Basement & Foundation Waterproofing Costs in Singapore

Waking up to a flooded basement is a nightmare for homeowners. Water leaks and excess moisture from the foundation can weaken your building’s structure and lead to costly repairs. Many homeowners ignore concrete cracks, assuming that repairs are too expensive. However, addressing cracks early is far more affordable than waiting for major structural damage. Left untreated, these cracks can worsen, leading to mold growth, higher repair costs, and a lower resale value.

At Waterproofing Singapore, we provide cost-effective solutions to prevent foundation damage and keep your home dry and secure.

Waterproofing Repair Methods & Costs

Each waterproofing method is designed for different types of cracks and damage levels. Below are three industry-approved techniques:

1. Epoxy Crack Injection

• Epoxy resin is injected into the basement crack, creating a permanent waterproof seal.
• It bonds with concrete, reinforcing the structure and preventing leaks.
• This method takes 4-5 hours to cure fully.
• More affordable than excavation-based repairs.
• Ideal for structural cracks in concrete foundations.

2. Polyurethane Crack Injection

• Polyurethane is injected at low pressure, filling cracks and preventing water seepage.
• It expands and seals leaks, even if the surface is damp.
• Suitable for both residential and commercial buildings.
• A cost-effective, non-invasive repair method compared to excavation.
• Offers flexibility and adapts to minor movements in the foundation.

3. Exterior Crack Repair

• Requires excavation around the foundation to seal cracks from the outside.
• More expensive due to labor, depth of digging, and accessibility challenges.
• The most comprehensive solution for preventing basement water intrusion.
• Ideal for severe water leakage problems affecting multiple areas.

Factors Affecting Waterproofing Costs

1. Size & Number of Cracks

• Repairing multiple or larger cracks increases costs compared to a single small crack.
• Discounts may be available for multiple repairs.

2. Follow-Up Services & Warranties

• Quality waterproofing services include follow-ups to ensure long-term effectiveness.
• Repairs with warranties may cost more upfront but save money in the long run.

3. Excavation vs. Non-Excavation Repairs

• Epoxy and polyurethane injections are cost-effective as they don’t require excavation.
• Exterior repairs are pricier due to the additional labor and materials required.

4. Urgency of Repairs

• Emergency waterproofing services may carry additional costs.
• Scheduling repairs in advance can help you save on service fees.
