About A-LOK

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. The key to protecting public health and safety, as well as the local environment, is a watertight system that includes the connection between pipeline and structure. In order to address this need, the original A-LOK connector design was conceived. From this original connector evolved A-LOK Products, Incorporated, a company created in order to meet the widespread demand for such patented innovations in watertight technology.

Recognizing that supplying customers with a quality product was a means to success, A-LOK set forth with a single commitment; to develop ecologically-responsive wastewater products that are solutions for both our customers and the industry. For over 50-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.

As we move forward, A-LOK recognizes the need and accepts the challenge to expand our original scope by creating watertight storm water systems in a similar manner as was done in the 1970s with wastewater systems. We, as a team, understand that by doing so we will contribute to preserving the environment and improving our infrastructure for future generations. With the support of talented human resources and a commitment to innovative design, superior craftsmanship, and outstanding customer service, today the name A-LOK remains synonymous with watertight quality in underground structures throughout the industry.
