How to properly waterproof your Landed Property (Singapore)
Waterproofing a landed property in Singapore involves several steps to protect the building from the country's humid climate and frequent rain. Here are the key steps to ensure effective waterproofing:
1. Inspection and Assessment
Identify Problem Areas: Inspect the property thoroughly to identify areas prone to water leakage, such as the roof, walls, basement, and bathrooms.
Assess Damage: Look for signs of water damage, such as mold, mildew, damp spots, and cracks.
2. Roof Waterproofing
Clean the Roof: Remove debris, dirt, and old coatings.
Repair Damages: Fix any cracks or damaged tiles.
Apply Waterproofing Membrane: Use a waterproofing membrane or coating that is suitable for Singapore's tropical climate. Materials like bituminous membranes, liquid-applied membranes, or polyurethane coatings are commonly used.
Ensure Proper Drainage: Make sure gutters and downspouts are clear and functioning properly to direct water away from the roof.
3. External Walls Waterproofing
Surface Preparation: Clean the walls and repair any cracks or damages.
Waterproof Coating: Apply a waterproof coating or sealant designed for external walls. Elastomeric paint is often used due to its flexibility and durability.
Check Seals: Ensure that all window and door seals are intact and properly sealed with waterproof sealant.
4. Basement Waterproofing
Interior and Exterior Sealing: Waterproof both the interior and exterior walls of the basement. Use a combination of waterproof membranes, coatings, and sealants.
Install Sump Pump: Consider installing a sump pump to manage groundwater and prevent flooding.
French Drains: Install French drains around the perimeter to channel water away from the foundation.
5. Bathroom Waterproofing
Use Waterproof Membrane: Apply a waterproof membrane to bathroom floors and walls, especially in shower areas.
Seal Joints and Corners: Use waterproof sealants on all joints, corners, and areas around fixtures.
Quality Tiles and Grout: Use high-quality, water-resistant tiles and grout.
6. Balcony and Terrace Waterproofing
Clean and Prepare Surface: Remove any old coatings and repair cracks.
Apply Waterproof Coating: Use a waterproof coating or membrane designed for outdoor areas.
Proper Drainage: Ensure that the balcony or terrace has proper drainage to prevent water pooling.
7. Regular Maintenance
Routine Inspections: Regularly inspect the property for signs of water damage or leaks.
