Scraper runways in new and existing plants

Scraper runways in sewage treatment plants are concrete components subject to heavy mechanical and chemical stress. Without suitable protection, even properly applied ready-mixed concrete cannot withstand such stress in the long run. Damage, such as flaking, cracking and loss of material, often occurs already a few years after plant commissioning. Until the nineties plastic material coatings were preferably applied both as protective measure and for scraper track restoration. Different coefficients of thermal expansion and the water tightness of plastic materials, however, have frequently been the reason for limited service life.

For more than 25 years our basin crest covers have proved themselves to be an economic solution for various types of tanks, and can also take the heavy strain from the scraper. Benefit from our experience!
