With traditional methods, it is common for builders to factor in up to 20% material wastage in the total cost of a project. Adding this up over consecutive projects, wastage can be equivalent to as much as 1 building out of every 5 buildings constructed. But with LGS waste is virtually non-existent (and in the case of a FRAMECAD Solution, material wastage is less than 1%). And, steel is 100% recyclable, reducing the overall environmental impact of any waste created. Additionally, LGS is a ‘dry’ system, which means there is no need to use (often limited) water resources for mixing cement or other materials.
