Our Services | Sewer Rehabilitation Contractor Singapore

What We Do

Within our Pipeline Rehabilitation Services, we have different methodologies to rehabilitate
the main lines, sanitary lines and manholes.

Trenchless “No Dig” Technology – CIPP is one of the most common method for rehabilitating pipelines.
CIPP lining method avoids the need to excavate long trenches, which are required for open trench pipe replacement.
Can be used for pumping mains, gravity lines and water mains.
Can be designed as fully or semi-deteriorated conditions based on international design standards

SWL systems can be installed in live flow conditions for gravity pipes only
Usually used where temporary bypass is an issue
SPR™ is made of steel encapsulated PVC mechanical interlocking strips
Applicable to circular and non-circular pipes with diameter / dimension from 450mm to 5000mm.
Able to negotiate longitudinal bends & curvature radius of 5D or above.
SPR™PE is made of HDPE material via automated fusion process, it can be done up to diameter 3000mm for circular pipes only
The use of Steel and HDPE material achieves a liner with high strength and superior chemical resistance. (HDPE is an inert material)
Can be designed as fully- or semi-deteriorated pipe conditions based on international design standards

This method is used for short pipe lengths for prevention of infiltration.
The sleeve liner is a specially designed repair system using inflatable packers wrapped with resin saturated with fiberglass mats impregnated with resin on site.
Construction footprint is small.

Generally this is a process involves pushing or pulling a new GRP pipe into an existing pipe and filling the remaining annular space with non-structural flowable grout.
Can be used for both large diameter gravity and pressure pipelines
Can be manufactured to any shape/dimensions
Can be installed under tidal or high flow conditions
Minimal emissions with low carbon footprint as compared to traditional open cut replacement method.

Use of fibreglass cementitious material to restore structural properties and to prolong asset lifespan
Can be sprayed, hand applied or by centrifugal cast
High corrosion protection properties
Able to resume flow in a short period of time

With rapid urbanization over the years, CCTV pipelines condition survey, which is a non-destructive assessment of the internal condition of the pipelines and culverts, plays an important role in determining the exact location and severity of deterioration for any remedial actions
Able to inspect pipelines of various diameters / shapes
Able to inspect pipelines of diameter from 100mm to 3000mm

Sewer flow monitoring is used to assess and predict the flow conditions of sewers.
Data is collected real time
Sewer overflow sensors are used as a sewer overflow alert system via SMS
Both systems help in scheduling cleaning works proactively to prevent chokeages and overflows

Rapid urbanization with the ever-changing land use has placed tremendous strain on many existing systems which have been in use for many years. Regular preventative maintenance has to be done to maintain the pipelines at its optimal capacity. This in turn would slow down the deterioration process hence prolonging the asset lifes.
Able to provide high pressure cleaning systems from 10,000psi to 40,000psi and high flow cleaning systems from 150L/min to 350L/min

Rubber dam is a type of tidal control structure for flood control or other tidal control purposes
No vertical permanent supports are needed
Installation is quick and cost effective as compared to other permanent structures
Old Bridgestone designed Rubber dam have risk of delamination over the years.
With new design and technologies, which have side-seam protectors and abrasion indicators the lifespan the rubber dams can be prolonged.
