Torch-On Bituminous Membrane Waterproofing

At Grupo Eleven Solutions®, we deliver advanced waterproofing systems engineered to safeguard structures exposed to heavy moisture, extreme weather, and intensive use. Torch-on bituminous membrane rolls provide a proven, resilient barrier for roofs, underground walls, and deep foundations. With over 35 years of industry experience, we deploy systems approved by leading manufacturers that ensure high performance and extended service life, protecting your commercial, industrial, or hospitality real estate assets against water damage and deterioration.

Handled exclusively by specialized, skilled labor, our torch-down installations establish a fully adhered, seamless waterproofing shield across flat concrete decks and subterranean footings. We utilize products holding national and international certifications that guarantee reliable physical and chemical stability under aggressive climatic conditions. Furthermore, our dedicated team provides a free on-site inspection and diagnosis, backing every completed project with a comprehensive written warranty for long-term peace of mind.

What is Bituminous Roll Waterproofing and How Does It Work?

Bituminous rolls are prefabricated waterproofing membranes manufactured with polymer-modified bitumen reinforced with non-woven polyester or fiberglass mats. This combination delivers exceptional tensile strength, puncture resistance, and elongation capability to accommodate building movement and thermal expansion. The membrane functions as an impenetrable barrier that prevents standing water, heavy tropical rainfall, and subterranean hydrostatic pressure from infiltrating structural concrete slabs, foundation footings, and retaining walls.

Installation is accomplished through torch application, where controlled heat melts the bottom asphalt compound, fusing the roll securely to the primed substrate and overlapping adjacent sheets. This thermal fusion eliminates vulnerable seams, forming a uniform, continuous monolithic blanket over horizontal or vertical planes. These membranes are ideal for exposed roofs featuring mineral granule surfaces as well as below-grade foundations that demand heavy-duty water exclusion.
