A leaking bathroom or toilet is more than just a nuisance — it is a serious problem that can cause long-term damage to your floors, ceilings, walls, and structural elements. If you are looking for reliable bathroom and toilet waterproofing in Pasig or Mandaluyong, Mackintosh Corporation is the licensed waterproofing specialist that property owners and contractors trust to get it done right.
With expert knowledge in wet area waterproofing systems, world-class materials, and a team of professionally trained applicators, Mackintosh Corporation delivers durable, leak-free bathroom and toilet waterproofing solutions for residential homes, condominiums, commercial offices, hotels, hospitals, and all types of buildings across Pasig, Mandaluyong, and Metro Manila.
Why Bathroom and Toilet Waterproofing Is Essential
Bathrooms and toilets are the most water-exposed areas in any building. Daily use, constant moisture, and the presence of plumbing fixtures make these spaces highly vulnerable to water seepage — especially through grout lines, pipe penetrations, floor and wall junctions, and aging tile adhesive. Without proper waterproofing underneath the tiles and finishes, water silently infiltrates the substrate and causes progressive damage that is expensive to repair.
Common problems caused by poor or missing bathroom waterproofing include:
- Water stains and wet patches on ceilings of floors below
- Peeling paint and bubbling plaster on walls and ceilings
- Mold and mildew growth causing health hazards and foul odors
- Damaged floor and wall tiles due to substrate deterioration
- Corrosion of steel reinforcements in concrete slabs
- Structural weakening of floors and beams over time
- Costly demolition and repair work that disrupts occupants
Proper bathroom and toilet waterproofing applied by a professional contractor prevents all of these problems — protecting your property and saving you from far more expensive repairs down the road.

Mackintosh Corporation is a PCAB-licensed Waterproofing Specialty Contractor (License No. 34979) with extensive experience in bathroom, toilet, and wet area waterproofing for all building types across Pasig, Mandaluyong, and the entire Metro Manila area.
Pasig and Mandaluyong are among the most densely developed cities in Metro Manila, with a high concentration of residential condominiums, commercial buildings, BPO offices, hotels, and mixed-use developments. Mackintosh Corporation is experienced in working within the constraints of occupied buildings and active construction sites in these cities, delivering quality waterproofing work with minimal disruption.
Bathroom and Toilet Waterproofing Systems We Apply
Mackintosh Corporation evaluates each wet area project individually and applies the most appropriate waterproofing system for the specific conditions. Our bathroom and toilet waterproofing solutions include:
Flexible Cementitious Waterproofing
Flexible cementitious waterproofing is the most commonly applied system for bathroom floors and walls in residential and commercial buildings. It is a two-component cement-based coating that is easy to apply, highly adhesive to concrete and masonry surfaces, and provides excellent resistance to water pressure. Products from the Sika and Davco product lines are used, applied in multiple coats to achieve the required thickness and coverage — including all critical junctions, pipe penetrations, and floor-wall joints.
Liquid-Applied Polyurethane Membrane
For bathrooms requiring high flexibility and crack-bridging capability — such as those in buildings prone to settlement or vibration — Mackintosh applies liquid-applied polyurethane waterproofing membranes. These form a seamless, elastic membrane over the entire floor and wall surface, accommodating minor structural movement without cracking or delaminating.
Epoxy and Polyurethane Injection for Existing Leaks
For existing bathrooms already showing signs of leakage through cracks, joints, or pipe penetrations, Mackintosh uses epoxy and polyurethane injection techniques to stop active water ingress before applying an overall waterproofing membrane. This is especially useful in occupied buildings in Pasig and Mandaluyong where full demolition of tiles is not immediately feasible.

The Mackintosh Bathroom Waterproofing Process
Proper bathroom waterproofing is a systematic process that requires careful preparation and skilled application. Mackintosh Corporation follows a proven step-by-step approach:
- Site Inspection: We assess the condition of the bathroom substrate, identify existing cracks, moisture damage, and plumbing penetration points that need special attention.
- Surface Preparation: All surfaces are cleaned, existing loose material removed, and cracks are filled and repaired before waterproofing is applied.
- Detailing Critical Areas: Special attention is given to floor-wall junctions, pipe penetrations, and drain areas — the most common failure points in bathroom waterproofing.
- Waterproofing Application: The selected waterproofing system is applied in the required number of coats to achieve the specified thickness and complete coverage.
- Curing and Testing: After curing, a flood test is conducted to verify the integrity of the waterproofing membrane before tiles or finishes are installed.
- Final Handover: The completed waterproofed area is handed over with full documentation for the client’s records.

Frequently Asked Questions — Bathroom Waterproofing in Pasig and Mandaluyong
Do I need to remove my existing tiles before waterproofing?
In most cases, yes. For new waterproofing applications, tiles need to be removed to access the substrate and apply the waterproofing membrane directly to the concrete or mortar bed. However, for remedial injection work to stop active leaks in existing bathrooms, tile removal may not always be necessary. Mackintosh will advise the best approach after a site inspection.
How long does bathroom waterproofing take?
A standard residential bathroom waterproofing job in Pasig or Mandaluyong typically takes 1 to 2 days for application, plus curing time before a flood test can be conducted. The total process from surface preparation to flood test clearance is usually completed within 3 to 5 days, depending on the size of the area and the system applied.
What causes bathroom waterproofing to fail?
The most common causes of bathroom waterproofing failure are poor surface preparation, inadequate coverage at critical junctions (floor-wall joints and pipe penetrations), use of substandard materials, and improper application by unskilled workers. Mackintosh Corporation addresses all of these by following strict application standards, using only premium materials, and employing trained waterproofing specialists on every project.
