Give Your Old Building Protection Against Water Damage
Old buildings often develop cracks, damp walls, terrace leakage, peeling paint and water seepage due to ageing, weather exposure and damaged waterproofing layers. If left untreated, even a small leakage can gradually damage plaster, walls, ceilings and concrete surfaces.
SeelanRoko provides professional old building waterproofing and leakage repair solutions designed to identify the source of water intrusion and treat the problem with the right waterproofing method.
From terrace and roof leakage to bathroom seepage, exterior wall dampness and cracks, we help restore your building’s protection and reduce recurring leakage problems.

Understand the cause
Why Does an Old Building Need Waterproofing?
As buildings age, waterproofing layers deteriorate and surfaces become more vulnerable to rainwater and moisture. Cracks in terraces, walls, joints and concrete can allow water to penetrate deeper into the structure.
Common reasons for water leakage
- Cracks in terrace and roof slabs
- Water stagnation and poor drainage
- Bathroom and kitchen seepage
- Damaged tile joints
- Weather-related surface deterioration
- Damaged waterproofing layers
- Exterior wall cracks and porosity
- Leakage around pipes and joints
- Rising dampness
- Porous concrete and plaster
The visible damp patch inside your home may not always be the actual source of leakage. Proper inspection and diagnosis are important before selecting a waterproofing treatment.
Warning signs
Signs Your Old Building Needs Waterproofing
💧 Damp Walls
Persistent damp patches can indicate seepage through walls, bathrooms, roofs or plumbing areas.
🏠 Terrace Leakage
Water stains after rain may point to cracks, damaged waterproofing or water accumulation.
🧱 Wall Cracks
Small cracks can allow rainwater to enter the wall and gradually increase moisture damage.
🎨 Peeling Paint
Paint bubbling, peeling or discoloration may occur when moisture becomes trapped behind the surface.
⚫ Black Spots & Fungus
Continuous moisture can encourage black spots, algae and fungal growth on damp surfaces.
🧂 White Salt Deposits
White powdery deposits, known as efflorescence, can appear when moisture moves through masonry or concrete.
Our Services
Old Building Waterproofing Solutions
At SeelanRoko, waterproofing is planned according to the source of leakage, surface condition and severity of the problem.
Terrace & Roof Waterproofing
Terraces are one of the most exposed parts of a building. Rainwater, cracks, ponding and ageing waterproofing layers can eventually cause leakage into rooms below.
Our terrace waterproofing solutions can address:
✓ Terrace cracks
✓ Roof leakage
✓ Water ponding
✓ Ceiling seepage
✓ Damaged waterproofing
✓ Parapet wall leakage
✓ Joint and edge leakage
Exterior Wall Waterproofing
Exterior walls continuously face rain, sunlight and changing weather conditions. Cracks and porous surfaces can allow water to penetrate into the building.
We help address:
✓ Rainwater seepage
✓ Exterior wall cracks
✓ Damp patches
✓ Peeling paint
✓ Surface porosity
✓ Algae and black spots
Bathroom Waterproofing
Bathroom leakage can affect adjoining walls, ceilings and rooms on lower floors.
SeelanRoko can help with:
✓ Bathroom floor leakage
✓ Wall seepage
✓ Tile joint leakage
✓ Plumbing-area seepage
✓ Dampness around wet areas
Kitchen Waterproofing
Water exposure around sinks, plumbing connections and wet areas can eventually result in dampness and seepage.
Our solutions help address moisture-related problems around:
✓ Kitchen walls
✓ Sink areas
✓ Pipe connections
✓ Floor joints
✓ Wet areas
Water Tank Waterproofing
Damp patches, peeling paint, black spots and efflorescence on interior walls can indicate moisture entering from another area.
Instead of simply repainting the affected wall, the source of moisture should be identified and treated.
