Epoxy mortar for repairing of concrete

The special advantage provided by this mortar is:


Epoxy patching over concrete
a. High strength

b. High abrasion resistance

c. Water resistance

d. Having facility to apply in thin film of few millimeters.


Now we will learn in which locations/conditions this mortar is essential. They are

1. Where concrete bonded with epoxy can not be used due to accessibility problem.


2. Where repair work required less than 40 mm thick overlay of repair mortar.


3. Where a small quantity (No.) of point or small area have to be repaired. This is practical for less than 0.1 Sqm.


We have mentioned earlier that this mortar is applicable when patch thickness is less than 40 mm. But when the required thickness exceed 15 mm and patching work have to cover large areas then patching work done in layers providing mesh reinforcement fixed with the help of U-nails or sometimes by shear keys.
