Seamless, lightweight and flexible flat roofing systems

Amid the pressures and complexities of construction, life never stops. Nor should your roofing project. That’s why a little fluid thinking goes a long way. Our range of liquid applied waterproofing systems can be split into two categories, cold applied systems refer to liquid membranes that do not require the application of heat during their installation and our hot melt systems require heat via a bitumen boiler.

BMI Sealoflex is a comprehensive range of cold applied liquid waterproofing systems delivering complete flexibility, complete coverage and complete peace of mind – meeting every demand while minimising downtime and disruption to your project and the flow of life around it. Suitable for a vast array of applications and projects across the built environment, Sealoflex helps you work smarter without compromising quality. This is supported with dedicated training, industry-leading guarantees and full project technical and local support.

Combining unparalleled flexibility with fast installation and proven performance, BMI Sealoflex gives you practical, efficient, best value waterproofing solutions. From large, exterior roof areas to small, interior plant rooms, from complex details to occupancy-sensitive applications, BMI Sealoflex Systems benefit from ‘wet-on-wet’ application, combining greater internal bond strength with faster application, as primary waterproofing elements are applied in a single operation.
