Walkway Waterproofing System
Home > Systems > Flat Roofs > Exposed > Walkway Waterproofing System

Modern architecture often features exposed concrete roofs, prized for their clean lines and aesthetic appeal. However, concrete is inherently porous and vulnerable to water ingress, which can lead to deterioration, corrosion of internal reinforcement and long-term structural damage.
Alchimica’s high-performance waterproofing and protection systems are engineered to provide durable, seamless protection for concrete walkways and exposed roofs — whether flat or sloped.
Key features include:
- Exceptional weather and UV resistance.
- High mechanical and thermal durability.
- Protection against water, chemicals and wear.
- Long-term prevention of corrosion and surface degradation.
Ideal for both new builds and refurbishment projects, the system enhances the lifespan of concrete structures while maintaining their visual and functional integrity — even under high foot traffic or demanding environmental conditions.
