Q. What is a Segmental Retaining Wall System?
A. A Segmental Retaining Wall system comprises of a set of interlocking stackable block units, which combine to form your wall. A similar principle to that of Lego blocks.
Q. What are the benefits a segmental retaining wall over a poured concrete wall or a wall built from rock and mortar?
A. The primary benefits of a segmental retaining wall over a poured concrete wall or a rock and mortar wall are as follows: Segmental walls are designed to allow for the release of water which prevents hydrostatic pressure (water pressure). Being that they are dry-stacked without mortar, they have the ability to be much more porous and allow for greater water permeability, which will ultimately aid in the life and structure of the wall. Additionally, segmental retaining walls are exactly as stated, they are segmental. The reason this is an advantage over poured concrete walls or rock and mortar walls is that the wall allows for movement in the earth without impairing the integrity or the structure of the wall. A poured concrete wall or a rock and mortar wall is a rigid system that can crack when the ground moves or heaves.
Q. How are segmental retaining walls built and what constitutes the success of a lasting well built wall?
A. Segmental retaining walls generally follow a routine design for construction. Factors that generally constitute a successful wall are as follows: a well compacted footer, the proper backfill, wall alignment as it is being built, and the use of reinforcement, such as geo-grid. However, each wall is designed or engineered according to many factors. These typically include: the height of the wall, the soil consistency, surcharge above the wall, what the wall is retaining, and the placement or location of the wall. A lasting retaining wall should always meet these factors and any other factor that could jeopardize the success of the wall’s intentions on a case by case situation.
