Arch dams are arches (vaults) laid 'on their side'. The stability of arch dams is mainly ensured by the transmission of the strut (normal force in the arch belts) to the banks. They withstand water head due to three important properties that together ensure their stability: 1) the resistance of its vertical structural elements (which... Read MoreArch Dams
Because you want good strength and durability for driveways, the typical strength used for concreting mixes is the 3000-4000 psi range. This is why it’s crucial that concreters know exactly what the area will be used for, before quoting and ordering supplies, so they can create the perfect mix for the job application.

Unlike asphalt, or tar, concrete can resist weathering actions, and also is able to be more resilient towards chemical stains like motor oil. Concrete is also more resistant to for and humidity as it has such small, or no amounts, of organic content. http://www.concretersbrisbane.com/service/commercial-concrete/ Read MoreIs concrete better than asphalt for a driveway?
Like tat with floor slabs, 4 inches is the minimum industry standard for pumping concrete for a driveway. Non-reinforced is fine for passenger cars, but for heavier vehicles like caravans or work vehicles, a thickness of 5 inches is recommended. Home page .

Putting down gravel or other crushed rock as a base, is always a recommended approach to laying down a concrete driveway path. Doing this prevents shifting and cracking, as the gravel allows water to drain off underground. Read MoreDo you need gravel under concrete driveway?
On Concrete driveways and pathways, experienced concreters can do ‘stamping’ patterns to give a visual, or textural finish. Panels or stencils are pressed into the very surface of uncured cement, and then can be coloured, or left exposed like stones. Read MoreWhat is concrete stamping?
This is usually used for foundation slabs in new homes, or house extensions. It is a reinforced concrete slab that is further strengthened with concrete beams going in both directions put into the main pour. Beams around the edge of a raft slab are often called ‘Edge beams.’ Read MoreWhat is a raft slab?
These can be used in both floor and ceiling slabs. Where projects have large spans, with less supporting columns are to be used, waffle slabs are used to bring more ground support as the base is like a ‘waffle’ in design, with supporting pod beams criss-crossing. Check out more on a concrete house slabs service... Read MoreWhere is waffle slab used?
Concreters need to make sure just the right amount of water is added to their concrete mix. If too much is added it can cause lower strength, cause shrinking and cracking or even reduce it’s durability as discussed by concretersbrisbane.com . It’s critical the correct amount is always added and monitored. Read MoreWhat happens if you add too much water to concrete?
In bad weather conditions like rain, hail or snow it can be concrete works will need to ‘protect’ either freshly poured concrete, or concrete going through it’s curing phase. Care must be taken however as plastic sheeting if laid directly on top, can actually discolour the concrete permanently. Read MoreShould you cover concrete with plastic in cold weather?
