  • A•LOK Products Inc.

    In the early 1970's, the primary concern of the wastewater construction industry was watertightness. At that time, as it is now, precast concrete was recognized as the construction material best able to provide strength and durability in underground structures. The key however, to protecting public health and safety as well as the local environment was a watertight connection between pipeline and structure. In order to address this need, the original A•OK 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.

  • BEBO Arch Systems

    In the early 1960's, the Swiss engineer Dr. Werner Heierli began the development of overfilled concrete arch systems. The objective was to build concrete arches with a minimum thickness, sufficient to carry the applied loads, but also stender enough for the passive resistance of the backfill to be mobilised by means of elastic deformations of the arch. With this concept, the fill could contribute to the load carrying capacity of the arch and become part of the structure rather than just representing a loading. This phenomenon, known as the
