Método de aplicación:

Application was carried out in accordance with Belzona Know-How System Leaflet TCC-15.


Hechos Belzona:

After the original insert box was removed the large hole that had been made by the acid eating though the concrete, leaving only remnants of the reinforcing bar was discovered. With the use of heaters, the hole was repaired and sump protected with Belzona within the allowed three-day time frame. Still performing as expected – problem totally solved.
