Hydrotech® Monolithic Membrane 6125®

Monolithic hot-applied rubberized asphalt

Hydrotech® Monolithic Membrane 6125®(MM6125®) is a hot-applied rubberized asphalt for use in waterproofing. Hydrotech® Monolithic Membrane 6125® is a thick, tough, flexible and self-healing membrane.

  • Hydrotech® Monolithic Membrane 6125® is ideal for a Protected Membrane Roof (PMR) Assembly.
  • Conforms to all surface irregularities and bonds tenaciously to an acceptable substrate (i.e., concrete, steel, wood, etc.) eliminating lateral migration of water.
  • Completely monolithic; no seam.
  • Typically installed at 6 mm thick in the Fabric Reinforced Assembly. This is more than three times thicker than most other waterproofing membranes. Thickness is an important benefit in that Hydrotech® Monolithic Membrane 6125® exhibits the ability to self-heal and better accommodates developing cracks in a concrete substrate.
  • Homogeneous mixture of refined asphalts, synthetic rubber and mineral inert filler.
  • Contains 40% post-consumer recycled material.
  • Has no VOC. No solvent means no on-site cure failures, no two part mixing.
  • Can be installed at temperatures as low as -18°C (provided the substrate is clean, dry and free of snow and frost).
  • Detailing is simplified, with triple protection at all critical locations.
  • Ideal for dead level installations; no slope required.
  • Developed to perform in a wet (submerged) environment.
  • Tie-ins from one day's work to the next are easy, perfect for phased construction.
  • Can only be installed by "trained" authorized applicators.

APPLICATION INSTRUCTIONS

EQUIPMENT

Hydrotech® Monolithic Membrane 6125® must be heated using a double-walled, indirectly heated melter-mixer. The melter must be equipped with thermometers and a direct-drive mechanical stirrer. Heating bitumen in a directly heated melter is strictly prohibited. The membrane temperature in the melter must be between 180 °C (minimum) and 190 °C (maximum). Take care not to exceed the maximum temperature.

SUBSTRATE PREPARATION

Concrete Substrates
Finish the concrete surface to be covered using a wooden float, ideally to a CSP surface profile between 3 and 5 to ensure the required adhesion. Fill honeycombs, voids, and surface cracks with a latex filler compatible with the waterproofing membrane. Ensure the concrete has cured for at least 14 days before applying the base coat. Sand all sharp edges of joints or changes in plane and remove any loose aggregate. The substrate must be completely free of any sealants or similar materials to a depth equal to or at least twice the joint width. For expansion joints, it is preferable to chamfer the edges. Before beginning application, clean the substrate to remove curing compounds, dust, paint, frost, formwork oils, loose particles, and other contaminants that may impair membrane adhesion. 

Crack and Joint Treatment
Bridging cracks and construction joints wider than 1.5 mm and less than 6 mm.   

APPLICATION

Hydrotech® Monolithic Membrane 6125® must be applied continuously to the concrete substrate at an average thickness of 3 mm. Apply a 300 mm wide, 3 mm thick layer of Hydrotech® Monolithic Membrane 6125®, centered on the crack axis, and place a 150 mm wide elastomeric reinforcing sheet on top; the ends of the strips must be overlapped by at least 50 mm and bonded over a length of 150 mm. Avoid air pockets. Apply a second layer of hot Hydrotech® Monolithic Membrane 6125® and form a flashing with a reinforcing fabric or an elastomeric reinforcing sheet, as appropriate, in accordance with the minimum requirements of CAN/CGSB - 37.51 and the manufacturer's instructions. The more stringent requirements prevail.The thickness of both layers must have an average thickness of 5 mm, with no readings less than 4 mm.
