Once the concrete has been poured, if there is any rain, hail or snow predicated it should be covered with plastic to protect it. Concreters need to be extremely careful when laying over plastic tarps, so that it is not put directly onto the concretes surface, otherwise it could discolour or stain it.

Plain Cement Concrete is commonly referred to as PPC, and is the cheapest type of cement. On the other hand we have General Purpose Cement, or GPC, which usually is higher in price. PPC is the most commonly used type of concrete, as its heaper price makes it more versatile in both commercial and residential... Read MoreWhich cement is more costly, GPC or PPC?
A person that works with concrete can also be referred to as “concrete finisher.” There is a difference however – a worker that does the end levelling and surface smoothing is a “Finisher” whereas the worker mixing the cement, pouring, pumping and guiding the concrete is the “concreter”.

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.
