The Beginning of Watertight Tests


PROJECT LOCATION:

United States, Hartford City, Indiana
United States, Spring City, Pennsylvania

Date:

1970-1971

PRECASTER:

Hartford Concrete Products / A.C. Miller Concrete Products

THE SITUATION:

As part of developing standards for communication infrastructure in the United States, Bell Laboratories develped new test standards for the precast concrete industry.  Bell Laboratories - in conjunction with A.C. Miller Concrete Products, Hartford Concrete Products, and Concrete Sealants - started testing utility vaults for watertight integrity. Utilizing a water test and a smoke test, it was proven that butyl rubber sealants provide the best, watertight seal.

THE SOLUTION:

Many technological advancements developed from these new standards and test methods.  One of those advancements is CS-202, a sealant that provides superior adhesion and watertight protection between concrete castings than previously available technologies.

Sealant Application:

  • Utility Vaults

ConSeal Products Used:

Applicable Industry Standards:

  • ASTM C-990
