Concrete has many benefits, but the most significant one is its durability, as well as the fact that it is easier to maintain than other construction materials. However, there are specific issues you will encounter in time, especially if you’re not maintaining it properly. Some of the concrete problems will include discolouration, scaling, shrinkage, cracking, other issues.
Here are some troubleshooting tips for many of these issues:
You can reduce cracking on your concrete surface if you remove the soft spots in the subgrade, organic material, and topsoil. You can also compact loose soil or install concrete joints through forming, tooling, and sawing a groove.
Another important thing to do to reduce cracking is to maximise the amount of course aggregate and avoid using retardant admixture because this can easily weaken your concrete so that it becomes prone to cracking.
To remedy discolouration, you need to prepare a uniform subgrade and wait until the water evaporates before finishing the process. This will prevent hard trowelling on the surface and ensure the colour is even throughout the concrete.
It is essential to talk to your contractor and ensure that they are correctly bonding materials when applying thin topping mixes. They must also use the right amount of steel reinforcement on each concrete slab. Also, concrete must be placed on an absorptive sub-grade to ensure that water will not be pushed on the top of the slab.
Overall, choosing the right concrete for your intended application, maintaining it regularly and repairing it when issues arise, will ensure that you can enjoy your concrete surface for years to come.
