Concrete Gold Coast-Premium Concreting Solutions

Yes, you can pour concrete on concrete in Australia. However, it is important to first adequately prepare the existing surface before pouring new concrete. This involves hacking off any loose or unsound material that might interfere with the bonding between the new and old layers of concrete. Additionally, for a stronger bond between the two layers of concrete, it is necessary to add an epoxy bonding agent or primer over the existing layer before pouring new concrete. It is also important to make sure that both types of cement used have similar characteristics such as slump value, water-cement ratio, etc., so they adhere properly together. Furthermore, if there are large joints present (larger than 0.3m) then dowels should be placed into them in order to provide shear strength along those seams when pressure is applied during construction activities like lifting and forming up columns et al

Once you have prepared your substrate correctly by cleaning off any loose debris or contaminants and adding appropriate mechanical anchors where needed; you can then proceed with pouring your desired top layer of cement - whether a regular portlandcrete mix or self levelling compound/screed type product/polymer modified product etc., should depend upon what end finish you are looking for in regards to wear resistance plus other criteria such as ease of application/application time required etc..

It is imperative that proper steps be taken prior to mixing & laying down fresh cement because without these preparations done correctly beforehand mechanical interlock will not occur between both surfaces - leading potentially disastrous results later on due different expansion rates & load bearing capabilities between both layers & ultimate failure thereof; which could cause potential undermining/structural damage downstream too..

Concrete Australia is an industry leader in producing a wide range of quality concrete products. The grades or strength of the concrete produced by Concrete Australia are typically categorised by compressive, flexural and tensile strength in Mega Pascals (MPa) - however, it is important to note that there are some variations depending on the specific product desired.

The standard mix designs for each grade can be divided into three main categories:
• Grade N – garden variety applications such as house slabs, retaining walls etc. These mixes usually have a minimum 28 day cylindrical compressive strength of 20 MPa and a slump range from 10-20mm;
• Grade M – more specialised applications such as driveways, footpaths etc. With these mixes you can expect minimum 28 day cylindrical compressive strength up to 25 MPa with slump ranging from 10-40mm;
• Grade S – heavy load bearing applications like industrial floors, bridges or foundations etc., where extra protection against splitting under stress loads is necessary. This grade has required minimum cylinder strengths varying up to 40Mpa with corresponding slumps ranging from 10-60 mm depending on structural design considerations and other factors that may affect performance over time such as exposure to water/freeze thaw cycles when exposed above ground level.

In addition to strict standards for all the grades mentioned above, Concrete Australia also utilises supplementary cementitious materials (SCMs), supplementary additives, cement replacements and admixtures which enable them create unique and often superior products tailored specifically towards individual customer requirements without impacting performance or integrity of end use structures so they last longer than ever before while having minimal impact on environment/durability over long periods with minimal maintenance costs associated along the way due customer satisfaction being at top priorities always!

In Australia, the minimum thickness of a concrete slab normally ranges between 100mm (4 inches) and 150mm (6 inches). The exact thickness generally depends on the purpose of the slab and any additional load that it might be taking. For instance, driveways usually require a minimum thickness of 100mm as they will not typically be taking any extra loading. However, if you plan to use your concrete slab for storage containers or other heavier items then its recommended to pour a thicker than average slab with an ideal range between 125-150mm (5-6 inches).

For industrial applications such as car parks or warehouses, structural designers may require slabs to be up to 300 mm thick depending on how much weight can be applied. Depending on your project's size and scope, engineering design services may be necessary in order ensure that all relevant standards are being met.

It is important to note that there are multiple factors which influence the appropriate concrete slab thickness in Australia including soil type, climate conditions and drainage requirements among others. To ensure your work meets Australian guidelines its always advised to speak with civil engineer about these specific requirements prior to commencement of works.
