As application, we are providing postensioning for any structure as bridges, buildings, tanks of liquefied gas LNG, silos, covertures, communication towers, nuclear power stations, suspended structures, etc. in either internal or external post-tensioning.
The services provided by MK4 include the following aspects:
MK4 also offers complete packages including alternative design of the slabs in addition to the conventional incorporation of our MK4 tendons (supply, installation and stressing).
The advantages of PT in buildings can be summarized as follows:
Repair, maintenance and surveillance of structures, especially old building and monuments are additional activities in which we are presently becoming very active.
MK4 technical expertise and long experience in similar projects will assist you and support you in any phase of the project.
Regarding LNG projects, MK4 system owns ETA approval for cryogenic and LNG tanks and has also carried out several specific test under cryogenic conditions in independent laboratories complying with the most stringent international standards. Vertical tendons and horizontal tendons are normally used.
The use of precast or in-situ post-tensioned concrete instead of steel is becoming more and more common in windfarms.
This is mainly because it offers very important advantages: higher energy production thanks to higher pylons, lower transportation costs, construction flexibility, smaller maintenance costs.
Our Wind Post-Tensioned concrete Towers have been specifically certified by DNV/GLL for one of our wind farms in Brazil. Towers were almost 120 m height.
