Why do homes have water leakage and seepage problems?

Brand-new properties should not have water leakage or seepage problems if they are built right. However, as these properties aged, repair and maintenance become necessary. Homeowners need to take note of any water leakage or seepage issues in the house. When such problems are first noticed, call in an expert to take over so that there will be less disruption to your daily life.

What are the water leakage and seepage problems faced by homeowners?

 Typically, homeowners are faced with the following concerns in their homes:

  • Wall Leakage and Seepage
  • Ceiling Leakage and Seepage
  • Roof Leakage and Seepage

In a landed property, homeowners are presented with an additional two issues:

  • Structural Leakage and Seepage
  • Architectural Leakage and Seepage

What is the most common leakage problem in Singapore?

The primary leakage issues faced by Singapore homeowners are cracks in their internal and/or external walls. While some contractors may tell homeowners that evacuation is necessary, we at Le Fong, have a better solution for you – Polyurethane (PU) Crack Injection.

What is a PU Crack Injection?

 A PU Crack Injection is a kind of repair work and waterproofing technique that is applicable only to poured concrete structures. The method makes use of a pressurised injection of resin (a type of waterproofing material) into a foundation crack. The pressure of the injection ensures that the entire crack is filled. That efficiently eliminate the crack and prevent water from coming into the house through your ceiling or basement.

This is the best solution for a crack found in a poured concrete wall. It is also economical as a form of repair work for a leaking concrete wall in your house or basement.

LE FONG IS WELL-KNOWN AS THE CONCRETE CRACK INJECTION SPECIALISTS IN SINGAPORE AND OUR NEIGHBOURING COUNTRIES.

As the indisputable leaders in the domain of pressurised injection services for concrete crack repair and crack injection in residential, commercial and industrial properties, we are the experts for any of your water leakage or seepage problems due to cracks on your internal and/or external walls.

Our experienced specialists are the leaders in the industry because of four key reasons.

  1. We use only the latest technology and techniques
  2. We use highly-customised equipment that is not found in the market
  3. We have a variety of materials available to us and use only the most appropriate one for each job. We do not believe in a “one size fits all” mentality.
  4. We rigorously trained our new technicians before they are qualified to work alongside our experienced experts in the PU Crack Injection team.

We are the rescue team for water leakage and seepage issues. Even some of our competitors come to us when they are not able to solve the problem on their own.

Le Fong has proven our expertise in handling any cracks in the concrete foundation of your ceiling, basement or any other underground structure with all the success of our PU Crack Injections behind us.

Bitumen/asphalt compound modified with SBS and high tack resins. This special compound has been formulated to make the product easy to install. The membrane can be adjusted should it initially be placed in the wrong position, as the adhesive on the sheet achieves final adhesion only after a few minutes.

Protective film
This is hot-laminated to the bituminous/asphalt compound and gives the membrane its mechanical and physical characteristics, such as heat stability, shape, chemical resistance, etc.

Features & Benefits
Cold Application: installed without the use of open flames. Ideal for installation in restricted spaces.
Chemical resistance: the protective polymer film is highly resistant to acids, alkalis and other pollutants.
Flexibility and adaptability: this membrane will adapt easily to irregularly shaped surfaces, and will stretch up to 9% without breaking or cracking.

Self sealing: the membrane self seals on contact maintaining its watertightness.
Constant thickness: the membrane is manufactured using high-tech machinery which constantly monitors its thickness, and ensures that the films and synthetic materials are manufactured to the highest specifications and quality control requirements.High bi-axial strength cross-laminated polyethylene reinforcement film.

• Self-adhesive

Common Leakage Problem and Solutions

Main leakage problems are cracks on internal or external wall. We provide (PU) Crack Injection solution to home owners.

Le Fong we are well known among homeowners, waterproofing contractors, renovation contractors, and property managers in the Singapore, and surrounding areas, as the “Concrete Crack Injection Specialists” because we are the indisputable leaders in the domain of pressurized injection services for concrete foundation crack repair / foundation crack injection in both residential and commercial applications.

Our TEA, are veritable specialists in both epoxy crack injection and polyurethane injection for four key reasons:
• We use the latest technologies and techniques;
• We use highly customized equipment;
• We use a variety of epoxies and polyurethanes that are the most appropriate for a given application; and
• Our technicians undergo rigorous training before they can qualify to become journeymen and injection technicians.

With many of successful injections behind us, we have proven that we are able to handle the concrete foundation crack in your wet basement or any other cracked concrete underground structure.

What is a polyurethane (PU) crack injection?

PU injection involves concrete crack repair and basement waterproofing techniques which are only applicable to poured concrete structures. Crack injection, or “pu injection, is used in the following applications:
• To repair water seepage from concrete cracks of virtually any size in poured concrete walls or ceilings;
• To permanently seal actively leaking cracks;
• To repair basement cracks that have been previously repaired by injection or some other basement waterproofing technique; and
• The repair of cracked poured concrete structures in general.
Be sure to check out our waterproofer tips on finishing your basement.

How does crack injection work to fix water seepages?

PU injection involves the pressurized injection of either epoxy or polyurethane resin into a foundation crack; these injections are referred to as epoxy crack injection and polyurethane crack injection. The injection pressures ensure that cracks are filled through the entire thickness of a ceiling wall which is typically 200-300cm thick, thereby effectively eliminating the crack and keeping water on the exterior of the foundation where it belongs so that you no longer have water in your basement. This type of concrete crack repair is all that is needed to accomplish basement waterproofing when a poured concrete crack is leaking, or if there is a concern that an existing crack may leak in the future. Pressurized crack injection is also the most economical means by which to repair a wet, leaky poured concrete basement; in reality, it is rarely necessary to excavate a poured concrete foundation wall.

Excavating and waterproofing a foundation is expensive and destructive. Crack injection is an effective and inexpensive way to put an end to foundation leaks and that wet basement
