Wall Seepage Treatment: Stopping Damp, Salt and Peeling Paint for Good

Seepage shows up as a damp patch that keeps growing, paint that bubbles and white salt on the wall. Repainting hides it for a season. Treating the source stops it.

The source is usually a bathroom on the other side, a leaking pipe inside the wall, rain coming through an outside wall or moisture rising from the ground.

Why it happens in Pakistani homes and buildings

Bathroom and kitchen plumbing inside walls, cracked external render, a water tank overflow and rising damp from the soil are the common causes in Pakistani houses. Each needs a different treatment, which is why a visit comes first.

Signs you need wall seepage treatment

• Bubbling or peeling paint on one wall
• White salt deposits
• A patch that grows after the bathroom is used or after rain
• Musty smell in a room

How Shield Agro does wall seepage treatment

1. Diagnosis. We inspect both sides of the wall, check bathrooms and pipes above, and identify the water path.
2. Fix the source. Failed joints, leaking pipes, cracked plaster or missing bathroom waterproofing are repaired.
3. Wall treatment. Damaged plaster is removed and a waterproofing coat or injection is applied.
4. Drying and refinishing. The wall is allowed to dry, then re-plastered and finished ready for paint.

What is included

• Source diagnosis on both sides of the wall
• Bathroom and kitchen joint waterproofing
• External wall crack repair
• Waterproof coat or injection at the source
• Plaster repair and refinishing

What does wall seepage treatment cost in Pakistan?

Wall Seepage Treatment is priced on site after a free inspection. Priced by the wall area and the cause found at inspection. There is no call-out charge, and the price we agree is the price you pay.

How to keep the problem from coming back

• Fix the leaking tap or joint first; no coating survives a live leak
• Check the external wall for cracks before the monsoon
• Keep the ground level below the damp-proof line
• Treat before repainting, not after

Frequently asked questions

Why does the damp come back after painting?

Because paint seals the surface while water keeps arriving from behind. The moisture pushes the new paint off within months. The water source has to be stopped first, and then the wall needs time to dry before it is refinished.

Will you have to break the bathroom tiles?

Not always. Many bathroom seepage problems are at the joints and can be fixed by regrouting and sealing with a waterproofing layer. Where the waterproofing under the tiles has failed, some tiles do need lifting, and we will tell you which before starting.

How long does the wall take to dry?

Days to weeks depending on how wet it was and the season. We refinish only when the wall reads dry, because plastering over a wet wall just moves the problem.
