Normal concrete structures and normal floorings will not withstand the acids and will give way very shortly disturbing the trolley movement and also aesthetically looking ugly. There will be heavy load movements in the factories using trolleys and pork lifts. Normal floors cannot withstand the load and the movement of wheels will damage the flooring. A special type of flooring is required to overcome these problems. There are different methods followed in acid alkali resistant lining like conventional tiling using 38mm thick acid resistant bricks, epoxy coatings and the latest with vitrified unglazed tiles which are non slippery, stain free and non-porus. For filling up of joints also, we now have colored epoxy grouts, which serve the purpose and also aesthetically look good.
