Why counter forts are provided in retaining walls?
Counterforts are built into retaining walls (and masonry walls in general) to act as a lateral brace and support the lateral loads that building vertical walls generates. This allows the overall width of the retaining wall to remain slim along the entire length (which reduces the cost) but also braces the wall as needed.Counterforts can also be used to support ancillary elements, such as sidewalks and grade-level improvements, built next to below-grade walls. The counterfort acts to brace the wall and to support the ancillary elements, should the soil backfill placed next to the below-grade wall experience settlement, which is usually inevitable.
