Aqua-Bloc® 770-06 is a type of waterproofing material that is designed to replace conventional hot mop felt ply and/or pre-formed sheeting systems. It is made up of a single component and forms a heavy-duty “seamless” rubber-like, impervious membrane through solvent evaporation after being applied in a single application.
The physical properties of Aqua-Bloc® 770-06 are compliant with CAN/CGSB-37.58, and it has a black color, 65% solids by weight, and a weight of 0.94 kg/l (7.7 lbs/gal U.S.). It has a coverage of 2.5 l/m2 (6 U.S. gal/100ft2) (approx.) for 2.25 mm (90 mils) minimum wet thickness, and it can operate within a service temperature range of minus 40C to 85C. Additionally, it has 1500% elongation (ASTM D412), 85% recovery, a Shore A hardness of 35, and is resistant to mild acids, alkalis, salt, and calcium chloride solutions.
Aqua-Bloc® 770-06 is a cold-applied waterproofing material that does not require any special equipment such as kettles. It is easily transported to small or “hard to get at” applications and has excellent adhesion to most construction surfaces such as concrete, stone, wood, cement, and metal. It also retains flexibility over a wide temperature range.
This waterproofing material is suitable for above, on, and below grade installations and can be used to waterproof parking decks, tunnels, planters, mechanical rooms, reflective pools, and foundation walls. It is also an excellent compound to repair hot rubberized asphalt membranes such as 790-11. However, it is not designed to perform as a permanently exposed surface and must be protected from damage during construction.
Prior to application, all surfaces must be sound, dry, and free from grease, dirt, or other contaminants and must be reasonably smooth. The deck should be blown with compressed air, vacuumed or thoroughly swept with a soft bristle broom. Curing compounds must be removed prior to application of membrane, and joints, cracks, and wall junctions require preparation.
Application of Aqua-Bloc® 770-06 is done by using a trowel, long-handle squeegee, or suitable spray equipment to a minimum thickness of 2.25 mm (90 mils). To protect the membrane from puncture, both horizontal and vertical areas should be adequately protected from damage during construction. After curing, polystyrene insulation can be adhered to the membrane using 230-21 Rigid Insulation Adhesive. Clean up should be done with mineral spirits.
It is important to note that Aqua-Bloc® 770-06 contains flammable solvents and should be used in well-ventilated areas. Suitable fire precautions should be taken, smoking or welding should not be allowed in the working area, and it should be kept away from heat and open flame. Finally, it is harmful if swallowed.
