FAQ

With relining you can renovate cracked or damaged sewers without having to replace the entire pipe. This means you don’t need to do any costly and damaging excavations to access the pipe. It works by inserting a liner coated with resins, then forcing it to the sides of the old pipe with the use of compressed air. Once it’s cured you have a brand new pipe within the old one. This process is faster, more cost effective and have less impact on the residents than traditional renovation techniques.

1. Faster and more profitable installations.
2. One component chemistry (no stress, no waste).
3. Goes through multiple 90 degree bends in a 100mm pipe. 
4. Automatic documentation.
5. 40-100% stronger end result.
6. Do repairs and maintenance by yourself on site.
7. Easy-to-use touch screen system interface.

After a completed renovation, the pipe has regained its static load bearing capacity as well as waterproof integrity and surface smoothness comparable to installing a new pipe by digging and replacing.

Our system is developed for relining all types of lateral wastewater pipes in dimensions from 100mm to 250mm. The material of the installation to be renovated does not matter, since a new pipe with its own structural integrity will be created on the inside of the old pipes. Therefor this reliningsystem is suitable for use in pipes made of concrete, iron, plastic etc.

No. The system has an integrated video feed system, for locating the light head inside the liner while pushing it in and at the same time inspect the liner before curing. It also documents the curingprocess for quality control purposes.

An installation with the UV Relining system has a lifespan of approx. 50 years.

This system has been developed to minimize downtime in the event of a broken part. All components have been designed so they can be replaced quickly on site. To ensure a stabil and reliable system with minimum breakdowns, this unit requires some minor maintenance procedures including cleamning the lightpanels daily and cleaning the wheels on the pullunit monthly.

Yes. Our system is designed so that you can make all maintenance and repair on site, to minimize downtime in the event of a broken part.

Our LED light panels have a lifespan of up to 100 hours. Keep in mind that the life of the panels can be reduced due to dirty panels or insufficient cooling.

The shelf life of our vinylester chemistry is 6 months when stored in buckets at normal room temperature (max 25°C).

The shelf life of our impregnated liner is 1 months when stored at normal room temperature (max 25°C).

Impregnated liners should be stored at max 25°C, well protected from UV light.

Our liner is made of fibreglass.

Due to the use of fibreglass instead of the traditional we achieve a substantially more durable pipe renovation. Tests have shown that the strength (E-module) is increased by between 40-100% with our material in comparision with traditional relining materials.

Since the UV light travels easier through glas this liner ensures a fully cured liner at a much faster speed, every time!

No. When installing with UV Relining system, there is minimal disturbing effects on the residents/tenants due to the use of our odor-free vinylester chemistry. 

Yes.

No, when following the standard operating procedure, the installation of this liner is very safe. Our special vinylester is not classified as dangerous goods, has no strong or toxic fumes, and has not shown to be allergenic when in contact to skin. You will not need to use a mask when installing this, but we do recommend using safety glasses.

The system has a curing speed between 30-40m when installing 150mm liner. Compared to normal epoxi resin systems, the UV Relining solution is from 2 times up to 5 times faster. 

Yes. Although, keep in mind that the impregnation procedure has to take place in an UV-protected enviornment.

Yes. The whole installation process is documented on a Compact Flash memory card, including videofeed,
installation settings, temperature and preassure measurementsalong with curing speed. This simplifies finalizing of the project as well as quality controls later on.

Compressor requirements:
1000l/min at 6-8bar. Air hose should be minimum 3/4 inch. Mist lubricator or similar should NOT be used. In hot enviornments (above 25°C) a cooler is recommended to increase life span of the LED panels. Air dryer is not essential, but recomended.

Power supply:
Standard 220V – 10 A power supply.

The inversion of the liner requires between 0,2 to 0,4 bar

During the installation, a preassure of around 0,4 bars is used.

Yes. This can be performed by closing the end of the liner and cutting that of after curing, or by using a transparent calibration hose or a glue-end (closed piece of calibration hose glued to the end of the liner).Calibration hose or glue-end is recommended.

Yes. Due to the constrution of the liner and chemistry, there will not be excess amounts of chemistry risking to flow into connecting pipes. The chemistry is not affected when coming in contact to water, making installation without preliner risk-free.

Yes. The chemistry is not affected by contact to water, making it possible to install the liner without preliner, even in pressing groundwater.

100 – 250mm

Due to the design and construction of the pushrod and light head, the system can be used through multiple 90 degrees, even in a 100mm pipe.

The pushrod on the system is 70m. If you are using two units simultaneously, you can double the length by curing the liner from both sides. .

Yes. Our liner can expand with up to 50%. This makes it possible to go from a 100mm up to 150mm (or 150 to 225mm) in one single shot.
