Negative-side waterproofing is an innovative and effective method used when it is not possible to apply waterproofing from the exterior side of a structure. Therefore, the materials are applied from the inside of the building. Specialized waterproof materials — such as crystallizing solutions, cementitious compounds, and injection polymers — penetrate deeply into the concrete structure and create a solid waterproof layer.
Where is negative-side waterproofing used?
- Basements and underground structures – ensures a dry and healthy environment.
- Tunnels and underground utilities – protects infrastructure from groundwater.
- Water reservoirs and pools – prevents internal water leakage.
- Old and historic buildings – a unique solution when exterior waterproofing is not an option.
