Standard Rockery Construdion Guidelines published by the Association of the Rockery Contrectors should be Tullowed <br /> 2. Rock material shall be hard, sound, duratle and•free of cracks,fissures and other defects <br /> 3. Rockery construction should sfart as soon as possible after cut bank is completed. <br /> 4. Drein pipes should be wrapped in a layer of non-woven filter fabric and completely embedded in pea gravel. The keyway <br /> trench and drain line should have suncient gradier�t to generate Flow hy gravity. <br /> 5. The facial stones should be as nearly rectangular as p�ssible and stacked tightly against one another with their longest <br /> dimension perdendicular to the face of rockery and to keep voids no more than 6 inches across in any direction. <br /> 6. The keyway trench shall be at least 12 inches deep 3nd free of loose soils and stending water. The base-course stones <br /> shall be set on undisturbed, firm, native soils with an allowable bearing pressure at least 3,000 psi. <br /> 7. Each tacial stone should be staggered with an�firmly supported on two stones below. Facial stones should bs tilted back <br /> at a slope no steeper than 6V:1H. " <br /> 8. Drain rock course should consist of 2-to-0-inch quarry spalls, placQd in lifts after the completion of each course of fecial stones. <br /> ROCK SIZE AND WEIGHT SCHEDULE ROCKERY FACIAL STONE SCHEDULE <br /> Rocic Size Weight,Pounds Avg.Dimension,Ft.
