Your single point of reference for all your Geotechnical Inquiries


Lightweight and flexible, our SMART MPBX (Multi-Point Borehole eXtensometer) has six anchor points and an integrated electronic readout head. The small instrument diameter means that the head can be recessed in a 50 mm (2 inch) borehole – no need for oversize holes or reamed collars. It also allows multiple MPBX’s to be installed in the same long borehole. Each instrument is custom manufactured to the length you require, and allowing you to place the anchor locations where you need. They arrive on site ready to install. Just place in a borehole and grout. No assembly required.  Our biggest selling item, the SMART MPBX is in use around the world.
