Fibrwrap Lebanon: Pipelines and Liquid Storage Structures

Fibrwrap Rehabilitation Systems (FRS®) consist of specially developed and environmentally friendly materials to satisfy the need for repair of pipes (concrete, steel) and liquid storage structures.

Pipelines and liquid storage facilities are in constant need for maintenance and cost effective working condition.

Fibrwrap® has developed systems which not only satisfy the requirements for repair, rehabilitation and insulation but also comply with the most stringent environmental specifications for composite materials in unison with liquids and especially drinking water networks.

Furthermore, especially for pipe rehabilitation, Fibrwrap is using the FRS®, a trenchless technology method for the repair, strengthening and retrofit of corrosion-damaged and distressed large-diameter PCCP, RCCP, and steel pressure pipelines used in municipal, industrial and other facilities.

Although the above trenchless methods are developed so that owners avoid any hassle, they can also be used externally on pipes, thus allowing the facilities to operate normally even though the repair works are in progress.

Decades of continuous service of large diameter buried pressure pipelines have led to deterioration that threatens their structural integrity. These water transmission lines or large diameter pressure pipes can be strengthened using the FRS® either internally or externally.

The owner benefits substantially from the small FRS® application time, hence from the minimum down time of their systems.


  • Increase of available hoop strength (increase internal pressure capacity)
  • Damage/leak remediation and prevention
  • Protection from corrosion and rectification of the strength losses (due to corrosion)
  • Increase of bending strength
  • Increase of compression strength due to external loading
  • Seismic upgrades
  • Upgrade of pressure and flow
  • Emergency repairs
  • Structural repair (internal or external) of pipeline networks of medium to large diameter from reinforced concrete, steel and ductile iron
  • Repair and strengthening of liquid storage structures (walls and slabs of a tank)
  • Relining of existing pipelines
  • Joint and transition zone waterproofing and protection of pipes exposed to wear, corrosion and sulfide attack.
  • The FRS® is based on trenchless technology that provides full structural repair
  • Thoroughly tested at independent laboratories
  • Cost-effective
  • Extends the service life of existing structures
  • Significantly lowers the corrosion rate by confining existing members
  • Prevents the onset of corrosion when applied to new structural elements
  • Can be used on circular, square, rectangular, hexagonal, flared and alternative-shaped cross sections with negligible shape and size modifications
  • Specialty scaffolding is designed to span the spool length to allow access to the entire pipe face.
  • People and material access is through existing manholes
  • Provides a US National Sanitation Foundation (NSF) listing for usage in potable water environments.
  • The TYFO® Fibrwrap® System (TFS®) is a patented system (US patent # 5,931,198) that has been successfully utilized worldwide to rehabilitate pipelines
  • Trenchless technology
  • Design, application and monitoring of the project from day one
  • Cost and time effective proposals and applications
  • Minimum disturbance to the everyday activities of the client
  • Ability to repair pipelines externally without interrupting their operation
  • Environmentally friendly solutions
