Stone Retaining Wall Montgomery County

Stone Wall Montgomery County PA Retaining walls support soil and rock, preventing contact with a building, structure or area. Retaining walls prevent earth from moving downhill or soil erosion by providing support for vertical or near vertical grades. Retaining walls are generally constructed of masonry, stone, brick, concrete, vinyl, steel or wood. Due to newer environmental concerns railroad ties have fallen out of favor as a construction material. Segmented retaining walls are more popular that poured in place concrete walls, or treated timber, because they are more economical, take less to install and are safer for the environment. When planning to have a retaining wall it is important to consider the material being retained, and that it is creating lateral pressure behind the wall because it is trying to move downhill due to the forces of gravity. If not properly designed the forces behind the wall can cause it to topple over or push the wall forward. Also of great importance is the installation of a drainage system to prevent hydrostatic pressure.
