Pieresearch’s UNIBAR® Receives New Patent for Revolutionary Adjustable Centering Device

Pieresearch®, a leader in the design and manufacturing of alignment and centralizing devices for the geo-construction industry, has received a new patent for its revolutionary Adjustable UNIBAR® Centralizer (patent number 10,584,459).

The answer to uniform reinforcement steel spacing requirements for single-bar foundation and earth support elements is provided by Pieresearch’s Adjustable Quick-Lock® UNIBAR® Centralizer. These rugged, light weight, quick and easy-to-install, non-corrosive centralizers are designed to keep the bar or tendon centered in the borehole to allow for required concrete or grout cover. Proper alignment in concrete or grout placement is a critical element in quality assurance and quality control.

The adjustable UNIBAR is ideally suitable for use with soil nails, micropiles, tiebacks, or augercast-in-place piles. The UNIBAR accommodates single and multi-bar anchors both threaded and non-threaded, strand anchors, encapsulated (DCP) anchors, and other types of soil and rock anchors. The snap-together centralizer can be attached with zip ties or tie wire for any type of reinforcing multiple diameters. They are equally effective for steel or pipe applications.
