If you are looking into concrete Crack Repair in Natick MA, you want to have as much information as possible about what the process entails. There are a number of different methods that are used to fix cracks. Whether or not the crack repair will be permanent, or how long the repair will last is naturally dependent on the kind of method used in each case. Some crack repairs are of a higher quality than others, which is why it is a good idea to have all this information handy before seeking crack repair services.
One common method of crack repair is hydraulic cement crack fillings. In this instance, a groove will be chiseled into the wall, usually in the shape of an inverted V. Hydraulic cement is then used to fill the groove, which in turn plugs the hole once the cement becomes rigid. It is a longer term solution than the caulk crack repair option, but this is to be taken with a grain of salt. The bonding between the hydraulic cement and the wall is not particularly strong. As moisture levels and temperatures change, the walls begin to move and will loosen the plug over time. This remedy usually lasts for about two years.
Epoxy crack injections are another popular option for fixing cracks. This works very much like the hydraulic cement option. In this case, epoxy is poured into the crack. Because it takes a long time to cure, it will be able to reach the other side of the crack. Once it hardens, epoxy will effectively keep water out. The problem however is that new cracks can form over time as the temperature and moisture levels fluctuates making the wall move.
The best solution is usually polyurethane polymer sealing. This is a high viscosity product with properties that allow it to expand and hold the concrete effectively, thus repairing the crack effectively. Polyurethane polymer sealing is a standard method used by Crack Repair in Natick MA companies such as Drycrete Waterproofing among others. DIY crack repair is never advisable since you may not have the right skills or knowledge to perform the same type of quality repairs that a professional would be able to offer you.
