We do our crack repair with the Dulux Avista Crack Repair epoxy mixed with dry silica sand.<\/p>\n\n\n\n

We start with enlarging the cracks with a diamond blade and often will add stitches perpendicular to the crack in which we add Baton screws to create structure.<\/p>\n\n\n\n

After respecting the cure time of the epoxy, we grind the top off to make it look seamless and it enables us t resurface over it without seeing the crack anymore. It also prevents moisture leeching up and damaging\/reactivating the resurfacing compound. This is the primary purpose of the crack repair.<\/p>\n\n\n\n

We often go to the extent to add sawcuts to enable the slabs to move and crack in those weak spots without affecting the coating<\/p>\n\n\n\n

Many people ask questions about crack repairs and their longevity, purpose, drawbacks. Here is a Q&A with the most common questions:<\/p>\n\n\n\n

1 “Do you warranty the crack repair?”
In short: No. While we do our best to remedy to an existing crack, in no way are we able to avoid the substrate moving and the concrete cracking again. Would you blame a renderer if the wall cracked?<\/p>\n\n\n\n

2 “My concrete is settled and the cracks have already appeared, can it move again?”
Years of exposure to elements like ran, heat and vehicles driving on it will slowly deteriorate your concrete as explained here<\/a>. It is not rare to see cracks appearing on brand new slabs as well as old slabs during the hot summer days.<\/p>\n\n\n\n

3 “What can you do if the concrete cracks over a concrete crack?”
Well, not a lot. The resurfacing compound we use is of a cementitious base and will harden to 45 MPA (Which is harder than most concrete driveways with 32 MPA). It doesn’t have much bend to it and will crack with your slab rather than start lifting. We can repair the crack again and attempt a patch work but will have to warn you about the potential slight difference of colour.<\/p>\n\n\n\n

4″What can I do to avoid my concrete to deteriorate and crack?”
Ensure that adequate expansion joints and cuts are placed when your concrete is poured. Ensure adequate drainage around your concrete, and seal your concrete regularly (every 18 to 24 months).<\/p>\n\n\n\n
