What are the differences between using silo batched or pre-mixed mortars compared with site batching and mixing?
For consistency and convenience silo based and pre-mixed factory produced “tub” mixes are usually preferred. Silo based mixes can then be adjusted on site to suit the suction requirements of the bricks.
Site batching and mixing on site is suitable for smaller projects but can cause variations in consistency, especially when coloured mixes are required.
Important: It is essential that the correct strength specification of mortar is used as mortars which are too strong can potentially lead to cracking.
