A series of coal silos required structural enhancement & repair to withstand internal fluctuating loads.
A key aspect of the client’s requirements was for a repair system that was both structural, and fire rated.
NAFUFILL KM250 was selected as it has attained a structural R4 classification and meets with the F120 (120 mins) tunnel fire test.
Additional surface protect from carbonation and pollutants was provided by use of the MC COLOR System leaving an aesthetically pleasing finish.
