5 Best Basement Waterproofing Services in Singapore to Keep Leaks Out

Inspection Methods: Good contractors don’t play guessing games with leaks. We prioritised teams using tools like thermal imaging and moisture meters to pinpoint where water’s getting in.

Service Scope: Not every leak needs the same fix. We looked for companies offering options such as exterior excavation, interior drainage, sealing, and coatings instead of one-size-fits-all solutions.

Contractor Credentials: Basement work can affect more than a damp wall. We favoured experienced specialists and construction companies with relevant BCA registration or credentials.

Warranty Terms: A solid repair should come with solid backup. We checked for clear written warranties covering workmanship, materials, or both.


A basement puddle can turn a normal day into a full-blown headache. In Singapore’s wet climate, damp walls and musty smells rarely stay small problems for long.

Leaks can creep through cracks, joints, and weak spots before anyone notices. Waterproofing and grout services help seal those trouble zones before mould and damage move in.

But the best basement waterproofing in Singapore tackles moisture at the source. We looked at specialists who can help keep below-ground spaces drier, safer, and much easier to live with.

How much does basement waterproofing cost in Singapore?

The average total cost for comprehensive basement waterproofing in Singapore generally ranges from SGD 3,000 to SGD 10,000+, depending heavily on the project size, the severity of the water ingress, and the chosen application method.

Waterproofing MethodEstimated Cost Range (SGD)Pricing Metric
Polyurethane (PU) Injection / GroutingSGD 150–SGD 500Per injection point/crack
Epoxy & PU Crack RepairsSGD 400–SGD 800+Per square metre of crack
Basement Injection (Linear)SGD 700–SGD 1,500Per linear metre
Sheet Membrane InstallationSGD 6.00–SGD 8.00Per square foot

Hours: 24/7

WaterproofSG is a handy pick when a basement leak needs more than a quick patch-and-pray fix. Its range includes drainage systems, sump pumps, waterproofing membranes, grouting, sealing, and concrete crack injection.

That broad toolkit means the team can match different methods to different moisture problems instead of leaning on one standard treatment. 

Being open 24/7 is another plus when water decides to show up well outside office hours.

One thing to keep in mind is that the company covers a fairly broad range of waterproofing work, from crack injection to drainage and sump-pump systems. 

For a small leak, it’s worth making sure the proposed solution matches the scale of the problem before proceeding.

Pros

  • Open 24/7, seven days a week
  • Broad range of waterproofing solutions
  • Offers drainage, sump pump, membrane, grouting, and crack-injection work
  • Can handle both water-management and sealing approaches

Cons

  • Smaller leak repairs may still require careful scoping

“Mark personally came to do site inspection”

Mark personally came to do a site inspection, assessed each leaking case and provided optional solutions for resolving them based on our preferences and budget.
The workmen were able to work independently, co-ordinate with Mark and keep us posted so we are always updated on the progress of the rectification and completion.

3. Pro Waterproofing Singapore PTE. LTD

Address: 420 Ang Mo Kio Avenue 10, #11-1131
Contact: +65 8305 4727 | [email protected]
Hours: Monday–Saturday, 9 AM–9 PM

Pro Waterproofing Singapore doesn’t rely on just one way to deal with basement leaks. 

Its exterior options include excavation with bituminous or polymer-based membranes, while interior methods can involve sealants, French drains, and sump pumps.

That gives homeowners more flexibility when access, leak location, or site conditions rule out a single approach. 

Basement waterproofing is one of the company’s listed services, so the team covers both barrier-style protection and interior water management.

The catch is scheduling. Pro Waterproofing is closed on Sundays, so consultations, site visits, and follow-ups need to be planned between Monday and Saturday.

Pros

  • Offers both exterior and interior basement waterproofing methods
  • Uses bituminous or polymer-based membranes for exterior work
  • 
  • Flexible approach for different leak and access conditions

Cons

  • Closed on Sundays

4. Proseal Contracts Pte Ltd – Waterproofing Company

Address: 20 Ang Mo Kio Industrial Park 2A, #04-17 AMK Techlink
Contact: +65 6483 3009 | +65 8688 8600 | [email protected]
Hours: 24-hour hotline 

Proseal is a strong fit when water is actively pushing through concrete cracks rather than merely leaving a damp patch behind. 

Its PU injection work targets basement walls, lift pits, and other leak-prone concrete areas, and the company is BCA-registered under CR13 for waterproofing installation.

The team takes a fairly methodical approach before pricing the job. 

Site inspections come first, and quotations can spell out preparation, primers, system type, materials, and dry-film thickness, with written warranty terms covering materials and workmanship.

Convenience might be an issue, though. Proseal requires an on-site inspection before issuing a firm quotation, so you won’t be able to lock in an exact price remotely.

Pros

  • BCA-registered under CR13 for waterproofing installation
  • PU injection suited to active leaks in concrete cracks
  • Handles basement-wall and lift-pit leakage
  • Detailed quotations can cover preparation, materials, system type, and dry-film thickness
  • Written warranty terms for materials and workmanship

Cons

  • Firm quotations require an on-site inspection
  • Exact pricing can’t be confirmed remotely

Customer Reviews

“It started with waterproofing the roof”

We engaged the company from 24/8 to 13/9/2026.
It started with waterproofing the roof as we are preparing to install solar panels.

In these 2 weeks, we were blessed to have 3 excellent workers who braved the heat to complete the tasks and achieve 100% foolproof workmanship.

In addition, they took on additional jobs like painting the whole house at a good price.
The manager, Mr Jerald, is always there to answer my queries.
They are very reliable and honest too.

Contact: +65 6226 6116 | [email protected]
Hours: 24/7 

Flux takes the guesswork out of leak hunting, which is a good start when water keeps turning up where it shouldn’t. 

The team uses FLIR thermography, ultrasound, pressure testing, and moisture checks to narrow down the likely source before recommending repairs.

It’s BCA-registered under CR13 Grade L1 and offers free site visits before work begins. Depending on the problem, solutions can include cementitious waterproofing, PU injection grouting, and other targeted repair methods.

That said, one thing to watch is response time for online enquiries, even with 24/7 availability. 

Flux notes that website submissions may take one to two working days, so urgent cases are better handled by phone.

Pros

  • BCA CR13 Grade L1 registered contractor
  • Uses FLIR thermography, ultrasound, and pressure testing
  • Free site visits before work begins
  • Offers cementitious waterproofing and PU injection grouting
  • Diagnostics-first approach helps narrow down likely leak sources

Cons

  • Website enquiries may take one to two working days
  • Urgent cases are better handled by phone
