Repair & Rehabilitation Waterproofing

Restoring strength. Renewing protection.

Aging structures often suffer from water ingress, structural cracks, dampness, and corrosion due to prolonged exposure to environmental elements. At Ethios Group, our Repair & Rehabilitation Waterproofing solutions are designed to breathe new life into such structures—addressing both visible damage and underlying weaknesses.

Our approach focuses on

‍

Leak Arresting & Crack Treatment – Using injection grouting techniques with PU or epoxy resins to seal active leaks and deep cracks from within the concrete mass.
‍
Surface Reproofing – Application of high-performance cementitious or elastomeric coatings on terraces, walls, and roofs to restore waterproofing layers that have worn out over time.
‍
Sealant Replacement & Detailing – Replacing damaged sealants in joints, expansion gaps, and parapet walls with flexible PU or polysulphide sealants to prevent moisture entry.
‍
Membrane Overlays – Retrofitting existing surfaces with APP/SBS membranes or liquid membranes for an added layer of long-term water resistance.
‍
Reinforcement Protection – Applying anti-corrosion coatings to exposed rebars and damaged concrete zones to halt deterioration and extend service life.

Typical Applications

Old Basements – Restores waterproofing integrity against rising damp and seepage.

Leaking Terraces & Roofs – Repairs damaged surfaces to prevent recurring leaks.

Cracked Water Tanks – Seals active leaks and reinforces water containment.

Damaged Wet Areas – Re waterproofs toilets, bathrooms, and utility zones.

Retrofitting of Old Buildings – Enhances waterproofing for aged structures.

Structural Joints & Expansion Gaps – Treats vulnerable joints to prevent water ingress.

Key Benefits

Stops active leakage and prevents future moisture ingress.

Improves safety and durability of aged concrete elements.

Increases resistance to chemicals, weather, and UV exposure.

Compatible with both heritage and modern construction.

Reduces life-cycle maintenance costs with long-lasting treatment systems.

We use a combination of liquid-applied membranes, crystalline admixtures, cementitious coatings, and HDPE sheets, selected based on site conditions, structural damage, and exposure levels. Our focus is on delivering a seamless, multi-layered waterproofing system that reintegrates with the existing structure and performs reliably for years.
