Don Crites, a Colorado native who now lives in Falmouth, Va., created a little reminder of his old home state in his backyard: a 34-foot concrete mountain, complete with five waterfalls, foliage, and a patio. It also features a cave, a snowy peak and a "volcano" where smoke from a gas grill in the cave escapes. The mountain is constructed out of type I portland cement, masonry cement, and sand on a rebar and wire mesh frame. The concrete used in the mountain had a compressive strength of 4000 psi. In areas where water is stored or runs, a silicone was sprayed to seal the concrete. The remainder of the mountain was left to weather to give it a more realistic appearance. Crites isn't sure how much his back-yard lawn decoration cost him, nor does he know how much concrete he used. He estimates he and his employees spent 300 man-hours on the project. Crites' company makes stone veneer out of lightweight sand, gravel, portland cement, and pigment. They have recently expanded business from the US to Japan. The company manufactures about 500,000 square feet of veneer annually. Earlier this year, they shipped more than 4,600 square feet of veneer to Japan where it was used on a Tokyo hotel renovation.
