Rehab and Repair Solutions
Structural Liners for Mains and Laterals
Cure In Place Pipe (CIPP) and fold-and-form PVC offer a trenchless solution for rehabilitating existing pipelines, while minimizing disruption to surrounding areas and traffic flow. A flexible liner is inserted into the damaged pipe, effectively forming a new, jointless pipe within the old one. This process seals cracks, prevents leaks, and restores structural integrity to the pipeline.
Pipe Bursting and Pressure Pipe Rehab
Pipe bursting is a trenchless technique that replaces existing pipes with new HDPE or PVC. This method is particularly useful for replacing severely damaged pipes or when increasing capacity as you can actually upsize during this process. Pressure pipe rehabilitation is completed via bursting, cured in place, or by using flexible fabric reinforced pipe (FFRP).
Manhole & Wet Well Lining and Restoration
Manholes and wet wells face constant exposure to deterioration. Lining and restoration address this by repairing structural damage, effectively sealing leaks, and applying corrosion resistant coatings. This process significantly extends the lifespan of these crucial components, preventing inflow and infiltration, and ensuring the continued efficient operation of the entire system.
Lateral and Main Grouting
Acrylamide grouting is an effective method for sealing leaks and voids in structurally sound pipelines. A pipe joint or lateral connection is first air tested, and if a leak is present, grout is then injected where it congeals to create a air/ watertight seal outside the pipe. This technique provides a cost-effective solution for extending lifespan and reducing future repair frequency.
Shotcrete and Coatings
Shotcrete, a form of sprayed concrete, reinforces and rebuilds structures like wet wells, large tanks, and manholes. It can be used to enhance the structural integrity of vertical structures. Coatings can be used in conjunction with shotcrete or without, to provide a protective barrier against corrosion, chemicals, and abrasion, thus extending the structure lifespan.
