UKSTT offers a Trenchless Enquiry Service to assist people in all area's of trenchless technology. In the US, The National Association of Sewer Service Companies (NASSCO) was established in 1976 and is the oldest such association with a trenchless focus. The North American Society for Trenchless Technology (NASTT) was established in 1990.
Directional boring machine. Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig.
In the construction industry, moling is a trenchless method used to lay pipes. During the moling process, a pneumatically-driven machine known as a mole forces its way through the soil along the desired path of the pipe. Moling avoids the need to dig a trench and can be used to lay water pipes and the heating coils of heat pump systems. [1]
The purpose of the drill is to create a tunnel under surface obstructions. First, the operator surveys the area and the obstacle (road, sidewalk, driveway). Utility locators must supervise any underground work, and the path most clear of utilities is chosen to send the tool through. The first hole is dug on one side of the obstacle.
In 1988, Michels became a pioneer in trenchless construction by mastering the new technology of horizontal directional drilling. To this day, Michels is an award-winner and record-holder in many techniques used for the trenchless installation and rehabilitation of utility lines. [2]
TT Technologies is a construction equipment manufacturer producing microtunneling and trenchless products. [1]TTT was founded in 1991, and is based in Aurora, Illinois. [2]The company received an innovative product award from the North American Society for Trenchless Technology (NASTT) in December 2015 for a mini directional drill called the Grundopit K-keyhole.

Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...
