This meant we would have to build up the rear end of the patio to match the higher ground elevation at the front of the house. To support the patio, we used a segmental retaining wall system. To compensate for the slope, our design required two courses of wall blocks topped with a single course of cap

Landscaping a steep hill with a retaining wall prevents erosion and allows you to create beds at the top suitable for planting. Installing the wall is labor intensive due to the weight of the materials and the care it takes to set each block securely, but the resulting structure can last years. If the hill is taller than 4

Sure, retaining walls look like simple stacked stone, block, or timber. But in fact, they're carefully engineered systems that wage an ongoing battle with gravity. They restrain tons of

The majority of retaining walls built today utilize manufactured concrete units, or what is known generically as a segmented retaining wall system. These are actually block systems designed to integrate together into a solid and very strong wall. They are typically less than four feet tall. Early block systems were limited to a
