TT Technologies offers a full line of Grundoram pneumatic pipe ramming tools for trenchless casing installation. Available in 11 styles, Grundoram ramming gear is able to accommodate 4- through 120-inch casing installations. These tools provide accurate installation in a variety of soil conditions, including rockier soils.
During the ramming process the rammer is attached to the rear of the casing, and then drives the pipe through the ground with repeated percussive blows. Ramming tools, in general, are capable of installing 4- through 147-inch diameter pipe and steel casings.
Ramming has proven effective for horizontal, vertical and angled applications. The process provides accurate installation of casing in a wide range of soil without surface slump, making it ideal for installations under railways and roads. (800) 533-2078, tttechnologies.com
