Infinity edge pool – Instead of installing a swimming pool base, many homeowners are willing to pay a little (or a lot) extra to mimic the experience of vacation in their backyard. Perhaps the prime example of the trend is infinity edge pool, which is also known as a negative edge pool. The pool has a short wall on one side, allowing water to spill into the catch basin (or weir) below. The point is to create an optical illusion, making it seem like water blends into the horizon. It is easier to demonstrate than describe:
An infinity edge pool is a reflection or a swimming pool where the water flows over one or more edges, producing a visual effect of water indefinitely. The pool is often designed so that the edge appears to merge with a larger body of water such as the ocean, or in the sky. They are often seen in exotic resorts and exclusive estates, in advertising, and in place other luxury.
Infinity edge pool is very expensive and requires extensive structural, mechanical, and architectural detailing. Because they are often built in hazardous locations, structurally sound technique is paramount. High cost pool is often found in the foundation system that anchors them to the hillside.
