Formwork concreting serves to basically act as mould for pouring concrete in to specific sizes and shapes. It allows concreters to mould the fresh concrete, to whatever shape is specified in design drawings and plans. Read MoreWhat is the purpose of formwork?
Concreters when using stencils and patterns are able to imprint, colour over or add texture to patterns and designs onto the surface of concrete. Uncured concrete will have the concrete stenciling designs pressed or laid out on the top, and then when carefully removed the texture or design stays behind. Read MoreWhat is concrete stamping?
Once fresh concrete has been poured and leveled, a concrete “finisher” works on smoothing the surface, and getting all air pockets and blemishes out. If very few can be seen, and it has even tone or colour, it’s called a Class A finish. Getting a Class A finish is desired for residential concrete or commercial...

PCC – what Plain Cement Concrete is called – typically costs less than GPC – General Purpose Cement. The difference in cost plays a huger part in pricing jobs and commercial concreting projects, and why PPC is the most commonly used form of concrete. Read MoreWhich cement is more costly, GPC or PPC?
Concrete can be poured as thin as 2 inches. Unless the project requires a very thin concrete layer, as concrete will always have more strength and durability if it’s poured thicker. Areas like pathways and walkways or letterbox platforms are where thinner concrete could be used. Read MoreWhat is the minimum thickness for concrete?
In large projects that have wide spans, or in areas that need to have less supporting columns, then a waffle slab is typically used. They can either be for the ceiling or floor slab, to give it much more support, as they use beams that criss-cross and look just like a waffle when constructed. Read MoreWhere is waffle slab used?
In house and garage slabs, beddings or footings, it’s common in the concrete industry to use m10 or m15 grade concrete. M20, which is the next strongest grade, is usually for reinforced steel concrete pours – things like foundation slabs, supporting columns or beams.

A concreter is usually someone that does the main supply and pumping of concrete. Visit: http://www.concreterssydney.net.au Read MoreWhat is a concrete worker called?
In order for concrete to set and be durable and hard as it can be, it must go through a stage called curing. Longer is always better, but at least 7 days can be suitable for concrete to properly cure. It can also cure in temperatures as low as 5 degrees.
