Concealed Copper Pipe Repair Without Hacking
Possible causes of pipe leaks:
- Pitting corrosion in copper pipes
- Joint leakages
- External factors such as puncturing or other water-induced corrosion
During the course of the cleaning, we realize that the scrubbing of the pipes internally tends to damage older, more corroded pipes, resulting in pipe leaks. This resulted in us having to hack away walls to repair leaking, concealed copper pipes. Concerned with the inconvenience caused to our clients, we immediately carried out a series of research and discovered a method of pipe repair that does not require the hacking of walls to repair copper pipe leaks and can be completed within a day. This method is the Epoxy Lining.
Since then, we have developed the technique and carried out numerous tests to ensure that the method does not affect the quality of drinking water and have since carried out thousands of repairs to date.

Plumbing, Sanitary, and Gas Services
Water/Air-tightness test required for sanitary plumbing/drainage system
In accordance to the installation requirements layout by the PUB (Public Utilities Board), we refer to PUB's letter ref: WRN/17.2 dated 30th December 2016. All sanitary joints, SWP, & VP have to be tested on site during construction work and Pre-TOP test of new construction:
Every level or floor SWP (Soil Waste Pipe) and VP (Ventilation Pipe) installation are 100% with water/air-tightness. No soil-waste gas can be leaked out of the sanitary/plumbing system.
Two types of test:
We provide the service to support the air-tightness test and also training of workers to carry the test. Sharing our know how to test: Equipment, methodology approach to each common sanitary pipe and fitting seeking leak point (if any by soap-water/smoke or UV-smoke/water)

Two types of test:
- When & how to test high pressure test = 34 kPa or 5 PSI for 15 minutes using pressure gauge
- When & how to test low pressure test = 38mm or 1-1/2" for 3 minutes using manometer

Fire Protection System
Expanding on OSK's familiarity with piping systems, we have also ventured into fire protection systems to explore new ways to apply our knowledge and experience, while learning new systems and techniques at the same time. In doing so, we have enabled ourselves to provide a more wholesome solution to many of our clients.
We have since handled a variety of projects which requires the installation of fire protection systems such as fire hydrants, wet/dry risers, fire sprinklers and fire alarm systems & many more in condominiums, HDB and other public and commercial institutions. These installations are tested and commissioned in compliance with SCDF's Fire Code.

Consultation, Design, and Build
Having accumulated a wealth of knowledge, experiences, and resourced over the years, OSK is now a trusted partner where troubleshooting is required; be it a contractor, consultant, building owner, or even a home owner. We provide relevant, up-to-date advice to our clients on engineering matters, as well as with issues pertaining to statutory compliances. We also recommend the best practices employed by the industry to deliver higher value outcomes.
Tapping on the talents of our in-house draftsmen, not only do they provide 2D drawings, they also provide critical visual aids through 3D drawings, while advising on foreseeable design complications early in the project planning phase. This allows our team to promptly advise and work closer with our clients to overcome architectural and engineering oversights, lapses, and challenges.
Such efforts shall ultimately translate into quality products that are not only aesthetically pleasing but also safe and functional.

Maintenance Services
To support our post-construction services, we have established a team that specializes in providing maintenance services. This team consists of our most experienced technicians to provide fast remedial actions to the most difficult and/or urgent situations. Dedicating such a specialized task force is of utmost necessity since the dynamics and constraints of a built environment differ vastly (usually more challenging) from that of a new construction project.
The services provided by this team include:
- Pipe flushing
- Leak repairs
- Choke clearing
- Water tank cleaning
- Pump repairs and servicing
- Gas pipe inspection
- Additions and alternations
