Our Waterproofing & Leakage Treatment Services

1. Roof Waterproofing

Roofs are continuously exposed to rainfall, sunlight, temperature changes, and standing water. Poor drainage, cracks, deteriorated joints, and damaged waterproofing layers can lead to leakage in the floors below.

CHEMFIX offers suitable roof waterproofing systems based on the roof condition and the existing surface.

Our services include:

– Inspection of visible cracks, joints, and leakage-prone areas
– Removal of loose coatings and preparation of the substrate
– Repair of suitable cracks and surface defects
– Application of compatible primer and waterproofing coating or membrane
– Treatment of parapet walls, pipe penetrations, and selected junctions
– Inspection of drainage arrangements and completed application

Suitable applications: Residential rooftops, apartment buildings, commercial roofs, and selected industrial roof areas.

2. Bathroom & Toilet Waterproofing

Water leakage from bathrooms and toilets can damage ceilings, walls, plaster, paint, and adjacent rooms. Effective waterproofing requires proper treatment of the floor, wall-floor junctions, pipe penetrations, and other vulnerable areas.

Our services include:

– Assessment of leakage and suspected water entry points
– Waterproofing beneath suitable floor finishes
– Treatment of wall-floor junctions and pipe penetrations
– Application of compatible waterproofing membranes or coatings
– Protection of the waterproofing layer before tile installation
– Water testing where appropriate and safe for the installed system

Suitable applications: Residential bathrooms, apartment toilets, commercial washrooms, and changing rooms.

3. Basement & Underground Structure Waterproofing

Basements and underground structures may experience water ingress because of groundwater pressure, defective joints, cracks, or inadequate external waterproofing.

CHEMFIX evaluates the site conditions and recommends a suitable system according to water pressure, accessibility, substrate condition, and the source of leakage.

Our services include:

– Assessment of water seepage and visible damp areas
– Treatment of suitable construction joints and penetrations
– Crack injection using an appropriate resin system where required
– Application of compatible waterproofing coatings or membranes
– Selected negative-side waterproofing solutions where external access is unavailable
– Recommendations for drainage and water-pressure management where necessary

Suitable applications: Basement walls, underground parking, lift pits, retaining structures, and selected below-ground utility areas.

4. Water Tank & Reservoir Waterproofing

Water tanks require waterproofing materials compatible with the tank structure and the intended water use.

Our services include:

– Assessment of cracks, joints, and surface defects
– Preparation and repair of the concrete substrate
– Application of a suitable waterproofing system
– Treatment of pipe entries and construction joints
– Inspection and water-retention testing where appropriate

For potable-water tanks, only materials specifically approved or documented as suitable for contact with drinking water should be selected. The coating system must also be compatible with the tank’s operating conditions.

Suitable applications: Concrete water tanks, underground reservoirs, service tanks, and selected water-storage structures.

5. Exterior Wall Waterproofing

Exterior walls are exposed to driving rain, weathering, cracks, porous plaster, and deteriorated protective coatings. These conditions can cause damp patches, peeling paint, and moisture penetration into interior spaces.

Our services include:

– Inspection of external cracks, joints, and defective coatings
– Repair of suitable cracks and damaged plaster
– Treatment of exposed wall junctions and penetrations
– Application of compatible water-repellent treatments or protective coatings
– Exterior wall dampness treatment based on the identified cause

Suitable applications: Apartment buildings, commercial properties, boundary walls, and exposed building facades.

6. Balcony, Terrace & Wet-Area Waterproofing

Balconies, terraces, and other exposed wet areas are vulnerable to leakage through joints, cracks, and defective waterproofing layers.

Our services include:

– Inspection of floor surfaces and junctions
– Treatment of cracks and construction joints
– Application of a compatible waterproofing membrane or coating
– Protection of the waterproofing layer beneath the specified finish
– Review of slope and drainage provisions

7. Water Leakage & Dampness Treatment

Not every damp patch is caused by failed waterproofing. Leakage may originate from plumbing defects, roof seepage, groundwater, condensation, or moisture rising through masonry.

CHEMFIX identifies the likely source before recommending a treatment system.

