Modified-Bitumen Membrane (4mm Thickness)

Test Report:

General Application Steps:

1. Clean and prime the substrate to properly receive a new, two-ply waterproofing membrane. Make sure the primer is completely dry before application.
2. The movement of the torch should be a continuous to and from motion allowing the flame to cover the entire width of the membrane without burning the side of the adjacent sheet already installed.
3. Heat concrete substrate when it’s cold. Verify that all roof openings, curbs, pipes, sleeves, ducts, vents, valley, ridges, box gutters, dormers, hips, eaves, rain water outlets, chimney, expansion joints or other penetrations through the roof are solidly set, and that all flashings are properly sealed.
4. Side laps must be 10 cm and end lap joints must be at least 15 cm. The overlapping lines of base sheets at side lap joints serve as a guide for proper side overlapping.
5. End laps are areas of possible infiltration of water due to an excessive thickness of membrane causing a void. After aligning end lap, perform a 45° angle cut at on all the end laps of the underlying sheet. Once the 45° angle cut is performed it will provide a smooth tapered transition. An asphaltic bleed out must be achieved at this transition location and at all the “T” joints formed by the succeeding courses.
6. To prevent overly thick membranes, stagger the end laps a minimum of 30 cm relative to those of the base sheet.
7. Use a geotextile as a separation layer prior to the application of the asphalt.

Note:

-Rain, frost, snow and high humidity can interfere with the adhesion of the membrane. With temperatures below +2°C it is better to avoid the application.

-Before application the substrate must be clean and dry. Standing water should be removed from the deck surface before recommencing laying operations. Special care is required during installation to avoid damage to waterproofing membranes.

-If it is impossible to restrict access to the waterproofing professionals alone, temporary protection must be employed to protect the membrane from the level of traffic.
