The in_liner production facility is the largest manufacturing plant of the liners for the sewer networks renovation in Poland. It has been officially operational since June 2019, although production of the first in_liner took place as early as April 2018. It is located in Gdów (Małopolskie Voivodeship).

We fulfill orders for ECR fibreglass liners, with diameters ranging from DN150 to DN2000.

Our capacity is approximately 300 km of liners per year. Our products have already been installed in many Polish and European cities, including Bydgoszcz, Gliwice, Katowice, Rzeszów, Suwałki, Świecie, Włocławek, Zielona Góra, as well as Tallinn and Klaipėda.

The liners are manufactured in a 2600 m² hall equipped with a glass folding line, a soaking line for liners up to DN800 and a second soaking line for liners up to DN2000, 2 x 24 ton resin tanks, as well as many other components including the machinery.

Orders are normally processed within two weeks. There is a possibility of placing an express order – then the liners are manufactured within three days.

We take care of the customer at every stage of order processing, including the possibility of ordering the transport of products. During the winter period, transport is carried out in isotherms.
