Concrete slab and wall are everywhere, it is very essential elements for the whole building, maintain it to make sure defects are identified and repaired is extremely important before it causes further structural or other linked problems. Those defects that we need to pay attention to learn and fix it will be listed here today for all of you.
Concrete’s hairline cracks may cause further issues if it is not being cured when it was being discovered, the structure integrity of the building might be affected no matter it is from flooring and wall. Concrete repair contractor in Malaysia always advise home owner or building owner, fix when it is still a tiny issue that allows mini cost and effort to recover it, but general public’s concept is always “wait and see” which subsequently costs more time, efforts and cost to repair it.
Common Concrete Floor Defects
Cracking is the most common problem that we have seen in overall regardless of concrete slab or concrete wall. Few of the reasons why it happens are due to drying shrinkage, subgrade settlement, thermal contraction and others. Definitely, prevention is always better than curing after problem arises; however, achieving best prevention result has to evaluate from few aspects and first of it will be mixture of concrete.
Concrete floor repair contractor Malaysia has wide experience and often recommend users to get from reliable premix concrete supplier in Malaysia to ensure the mixing ratio is optimized and consistent, inappropriate and inadequate concrete mixes strength definitely will cause cracks, it is just a matter of time. Furthermore, unsuitably sited of joints for tension control will most likely cause a future crack.
Concrete floor surface scaling also known as spalling is also quite common among concrete crack origins, it is caused by low surface strength. Technically speaking by most concrete repair contractor in Malaysia is due to insufficient content level of water after overworked on the surface or the bleed water remains on the surface during slab finishing. Other factors that cause surface scaling are improper curing, high content degree of freezable water (also called as late season pours most of the time), inadequate air or no entrainment of air at all can subsequently cause this also.
Concrete that has sufficient air entrainment still scale because of the above reason mentioned just now. Universally, scaled surface of concrete will have depth degradation of 1.5mm to up to 5mm for the 1st year, curing issue of concrete is no longer within control of the contractor and owner. Shrinkage crack commonly does not indicate defects in structure, but radon gas or water molecules will penetrate into the concrete structure. However, inappropriate preparation on site during the pouring of site is ordinarily indicated by settlement cracks and hence further investigation of concrete sample must be done before they turn into trouble that is more serious.
Concrete floor repair contractor in Malaysia who can discover cracking issue when concrete hardens, normally will address it as soon as possible in order to avoid cracks develop into severe problem as time passes, turn into deeper and costly problem to building owner. Foundation materials such as rebar (reinforcing steel bar) or other embedded items might be developed by these settlement cracks. The uplift of water-saturated soil or other exterior deposits due to thermal-caused concrete expansion on weather-caused concrete freezing, that is known as frost heaves are the toughest issue that must be addressed immediately by concrete repair contractor in Malaysia due to its high level of risk.
Moreover, concrete floor repair specialist in Malaysia face a lot of blisters issue that are around Malaysia’s concrete slabs. This happens when the air was trapped underneath the concrete mixture surface that is completely sealed, it can neither evaporate or escape in other ways and subsequently creating bubbles from different sizes, then bumps. This concrete blisters issue must be attended during mixing of concrete by concrete supplier or contractor on-site or at the premix plant in order to achieve maximum prevention. Although blisters would not cause any big issue in the structural over long run, but it is not a concrete defect problem that can be detected easily unless your flooring is exposed and remain raw without any overlayment such as tiles.
According to concrete floor repair contractor in Malaysia, concrete curling is the next concrete defect issue that can be found commonly in the building. Upward curling usually happens in internal slab and theoretically due to the underlayment base has higher temperature and moisture level than concrete slab surface.
While the downward curling is due to the base underneath the concrete slab surface is cooler and drier than the overlaid concrete. In conclusion, the top slab cool or dries and shrinks less or more than the warmer or wetter portion. During the drying stage of concrete, this concrete curling issue can be observed and shall be solved during construction phase before it turns to serious cracks in the upcoming years.
