Engineered retaining walls are designed for heavy-duty applications—high loads, challenging terrain, and projects requiring certified structural performance. These walls involve specific engineering calculations and are built to handle significant pressure. Standard structural retaining walls are built with proper foundations and drainage for residential slope retention and creating level areas. Both are built to last, but engineered walls are the choice for demanding commercial projects or particularly challenging sites.
A properly built retaining wall with correct drainage and solid foundations can last decades. The key is quality installation—proper base preparation, adequate drainage systems, and using materials suited to Whanganui's conditions. Andy builds every wall to perform long-term, not just to look good initially.
Building consent requirements depend on the wall's height and location. Generally, walls over 1.5 meters require consent, as do walls supporting significant loads or located near boundaries. Andy can assess your specific situation during the quote process and advise on consent requirements for your project.
A standard residential retaining wall typically takes 3-7 days depending on size and complexity. Larger engineered walls or multi-tier systems take longer. Andy provides accurate timelines during the quote process and takes as long as needed to ensure proper construction—because structural work can't be rushed.
