Are you living in an old house in Lahore and struggling with seepage, moisture, or roof leakage? Old houses in Lahore hold a charm of their own—spacious rooms, thick walls, high ceilings, and that classic architectural touch that modern houses often lack. But with age comes deterioration, especially when it comes to water seepage, moisture, leakage, and roof damage. And while many homeowners often look for solutions like roof insulation service price in Islamabad to compare options and understand modern protection methods, Lahore’s own challenges remain unique. Because of Lahore’s monsoon season, high humidity, and extreme temperature changes, waterproofing becomes essential, not optional.
This blog explains why old houses face frequent seepage, the best waterproofing treatments available today, and how you can protect your home long-term. Whether you’re dealing with roof cracks, damp walls, bathroom leakage, or basement moisture, you’ll learn exactly what works and how to keep your old house strong, dry, and damage-free.
Why Do Old Houses in Lahore Need Waterproofing?
- Aging Materials
Old cement, plaster, and roofing weaken over time, making the structure more absorbent. - Heavy Monsoon Rains
Lahore’s rainfall causes roofs and walls to expand, crack, and trap moisture. - No Modern Insulation
Older homes lack waterproof membranes, heat-proof layers, and chemical protection. - Cracked Roof Surfaces
Weather damage creates cracks that let rainwater seep into the structure. - Weak Drainage Systems
Old drainpipes overflow or leak, causing wall dampness and seepage.
Common Waterproofing Problems in Lahore’s Old Houses
1. Roof Seepage
Water enters through minor roof cracks, eventually causing ceiling paint to bubble or fall.
2. Basement Leakage
Below-ground rooms trap moisture and can absorb water from the soil.
3. Wall Dampness
Horizontal and vertical dampness often spreads across old brick walls.
4. Bathroom Leakage
Water escapes through floor joints or damaged plumbing lines.
5. Foundation Moisture
Weak foundations absorb groundwater, weakening the structural life of the house.
Best Waterproofing Methods for Old Houses in Lahore
Below are the most effective and long-lasting solutions used by professional waterproofing companies today.
1. Roof Waterproofing
Old roofs in Lahore,especially RCC or brick slab roofs,need immediate waterproofing.
Best Solutions Include:
- Acrylic or Polymer Coating: Creates a protective layer that blocks water absorption.
- Cementitious Chemical Treatment: Seals cracks and strengthens roof surface.
- Bitumen Membrane: A thick, durable layer ideal for heavy monsoon conditions.
- Heat-Proof + Waterproof Coating: Reduces temperature and prevents water damage.
2. Wall Waterproofing for Dampness & Seepage
When old walls absorb moisture, they develop patches, smell, and peeling paint.
Recommended Treatments:
- Chemical Damp-Proof Injection: Stops rising dampness in walls.
- Interior Sealant Coating: Forms a protective layer against moisture.
- Exterior Weather-Shield Coat: Protects from rainwater penetration.
3. Bathroom Waterproofing
Bathrooms in old houses are the biggest cause of seepage because water travels from the washroom into adjacent rooms.

- Chemical Coating Under Tiles
- Floor and Wall Waterproof Membrane
Benefits:
- Stops leakage into ceilings or nearby rooms
- Reduces mould and fungus
- Protects internal plumbing areas
4. Basement Waterproofing

Old houses suffer from foundation moisture if not treated properly.
Best Methods:

Why It’s Needed:
It prevents water from entering through the base of the building, protecting long-term structural health.
6. Crack Repair and Sealants
Old structures often develop long cracks due to temperature changes and foundation settling.
Types of Crack Solutions:
- Epoxy filling
- Polyurethane sealants
- Cementitious crack repair compounds
These prevent water from entering and spreading inside walls or roofs.
