Flexible high-quality liners help you line any pipe. Boldan offers liners in numerous sizes, from 30 mm to 500 mm in diameter. Our flexible liners mean you can even line pipes that have change in diameter in the section being lined. Our selection also includes unique two-sizes flesible liners.
BRAWOLINER®
BRAWOLINER® is a seamless textile liner with a flexible construction. This makes the liner a perfect solution for renovationg even the smallest pipes. BRAWOLINER® has a foil coating and can adapt even 90° angles and changes in the pipe diameter. The inside of the liner is smooth without any wrinkles or folds.
The liner can be installed with low pressure of 0,2 bar, which protects the pipes from further stress.
The advantages of BRAWOLINER®:
Able to cope with multiple bends of up to 90°
Handles one pipe diameter change
Simple installation with low pressure
Suitable for most renovations
DN 50–250
Lengths 25 m, 50 m or 100 m
BRAWOLINER® 3D
BRAWOLINER® 3D is developed for renovating of pipes with variable diameters. The liner can handle even large diameter changes without folds or wrinkles. It is also suitable for pipes with more than one diameter change.
The advantages of BRAWOLINER® 3D:
Large diameter changes
Can handle two diameter changes in a pipe
DN 70–100, DN 100–150 and DN 150–200
Lengths 25 m, 50 m or 100 m
BRAWOLINER® XT
BRAWOLINER® XT has a stiffer construction, making it suitable for renovation of broken or deep pipes with bends and changes in diameter. In spite of the higher stiffness the liner is flexible and easy to handle
The advantages of BRAWOLINER® XT:
Stiff construction for renovating of broken pipes
Suitable for deep pipes
DN 125–250
Lengths 25 m, 50 m or 100 m

Calibration Hoses are used in open-end installations to squeeze the liner to the wall of the pipe. Also used in the manufacture of glued open-end liner and to prevent excessive swelling of the liner in free space. In Boldan's range you will find the Calibration Hoses in sizes D50 - D400. Calibration Hoses are also available in flexible and heat resistant versions.
Preliner is installed between old pipe and the liner in order to protect liner and resins for example from dampness and sharp edges. Preliner avoids spreading of the dissolved resin and other substances from the liner to the area surrounding the pipe. In case the pipe under renovation has been badly damaged, preliner can also be used as formwork for the liner. Preliner is also used in the free space (between the inversion drum and the drainage point) to prevent excessive swelling of the liner. It is recommended that Preliner is always used in the concrete pipes to prevent any damage caused by the water outside the pipe.
We manufacture high-quality T-liners that fit all branch-off pipes. Thanks to 3D cutting, our T-liners always sit tightly and ensure the water-tightness of the branching. With flexible T-liners, even the most challenging branches are easily and quickly lined. Our selections includes T-liners for all sizes of pipes and degrees of angels. We also manufacture products according to our customer's specifications.
Using the silicone installation tools of T-liners manufactured by Boldan, one ensures smooth and effortless installation of T-liners.
Bladders are 3D cut and the joints are sewn and glued to ensure resistant final result – service life of our bladders is remarkably longer than that of other available bladders.
We produce also custom size bladders based on special orders.
The installation tools for T-liners we manufacture are of the highest quality available on the market and when used right, they can be used in multiple different installation projects. These hand-made silicon tools are also suitable for steam hardening.

Bladder body to be placed into the bladder is made from flexible material enabling smooth installation of the T-liner through bends.
Bladder bodies to be placed into the bladder are of different thicknesses (8, 10, 12, and 16 mm) for different use.
Diameters of the bladder body ends are 30, 40, 60, and 90 mm and these can be equipped with steam couplings.
Linerdrain is applicable for renovation of most common cast iron floor drains, without damaging the structures. The drain for renovation is a patented and completely Finnish product meeting the type approval requirements established for floor drains by the Ministry of the Environment. VTT has performed flow measurements of the floor drain according to standard SFS-EN 1253-2.
Flexirohr is a three layer polyethylene pipe specially designed for renovation of gravity sewers. After installing Flexirohr the capacity of the sewer remains normally the same. This is due to the better flowing properties of smooth plastic compared to concrete or cast iron pipes. Furthermore the self cleaning of the sewer enhances.
Flexirohr pipe is developed by Renos. The structure of the pipe allows bending the pipe through manholes without any loss of stiffness. The pipes are delivered in 50 meter coils or 6 meter lengths. The 6 meter long pipes are welded together with a PEX-welding ring. The welding can be performed to desired lengths in the worksite. The welded, continuous pipe is pulled in to the host pipe with a winch and a wire. The sewer can be functional during the procedure.
The advantages of Flexirohr method:
Dimensions:
DN 90 - 50 meter coil
DN 118 – 50 meter coil
DN 175 – 6 meter lenght
DN 200 – 6 meter lenght
DN 235 – 6 meter lenght
DN 270 – 6 meter lenght
