Micro Piles

Micro piles, also known as mini piles, pin piles, needle piles, and root piles, are used in a variety of applications to resist compressive, uplift, and lateral loads. They have a diameter ranging from 3 to 10 inches and are load tested according to ASTM standards. Capacities can exceed 500 tons.

Micro-Piles

Micropiles are also known as minipiles, pin piles, needle piles, and root piles. The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically an all-thread bar is used. The finished micropile resists compressive, uplift/tension, and lateral loads and is typically load tested in accordance with ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable micropile compressive capacities of more than 500 tons have been achieved.

Self Drilling Hollow Bars

The hollow core bar system consists of three main components: the head, the steel tendon, and a single-use drill bit. The steel tendon is a hollow core bar with continuous cold rolled threads throughout the bar's length. The continuous threads are beneficial in that they allow the bar to be cut at any desired length, or joined with our exclusive coupling system to achieve your desired drill depth.

Designed to increase production, the hollow bar system can be simultaneously drilled and grouted into loose or collapsing soils without the need for a temporary casing. In order to ensure smooth installation, we supply a large selection of drill bits, allowing our customers to install the hollow core bars in a variety of different soil conditions with most standard drill rig configurations.

Due to the wide range of cross-sections and bar diameters available, we can design a system for you to carry almost any required load.
