A wall for a lifetime, and why your "well-built" wall failed.
Everyone has seen a wall that failed. Leaning, weeping, shedding its cap. Built to last a lifetime, undone in a decade. Often among the largest lines in a landscape budget, spent, essentially, on substrate.
A retaining wall is one of the most substantial impositions we make on the landscape, holding back material and stormwater to create a developed and inhabitable space. It is a prominent representation of form as function. Walls impart a sense of permanence by necessity, constructed of heavy stone or block. Available materials have long dictated an aesthetic the rest of the site must harmonize with or respond to, and as such, they're expected to last a lifetime. And then they often don't.
What separates the wall that fails from the wall that endures is everything you never see: engineered footings, reinforced structure, gravel and drainage giving water somewhere to go besides through.
Modern construction techniques relieve both premature failure and aesthetic constraints. Precise calculation of load, and often building code, enable a choice of finished materials unavailable in times past, and allow these structural elements to marry cohesively with the emotional tone of the design.
The finished wall looks beautifully simple. What makes that possible is anything but.
