Description
Characteristics & Advantages
• Cold applied, self-adhesive and easy to apply
• Excellent adhesion to vertical and horizontal surfaces
• Excellent resistance to chlorides, sulphates, dilute alkalis and acids
• Good tear and puncture resistance
• Water and vapour proof
Application Area
Obaproof SA-1000 is used as a waterproofing or dampproofing membrane intended for concrete protection. It may be used for horizontal and vertical application for tanking below ground structures, subways and retaining walls.
Storage
The shelf life is 9-12 months if stored properly. Avoid excessive sunlight, UV, and heat to prevent deterioration and reduced shelf life. Long-term storage can cause compound aging, loss of adhesion, and membrane wrinkling. Do not double-stack pallets. Store Obaproof SA-1000 membranes vertically in shaded areas below 35°C to 40°C on wooden pallets, covered with thick fabric and securely tied to minimize sunlight and UV exposure. Protect from all heat sources.
Surface Preparation
Surfaces shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired with a suitable Polycrete* concrete repair mortar.
Application
Apply solvent-based bituminous primer at 4-6m²/L to a clean, smooth, and dry surface using a brush, roller, or spray, and allow it to dry. Begin installing membrane plies from the lowest points or drains, ensuring overlaps are “up” slope over “down” slope. Unroll the Obaproof SA-1000 membrane, peel off the release film, and press it onto the surface, smoothing from the centre to edges with a wooden presser to remove any entrapped surface. Then, an iron roller for strong adhesion of the bitumen compound with the base surface. Ensure side overlaps are at least 50mm and end overlaps 100mm. Protect the membrane from damage during site activities or backfilling with a tough, weatherproof asphaltic protection board or a 50mm thick cement sand screed on horizontal areas. Store membranes in loose corrugated boxes or pallets away from sharp edges to prevent damage.
Note
The application temperature should be between 5°C to 55°C. Application procedures may vary slightly depending upon site conditions.
