An expansion joint is gap left in brick or block work. This joint is left to allows walls to move. Over time, building materials as well as the floor contract, expand and move. A flexible joint is required to prevent cracking. If mortar was placed at these key points, it would crack.
For outdoor caulking, we use specialist sealants that have UV protection and a stronger compound that prevents them from breaking down in harsh weather conditions. Our caulking professionals will guide you on the best products needed for your job. We have a large range of colours to match the colour of your bricks, block and pavers.
Control joints are another area that needs to be caulked. They are put into place to control were concrete could potentially break or crack. They are common in slabs. They help prevent large cracks in spots you wouldn’t want them, and also allow the sections of the slab some room to move. Our professional caulkers will visit your location in Sydney and will advise the best product for your concrete and the most accurate colour should your drive way be finished in a colour.
