Waterproofing membranes provide a critical capacity to protecting various structural components, principally roofs, foundations and engineering structures, fr om the damaging effects of water penetration and moisture accumulation. As important as waterproofing membranes are, traditional membranes require torching to create adhesion, a process that itself can be costly, complicated and potentially lim it the performance of the waterproofing product. TECHNONICOL's various self-adhesive waterproofing membranes greatly simplify the application process without compromising waterproofing capabilities.
TECHNONICOL offers several self-adhesive membranes for specific applications:
- ULTRAFLEX SA is a polyester reinforced underlayment used for roofs as well as a vapor barrier. Its protective top covering comes in either sand or polymer film, depending on the application area.
- ULTRAFLEX SA 7000-X is used as a waterproofing membrane for foundations and engineering structures that also offers radon protection as well as self-healing in the event of mechanical penetration.
- ULTRAFLEX SA NB is used specifically for foundation and indoor waterproofing. The high flexibility of the material features easy installation even in a closed area.
- ULTRAFLEX SA NBS, designed for indoor waterproofing, incorporates a spunbond top layer that allows the direct application of tiles, eliminating the need for a protective sand-cement screed layer.
- VAPORSTOP CA 500 is a high-performance vapor barrier for roofing applications that allows installers to walk on top of the membrane during installation due to its high tensile strength. Likewise, given its high adhesion properties, it will not be disturbed by wind during the installation.
- UNDERLAY NEXT SELF is used in the leak-prone valleys and eaves of pitched roofs with a wood decking. The underlay membrane incorporates polypropylene for enhanced strength as well as allowing installers to walk on the surface during installation.
All these membranes are made of premium SBS-modified bitumen compound that provide exceptional flexibility and durability as well as waterproofing properties.
Advantages of self-adhesive bitumen system
There is a variety of advantages to using self-adhesive membranes:
- Since no heat source is used, self-adhesive membranes can be used on top of flammable materials such as wood, XPS and OSB.
- Because no gas or flame is used, there is less expense relative to materials needed for installation.
- No special skill is required to apply the self-adhesive membrane, decreasing training expenses while reducing the likelihood of injury or damage from misapplied flame.
- Faster application time due to easy self-adhesive application, which allows for faster completion of projects.
- No noxious fumes or odors from gas and flame.
- Different membranes can incorporate different properties for varying applications, providing versatility while retaining waterproofing properties.
- Self-healing properties of SBS-membranes increase structural stability and waterproofing performance in case of mechanical penetrations (e.g. from nails for roofing installations).
Main uses
The main uses of self-adhesive membranes are to provide waterproofing underlayment for roofs (especially for roofs that utilize wood decking), waterproofing for indoor areas that entail high moisture exposure (such as bathrooms), waterproofing of foundations and other engineering structures, and corrosion protection for exposed piping and other metallic components.
Given the versatility and benefits of self-adhesive membranes, it is easy to see how significantly they can improve performance and simplify installation. Please let us know how we can guide you to find the right self-adhesive membrane for your next project.
