THURSDAY, APRIL 22, 1999 Home landscaping often attempts to develop an in- formal appearance. A rock wall can increase the beauty of the site as well as add to the area's utility. Uneven terrain can add visual interest and variety in the landscape if handled properly. Changes in grade may be used to delineate utility, recreational and gar- dening areas, as well as to provide proper surface drainage. Color and shape of rock used should be carefully incorporated to unify a de- sign with the overall land- scape. There are several things you should consider in constructing rock walls to reduce grade or slope. The wall will usually be more stable if developed into a gentle curve. In in- formal landscaping, curved THE NEW TANNER ll HOME & Saber CHECK GUT THE DEALS FOR THE SEASON! to four feet high. Soil pro- file for retainer rock wall construction. If walls must be more than four feet high, a solid footing is required. Con- struct the footing of con- crete 24 to 36 inches be- low ground level. Footing width should be one-fifth the wall height and should be centered under the base rock. Terrace walls over 5- 6 feet high to create walls more in scale with humans. Type and quality of stone are important. Some stones are very hard and resist weathering, while others such as shale are soft and will crumble. Materials you can use for wall construc- tion include: native stone, ledge rock, brick, tile, bro- ken concrete, concrete blocks and railroad ties. Use the largest, flattest lines tend to be more pleas- ing to the eye than straight lines, while straight walls may need to be bolstered with columns or jogs to im- prove stability. Consider the site or lo- cation of the wall and fac- tors such as: Soil type. How easily does the soil wash? Will soil pack firmly? Does soil have the ability to grow healthy plants? You should determine drainage and rate of flow as well as the concentration points of water runoff to protect a wall from erosion or under- cutting. It ray be neces- sary to consider water di- version around a rock wall when shaping the area for a wall. A stone retaining wall will be made stable and last longer if a concrete foot- ing is provided. However, retaining walls can nor- mally be laid safely up to three or four feet in height without concrete footings. If soil is used as the wall foundation, tamp it to a depth of 12 to 18 inches. This will generally provide a stable base for walls up rocks to form the wall's base. Lay this base rock at least to the depth of one rock below the soil surface. In some cases, it is desir- Use the widest stones on the lower portion of the wall with smaller rocks for } the top.
