Introduction

Dampness is a common but often underestimated issue in Ugandan homes and buildings especially in areas with poor drainage, high rainfall, or improper construction. Left untreated, it weakens structures, causes paint to peel, promotes mold, and can affect your health.

In this article, we dive into what causes dampness, how to fix and prevent it, and introduce effective damp-proofing solutions like MPE proof, LAAP, admixtures, damp seal, and white spirit—with context specific to Uganda’s climate and construction practices.

🔍 What Causes Dampness in Ugandan Buildings?

Dampness can result from multiple factors, including:

• • Poor Foundation Work: Many buildings lack a proper damp-proof course (DPC) during foundation laying.
  • Rising Moisture: Water from the ground moves upward through walls due to capillary action.
  • Leaking Roofs and Gutters: Common during Uganda's rainy seasons (e.g., March–May, October–December).
  • Blocked or Absent Drainage Systems: Stagnant water seeps into foundations and walls.
  • Use of Porous Materials: Some locally made bricks and mortar absorb water easily.

🛠️ How to Fix Dampness in Existing Structures

1. Scrape & Dry Affected Areas

• • Remove any moldy or bubbling paint or plaster.

  • Allow the area to dry completely—this may take several days depending on severity.

2. Apply Damp-Proofing Compounds

Use Damp Seal products that block water molecules while allowing trapped moisture to escape.

3. Inject Water-Repelling Admixtures

Products like MPE proof or LAAP can be injected into the walls or mixed into replastering mortar to act as a chemical DPC.

4. Surface Coating & Painting

After drying and sealing:

• • Use white spirit to clean and prep the wall.

  • Apply high-quality water-resistant paints or coatings.

5. Improve Drainage Around the Building

Create slopes around the foundation or install soak pits to direct water away.

🧱 How to Prevent Dampness During Construction

1. Use a Proper Damp-Proof Course (DPC):

• • A layer of MPE or bituminous felt should be placed at the base of the walls.

2. Incorporate Waterproof Admixtures:

• • LAAP and MPE Proof are locally available chemical admixtures mixed with cement during construction to create waterproof concrete.

3. Mix in Admixtures for Foundation and Slabs:

• • LAAP (Liquid Acrylic Admixture Product) helps create watertight concrete slabs and walls.

  • MPE Proof is commonly used in Uganda to reinforce waterproof properties in mortar and concrete.

4. Cure Concrete Properly:
Improper curing causes cracks, which allow water to penetrate over time. Regular watering and covering during curing help strengthen concrete.

5. Elevate the Foundation:
Avoid low ground levels. The foundation should be high enough to prevent water backflow.

🧪 Materials & Tools to Use in Uganda

⚠️ Common Mistakes to Avoid

• Skipping DPC during foundation

• Painting over damp walls without treating the cause

• Using untreated, highly absorbent bricks

• Ignoring roof and drainage issues

✅ Conclusion

In Uganda’s tropical climate, dampness is not just a cosmetic issue—it can undermine the integrity of an entire structure. Whether you’re a homeowner, builder, or real estate investor, understanding how to prevent, treat, and build against damp using local solutions like MPE Proof, LAAP, and Damp Seal will save time, money, and health.
