What is SBS Impermeabilizante Para Techos?
SBS, or Styrene-Butadiene-Styrene, is a type of rubber-modified bitumen used extensively in the production of waterproofing membranes. SBS membranes combine the excellent adhesion and elasticity of rubber with the durability and waterproofing properties of bitumen.
SBS impermeabilizante para techos refers specifically to SBS-modified bituminous membranes designed for roof waterproofing. These membranes are flexible, resistant to temperature changes, and able to withstand mechanical stresses such as expansion and contraction of roof materials under different weather conditions.
Why Use SBS Modified Bitumen?
- Enhanced Flexibility: SBS modification allows the membrane to stretch and recover without cracking or losing integrity.
- Superior Durability: SBS membranes resist aging caused by UV exposure and oxidation better than traditional bitumen.
- Excellent Adhesion: This improves bonding with substrates and prevents water ingress along joints.

Benefits of Blue Roof Torch Applied Waterproofing Membrane
By choosing Blue Roof SBS membranes, construction projects gain substantial long-term advantages.
Waterproofing Excellence
The fundamental benefit is a watertight roof system that prevents leaks, mold growth, and structural weakening. The heat-welded seams ensure a continuous membrane without joints susceptible to water ingress.
Thermal Movement Accommodation
The elasticity of SBS-modified bitumen allows the membrane to absorb stresses caused by thermal expansion and contraction. This minimizes cracking or disbonding compared to rigid waterproofing alternatives.
UV and Weather Resistance
The membrane’s blue top coating helps reflect sunlight and resists damaging UV rays that degrade many conventional membranes. This extends the membrane’s usable life outdoors.
Ease of Installation
Despite requiring skilled application with propane torches, the membrane’s torch applied nature allows quick bonding to substrates without adhesives or primers, speeding up construction timelines.
Cost Efficiency Over Time
While initial material and installation cost may be moderate, the durability and minimal maintenance reduce lifecycle expenses, making Blue Roof SBS membranes very cost-effective.
Step-by-Step Installation Process
Proper installation is crucial to maximizing the benefits of the membrane. Following best practices ensures a reliable waterproofing system.
1. Surface Preparation
The roof deck should be clean, dry, and free from dust, grease, or loose materials. Surface irregularities must be repaired to obtain a smooth substrate. Priming with an approved primer is recommended for porous surfaces like concrete.
2. Measuring and Cutting
Membrane rolls are cut to length with consideration for overlaps between adjoining sheets, typically 8-10 cm. The membrane edges may have polyethylene release films which should be removed just before torching.
3. Positioning Membrane
Place membrane rolls on the surface loosely before heating. Align carefully to avoid wrinkles or gaps, which can cause failures.
4. Torch Application
Using a propane torch, evenly heat the underside of the membrane until the bitumen begins melting and becomes tacky. Press the membrane onto the substrate ensuring uniform adhesion. Use a roller to press out any trapped air bubbles or wrinkles.
5. Sealing Seams
Adjacent membranes must be overlapped adequately and torch welded to create a monolithic waterproof layer. Reinforce critical detail areas such as edges, corners, drains, and penetrations with additional membrane strips or specialized flashing.
6. Final Inspection
After installation, inspect the entire surface for any unbonded areas, pinholes, or defects. Promptly repair any issues to ensure continuous waterproofing protection.
Maintenance and Longevity
With proper installation, Blue Roof SBS membranes provide long-lasting protection often exceeding 20 years.
Routine Inspections
Scheduled roof inspections, ideally biannually, help detect damage caused by physical impact or weather.
Cleaning
Remove debris and dirt to prevent damage to the membrane surface and drainage blockages.
Minor Repairs
Patch tears or punctures promptly with compatible SBS patches and torch application techniques.
Re-Coating
In some cases, UV protective coatings may be applied to prolong membrane lifespan.
Environmental and Safety Considerations
Blue Roof SBS membranes are produced using bitumen sourced as a petroleum derivative. While not entirely ecological, their long service life reduces resource consumption compared to frequent replacements.
During installation involving torch heating, safety precautions are critical to prevent fire hazards. Proper ventilation, protective equipment, and trained personnel are mandatory to ensure safety on site.
