VeriCure® CIPP Curing Monitoring System
VeriCure is a breakthrough curing monitoring system (CMS), built around Fiber-Optic Distributed Temperature Sensing (DTS) technology, designed to improve the CIPP curing process. Its ability to continuously monitor the temperature during the liner installation helps confirm a more complete cure throughout the length of the host pipe. The result is a fully cured, leak-free pipe, rehabilitated with confidence and verified with data.
The use of the Curing Monitoring System enables you to increase the planning reliability of your renovation measure to reduce follow-up costs, energy costs and CO2 emissions.
By using VeriCure, installers are able to address potential concerns in real time, while engineers and owners benefit from improved QA/QC and a CIPP liner installed to spec.
OSSCAD received the German patent in January 2010 and the US and European patent in 2012. On November 20, 2020, Vortex Companies LLC acquired the patents and CMS assets from OSSCAD.
Methods for the rehabilitation of pipe or sewer systems are so-called Cured-In-Place Pipe (CIPP). The CIPP process uses flexible hose carriers made of corrosion-resistant synthetic fibers (needled felt) or fiberglass reinforced plastic composite (GRP fibers) impregnated with a reaction resin molding compound. The installation in the channel takes place via the manholes, in which the hose (liner) is installed either by inversion or by feeder. Curing to a solid plastic pipe (liner) can be carried out by hot curing by means of hot water, steam or by UV light curing.
The structural and operational requirements for renovated sewers are high. The pipe lining processes are under special control and testing, as their production in the field takes place under difficult working conditions. Ensuring a consistent quality standard is verified after the build-up by acceptance tests. Quality defects on the liner at its installation may be caused for instance by local overheating (due to excessive polymerization of the resin, a too high heat supply or a faulty composition) or by an incomplete curing. The detection of abnormalities and their precise localization along the liner makes it difficult to accept and to sample liners. Due to the risk of sinks or inlets of cold groundwater, a safety margin in energy management is taken into account, which often leads to unnecessarily long heating times.
VeriCure® is a breakthrough technology developed to improve the CIPP curing process. Its ability to constantly monitor the temperature throughout the duration of the liner installation helps ensure a 360° cure throughout the length of the host pipe. The result is a fully rehabilitated, leak-free pipe, cured with confidence and verified with data.
Easy to use, the VeriCure optical fiber cable runs along the invert of the host pipe and is activated once the CIPP liner has been inflated and the curing process begins. With the cable plugged into the control box, VeriCure’s CMS software captures and records the thermal temperature, incrementally, along the entire length of the liner. Regardless of existing flow, VeriCure provides highly accurate and localized temperature data; helping ensure every inch of liner is properly cured.
- CMS optical fiber monitors temperature along entire length of CIPP liner
- CMS software verifies the cure and installation
- Achieve full cure in less time
- Reduce labor, equipment, and fuel cost
- Comprehensive real-time and historical data
System components of the CMS system
The CMS controller can be supplied either as a mobile, portable unit for the use in the field or as 19‘‘ version for the installation in the truck of the company installing the liner.
The mobile CMS measurement device contains the under mentioned system components:
- DTS controller
- IPC with keyboard
- CMS software
- Optical connector (BlueBox) for the connection to the sensor cable
- LAN socket, WLan
- Socket for the energy supply
Powerful CMS software
By using the CMS software, the temperature measurement data can be prepared so that the user can assess and control the local and temporal curing process of the liner during the renovation process.
Standard views of the software are the so-called Zone View, the 3D Plot and the Curing View. The 3D Plot and the Curing View serve as proof of quality for a professional rehabilitation. The zone view provides the installer with clear decision criteria for the energy supply, so that the renovation can be completed successfully even on difficult construction sites.
CMS sensor cable
The CMS sensor cable is designed to be drawn from a cable drum directly into the sewer.
To ensure the quickest possible connection of the sensor cable to the CMS controller at the construction site, the sensor cable is pre-assembled with an optical plug, so that the measuring system can be set up and is ready for use in a few simple steps.
Application fields of the CMS measurement system
The CMS measuring system is suitable for the Cured-In-Place Pipe (CIPP) renovation of waste water pipes (sewers) and pressure pipes (drinking water pipes).

Types of CMS sensor cables
Depending on the diameter and the wall thickness of the CIPP liner, and taking into account the chosen curing process (water, steam and UV curing), different sensor cables are available for waste water and drinking water pipes to provide high mechanical protection for the fiber integrated in the sensor cable.
