Retaining Walls solve the need for a change in grade.
Retaining Walls solve the need for a change in grade where space does not allow the grade to simply be sloped, which is the least expensive way to change elevations of the ground. Traditional cast-in-place concrete retaining walls are giving way to the modular masonry variety for three reasons. Modular masonry is less expensive, more attractive and more flexible - literally and figuratively.
Curving shapes are possible, and the dry-stacked blocks adjust to settlement and relieve water pressure in the retained earth.
Walls over 4' high require geotextile cloth tie-backs into the backfill. The vertical spacing and depth of the tie-back will be specified by the modular masonry manufacturer. A specialty contractor is necessary for good results. The top of the wall requires special attention when a guard rail is incorporated.
