Constructing a new concrete driveway will require the use of reinforcements such as steel reinforcing mesh if you want one that will last for years. If you are planning to install a driveway in Australia, make sure you and your trusted contractor will use standard reinforcement and sealing techniques to ensure the durability of your concrete paving. This will not only guarantee a durable driveway but a safe and beautiful one as well. Here are some important points to discuss with your contractor when reinforcing your driveway with steel mesh.
Importance of Reinforcing with Steel Mesh
A problem with concrete driveways without reinforcements is its tendency to crack easily with long use and exposure to the elements. Adding steel reo mesh to concrete paving is a guaranteed way to ensure its durability. The reinforcement acts to keep the concrete intact for a long time. Aside from crack width control, the reinforcements welded into rectangular or squares and produced as flat sheets provide tensile strength to withstand pressure and changes in temperature. Rusting of steel mesh reinforcements is prevented when concrete slabs are applied properly.
A concrete driveway sealer will also provide additional support and tensile strength for driveways that cater to heavy traffic. Aside from these, proper placement of joints, preparation of subgrade and sub-base, and application of polyurethane sheets also help increase the durability of your driveway.
Standard Steel Mesh for Driveways
There are different types of mesh used in construction depending on the purpose and size of the concrete paving. The common types used in Australia for driveways are the SL72 with bars measuring 6.75 millimeters in diameter and spaced 200 millimeters. Meanwhile, other contractors opt for type SL82 with bars measuring 7.6 millimeters in diameter spaced 200 millimeters for plain concrete driveways. Furthermore, they also require type SL92 (with a bar diameter of 8.6 millimeters and with a spacing of 200 millimeters) for patterned concrete. The mesh sheets come in the usual size of 6 meters by 2.4 meters.
