Materials for Use with the Tenbusch Insetion Method (TIM™)


The TIM™ System installs rigid pipe. The TIM™ installation process requires both a strong and rigid replacement pipe and does not work with flexible or weak materials.

Pipe bursting was originally developed to pull a flexible pipe through the existing pipe. High density polyethylene and PVC pipe have been used extensively.

Concerns with the design life of the materials used in all facets of infrastructure have caused new methods and materials to be developed. In the case of existing sewer and water pipe the new materials turn out to be the old standby's - clay and ductile iron.

The Tenbusch Insertion Method (TIM™) is the only method that allows these new configurations of the old standby materials to be pushed into place. This patented method expands the old pipe and allows for upsizing - sometimes and in some soils - very dramatically.

The result is that your city's infrastructure can be replaced with new pipe that has a design life of more than a mere 50 years.

Rigid Pipe Products Available for TIM™


Ductile Iron

American Ductile Iron Pipe Company (ACIPCO)

By its nature, ductile iron pipe possesses substantial columnar strength, which makes it a superior material for trenchless applications. AMERICAN Ductile Iron Pipe offers three joints designed specifically for use in direct jacking, trenchless pipeline replacement, and microtunneling installation.

Steel and Stainless Steel Pipe

Permalok Corporation

PERMALOK® is a new steel pipe product designed to eliminate field welded connections. This mechanical press-fit connection is flush with the inside and outside surfaces of the pipe and is capable of withstanding significant internal or external pressures. PERMALOK® steel pipe is currently being used in pipe jacking applications.

The invention of PERMALOK® The Interlocking Pipe Joining System, provides a dramatic advancement to the quality of tubular steel construction by providing a pre-installed precision joint connection which is quickly, easily and permanently mated during field construction. PERMALOK® practically eliminates the need for in-field welding and the down time associated with it.
