When Does Concrete Need to be Reinforced?
When working with concrete is difficult to know what reinforcement method is best. Without reinforcement, concrete doesn’t stand up properly, cracks and crumbles under high pressure. When using concrete in different situations you need to work out what would be the best reinforcement method to use that will be cost-efficient. Making sure you choose the right reinforcement first time is very important, saves time and hassle of having to replace it after a few years due to cracks. Be aware that certain materials are required for certain projects under building regulations.
The Main Types of Concrete Reinforcement are
Steel Fabric Mesh Reinforcement
Steel Fabric Mesh Reinforcement Sheets are designed to be immersed into the concrete while the concrete is setting allowing for stresses to be transmitted between the two materials, therefore, reinforcing the concrete, increasing the overall strength of the structure and assisting in the control of cracking.
