PMPS Liner Technology

Cured in Place Pipe (CIPP)

  • 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

Spiral Wound Lining (SWL) System

  • 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

Sleeve Lining

  • 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.

Slip Lining (GRP Pipes)

  • 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.

Manhole Rehabilitation

  • 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

CCTV Pipeline Inspection Survey

  • 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
PMPS Liner Technology

Sewer Flow Monitoring

  • 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

High Pressure & High Flow Cleaning Works

  • 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
PMPS Liner Technology

Temporary Bypass Services

  • Serve as temporary bypass services for live flow pipelines
  • To provide dry working conditions in chambers or pipelines 
  • Able to provide pumps from 2” to 12"
  • Availability of pneumatic plugs from diameter 100mm to 1800mm

Replacement of Bridgestone Rubber Dam

  • 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.
