INDEX Técnicas Expansivas S. L.

INDEX Técnicas Expansivas says its THE direct-fix concrete anchor, under DIT plus no. 708p/26, has a two-step reuse check for temporary applications: thread-wear gauge assessment and visual inspection for deformation, corrosion or damage, for zinc-plated or ATLANTIS carbon-steel anchors in Ø8–Ø14.

INDEX Técnicas Expansivas has expanded its bimetal direct-fixation concrete anchor range with two versions: TXF with a female threaded head and TXD with a round head.

INDEX Técnicas Expansivas is hosting INDEX Academy webinars on 16 September (Spanish) and 30 September (English) comparing its TNUX and TN4S nylon anchors. The sessions cover base material, installation type, required fixing behaviour, and how the anchor works and knots after installation.

INDEX Técnicas Expansivas explains galvanic corrosion, which occurs when two different metals contact in the presence of an electrolyte such as moisture, causing one material to corrode faster and affecting joint durability.

INDEX outlines how to prevent leaks in rooftop photovoltaic installations, stressing that every roof penetration must support mechanical loads while preserving watertightness.

INDEX reports that its MTP-A4 anchors, made entirely of A4 stainless steel and ETA certified for C5-M corrosion conditions, are being used to rebolt deteriorated routes in Jamaica's Discovery Bay and Coral Springs.

INDEX has added the TFJ concrete screw with Torx drive to its direct-fixing range, citing improved torque transmission and reduced tool wear. The C1 zinc-coated steel screw is intended for indoor structural and non-structural uses, including near-edge and reduced-spacing installation.

INDEX reports that its MTH anchor has a new European Technical Assessment (ETA) covering improved mechanical resistance and wider installation options.

INDEX reports an updated European Technical Assessment (ETA) for its THE concrete screw, adding reduced embedment depths in M10, M12 and M16 for seismic C1 and larger depths in M16 for seismic C1 and C2 in cracked and non-cracked concrete.

INDEX publishes an educational guide on chemical anchors covering installation steps, resin types (hybrid, polyester, vinyl ester, epoxy), advantages over mechanical anchors, common errors, and substrate selection, referencing its MO-VH, MO-P+, MO-V and MOPURE ranges and an INDEX Academy course.
