The timber in the wall must be treated in accordance with all applicable building codes and industry <br />specifications, such as the American Wood Preservers Association (AWPA). <br />2. Dig a trench approximately 14" and 1-2" deeper than the height of the timber, usually 14" deep. Apply <br />1-2" of sand to level the base of the trench. <br />3. Excavate for headers and deadmen into the hill. The size, length and location of headers and deadmen <br />will be design specific. Headers should extend past the wall face 1 % - 2" to add strength and prevent <br />splitting. <br />4. Place and level the first course of timbers using the sand in the trench. Avoid gaps between timbers. <br />5. Lay the second course of timbers over the base course, staggering the seams. Each course should also be <br />set back approximately 1/2" from the course below. <br />6. As each course is added, drive 3/8" galvanized or treated spikes, through to the course below. Spikes <br />should be placed 6-12" from each end with 1-2 additional spikes in the center of the timber. <br />7. Soil should be backfilled behind each course and tamped thoroughly. Place a clean 3/4" angular drainage <br />aggregate 8-12" wide against the wall. A 4" perforated tile should be placed at the bottom of the wall. <br />8. Some subsequent courses of timbers will require headers and deadmen. Headers and deadmen should be <br />placed after each 8' timber in every third course of the wall face or as indicated in the design. <br />9. Headers should be secured to timbers with two spikes in the face of the wall and to deadmen in the soil <br />behind the wall. <br />10. Backfill soil after each course is secured and tamp thoroughly. Compaction behind the wall shall be <br />achieved by at least three passes of a lightweight mechanical tamper, plate, or roller. <br />DESIGN SOILS: SAND, UNIT WEIGHT = 120 LBS/FT3, PHI ANGLE = 30 DEGREES <br />Cross section based on information listed in cover letter. <br />:.::0� <br />6'-0" <br />12" THICK, MIN.
