GacoPoly

Benefits

• • QUICK AND EASY TO APPLY. Use GacoPoly LM60 to waterproof concrete, metal, and plywood in a single application with a squeegee, trowel, or brush. It requires minimal prep work and doesn’t need reinforcement, making the installation process straightforward.

• CREATES A MONOLITHIC WATERPROOF MEMBRANE. Your structure will receive a seamless, impermeable elastomeric membrane, protecting it from water damage.
• LOW ODOR. Ideal for indoor or high pedestrian traffic environments, minimizing disruptions during application.
• SOLVENT-FREE AND 100% POLYURETHANE TECHNOLOGY. 100% polyurethanes don’t lose wet film thickness (“WFT”) and dry film thickness (“DFT”).
• COLD APPLIED. There is far less room for error when using cold-applied, liquid waterproofing membranes than hot-applied rubberized asphalts. Less skill is required, and there is a significantly lower chance of moisture evaporation that can cause blistering or pinholes during the installation.
• PROVEN TRACK RECORD. For over 60 years, LM60 products have proven their reliability in challenging applications.
• BACKED BY GACO. Gaco offers a material and labor warranty for up to 20 years on GacoFlex LM60 liquid membrane systems when applied according to specifications.

Applications

• BETWEEN-SLAB OR BELOW-GRADE STRUCTURES. It’s challenging to reliably waterproof below-grade structures. Buildings can move, undergo fatigue cycles, and expand and contract. Maintaining waterproofing integrity is difficult, especially in cold temperatures. However, GacoPoly LM60 does not shrink or crack and has proven its reliability time and time again, even in challenging applications. LM60 can sustain 300% elongation (ASTM D412) and it’s rated at -50 °F (-45 °C) for a low temperature brittleness (ASTM D746).
• IRMA ROOFING SYSTEMS. LM60 is ideal for waterproofing flat or low-sloped concrete or plywood roof decks as a part of an Inverted Roof Membrane Assembly (“IRMA”), also known as an “upside down” roof. First, LM60 is applied to the concrete and allowed to cure. Then, polystyrene boards are placed over the membrane to protect it and provide thermal insulation, followed by a layer of filter fabric and ballast rock or concrete pavers to hold it all in place.
• VEGETATIVE ROOFS/GARDEN ROOFS. Vegetative roofs help keep your building cool and are environmentally friendly. They help control stormwater run-off and make attractive outdoor amenity spaces. But, not every waterproofing coating is safe for biodiversity.
• TANKS, PLANTERS, AND PODIUM DECKS. Use LM60 for horizontal and vertical waterproofing of unique structures such as tanks, planters, and podium decks, and better managing the flow of water around them.
