Micropile Underpinning Bracket
Now you can install a pre-engineered foundation repair bracket for your next micropile project that multiplies your safety potentials. Developed as a joint venture between leaders in their respective fields, Earth Contact Products and TEI Rock Drills have put their expertise together to design a system to make the installation of micropile brackets as efficient as other underpinning systems. Together we have adapted a proven ECP-style underpinning bracket to attach to the TEI Hollow Bar Drilling Rig. How does this work? The new ECP micropier brackets eccentrically transfers the load of the structure to the hollow bar grout column, while maintaining the ability of a continuous manifold lift. This key element in the design allows for engineers and contractors the convenience of a proven, off-the-shelf bracket system that can easily adapt to micropile applications. This type of underpinning system can be used on residential and commercial jobs alike. No longer are you restrained from using a underpinning system due to cobbles or other obstructions in the soil.
Introducing our Micropier Bracket System
The Earth Contact Products MP-350 Micropier Bracket System is easily installed into difficult soil conditions that can contain large cobbles, obstructions and layers of rock. The TEI/MP-250 Drill Rig that is used in conjunction with the ECP micro pier bracket system is a lightweight and portable drilling unit and used worldwide in the pier installation industry. With its proven track record, you’ll find that the installation and drilling of the micropile is fast and efficient. With its grouted column, lateral loading in suspect soils is no longer a problem. The micropile works on skin friction to achieve maximum capacity. Also, the ability to achieve capacity through end bearing the pile into a socket in the bedrock makes the ECP micropier a great application in many job site conditions. The micropiers are an engineering feat in themselves. The hollow bar micro pier installs simultaneously as the core hole is being drilled, the grout is pumped thru the hollow bar, filling the shaft and displacing the cuttings–ALL in a simultaneous operation! Thus, saving time and labor costs.
With this addition to the ECP product line, Earth Contact Products is offering contractors and engineers the ability to add value to their businesses by opening up new business opportunities when other underpinning systems may not be able to be installed. Instead of bearing on shallow layers of bearing strata you now can be assured that your underpinning system has gone below these weak layers to support structures.
