A-Lok Products, Inc.

A-LOK set forth with a single commitment; To manufacture and develop ecological-responsive wastewater products that are solutions for both our customers and the industry. In the last 45 years, ever-changing demands in the sanitary sewer industry have led A-LOK to develop and offer a wide range of new products. These include flexible pipe-to-manhole connectors for all applications, plastic inserts and seals for manhole entries and joints, forming for manhole inverts, corrosion resistant linings, lubricants and sealants. With the advent of the Clean Water Act in the early 1970s, the primary concern of the wastewater construction industry was watertightness. From that time to present day, precast concrete has been recognized as the construction material best able to provide strength and durability in underground structures.