Water tanks are constantly exposed to moisture and water pressure, making them prone to cracks, seepage, and leakage over time. SeelanRoko Water Tank Waterproofing helps seal vulnerable areas, reduce water seepage, and protect surrounding walls and surfaces from dampness.Common Problems We Solve:
✓ Water tank wall leakage
✓ Cracks and seepage
✓ Dampness around the tank
✓ White salt deposits (efflorescence)
✓ Water seepage into nearby walls
✓ Waterproofing deterioration
Basement Waterproofing
Basements are highly vulnerable to groundwater, foundation moisture, and water seepage through walls and floors. SeelanRoko Basement Waterproofing provides effective protection against moisture infiltration, helping keep your basement dry, cleaner, and better protected from long-term dampness.
Common Problems We Solve:
✓ Damp basement walls
✓ Water seepage through floors
✓ Wet floor edges and corners
✓ Groundwater moisture
✓ Musty smell caused by persistent dampness
✓ White salt deposits on walls
✓ Recurring leakage and seepage
Interior Wall Dampness Treatment
Damp patches, peeling paint, black spots and efflorescence on interior walls can indicate moisture entering from another area.
Instead of simply repainting the affected wall, the source of moisture should be identified and treated.
Crack Repair & Waterproofing
Cracks can become pathways for water penetration.
Depending on the type and severity of the crack, appropriate crack filling, sealing and waterproofing treatment can be carried out.
How we work
Our Old Building Waterproofing Process
01
Site Inspection
Our team examines the affected area and looks for visible cracks, dampness, water stains, drainage issues and other possible sources of leakage.
02
Identify the Leakage Source
The visible leakage point is not always the actual entry point of water. We assess the surrounding areas to determine where moisture may be entering.
03
Surface Preparation
Loose plaster, dust, damaged coating, algae and other surface contaminants are removed wherever required so that the waterproofing treatment can bond properly.
04
Crack & Damage Repair
Cracks, joints and damaged surfaces are repaired and sealed using a suitable repair method before waterproofing.
05
Waterproofing Treatment
The recommended waterproofing system is applied according to the surface condition, affected area and leakage problem.
06
Curing & Final Inspection
The treated area is allowed to cure properly, followed by a final inspection to check the completed waterproofing work and overall surface condition.

| Parapet Walls | Rainwater penetration |
| Joints & Cracks | Water entry |
Don't Just Paint Over Damp Walls
Dampness is a symptom — not always the source of the problem.
Simply repainting a damp wall may temporarily improve its appearance, but if water continues to enter from the terrace, exterior wall, bathroom or another source, the problem can return.
That’s why SeelanRoko focuses on finding the possible source of water seepage first and then selecting the appropriate repair and waterproofing treatment.
Old Building Waterproofing FAQs
How do I know if my old building needs waterproofing?
Signs include damp walls, terrace leakage, ceiling stains, peeling paint, cracks, fungus, efflorescence and recurring water seepage.
Can an old building be waterproofed?
Yes. Waterproofing can be carried out during repair and renovation of older buildings. The appropriate method depends on the building’s condition and the source of leakage.
What causes water leakage in old buildings?
Common causes include ageing waterproofing, cracks, damaged joints, poor drainage, water ponding, porous surfaces and leakage from wet areas.
Can waterproofing stop wall dampness?
Waterproofing can help control dampness when the treatment addresses the actual source of moisture. A site inspection is recommended to determine the cause.
How can I stop terrace leakage in an old building?
Terrace leakage may result from cracks, damaged waterproofing, poor drainage or water accumulation. The terrace should be inspected before selecting a repair and waterproofing method.
Can bathroom leakage damage the ceiling below?
Yes. Water from a bathroom can travel through floors and slabs and appear as dampness or stains on the ceiling below.
Is waterproofing required before repainting an old building?
If dampness or leakage is present, the moisture problem should be addressed before repainting. Otherwise, paint may peel or develop stains again.
How much does old building waterproofing cost?
The cost depends on the affected area, surface condition, leakage source, repair requirements and waterproofing system selected. SeelanRoko can provide an estimate after assessing the site.
