Advanced Waterproofing Solutions for Building Envelope Protection in British Columbia
Northstrata Construction is an approved applicator of the SOPREMA ALSAN RS Detail liquid applied waterproofing system in British Columbia, delivering high-performance waterproofing solutions for strata buildings, commercial properties, balconies, podium decks, and complex building envelope assemblies.
As building envelope failures continue to impact multi-family and commercial buildings across BC, liquid applied PMMA membrane systems have become one of the most trusted waterproofing technologies for difficult transitions, penetrations, flashing details, balconies, and exposed traffic surfaces.
What Is ALSAN RS Detail Liquid Applied Membrane?
ALSAN RS is a rapid-curing PMMA (polymethyl methacrylate) liquid waterproofing membrane designed to create a fully bonded, seamless waterproofing barrier across challenging building envelope conditions. SOPREMA’s ALSAN RS system is engineered for long-term durability, superior adhesion, and seamless integration with modern roofing and waterproofing assemblies.
The system is commonly specified by:
- Building Envelope Engineers
- Roofing Consultants
- Property Managers
- Strata Councils
- Architects
- Restoration Consultants
- General Contractors
Why Building Envelope Engineers Specify ALSAN RS Systems
Seamless Waterproofing Protection
Unlike traditional sheet membranes, ALSAN RS creates a monolithic waterproofing membrane with no seams, overlaps, or welded joints. This dramatically reduces the risk of leakage at:
- Penetrations
- Mechanical curbs
- Balcony drains
- Parapet transitions
- Expansion joints
- Window-to-wall interfaces
- Irregular geometries
Exceptional Adhesion to Multiple Substrates
ALSAN RS systems are designed for adhesion to common construction materials including:
- Concrete
- Plywood
- Metal
- Existing SBS membranes
- Wood substrates
- Masonry
- Steel
- Base sheet membranes
SOPREMA specifically highlights the system’s compatibility with “multiple substrates on the same surface,” making it ideal for complicated restoration projects and strata remediation work.
Rapid Cure Times for BC Weather Conditions
One of the most important advantages for British Columbia projects is the rapid-setting PMMA chemistry.
ALSAN RS systems cure quickly, allowing contractors to:
- Minimize weather exposure
- Reduce project downtime
- Accelerate phased strata remediation projects
- Return balconies and walkways to service faster
- Complete detailing work during narrow weather windows
SOPREMA identifies ALSAN RS as ideal for “projects with time constraints.”
Common Applications in BC Strata & Commercial Buildings
Balcony Waterproofing
Balcony membrane failure is one of the most common causes of water ingress in strata buildings throughout Metro Vancouver and the Lower Mainland.
ALSAN RS liquid membrane systems are ideal for:
- Concrete balconies
- Wood-framed balconies
- Occupied strata buildings
- Balcony-to-wall transitions
- Door threshold detailing
- Cantilevered slab waterproofing
Podium Deck Waterproofing
Podium decks require durable waterproofing assemblies capable of handling:
- Thermal movement
- UV exposure
- Foot traffic
- Landscaping interfaces
- Drainage complexity
ALSAN RS reinforced systems provide high-performance waterproofing continuity across podium assemblies.
Roof Flashings & Penetration Detailing
Complex flashing conditions are among the highest-risk leak locations on commercial roofs.
ALSAN RS DETAILER and reinforced flashing systems are engineered for:
- Pipe penetrations
- Roof drains
- HVAC curbs
- Skylights
- Mechanical supports
- Vertical transitions
- Difficult retrofit conditions
SOPREMA describes ALSAN RS Detailer as a rapid-setting PMMA flashing resin designed for “small and challenging penetrations.”
Building Envelope Remediation Projects
ALSAN RS systems are frequently specified during:
- Leaky condo remediation
- Envelope renewal projects
- Strata depreciation report upgrades
- Parkade waterproofing repairs
- Roof replacement transitions
- Terrace restoration
Benefits for Strata Managers & Property Managers
Reduced Risk of Water Damage
Water ingress can result in:
- Rot and structural deterioration
- Mold remediation costs
- Insurance claims
- Resident disruption
- Litigation exposure
A seamless PMMA membrane system helps minimize common failure points associated with traditional membrane overlaps and mechanical fasteners.
Minimal Occupant Disruption
Because ALSAN RS systems cure rapidly, restoration projects can often proceed faster than conventional waterproofing systems.
Benefits include:
- Reduced disruption to residents
- Faster balcony re-opening
- Improved project scheduling
- Reduced weather delays
Long-Term Waterproofing Performance
SOPREMA highlights ALSAN RS systems for:
- Chemical resistance
- Grease resistance
- UV stability
- High durability
- Long-term waterproofing integrity
Why PMMA Liquid Applied Waterproofing Is Growing in BC
Building science professionals increasingly specify PMMA liquid applied membranes because they provide:
- Seamless detailing
- Superior flexibility around penetrations
- Reinforced waterproofing assemblies
- Compatibility with complex restoration work
- Fast cure times in unpredictable climates
Industry professionals on roofing forums consistently identify ALSAN RS as a premium PMMA waterproofing system for demanding applications.
