Stopping water ingress with hydrophilic expanding resins
Active water ingress: immediate sealing with hydrophilic expanding resins
Active water ingress is one of the most critical issues in the construction and infrastructure sector, especially when water penetrates structures continuously, suddenly or under pressure. In such conditions, traditional waterproofing systems are often ineffective or excessively invasive.
Whether affecting basements, construction joints, structural cracks, manholes, lift shafts or foundation weak points, water ingress can cause severe damage and compromise both functionality and safety. Hydrophilic expanding resins represent the most effective technical solution for rapidly stopping leaks, acting from within the structure and eliminating the need for invasive demolition.
Typical challenges in water ingress control
Stopping active water ingress requires expertise, precision and careful management of on-site conditions:
Pressurised water flow: Water may penetrate through cracks, joints or construction defects under significant hydraulic pressure, rendering surface treatments ineffective.
Irregular and unpredictable water paths: Water often travels through internal concrete capillaries that are invisible from the outside.
Operational continuity requirements: Many environments (car parks, technical rooms, industrial plants) must remain accessible and cannot be shut down for extended works.
Deep structural intervention: Effectively stopping the leak requires reaching the source through precise micro-drilling and targeted injections.
Compatibility with existing structures: Interventions must be localised and must not compromise the structural integrity of the building or infrastructure.
The FES Global Group approach
FES S.p.A. specialises in the treatment of active water ingress using high-performance hydrophilic expanding resins and highly accurate application techniques.
Inspection and identification of critical points: Mapping of water paths, identification of infiltration routes and analysis of root causes.
Strategically positioned injection holes: Targeted drilling allows precise access to water pathways within the structure.
Injection of hydrophilic expanding resins: Upon contact with water, the resin rapidly expands, sealing cracks, voids and micro-channels.
Immediate leak stoppage: The expansive reaction stops water ingress within seconds or minutes, even under high hydraulic pressure.
Final sealing and structural consolidation: Completion of the intervention with waterproofing materials and, where necessary, structural reinforcement of treated areas.
Fast and non-invasive operations: Works carried out without major demolition and with minimal disruption to ongoing activities.
