Materials Used
Two-component, polymer-modified bituminous coating (PMBC) – DEUXAN 2C, known for its superior durability, flexibility, and crack-bridging capability. Applied as a seamless protective layer for structures in direct contact with groundwater.
Project Overview
This project encountered a critical waterproofing challenge: the basement had been constructed without a dedicated Tanking System, exposing the completed foundations and raft to potential water ingress. The absence of such protection created a high risk of seepage and long-term structural damage.
Solution Implemented
The DEUXAN 2C system was selected once again for its proven performance in underground and post-construction waterproofing applications. Using a trowel-applied method, a continuous 4 mm-thick layer was built over the entire surface, reinforced to handle structural movements and eliminate joints that could compromise waterproofing integrity. The system’s direct bond to the substrate prevented water migration beneath the protective layer—a common failure point in sheet-based systems, particularly where no Tanking System exists.
Technical Advantages
- Withstands high water pressure and accommodates soil settlement.
- Crack-bridging capacity of up to 6 mm with reinforcement.
- Long-term resistance to water penetration and moisture.
- Effective barrier against radon gas, promoting a safe indoor environment.
Outcome:
The basement was fully secured against water ingress, ensuring the complex’s foundations remain protected and operational reliability is maintained for decades to come.
