The Landscaping IndustryThe elements typically missing in landscape design are stones and rocks,

which provide varying heights and contour that make landscaping inter-

esting and require little to no maintenance. Natural stone and gravel are

some of the most versatile elements available for a landscape makeover.

Installing landscaping gravel can be a very easy, low-maintenance op-

tion for many homes and commercial buildings. You avoid re-mulching

with wood chips every year and the stones won’t wash away.

LEED®, or Leadership in Energy & Environmental Design, is a green build-

ing certification program that recognizes best-in-class

building strategies and practices.

Non-roof LEED® Certification (1 point)

Provide shade with architectural devices or structures that

have a three-year aged solar reflectance (SR) value of at least 0.28. If

three-year aged value information is not available, use materials with an

initial SR of at least 0.33 at installation. (Our gravels have solar reflectance

value of 0.45 or greater.)
