Steel reinforcement or rebar is extremely necessary for the structural stability of any construction project, as it ensures that the building is crack resistant and strong. However, concrete lacks tensile strength and is prone to cracking. The presence of rebar strengthens the concrete and helps to keep it in compression.
There are many different wall knots on the market. Each one is designed to do a slightly different job. The right type of wall cladding should be installed where it is needed and appropriate for its intended use and location.
Wall ties have actually been used in construction methods since the 1800s, and by 1945 had become a standard part of cavity wall construction, a method used in most houses because houses with cavity walls proved to be warmer and drier.
