AURORA, Ill. – Twenty-one models of Grundocrack pneumatic pipe bursting tools from, TT Technologies, are available to renovate water, sewer, gas, electrical and telephone systems from 4-inch through 54-inch diameter. Models include 15 rear expander high production tools and 6 straight-barrel auto-reverse special application tools.
The Grundocrack system effectively bursts failing pipe. A constant-tension Grundowinch guides the tool through the existing pipe. The tool’s percussive action breaks apart the “host pipe” and displaces fragments in the surrounding soil, while simultaneously pulling in new product pipe. Failing pipes can be replaced with same size or larger diameter product pipes.
