact surfaces of concrete and Organic Felt or geotextile fabric with cut-back asphalt. 0000014806 00000 n Using the same type of detail as for the unreinforced wall would require the control joint to cross the vertical reinforcement, thereby preventing movement and defeating the purpose of the control joint. They are essentially vertical planes of weakness built into the wall to reduce restraint and permit longitudinal movement due to anticipated shrinkage, and are located where stress concentrations may occur. In walls containing vertical reinforcement, the cell adjacent to the opening is usually grouted and reinforced to provide solid support and additional strength for jambs. TECHNICAL DATA SHEET Sec SECTION 2 Can use cut 'sonotube ring' or better, polyurethane wrap, to provide a gap for installation, and remove it the first time it is lifted.
