Common Waterproofing Problems and How to Prevent Them

Common Waterproofing Problems and How to Prevent Them

Water is one of the main silent enemies of any building. It starts creeping in gradually, spreading silently. By the time you realize that there are water patches, peeling paint, or even the development of mold, it’s too late. It doesn’t matter whether you have a private residence, office, cottage, or even commercial structure; waterproofing is not a choice but a structural requirement.

It is very important to understand the common waterproofing problems so that you can protect your property from expensive maintenance and health problems associated with it. We will discuss these in detail in this article.

1. Cracks in Walls, Roofs, and Slabs

Hairline cracks in the concrete, external plaster, or joints can be the beginning of big leakage problems in buildings. They occur because of the settlement of the structure, because of the thermal effects of changing weather conditions, or poor quality of the construction material used in the construction process. The rainwater gets inside and begins to weaken the structure from within.

  • What To Do About It:  Inspect your walls and terrace prior to the arrival of the monsoon season. Use crack-filling materials and elastomeric sealers for hairline cracks. For larger cracks in the structure, it is advisable to use the polymer-modified mortar first and then the waterproofing coating on the entire surface.
  • The Underlying Problem: One of the key causes of water leakage in walls is neglecting small cracks that lead to bigger ones.

2. Roof Leakage and Water Ponding

A flat roof, terrace, or tin shed will quickly become full of rainwater if it is not kept in shape. If the roof is completely flat or covered with mud and debris, rainwater will stay on it for days and gradually eat through the concrete and the interior iron bars.

How to Avoid It: Make sure that your roof has a proper slope that will facilitate the easy passage of rainwater into the outlets. Do not let dirt or other materials obstruct the drainage pathways. Damage to your roof can be avoided by using a suitable waterproofing compound such as APP or liquid polymer.

3. Bathroom and Plumbing Seepage

Water is used constantly in a bathroom and kitchen. Therefore, these areas are perfect for hidden leaks. They often start with loose joints on the plumbing pipes, pinholes in the pipes that can’t be seen, cracked grout on tiles, and a complete absence of a waterproof membrane beneath the floor tiles. The water that is leaking gradually works its way through the surrounding floors and walls, which causes paint to peel and develops a mildew smell.

How to Prevent It: The best prevention for this would be to make all these moist areas waterproof as you tile by using sunken slab waterproofing and grout with epoxy between the tiles. Also, you should be routinely assessing your plumbing once per year and regrouting all the gaps.

4. Peeling Paint, Efflorescence, and Mold Growth

Clear whitish powdery marks, cracks in the paint, and dark patches of mold formation are clear signs of too much moisture being stored in your walls. Besides ruining the look of the interior of your home, these deposits can also cause your home to smell stale and cause you allergies and breathing issues.

How to prevent: Don’t just brush off and repaint the damp wall without handling the cause. Find out the source of the water leak and fix it. Place anti-efflorescence primer on the impacted wall surface, then add weatherproof paint and damp-proof filler on the exterior.

5. Failed or Low-Quality Previous Waterproofing

Several buildings are victims of poorly executed waterproofing due to the use of cheap materials, unskilled workers, or lack of surface preparation. The chemical coatings fail after one season, joints develop, and the problem of seepage becomes much worse than before.

How to Avoid: Use a complete system-based approach of surface preparation, priming, sealing of cracks, application of coating, and protection of the material, rather than just application of a layer of chemicals. Also, use branded waterproofing materials and employ skilled workers to conduct a water ponding test.

Proactive Maintenance Checklist

  • Inspection at the start of each monsoon: Examine terraces, roofs, external walls, and bathrooms.
  • Passage of Water: Keep the balconies, drainpipes and gutters free of any obstruction, if any.
  • Seal the Gaps: Apply good quality silicone sealant to seal up door and window joints as well as outside pipe penetrations.
  • Act Immediately: Attend to moisture problems right away; the longer you leave it, the more you will spend at the end.
