Sanitary & Storm UV Liners

BKP Berolina specialises in glassreinforced, UV-cured CIPP liners for trenchless sewer and stormwater rehabilitation. Its Berolina-Liner range combines structural strength with thin wall construction, helping restore pipe integrity while preserving internal diameter. Factory-impregnated and supplied ready for installation, the liners accommodate a range of pipe sizes and profiles. Efficient UV curing supports rapid rehabilitation with minimal excavation, reducing disruption and extending the service life of existing infrastructure.

Applications

Gravity storm and sewer pipes
Round and ovoid pipes

Features & Benefits

Faster installation compared with conventional methods.
Reduced disruption to the end user and surrounding operations.
Easier installation in difficult or restricted-access locations.
Extends the service life of existing assets and infrastructure.
Supports a more sustainable approach to asset management.

BKP Berolina-HF-Liner

UV GRP, High-Strength Liner For Gravity Sewer Applications

Due to the special construction of the glass sheets and higher glass content, Berolina-HF Liner achieves higher mechanical characteristics resulting in a reduction of the structurally required wall thickness compared with BKP’s standard UV GRP liner. Berolina-HF Liner is also available with Integrated Enhanced Security (IES), which can reduce installation time by up to 60 minutes.

Areas of Application

Circular profiles: ID 6 – 63”
Ovoid cross-sections: 14 | 21” – 48 | 71”

Features & Benefits

Higher mechanical characteristics compared to the Berolina-Liner
Reduction of the structurally required wall thickness compared to the Berolina-Liner
Seamless design, particular extensibility
Up to 1,640 / 3,280 ft | ≤ 12″
Can be stored up to 6 months (VE liners) or 12 months (UP liners)
Fast curing and smooth surface
Suitable for all standard pipe profiles
Quality management in accordance with EN ISO 9001:2015
