What is a Weir Wall?

When swimming pool design includes an infinity or vanishing edge, the term weir wall will also be used in the discussion. A weir is a barrier across a body of water, designed to alter its flow characteristics. Weirs are commonly used to alter the flow of rivers in order to prevent flooding and to help make rivers easier to navigate.

In the case of a swimming pool, weir walls take the form of obstructions which cause water to pool behind them, while allowing water to flow steadily over their tops. So “weir wall” is the technical name for the visible wall that forms part of the exposed end of a vanishing edge design.
