Retaining Walls in Shaler
Shaler Township runs up the hillsides above the Allegheny River, and the grades here are among the steepest residential terrain we work on. Streets like those climbing from Etna and Millvale up into Glenshaw gain substantial elevation quickly, and the properties along them are cut into the slope in a way that makes retaining walls structural rather than decorative.
Steep ground concentrates water. On a shallow slope, rain spreads and soaks in. On a Shaler hillside it runs, gathers in the natural draws and low points, and arrives at whatever is downhill in volume. Walls here routinely deal with far more water than their height would suggest, and drainage sizing matters more than in flatter suburbs.
The other consequence of the terrain is tiering. On the steepest Shaler lots a single wall tall enough to do the job would need substantial engineering and cost, and a properly spaced multi-tier system often makes more sense. The critical word is spaced. Two walls built too close together behave as one tall unreinforced wall, which is worse than what they replaced.

Shaler Retaining Wall FAQs
Are tiered retaining walls a good option on Shaler hillsides?
Often yes, when they are spaced correctly. Tiers reduce the height any single wall has to hold. But if the upper tier sits too close to the lower one, its load transfers into the wall below and the system behaves like one tall unreinforced wall. Spacing comes from the design, not from what fits.
Why do Shaler walls seem to get more water?
Because steep ground sheds rather than absorbs. Water runs down the slope, collects in natural draws, and arrives at the wall concentrated instead of spread out. Walls on Shaler hillsides frequently need drainage sized well beyond what their height alone would suggest.
Can machinery reach steep Shaler properties?
Sometimes, and where it cannot we work by hand. Access is a real cost factor on the steeper streets here, and we assess it at the site visit rather than assuming. Helical anchors are useful on these properties partly because they can be installed with smaller equipment.
