Description
COLPHENE LM BARR is a single-component, liquid-applied, moisture curing elastomeric STPE waterproofing membrane.
UNITS PER SKID: 36
VOLUME: 19L
Material Use:
COLPHENE LM BARR is a high-performance, single-component, liquid-applied waterproofing membrane designed for both below-grade and above-grade applications. It is primarily used for waterproofing foundations, plaza decks, planter boxes, and other structural elements requiring a durable, elastomeric barrier. The product is based on STPE (Silyl Terminated Polyether) technology and cures by moisture to form a seamless, flexible, and highly adhesive membrane.
System Components:
The COLPHENE LM BARR waterproofing system includes the following components:
- COLPHENE LM BARR: The primary waterproofing membrane.
- POLYFLEECE: A reinforcement fleece used in conjunction with COLPHENE LM BARR for enhanced durability and crack-bridging performance.
- COLPHENE BARR FLASHING: Used for detailing, patching, and leveling surface defects, joints, fasteners, and penetrations prior to membrane application.
- ALSAN RS CLEANER or xylene-based solvent: Used for surface cleaning prior to reapplication or overlapping after extended exposure.
Applications:
COLPHENE LM BARR is suitable for:
- Below-grade waterproofing of concrete foundations and retaining walls.
- Waterproofing of plaza decks and horizontal surfaces.
- Sealing of wells and other underground structures.
- Waterproofing planter boxes and other above-grade elements where a durable, elastomeric membrane is required.
Application Details:
- Surface Preparation: Substrates must be clean, dry to the touch, and free of contaminants. Green concrete is acceptable with a recommended cure time of 3–7 days.
- Application Methods: Apply using a roller, brush, or flat squeegee. For reinforced systems, embed POLYFLEECE into the wet membrane and ensure full saturation.
- Detailing: All details must be reinforced with two layers of COLPHENE LM BARR (minimum 1.5 mm or 60 mils each) and POLYFLEECE.
- Membrane Thickness:
- Vertical surfaces (unreinforced): 2 layers of 0.8 mm (30 mils) = 1.5 mm (60 mils) total.
- Vertical surfaces (reinforced): 2 layers of 1.5 mm (60 mils) = 3.0 mm (120 mils) total.
- Horizontal surfaces (reinforced): 2 layers of 1.5 mm (60 mils) = 3.0 mm (120 mils) total.
- Coverage Rates:
- 0.8 mm (30 mils): ~54 ft²/gal
- 1.1 mm (45 mils): ~36 ft²/gal
- 1.5 mm (60 mils): ~27 ft²/gal
- 3.0 mm (120 mils): ~13.5 ft²/gal
- Curing Times:
- Dry to touch: ~60 minutes at 21°C (70°F), 50% RH
- Ready for backfill or protection: 24 hours
- Recoat window: within 72 hours; if exceeded, clean with ALSAN RS CLEANER before recoating
- Environmental Conditions:
- Application temperature (ambient and material): 2°C to 35°C (35°F to 95°F)
- Substrate temperature: 2°C to 48.9°C (35°F to 120°F)
- Avoid application if rain is expected within 2 hours
- Ensure substrate and ambient temperatures are above dew point to prevent condensation
Special Notes:
- UV Resistance: COLPHENE LM BARR is not UV stable and must not be exposed to UV rays for more than 90 consecutive days. If longer exposure is expected, a UV barrier must be applied.
- Protection Course: A protection layer is required before installing overburden or backfill.
- Reinforcement: POLYFLEECE is mandatory for all horizontal surfaces and detail areas. For plaza decks, extend the membrane 20 cm (8") above the overburden on vertical surfaces.
- Storage: Store in original, unopened containers in a cool, dry place away from direct sunlight. Shelf life is 12 months at 21°C (70°F) and 50% RH.
- Cleaning: Clean tools and spills immediately with ALSAN RS CLEANER, xylene, or mineral spirits. Cured material is difficult to remove.
System Compatibility:
COLPHENE LM BARR is designed to work as a system with COLPHENE BARR FLASHING and POLYFLEECE reinforcement. It does not require a primer on most concrete surfaces but may benefit from surface cleaning or adhesion testing (e.g., 180° peel test) for optimal performance. The system is ideal for integration into SOPREMA’s broader waterproofing assemblies and can be used in conjunction with other SOPREMA protection and drainage layers as specified.
