New Bluestone thermal patio and back steps in Lake Forest, IL
Thermal bluestone is one of the finest hardscape materials available for the North Shore of Illinois — and this project in Lake Forest, Illinois showcases exactly why. National Brick Paver & Stone designed and installed a complete thermal bluestone patio and entry steps for this Lake Forest home, delivering a finished outdoor space that is as structurally permanent as it is beautiful.
Thermal bluestone is a machine-finished natural stone surface that provides a smooth, refined aesthetic while retaining enough texture to deliver excellent traction in wet and icy Illinois conditions. It is the preferred finish for high-traffic surfaces — steps, entry areas, and patios where both safety and elegance are required simultaneously. Unlike natural cleft bluestone, thermal finish eliminates the irregular surface variation of the split face while preserving the natural character and color of the stone. The result is a surface that feels refined and intentional without losing the authenticity of natural material.
For this Lake Forest installation, we used full dimensional bluestone — meaning the stone is cut to consistent thickness throughout, not irregular fieldstone — allowing for precise setting, tight joints, and a finished surface with clean, uniform lines. The patio and steps were set in mortar with fully mortared joints — the only correct installation method for natural stone in an Illinois freeze-thaw climate. Dry-set natural stone in this climate absorbs water, freezes, shifts, and becomes a safety and maintenance problem within a few seasons. Mortar-set bluestone stays locked, level, and tight for decades.
New bluestone entry steps were installed with the same mortar-set standard — built over a poured concrete structural base with weeping cords installed to pull water away from the concrete and prevent moisture buildup behind the stone. Every detail of this installation was executed to ensure that the finished product performs as well structurally as it looks aesthetically.
Bluestone's natural color range — blues, greys, warm tans, and occasional browns and purples — makes it one of the most versatile and timeless materials in high-end hardscape design. It complements virtually every architectural style found across Lake Forest and the North Shore, and it develops a natural patina over time that only adds to its character.
