3EXECUTION
3.1EXAMINATION AND PREPARATION OF SURFACES
.1Surface examination and preparation must be completed in conformance with recommendations in the SOPREMA Specifications Manual.
.2Before waterproofing work begins, the owner's representative and the membrane contractor’s foreman will inspect and approve substrate condition and ensure that related work has been properly executed. If necessary, a non-conformity notice will be issued to the contractor so that required corrections can be made. The start of themembrane application will mean that substrate conditions are acceptable for work completion.
.3Before commencing work, all surfaces must be smooth, dry, clean and free of ice and debris as per manufacturer’s recommendations.
.4No materials will be installed during rain or snowfall.
.5Concrete must be cured a minimum of fourteen (14) days and an adhesion test is recommended before membrane application.
.6Verify the compatibility of all membrane components with curing compounds, coatings or other materials which are already installed on the surfaces to be treated.
.7Any cracks over 3 mm wide should be reported to the design professional. After approval from the qualified authority, the crack should be filled in with waterproofing mastic. A 150 mm (6 inches) wide strip of membrane should be installed, centered over the crack.
3.2METHOD OF EXECUTION
.1Work shall be performed on a continuous basis as surface and weather conditions allow.
.2Adjoining surfaces shall be protected against any damage that could result from the waterproofing installation.
3.3EQUIPMENT
.1Maintain all equipment and tools in good working order.
3.4HORIZONTAL WATERPROOFING MEMBRANE INSTALLATION
.1Apply horizontal blindside waterproofing membrane loose laid on the concrete work slab or prepared and well compacted substrate.
.2Stagger laps in order to avoid excessive layering. End laps will be staggered by at least 300mm (12”). Cut a section of 100 mm (4”) at 45° angle at membrane side overlap.
.3Ensure minimum 100 mm (4”) side overlap and minimum 150 mm (6”) end lap between each strip.
.4Seal all side laps by heat-welding last 50 mm (2”) of the selvedge edge with a propane torch or using an automated electrical hot air welder.
.5Seal all end laps by heat-welding with a propane torch or using an electrical hot air welder.
.6All angle changes, inside and outside corners, as well as cold joints must be reinforced by installing an additional 300 mm (12”) reinforcement strip membraneeither fully heat-welded with a torch or self-adhesive over primed surface centered in the angle or on the joint. All membrane terminations must be sealed by heat-welding.
.7The contractor shall meticulously verify the membrane installation at the end of each day of work as well as before the steel work.
.8Holes and tears in the membrane must be repaired with a patch of waterproofing membrane either fully heat-welded with a torch or self-adhesive over primed surface. The repair must exceed the affected surface area by at least 150mm (6”). All membrane terminations must be sealed by heat-welding.
3.5HORIZONTAL PROTECTION LAYER INSTALLATION
.1Install self-adheredprotection sheetover the entire surface of the horizontal waterproofing membrane.
.2Installtheprotection sheet in a continuous longitudinal strip over the horizontal waterproofing membrane by removing the silicone release film. A minimum 25 mm (1”) overlap is recommended between each strip to facilitate installation.
.3Use a broom or a heavy roller to apply a uniform pressure over the entire surface of theprotection sheet.
.4The contractor shall meticulouslyverify the membrane installation at the end of each day of work as well as before the steel work.
.5Holes and tears in the membrane must be repaired with a waterproofing membrane either fully heat-welded with a torch or self-adhesive over primed surface. The repair must exceed the affected surface area by at least 150mm (6”). All membrane terminations must be sealed by heat-welding.
3.6VERTICAL WATERPROOFING MEMBRANE INSTALLATION (FIRST LAYER)
.1To begin application, align the first roll of membrane to a previously drawn chalk line.
.2All inside and outside corners must be pre-stripped with a 300 mm (12 in.) wide strip of membrane centered over the corner. This membrane must be installed in direct contact with the substrate not leaving any voids under the membrane strip.
.3Weld the membrane using a propane gas torch.
.4Subsequent rolls must be installed in the same manner and should be aligned with the preceding roll with a side lap of at least 75 mm (3 in.). End laps must be overlapped at least 100 mm (4 in.) .
.5Holes and tears in the membrane must be repaired with the appropriate membrane material. The repair must exceed the affected surface area by at least 100 mm (4 in.).
.6Prior to backfilling, it is recommended to protect waterproofing system with protection boards glued with specified mastic. Backfilling should commence immediately after installation of protection boards.
.7The uppermost edge of the membrane is to be mechanically fastened to the concrete substrate using termination bars. The termination bar should surpass the top edge of the membrane.
.8Apply mastic on the top edge of termination bar to prevent water accumulation and infiltration.
.9Any waterproofing membrane left exposed after backfilling shall be protected from ultra violet and mechanical damages.
3.7VERTICAL WATERPROOFING MEMBRANE INSTALLATION (SECOND LAYER)
.1Weld the second vertical waterproofing layer on the foundation wall using a propane torch and on the footing with a propane torch. The waterproofing membrane shall be welded at least 150 mm (6 in.) on top of horizontal waterproofing layer.
.2Subsequent rolls must be installed in the same manner and should be aligned with the preceding roll with a side lap of at least 75 mm (3 in.). End laps must be overlapped at least 100 mm (4 in.).
.3Holes and tears in the membrane must be repaired with the appropriate membrane material. The repair must exceed the affected surface area by at least 100 mm (4 in.).
.4Prior to backfilling, it is recommended to protect waterproofing system with protection boards.To do so, thermofusible plastic film must be burned off to expose bitumen.
.5Backfilling should start immediately after installation of protection boards.
.6The uppermost edge of the membrane is to be mechanically fastened to the concrete substrate using termination bars. The termination bar should surpass the top edge of the membrane.
.7Apply mastic on the top edge of termination bar to prevent water accumulation and infiltration.
.8Any waterproofing membrane left exposed after backfilling shall be protected from ultra violet and mechanical damages.
3.8PROTECTION BOARDS [DRAINAGE][INSULATION]
.1Using a torch, melt the plastic film on the surface to cover.
.2Adhere the drainagepanels directly on the exposed bituminous sticky surface by applyingauniform pressure on the entire surface.Oriented the geotextile towards backfillmaterial.
.3Backfill as soon as possible after protection board installationwithin 72 hours maximum.
