Build once, build right—why waterproofing should never be an afterthought
Why Waterproofing is Crucial During Construction & Renovation
Whether you're building a new home or renovating an existing structure, waterproofing your main building—especially foundations, terraces, basements, and walls—is one of the most important steps you can take to protect your investment.
Without proper waterproofing:
- Water can seep through roofs, cracks, and joints.
- Moisture weakens concrete, corrodes steel, and damages wood.
- Mold and mildew can develop, posing health risks.
- Repairs later are more expensive and invasive.
👉 Waterproofing at the right time—during construction or major renovation—prevents these issues at the root.
Waterproofing During Construction: Laying a Strong Foundation
Waterproofing starts at the base—literally. Here’s where and how it should be done during the initial building process:
🔹 1. Foundation & Basement Waterproofing
- Method: Use cementitious coatings or bituminous membranes.
- Why: These areas are constantly exposed to groundwater. A moisture barrier is essential to prevent rising damp.
- Products: ACC LeakBlock, Dr. Fixit Pidiproof, UltraTech Flex.
Cover the concrete wall with a cement-polymer waterproofing membrane
🔹 2. Concrete Slabs and Pillars
- Solution: Add integral waterproofing compounds (like polymer-based admixtures) directly into the concrete mix.
- Benefits: Increases water resistance, reduces cracking, and strengthens structural integrity.
🔹 3. Roof Slabs & Terraces
- Action: Apply liquid waterproofing membranes (e.g., polyurethane or acrylic-based) after slab curing.
- Add-on Tip: Ensure slopes for drainage and seal penetrations around vents and pipes.
Polycryl is an easy-to-use acrylic waterproofing coating
🔹 4. Brick and Cement Works
- Apply a waterproof coating or additive while plastering.
- Use high-quality water-repellent cement like ACC Gold Water Shield Cement for enhanced protection.
Waterproofing During Renovation: Fix Now, Save Later
Renovating your main building? Don’t miss these critical steps to upgrade its water resistance:
🏠 1. Terrace or Roof Renovation
- Common Issue: Cracks and leaks from weather exposure.
- Solution: Clean surface → repair cracks → apply flexible polyurethane or acrylic-based waterproofing → topcoat with protective paint or tiling.
🧱 2. Wall Dampness and Paint Peeling
- Sign: Bubbling paint or black mold indicates deep water intrusion.
- Fix: Scrape old paint → apply damp-proof primer or membrane → repaint with waterproof emulsion.
🧱 3. Basement Repairs
- For older buildings, waterproof from the inside out using epoxy injection or polyurethane grout.
- Seal joints and floor-wall junctions.
🧱 4. Plastering & Crack Repairs
- Use 2-component acrylic waterproofing or polymer-modified mortar to treat cracked plaster or aging walls.
Waterproofing Materials Ideal for Construction & Renovation
Type | Best For | Features |
Cementitious Coating | Foundations, basements | Easy to apply, good for new construction |
Bituminous Membrane | Flat roofs, underground walls | Durable, high adhesion |
Polyurethane Membrane | Exposed roofs, balconies | Flexible, UV-resistant |
Acrylic Waterproofing | Bathrooms, terraces, plastered walls | Non-toxic, ideal for renovation |
Epoxy/PU Injection Grout | Cracked basements, wet walls | Seals micro-cracks and penetrates deep |
