Monumental stonework is almost a lost art. I have kept the tradition alive with the installation of over 3,500,000 lbs. of stonework in locations throughout the world. This has included the careful placement of boulders weighing up to 20 tons apiece.
I practice "dry stone" technique in which mortar is secondary to gravity and fit. This is the most difficult, but structurally sound, method possible. I personally attend to all structurally and sculpturally important details. All mortar joints are either invisible, or carefully disguised. Natural forms and textures are faithfully replicated. The result is a monumental work of art that will endure for generations.
I prefer to use natural rather than artificial materials. The indiscriminate use of fake rocks and plastic plants in theme parks and zoos has resulted in the proliferation of absurd designs that resemble the "set to the Flintstones". Some things, such as plants and rocks, should be real whenever possible. Aside from any other consideration, "letting the materials speak" makes for better art.
In circumstances where the use of artificial stone is structurally or thematically necessary, I am prepared to offer supervisory services to insure the structural and aesthetic integrity of artificial stonework provided by others.
