Nautec was engaged by Permaducto S.A. de C.V. to participate in the new structure installation of ELM 26.
The team used Nautec’s NaX® Q80-H high performance cementitious (HPC) grout to fix the platform to the seabed at 22.5 meters water depth by performing infill grouting between the pile and the sleeve of the structure.
ELM 26 is a 4-legged pile-sleeve platform with a total calculated annular volume of 14.5m3 (32 material tons). The project consumed 36 tons in total.
