Rebars or reinforcement bars are extremely necessary for the structural stability of any construction project, as it ensures the building is crack resistant and strong. Concrete however, lacks tension strength and can crack easily. The presence of the rebars reinforce the concrete and helps to hold it in the compressed state. Reinforcing mesh Brisbane is found in a multitude of constructions.

Rebars should be placed in concrete that measures at least five to six inches in depth. They have to be placed either at the centre or a little above the slab’s centre. This is why the thickness and quality of a concrete slab matters. The steel rebar also has to be placed in the correct location for maximum structural benefit. Placing it in the wrong place can cause major structural failures.

Things to Keep in Mind When Placing a Rebar Tie

To begin with, the rebars should be tied properly into a meshed structure before placing the same on the concrete. There are some important points that have to be remembered while tying the rebars.

• The rebar frame has to be placed correctly on the slab, not too high or too low. If it is placed incorrectly then the load-bearing capability will suffer hugely and the structure can develop cracks.
• Professional builders are aware of the basic laws regarding placement of a rebar tie. They will never pour premix concrete in Brisbane on top of a rebar structure or place a rebar structure on fresh concrete.
• The rebars have to be reinforced with the help of steel wires at the main points. This helps in maintaining balance and strength irrespective of the weight of the metal in the structure.
• Professional builders will always use metal wires for strengthening the bars rather than lower quality alternatives.
• The rebars should be secured properly to avoid displacement. The tie wires for steel bar in Brisbane have to be secured at the right points. They should be wrapped in four-pound coils. Ideally, annealed wire of 16 gauges or more should be used. In case of more heavy reinforcement wire, you can even use 14 gauges for holding the rebar in the right position.
• If you happen to be using rebar that has been coated with epoxy, then plastic PVC ties can also be utilised. Some builders use Snap-on ties that can be snapped together using ones hands. This method is less expensive and quite easy.
• Ideally, every intersection of the rebar has to be tied for maximum support. The ties do not actually make the structure strong. They prevent the rebars from getting displaced when the concrete is being poured.
• The tie wires should be placed at the right depth from the surface so that the rebar does not rust. It also prevents the concrete from eroding.

Conclusion:

Rebar tie positioning becomes important when the instructions and blueprints of the construction are not being followed to the ‘t’. If the builder is a true professional and follows the specified number of bars in the design blueprint then there is nothing to worry about regarding the positioning of the rebars. And of course, a specialised builder will purchase the right number of quality bars and from steel suppliers Brisbane for the best possible results.
