Facades Rehabilitation
Project overview
Client: Amer Ghandour
Project: Waterproofing of Siran Building
Status: Completed on August 2019
Location: Beirut, Lebanon
As a member company of ARKON NETWORK, RECAP sarl successfully executed the waterproofing and façade protection works for Siran Tower, a prestigious multi-storey residential development in Beirut, Lebanon.
The project focused on protecting the building envelope against water ingress and environmental deterioration by implementing comprehensive waterproofing systems for exposed balconies, façades, and rooftop areas. The works were designed to improve the durability, watertightness, and long-term performance of the building while preserving its architectural appearance.
All waterproofing systems were installed in accordance with manufacturer recommendations and international best practices, ensuring reliable long-term protection against moisture penetration and weather exposure.
protection works.
Scope of Work
- Waterproofing of all exposed balconies using liquid-applied polyurethane membrane systems.
- Water testing and quality verification of completed waterproofed areas.
- Surface preparation and treatment of façade substrates.
- High-pressure water jet cleaning of natural stone façades.
- Replacement of deteriorated façade joints using weather-resistant sealants and repair mortars.
- Application of breathable water-repellent protective coatings to natural stone cladding.
- Complete rooftop waterproofing using liquid polyurethane membrane systems following proper surface preparation.
- Final inspection, testing, and quality assurance.
Waterproofing works
Specialized suspended access platforms were utilized to safely execute façade waterproofing and maintenance works at elevated locations. This access methodology allowed efficient treatment of all external building elevations while maintaining high standards of workmanship, safety, and quality control
throughout the project.
one complete façade elevation was surface prepared and finished with a render-textured elastomeric acrylic coating, providing a seamless, flexible, and weather-resistant protective finish. The elastomeric system enhances resistance to water penetration, UV exposure, thermal movement, and hairline cracking while improving the building’s overall appearance and long-term durability.
