WHEN WATERPROOFING IS NO LONGER ENOUGH
Water ingress is often first noticed as a surface problem.
Blistering paint. Damp staining. Delaminating plaster. Efflorescence. Cracking. A leaking concrete roof. Water penetrating a basement or parking structure.
But what happens when the problem is no longer simply the waterproofing?
A recent site observation at a multi-occupancy building raised exactly this question. Significant moisture ingress around adjacent wet-service and plumbing areas had progressed to visible failure of coatings and deterioration of the underlying plastered surfaces.
At this stage, simply applying another coating may address the symptom without rehabilitating the substrate beneath it.
This is the subject of our latest Publication:
“When Waterproofing Is No Longer Enough — Engineering the Rehabilitation of Moisture-Damaged Cementitious Structures.”
It examines the problem from an asset-preservation perspective:
Water source → Moisture ingress → Substrate deterioration → Diagnosis → Removal of unsound material → Cementitious reinstatement → Protection → Verification
It also explores the engineering philosophy behind our FibreMatrix Cementitious Composite Platform.
FibreMatrix is an engineered polymer-modified, fibre-reinforced cementitious powder composite used together with either Poly-Vinex 7401 or Poly-Vinex IND40 — both themselves fibre-reinforced polymer technologies.
Through PCG's Variable Polymer Ratio (VPR) methodology, the composite can be configured for different rehabilitation functions without adding water,from paintable cementitious waterproofing and rehabilitation slurries, through skimmable resurfacing, to higher-build repair mortar consistencies.
The appropriate configuration depends on the substrate, deterioration mechanism, exposure and required service performance.
That distinction is important.
A moisture-damaged residential wall, a ±3,000 m² exposed concrete roof, a basement parking structure and industrial concrete infrastructure may all exhibit water-related deterioration — but they should not automatically receive the same remediation specification.
Our engineering principle is simple:
Don't waterproof over deterioration. Diagnose the mechanism, rehabilitate the substrate, then engineer the protection.
We invite Civil-, Structural- & Consulting Engineers, Quantity Surveyors, Architects, Concrete Rehabilitation Specialists, Waterproofing Contractors, Building Contractors, Facilities Engineers and Asset Owners to engage with us on project-specific concrete and cementitious rehabilitation requirements.
We are equally interested in collaboration with engineering and contracting firms seeking alternative material technologies for challenging remediation projects.