Our services include:

– Roof and slab leakage assessment
– Bathroom leakage and inter-floor seepage investigation
– Damp wall treatment
– Localized crack and joint leakage repair
– Plumbing-related leakage identification and referral where required
– Efflorescence and salt-affected surface assessment

Effective treatment focuses on controlling the source of moisture rather than merely covering the visible damp patch with paint or coating.

Our Waterproofing Systems

CHEMFIX selects the waterproofing method according to the application, substrate, water exposure, and required finish.

Cementitious Waterproofing: Suitable cement-based waterproofing systems for selected concrete and masonry surfaces, bathrooms, and other compatible wet areas.

Acrylic Waterproofing Coatings: Flexible, water-based coatings for suitable exposed surfaces, including selected roofs and exterior walls. Product selection depends on weather exposure, ponding-water conditions, and manufacturer specifications.

Polyurethane Waterproofing: Suitable polyurethane membrane systems for applications requiring flexibility and crack-bridging performance, subject to substrate moisture, exposure, and product requirements.

Bituminous Waterproofing: Suitable bituminous coatings or membranes for selected foundations, retaining structures, and below-ground applications.

Crack Injection Systems: Appropriate polyurethane or epoxy injection systems for specific leakage or structural crack conditions. The resin must be selected according to whether the crack is active, wet, moving, or structural.

Joint Sealants & Waterstops: Suitable materials for selected construction joints, movement joints, penetrations, and other vulnerable interfaces.

The final system is recommended after assessing site conditions. Not every product or waterproofing method is suitable for every application.

Our Waterproofing Process

Step 1: Site Inspection & Diagnosis

We inspect the affected area, identify visible defects, review moisture conditions, and investigate likely sources of leakage.

Step 2: Technical Recommendation

Based on the findings, we recommend a suitable waterproofing or leakage-treatment system and define the required preparation and application procedure.

Step 3: Quotation & Scope Confirmation

We provide a project quotation covering the agreed work area, materials, labour, surface preparation, application steps, and relevant exclusions.

Step 4: Surface Preparation

Loose material, defective coatings, and unsuitable surface contaminants are removed as required. Cracks, joints, and substrate defects are treated according to the selected system.

Step 5: Waterproofing Application

The specified primer, membrane, coating, sealant, or injection material is applied according to the product technical data sheet and the approved method statement.

Step 6: Curing & Protection

The applied system is allowed to cure for the specified period and is protected from premature water exposure, damage, or incompatible finishing work.

Step 7: Quality Inspection & Handover

The completed work is inspected, and appropriate water testing or other checks are carried out where applicable. Relevant application and maintenance instructions are provided to the client.

Frequently Asked Questions

Q1. What causes roof leakage?

Roof leakage can result from cracks, defective joints, damaged waterproofing layers, poorly sealed pipe penetrations, inadequate drainage, or deterioration of the roof surface. An inspection helps identify the likely cause.

Q2. Can waterproofing be applied over existing tiles?

Some compatible systems may be applied over properly prepared tiled surfaces, but others require tile removal or a different preparation method. The existing tile condition, adhesion, drainage, and selected product specifications must be assessed first.

Q3. How long does waterproofing last?

Service life depends on the material, application quality, substrate condition, weather exposure, movement, drainage, and maintenance. The expected service period and warranty, if offered, should be stated for the specific system and project.

Q4. Can a damp wall be treated by applying a waterproof coating from inside?

In some cases, a suitable internal or negative-side treatment may help. However, the correct method depends on whether the moisture comes from rain penetration, plumbing leakage, groundwater pressure, or rising damp. The underlying cause should be addressed wherever possible.

Q5. Do you supply waterproofing chemicals only?

Yes. CHEMFIX can provide construction chemicals and related materials for suitable applications. Application services and complete project contracts can also be discussed separately.

Q6. Do you provide complete waterproofing contracts?

Yes. Project-based proposals can include site inspection, material supply, surface preparation, application labour, supervision, and agreed quality checks.

Q7. Do you provide a warranty?

Warranty terms depend on the selected waterproofing system, the scope of work, substrate conditions, and agreed maintenance requirements. Any applicable warranty should be documented in the project agreement.
