Techno Metal Post and non-concrete foundations

Helical steel piers have become the number one solution, proposed by Techno Metal Post, when dealing with problem foundations.  Poor soil quality and ground movement can disrupt the stability of buildings, and this method of solidifying them fixes that situation.

Clément Rouchouse and Maxime Albafouille started a new business adventure, in the Rhône and Isere area within France, back in 2012.  They invested in the equipment, and began installing this specialized system, with determination. "We often get called in urgent situations, where the soil quality is not suitable to lay traditional foundations.  We work in the housing industry, but find ourselves expanding to tackle larger infrastructures.  From a traditional concrete foundation on unstable ground, to a slab cast directly onto the piers, or a wood/steel structure built atop them, Techno Metal Post’s approach suits all types of construction", says Clément Rouchouse.

From the technical standpoint, the piers are screwed into the ground until it reaches compact soil.  At the time of installation, the machines measure the torque, which determines the load bearing capacity in real time.  Steel supports are then fixed onto Techno Metal Posts’ foundation piers that support the structure.  Whether the foundation gradually settles or raises the structure (depending on ground movement), the weight is permanently transferred onto the piers.

Thanks to the dedicated and experienced engineering services, Techno Metal Post has developed a range of hydraulic machines, specialized in the installation of helical piers.  The compact and versatile equipment can access different terrain, and allows the installed piles to hold a bearing capacity of 50,625 lbs (225 kg).

"Without excavation, without laborious concrete pouring (whether permanent or temporary), this system also has a very low environmental impact. We are independent but part of the TMP network, which provides us with engineering services that are responsible for analyzing and validating all projects," adds Clément Rouchouse.  At the present time, this revolutionary system that comes from Canada, has been running for over 20 years worldwide and has a network of over 120 dealers.  Techno Metal Post is certified by the CSTB, and intends to establish a solid presence in the French region of Rhône-Alpes.
