PipeGuard™ Lining Systems for Seismic Retrofit
The earthquake response and rehabilitation of critical piping systems can be enhanced substantially by insitu PipeGuard™ polymeric linings, installed through trenchless construction procedures. Laboratory and independent testing confirms that PipeGuard™ reinforced pipelines have sufficient structural and mechanical properties to resist ground deformation and repetitive axial displacements at cracks and defective joints.
Electronic inspection options are possible after a seismic event
In situ repair can be easily deployed in the event a failure were to occur
Increased ductility allows for greater movement at the joint sections
Provides a continuous monolithic substrate throughout the host pipe
Strong, resilient, flexible, accommodates high levels of ground motion
Liner design and asset planning to reduce liability and client risk
RestoLine’s seismic test results demonstrates numerical simulations for earthquake engineering used to study reinforced piping lined with PipeGuard™ polymeric systems. Models and dynamic test results have been validated to provide an efficient design life calculation to quantify how insitu PipeGuard™ linings will be affected by seismic conditions.
