Although concrete is considered to be one of the most durable construction materials in the world, it does not mean that it is already invulnerable to damages such as cracks. Cracks may appear on the concrete due to various factors. In most cases, cracks occur because of natural reasons. Natural calamities, such as earthquakes and floods, largely contribute to most concrete damages. Most concrete floors and walls can only handle a certain amount of pressure and any level higher will result to cracking.
Using injection grout to fill cracks is an effective way in providing waterproof and corrosion protection on the structure of any concrete work. Injection grouts are available on the market. You can choose from a wide variety of properties, characteristics, and uses. Normally, injection grouts have high bond strength and high stability at strong temperatures. Although there are many types of grouts to choose from, you will need only one or two types depending on the concrete and severity of the concrete cracks. A certain injection grout may be useful for one purpose but inappropriate for another.
Polyurethane resins can be used for a range of different applications. Their properties can vary markedly in terms of their liquid or hardened phases, viscosity, thixotropy, foaming reaction (in the case of hydrophilic resins), and mechanical strength. In general, they have a notably low viscosity, cure rapidly and are flexible. Polyurethane resins are also selected for their ability to seal against water inflows.

Cracking is very common on concrete driveways and footpaths. This is due to the insufficiency of load capacity that a concrete could handle in a daily basis. Public roads that are made of concrete are expected to be used everyday so it is just understandable to see cracks in some areas. Nonetheless, they should be treated as soon as possible to avoid uncontrollable scenarios.
Concrete crack repair that worked!
The quality of concrete over the past decade has deteriorated resulting additional unwanted cracking in concrete driveways and footpaths. We got tired of grinding off our decorative concrete displays because of the unwanted cracking. After we moved in to our new premises there has been additional ground vibrations from the civil works being done on the train line behind us plus trucks doing deliveries each day our displays kept on cracking.

How to repair cracked concrete
To repair cracks in a concrete floor, first ensure that the area is free from dust, grease and surface contaminants. Concrete fix can be applied to both dry and damp surfaces, but standing water in any voids, pits or pores should be removed prior to application. While wearing safety glasses and chemical resistant gloves, pre-mix both parts separately, then mix equal parts of each together in a suitable container. Mix thoroughly for three minutes with an electric drill and paddle mixer. Check out http://www.handyman.net.au/how-to-repair-cracked-concrete to know more about the topic.

Crack-Pac® Injection Epoxy
High strength, rigid crack repair
The Crack-Pac® two-part, high solids, low-viscosity crack injection epoxy is designed to repair cracks in concrete. The mixed adhesive has the viscosity of a light oil and a low surface tension that enables it to penetrate fine to medium width cracks. Resin is contained in the cartridge and hardener is contained in the nozzle. Once the nozzle is threaded onto the cartridge, the hardener is released into the resin-filled cartridge by turning the knob at the base of the nozzle. The two components are mixed by shaking the cartridge.
