KOSTER Sewer and Shaft Mortar

Resistance to mechanical and chemical stresses often plays an important role in sewage pipes and shafts. Surface protection must be able to withstand high and low pH values, as well as abrasive wear, in order to ensure a long service life. For this purpose, KOSTER Sewer and Shaft Mortar was developed. After thorough surface preparation has led to a stable substrate and efflorescence has been removed, KOSTER Polysil TG 500 can be applied as a primer. Afterwards, KOSTER Sewer and Shaft Mortar is applied in a layer thickness of 1/8 to 1-1/8-in. KOSTER Sewer and Shaft Mortar is fiber reinforced and develops a high compressive strength, as well as excellent chemical resistance. It can be applied below the water line even under flowing water.
