Specialized Waterproofing Solutions Projects

Documented case studies from our specialized waterproofing solutions work across Lebanon — real problems, engineered solutions, measurable results.

Precision Sealing & Finishing: Stone-to-Aluminum InterfaceWaterproofing
Lebanon

Stone-to-Aluminum Interface

In this project, our team focused on the technical integration of modern aluminum door systems with natural stone masonry. Achieving a seamless, weather-tight transition between these two distinct materials requires both precision and the right industrial-grade components.

Stone Facade Restoration & WaterproofingWaterproofing
Lebanon

Heritage & Modern Waterproofing

This project showcases our specialized approach to protecting and enhancing traditional stone structures. We were tasked with resolving water infiltration issues while maintaining the original aesthetic and color of the masonry — both on a modern yellow-stone villa and a classic Lebanese traditional house.

Advanced Negative-Side Waterproofing: Elevator Shaft RemediationWaterproofing
Lebanon

Advanced Negative-Side Waterproofing

Managing water ingress in below-grade structures like elevator shafts requires specialized engineering, especially when the exterior is inaccessible. This project involved a critical "negative-side" waterproofing intervention for a closed elevator shaft that suffered from persistent leaks.

Multi-Villa Mountain Waterproofing CampaignWaterproofing
Chouf, Lebanon

Driveways, Terraces & Foundations

We executed a coordinated waterproofing campaign across five mountain properties in the Chouf district, covering driveways, exterior terraces, and the bases of new buildings. The objective was to lock the new envelopes against the heavy Mediterranean winter rainfall before tile and stone finishes were laid.

Heritage Building Plaster Ceiling RestorationHeritage Restoration
Lebanon

Crack Injection & Breathable Plaster Repair

We restored the water-damaged interior plaster ceilings of a traditional Lebanese stone house. Decades of slow water ingress had blistered the lime plaster, exposed the wood lath, and stained the original wall finishes. The owner wanted the historic character preserved, not replaced.
