Bluestone is a popular natural stone used in outdoor construction and landscaping, particularly for patios, walkways, and poolside surrounds. Bluestone’s fine grained surface and deep blue to light grey color is an attractive option for many homeowners in the Northeast. In this article, we’ll take a closer look at this material as well as what sort of solutions Unilock provides in achieving the charm and authenticity of natural stone.
What is bluestone?
Bluestone is a variation of sandstone with a high feldspar content, ranging in color from deep blue, light gray, blue green to earthy brown, and is also occasionally formed from limestone. As such, bluestone has a fine, granular texture, making it a good non-slip surface suitable to pool surrounds and areas likely to be exposed to moisture or where good grip is desirable, such as stairs, front entrances, and backyard walkways. However, bluestone’s natural composition makes it porous, thus susceptible to water, ice and snow damage, as well as to chemical erosion from the chlorine or salt in pool water. To counteract this, bluestone requires special surface treatment or processing. Traditional bluestone is also susceptible to fading over time as minerals within its makeup oxidize and lighten when exposed to air and sunlight, so the deep blue that initially attracts buyers seldom lasts. The Bluestone we use here in the Northeast is mainly quarried in Pennsylvania and New York, as well as Newfoundland, with the limestone variant being quarried in the Shenandoah Valley, Virginia, but to an increasingly limited extent. Bluestone remains widely available throughout the United States, although availability is subject to quarry output and demand.

The Unilock range of limestone includes the deep blue gray associated traditional bluestone in the form of the Black River and Midnight Shadow variations, with lighter shades being represented by the Hearthstone and Winter Mist variants. Black river and Hearthstone are both smooth, fine grained pavers with deep, even tones, while Midnight Shadow and Winter Mist present a more mottled surface and greater textural variation. For warmer shades of gray, Greyfield and Niagara Valley variations in Unilock sandstone range provide the sleek, attractive quality of bluestone with hints of earthy red and brown undertones.
