Which basement waterproofing methods have the best long-term success?
Polyurethane crack injection is widely used across several industries that require durable waterproofing and structural integrity solutions.
Exterior Basement Waterproofing Methods
Exterior waterproofing is ideal for new builds or major renovations. Though costly and labor-intensive, it provides 20+ years of protection by blocking water before it enters.
Interior Basement Drainage Systems
Interior drainage is ideal for existing homes with water issues. Perforated pipes along the basement perimeter direct water to a sump pump. Lasting 15–25 years with minimal installation disruption, it effectively manages hydrostatic pressure.
Polyurethane Basement Crack Injection and Repair
Polyurethane crack injection seals leaking cracks and cold joints in basement walls or floors by injecting expanding foam from the inside. The flexible foam adapts to foundation movement, making it ideal for negative-side waterproofing. When applied correctly, it lasts 10–20 years.
Epoxy Basement Crack Injection and Repair
Epoxy-based waterproofing membranes are ideal for interior basement walls in damp environments. Applied as epoxy or cementitious coatings, they form a moisture and vapor barrier that reduces humidity and prevents mold. With proper maintenance, they typically last 10–15 years.
Combine Methods
S&S Remedial basement waterproofing experts recommend combining techniques—such as interior drainage, polyurethane injection, and epoxy injection—for the most successful long-term basement water leak repairs.

Frequently Asked Question
Is polyurethane injection a permanent solution?
Yes—when applied correctly, polyurethane injection offers a long-lasting seal that adapts to structural movement. However, the longevity also depends on the condition of the structure and surrounding environment.
How much does an interior basement waterproofing cost in Brisbane or Gold Coast?
The average cost of waterproofing concrete basement walls or floors for a small project (20–30 sqm) typically ranges between $800 and $3,000, depending on the scope and condition. S&S Remedial offers an obligation-free site inspection, followed by an honest, detailed quotation tailored to your project.

Is Interior Basement Waterproofing Right for My Basement Leaking Problem?
- Best for finished or hard-to-access exteriors – works well when landscaping, driveways, or patios would make exterior work expensive.
- Good for managing water already entering – captures and redirects leaks through interior drains or sump pumps.
- Less costly than exterior waterproofing – generally more budget-friendly for homeowners.
- Effective under hydrostatic pressure – relieves water pressure against basement walls and floors.
How Effective Is Polyurethane Basement Wall Crack Repair for Leaks?
-
Highly effective for wet basement remediation—polyurethane expands when it contacts moisture, sealing the entire crack from inside to outside.
-
Creates a flexible seal—after basement wall crack repair injection, it remains elastic, allowing the wall to shift slightly without reopening the crack.
-
Quick installation—most basement wall crack repair injections are completed in a few hours with minimal disruption.
-
Long-lasting solution—when properly installed, can last decades without needing reapplication.
How long does it take to waterproof basement walls or floors?
Most S&S Remedial wet or dry basement waterproof solutions are completed in 1 to 3 working days, depending on the scope of the project.
Do I need a licensed waterproofing contractor for basement leaking problem?
Yes, in Queensland, you do need a licensed waterproofing contractor for concrete injection work—especially when it’s part of a waterproofing system.
🛠️ Why Licensing Matters
- Compliance with Australian Standards: Waterproofing work must meet standards like AS 3740-1994, which governs waterproofing in wet areas.
- Building Code Requirements: Waterproofing is considered a regulated building activity under the Queensland Building and Construction Commission (QBCC).
- Insurance and Warranty: Licensed contractors typically offer workmanship guarantees and are insured, which protects you if something goes wrong.
