Building a retaining wall isn't just about stacking blocks; it's about battling gravity and water pressure. First, you dig a trench for a solid base, often with gravel for drainage. Then, layer by layer, you set your chosen material—concrete, stone, or timber—making sure each row is level and slightly stepped back. Weaving in a perforated pipe behind the wall keeps groundwater from building up and pushing it over. It's careful, heavy work that turns a slope into usable, stable land.
