MIRADRI® 860/861

PRODUCT DESCRIPTION

Miradri 860 and Miradri 861 are self adhering sheet membranes consisting of 1.4 mm (56 mils) of rubberized asphalt laminated to 0.1 mm (4 mils) of polyethylene to form a minimum 1.5 mm (60 mils) membrane. The combination of two excellent waterproofing materials provides a high-performance, extremely durable waterproofing barrier.

Miradri 860/861 membranes are 91 .4 cm (3’) wide by 20.1 m 167’) long. The rubberized asphalt is delivered on a silicone release paper that serves as a carrier. The release proper is removed prior to application of the membrane. Miradri sheet membranes are completely cold-applied and require no special adhesives or heating equipment.

Miradri 860/861 should be covered with either Miradri 200V/300HV Protection Course or Miradrain Drainage Composites based on site-specific conditions.

APPLICATIONS:

Miradri 860/861 membranes are used for vertical and horizontal waterproofing on structural foundation walls and decks. Below grade foundation walls, tunnels, plaza decks and parking decks are all areas where Miradri 860/861 may be applied. Miradri 860/861 also may be used in interior areas like mechanical rooms, laboratories, and bathrooms.

Miradri 860 should be applied at temperatures of 4.4°C (40°F) and above. Miradri 861 should be used for applications between -3.9°C ( 25°F) up to a temperature of 29.4°C (85°F).

ADVANTAGES

Fully adhere membrane. Eliminates water migration which can otherwise cause leakage through cracks.
Factory controlled thickness. Eliminates thin spots which could otherwise be easily penetrated, allowing leakage.
Flexibility over cracks. Elastomeric properties accommodate normal expansion and contraction of the substrate.
Resists hydrostatic pressure. Delivers high-performance protection due to high strength backing film.
Easy to apply. Can be applied quickly and easily in the field.
Two-ply membrane High-performance polyethylene and rubberized asphalt.
No pinholing. Preformed sheet.
Cost competitive.
Total waterproofing system.
