The solid Concrete Blocks are made up of cement and sand mixture. Solid Concrete blocks are used for constructing walls of homes, gardens, or commercial buildings. These are made up of high-density properties. The solid Concrete Blocks provide strong protection from heavy rainfall or high-speed blowing wind.
Frogged blocks provide better sound insulation, improved loadbearing and greater strength and stability. Although it is sometimes seen as quicker and to lay bricks frog down, this creates air paths that affect the performance of the brickwork.
Hollow blocks, which have holes that take up more than one-quarter (and usually more than half) of their cross-sectional area, are used when building boundary fences and other large structures. The holes make them lighter and can be useful when running wiring or piping through them.
Cover blocks are used to ensure that reinforcing bars or rebars are put into the concrete at the proper depth. In order to preserve the rebar from environmental variables including weathering, erosion and corrosion, the proper depth is crucial.
