A retaining wall is intended to prevent the floors or buildings of a property from slipping or falling on the ground below. These walls are built using very specific techniques to withstand high hydrostatic pressures. The main materials used are natural stone or most often, concrete blocks. Critical importance should be given to the retaining wall environment to ensure the strength of the wall. This type of construction is very often more technical than aesthetic. Depending on the needs, a variety of blocks are offered by concrete product manufacturers.
