In order to counter the displacements and deformations of structures, the innovative MICROANCHORS solution stabilizes and anchors the structures against the ground to stop the thrust of the ground located behind.
Quick and minimally invasive, this process uses a series of active micro-anchors arranged in a precise mesh on the structure to be treated, which are associated with the exclusive URETEK® expansive resin.
The micro-anchors are made up of several metallic elements in galvanized or stainless steel. Added to this are the impermeable properties of the specific URETEK® resin, which protects all against corrosion over the long term.
After analysis and definition of the mesh for the installation of the micro-anchors, the structure to be anchored is perforated by means of electric manual perforators fitted with special small-diameter tips.
Subsequently, the micro-anchor is installed in the hole thus created up to the planned length, manually or using electric hammers if necessary.
The next step is to create a strong seal area by injecting the expanding resin through a gun connected to the end part of the steel tube of the micro-anchor. This expands quickly by compacting the soil before solidifying in just a few seconds. This operation allows immediate tensioning of the micro-anchor thanks to an adjustable mechanical system controlled by a specially calibrated tester-controller.
Thus the MICROANCHORS is effective from the end of our intervention and in a lasting way on the treated structure.
