Sauereisen’s SewerSeal F-170 is a durable, calcium aluminate-filled sealant. It prevents water infiltration into municipal collection systems. Ultimately, this reduces the amount of sewage to treat and total treatment expense. SewerSeal’s versatility allows for use in manholes and lift stations regardless the substrate - concrete, brick or steel. F-170 may be spincast from ground level. This minimizes downtime and improves safety by preventing confined space entry.
