As little as 2 inches is how thinly concrete can be poured. Only when very thin concrete is needed for a custom project like pathways or walkways would thin layers be used – it is always recommended that thicker than 2 inches is best. This way you get better durability and longer lasting stability. Read MoreWhat is the minimum thickness for concrete?
When wide spans are required in a building project, a waffle slab will often be used as these areas have fewer supporting pillars or columns. Used in either floor or ceiling slabs, they consist of beams that criss-cross together – looking very much like a waffle! Read MoreWhere is waffle slab used?
Raft slabs are most commonly used in new homes or extensions, where the foundation is to be put in. They consist of heavy-duty concrete beams that are set in with reinforced steel sections, going in two directions. Once the main pour has been done, this raft style slab will have much more additional strength. Read MoreWhat is a raft slab?
In order to achieve the most durable strength of concrete, a typical ratio is 1 part cement, 2 parts sand, then 3 parts gravel and .5 part of water. These are then all well combined and mixed together thoroughly, and will ensure that the resulting residential concrete or commercial concrete work will have good durability...

For concrete areas such as garage floors or carports, the typical thickness is for concrete to be poured at around 4 inches. For areas that will have large vehicles like trucks or caravans parked then it is usually recommended that the thickness is increased to 5 or 6 inches so that it can best withstand...

For footings, level slabs and bedding slabs, the industry standard is to use m10 or m15 grade of concrete. The next level grade of concrete strength is m25, and usually used for pours over reinforced steels, such as with foundation slabs or supporting columns.

After 28 days concrete is considered to have gone through the optimal amount of time to cure and set. After this optimal duration concrete has been tested to have compression strength of 25 N/mm – hence the m25 refers to a ‘grade’ of concrete strength.

Concrete that is not cured will be weaker, and will crack or even collapse under load. Curing MUST be done with freshly poured concrete in order for it to properly harden and set, making it stable and resist cracking or collapse.

Concrete has to go through a stage called curing, in order for it to properly set and dry out to be it’s most durable strength and hardness. The longer this curing process can be done is always best, but the industry minimum is 7 days. Visit https://concretersauckland.net.nz Read MoreWhat is the minimum curing period for concrete?
The strength of concrete is actually the result of a chemical reaction called hydration. The mixture of water and dry sand and aggregate hardens, sets and evaporates out slowly. What is left is the hard substance we know as concrete. So water is crucial and can often need to be sprayed on top of drying... Read MoreDoes wetting concrete make it stronger?
