Patios and Walks Gallery Published on by Nate The accent of the Limestone step compliments the Bluestone paving nicely. Little Lime Hydrangeas are starting to establish a great backdrop for perennials. We used Limestone Cobbles to retain existing stone mulch. Limestone wall stone was installed as a paver to match the step. The Bluestone walk wraps the house and continues to a new seating area off the deck. This patio was installed with Unilock materials for the inset and step. Decomposed Granite was installed for the walk with a Bluestone drainage channel. The entryway has two pond mix accent areas installed to provide year round interest. A look at the space after gravel has been installed.
