I always get asked to repair cracks in concrete driveways, after all its what I do. Most cracks occur in concrete from movement underneath the slab. The crack occurs at the stress point in the slab. Concrete is so hard that it really has no flexibility to it so it has to give way by breaking.
The time comes to repair and should be done before old man winter makes it worse. Water can get into the crack, freeze and break the concrete away exposing more problems. The crack will need to be chased then bonded with repair material that is stronger than concrete. If the slab is still moving this can be a problem down the road as the concrete can break again. Slab jacking can help bring the slab level again and remove some of the stress so the repair can have better success. Once bonded the crack can then be filled with concrete.
Once you fix the crack and it is filled you still have an ugly crack. You can then coat with protective coating to hide all the repairs and make your driveway look new again!
Just finished another application of this great product called Streetbond.
This product is amazing! First of all it coats both concrete and asphalt and will not delaminate , shrink or crack. We can put this product down in an endless array of colours or even have a custom colour done. The colour will not fade even after years of being in the sunlight. This product will also stand up to years of punishment from our harsh Canadian winters.
We turned this drab old concrete driveway into something the client can be proud of again. We fixed all the holes, cracks and imperfections with new concrete then applied two coats of Streetbond. This job was finished with Irish Cream colour.
• Flexibility – Unlike most asphalt coatings, StreetBond coatings work with the normal expansion and contraction of asphalt surfaces and will not peel, delaminate or shrink-crack.
• Durability – StreetBond coatings are tough enough to withstand traffic wear, highly resistant to water damage and have superior adhesion characteristics that outperform other decorative asphalt coating products.
• Environmentally Responsible – StreetBond coatings help contribute to a healthy environment. They are nontoxic, fully recyclable and water-based. They have very low volatile organic content (VOC).
• Chemical Resistance – StreetBond coatings are resistant to damage and deterioration when exposed to fuel, engine oil and deicing agents.
• Color Stability – StreetBond coatings incorporate UV stable pigments that are fade-resistant when exposed to harsh sunlight.
• Friction – StreetBond coatings have excellent friction properties resulting in safe slip- and skid-resistant colored concrete surfaces that exceed all government regulated vehicle skid resistance requirements.
Many hockey and lacrosse games had been played on this old sports court. We where asked if we could fix it up a bit and give it new life. At first glance it was in real bad shape and had some bad spalling/cracking. We also had to remove the old the old epoxy coating as the polyaspartic would need a good bonding surface. The aggressive tooling on our machine was able to get down to the original concrete so that we have a good surface to bond to. We did have some crack and pitting repair as well that we had to get done first before the grinding. Prep is the key! See picture bellow.
We then had to apply several coats of white polyaspartic, add some lines then top with a layer of clear. The result is a nice looking hockey rink that is ready for big game.
