A material that’s readily available, concrete forms the foundation of almost all structures. As reliable as it is, concrete does crack over time. While a crack or two will not compromise the homeowner’s safety, they are still flaws that we would love to avoid.
However, is this possible? Do we have control over crack lines?
First thing to note
The first thing you’ll need to know is that concrete is made by mixing different ingredients together, with the basics being water, cement and sand. Depending on vendors, the recipes for concrete will differ. The only constraint is what materials are available and allowed in Singapore.
During installation, the ingredients must be thoroughly mixed if quality concrete is to be made. Your vendor needs to ensure this is the case, before applying or laying the screed. If time isn’t taken to get this right, there will be a hollow effect and the entire floor can potentially “pop out”. This will lead to multiple crack lines over time.
Factors that cause cracking
Now, the bad news: concrete will crack, no matter what. It’s only when and how they crack. Environmental factors that affect cracking include but are not limited to hacking works, structural integrity and ground vibration. Homes on higher floors tend to be more vulnerable to crack lines as compared to those closer to ground level.
If an earthquake hits our neighboring countries, it will affect the concrete buildings in Singapore. While this is a rare occurrence, it is still a factor that causes crack lines.
When applying concrete for larger floor areas, time becomes a big factor. Since there are curfews in Singapore, workers cannot complete the entire flooring before it dries.
When this is the case, contractors will leave behind break lines. This is to maintain quality workmanship without causing uneven finishes. More proactive contractors will strategically leave break lines in more discreet areas, one examples being under rooms doors.
Break lines should not be confused with crack lines, as they’re result of work done in stages.
What we think
In short, crack lines will, unfortunately, appear under most circumstances. What you really need are dependable vendors who focus on delivering quality concrete works. This will minimise cracks and keep your concrete floors lasting longer.
