About Compaktuna®



The company Polytechnisch Bedrijf (P.T.B. ®) was founded in 1957 in Merelbeke, and it was one of the first manufacturers in Belgium of building specialities for the construction and general industry.


During the first years, it became renowned for its product COMPAKTUNA, still the No. 1 in Belgium in its category of products.


In the meantime, the product assortment has been expanded to include some eighty items amongst which COMPAKTUNA® remains one of the standard bearers. Later - in 1966 - a start was made with the manufacturing of cement-based products. In 1974, P.T.B.® built a new plant at the cloverleaf in Zwijnaarde. At this excellent geographical location, P.T.B.® expanded into a very modern dynamic enterprise consisting of the following departments: laboratories for research & development and quality control, production, stock, administration and sales. The present enterprise occupies an area measuring ± 30.000 m².


The range of products was further expanded through own developments, and today it comprises a complete offering of additives for mortar and concrete, primers, glues, mortars, plasters and finishing products.




There is also a steady increase in cooperation with partners, aimed at further strengthening the range of products and at offering innovative solutions to customers. The cooperation since 2005 with TECHNISEAL®, world leader in the development and commercialization of POLYMER JOINTING PRODUCTS must be mentioned here. Since the beginning of 2010, also the CORNERTAPE® range of products is exclusively distributed in the BENELUX.


All these different specialities for the building industry are distributed through the construction material commerce and the high-range do-it-yourself shops in the Benelux.


In the rest of the world, our products are distributed through agencies. We offer our partners our know-how as added value.


Besides producing and distributing materials for the building industry, P.T.B. ® is also active in the field of industrial floors, where it is solely responsible for the manufacture and installation.


As a fully independent family enterprise, P.T.B. ® is well-known for its high-quality specialties for the building industry and its excellent service. P.T.B.® is ISO 9001 certified.


P.T.B.® is a member of the Federation of Manufacturers of Construction Materials FEPROMA.
