Concrete Repair Brazos Valley
Concrete repair, unfortunately, is needed, and there is not much to prevent concrete from never being repaired. Mainly because concrete is directly proportional to the soil it lays in. Over time the concrete will start to settle and become weaker. In some cases, however, the concrete can be raised by mudjacking or patching.
Concrete Raising Methods
The most popular of the repair methods would be mudjacking. There are many reasons why mudjacking is a popular option among consumers. The main reason is that mudjacking cost is half the price of a new slab being poured. Mudjacking is also very quick and with little to no demolition needed. The cost of mudjacking is sometimes even less than half the cost of a new slab since concrete raising eliminates the cost of demolition, removal and landscaping.
Patching repairs are generally for pieces of concrete that need one part repaired, large or small. Ground level, vertical and even overhead concrete all need some patching from time to time. If the rebar reinforcement that is embedded within the concrete beam is improperly installed too close to the exterior, a condition known as spalling can occur. Not only does spalling look unattractive and diminish curb appeal, but in time it can lead to a weakening of your foundation. Anchor Foundation Repair can install a concrete repair product to any surface to improve the protection and the look of your concrete beam.
Why does concrete settle?
As stated above, the concrete is related to the soil. A poor soil causes base conditions to weaken and not be in the proper shape to hold the slab. Poor base conditions can also be attributed to:
- Inadequate or Improper Compaction of the Base
- Machine/Traffic Vibrations
- Slab Curl/Rocking Slabs/Need of Slab Repair
What can be done with settled concrete?
Nothing. Settled concrete is an issue that needs to be addressed, not only from an aesthetic standpoint but, most importantly, from a liability standpoint. The Americans with Disabilities Act (ADA) of 1990 defines a ‘trip hazard’ as any vertical change of over 1/4 inch or more at any joint or crack. Since the ADA demands strict compliance, trip hazards represent a legal liability to clients. Cities, school districts, hospitals, private communities, shopping malls, universities, apartment complexes, and other property owners are all extremely concerned with this liability.
Grinding: This is an inexpensive option that is unattractive. Grinding exposes aggregate in the concrete, which makes this unappealing. The integrity and strength of the slab are also compromised when using this method. Slabs that continue to settle after grinding cannot be raised back to original levels.
Replacement: This option is the most expensive. It is also very time-consuming. This method may lead to downtime for businesses, losses of productivity, and lost revenues. The colors will not match existing adjacent concrete.
Raising & Stabilizing: May be done with traditional mudjacking or cementitious grouting. This process utilizes a hydraulically powered pump to install a slurry mix under the slab with enough pressure to compact weak soil underneath and raise the slab for slap repair. Water, fly ash, topsoil, sand, clay, agricultural lime, and cement are materials used to create these slurries. This method, when used on a subgrade that has already settled, adds excessive weight, and may lead to resettling.
