Description Aqua-Bloc® QS is an elastomeric, liquid applied, emulsified asphalt membrane designed for waterproofing foundation walls and other structures. Complies with and exceeds the requirements of CAN/CGSB 37.1M. Features -Seamless low modulas elastomeric membrane. -Retains flexibility over a wide temperature range. -Excellent adhesion to most construction surfaces such as concrete, stone, wood and metal. -Can be applied to damp or green concrete. -Bridges cracks. -Contains no solvent and is environmentally friendly. -Can be applied in one coat with setting agent to achieve immediate set through. Uses Used for damproofing and for waterproofing poured and block foundation walls, footings, split slab floors, parking garage decks and retaining walls for residential construction. Limitations Not designed to perform as a permanently exposed surface. Must be protected from damage during construction. Do not apply to excessively wet surfaces. All asphalt emulsions contain a certain amount of asphalt particles requiring that the contractor establish a suitable screening technique for spray applications.

Form tie holes must be filled with cementitious material or asphaltic roofing cement and allowed to cure. Concrete surfaces should be free of excessive fins, voids or spalled areas. Refer to Guide Specification. Cracks up to 1/8" in width: Apply Aqua-Bloc® SB (770-06) providing 60 mil coating. Embed 6" wide Yellow Jacket reinforcement. Cracks greater than 1/8" wide: Apply Blueskin Primer, Aquatac Primer, or Aqua-Bloc® QS without setting agent as a prime coat and allow to dry thoroughly. Install Blueskin® WP 200 Self-Adhesive Waterproofing membrane centered over crack and lapping 3” on each side of crack. Apply firm pressure to entire membrane surface to ensure full contact and bond. Cracks greater than 1/4" in width are not acceptable. Application For detailed application, refer to Guide Specification. Damproofing - Apply by brush or spray one coat of Aqua-Bloc® QS at a rate of approximately 2 gal/100ft2 and allow to dry. Waterproofing - Prepare the setting agent by dissolving Calcium Nitrate granules in water at the rate of 1lb of Calcium Nitrate for 9 lbs. of water (10% solution) following the manufacturers precautions. Apply membrane by suitable spray equipment to allow complete mixing of the asphalt emulsion and the setting agent at the spray wand tip. The setting agent should be introduced at a rate of approximately 10% to 20% of the emulsion throughput rate. Apply from the low point upward to allow released water to shed. Typically the application starts at the footing and works upward. Cured thickness to be a minimum of 1.3 mm (55 mils). Protection Board is not required on damproofing applications. Allow membrane to cure fully prior to installing protection board on waterproofing applications. Clean Up For uncured material use water and use mineral spirits for cured films.
