Car parks are exposed to a demanding mix of conditions: movement from wind loads, dynamic stresses from traffic, chemical exposure from de-icing salts, and surface wear from constant use. Without the right waterproofing and protection, early deterioration can occur. ALSAN, from SOPREMA, is a liquid-applied waterproofing system developed to handle these challenges. Fully reinforced and BBA-certified, ALSAN systems provide a seamless, durable barrier designed for exposed car park decks, ramps, and turning areas.
Each system is tailored to the project, typically including:
- A primer compatible with the substrate
- A waterproofing layer, such as ALSAN 770
- A protection coat like ALSAN 870 RS
- A coloured, slip-resistant finish, such as ALSAN 970 F
Additional options include drainage solutions, stair and column coatings, anti-graffiti and anti-carbonation finishes.
Proven Benefits
- BBA-certified for use on exposed parking decks
- UV-stable from primer to finish – no additional coating required
- Resistant to shear, wear and thermal movement
- Fast-curing PMMA resins – trafficable in approximately 1–1.5 hours (dependent on conditions)
- Choice of colour and slip resistance for zone marking and safety
Expansion Joint Solutions
Movement joints are a critical detail in multi-storey car parks. SOPREMA partners with MIGUA, a leading expansion joint system manufacturer, to provide coordinated solutions for joint movement, load resistance and waterproof continuity. MIGUA systems are engineered for car park use and integrate seamlessly with ALSAN waterproofing to maintain a continuous barrier across movement joints.
SOPREMA can offer guidance on MIGUA joint selection, detailing, and installation alongside ALSAN specifications, ensuring performance is maintained at these key points of movement.
Refurbishment Projects
For refurbishments, SOPREMA offers technical support starting with a site survey. We assess surface condition, identify any cracking, and provide a clear system proposal tailored to each zone.
ALSAN systems offer crack-bridging capability and fleece reinforcement where needed.
New Build Support
Early engagement on new build projects helps reduce future preparation requirements. ALSAN systems are suitable for various substrates and can be fully reinforced in areas where movement or cracking may occur over time.
Repair and Maintenance
ALSAN is designed to be easy to maintain and repair. Localised damage or modifications – such as around manholes – can often be repaired without removing the full surface.
After years of use, worn anti-slip coatings can often be cleaned and renewed without stripping the system. Maintenance guidance is available.
