Because actual project conditions vary, final wall design, including the incorporation of geosynthetic reinforcement, must be performed by a qualified engineer While this guide provides general guidelines, installation contractors should refer to construction drawings provided by a qualified local engineer for final specifications. Additional installation information is available online at anchordiamond com. Information includes basic wall construction as well as other applications, including. 90' corners terraced walls • curves • water applications cap placement • fences • guardrails BEFORE YOU BEGIN Advance planning and careful layout at the lob site help ensure a successful retaining wall project • Review the site plan to confirm lot lines, wall location, length and elevations. • Understand on -site soils Ideal soils are sand and gravel. For walls built in clay or poor soils, work with a local engineer to confirm the wall design and the required soil reinforcement Black or organic soils should not be used as backfill • Confirm the location of underground utilities. • Seek all necessary building permits. • Prepare a drawing of the site with the wall location, lengths and elevations. • Plan drainage to prevent erosion or buildup of water behind the watt Consider where the water will drain through the wait, where downspouts will expel water and whether there's an underground sprinkler For walls greater than 3 feet in height, a perforated drainpipe is recommended at the base of the aggregate to quickly remove large amounts of water. See page 19 for more information on water applications • Check the block delivered to ensure it is the correct color. Check the geosynthetic reinforcement to confirm that it's the strength and weight specified in the engineering plans • Be sure to use the right tools. Hand tools include a shovel, 4-foot level, dead -blow hammer, 2- or 3-pound hammer, chisel, hand tamper, hydraulic splitter and string line Power tools include a circular saw with a masonry blade and a compactor. • Always wear protective eyewear Segmental retaining walls typically fall into one of three categories. GRAVITY RETAINING WALL The first category - a gravity wall - is a retaining wall that does not use soil reinforcement. A gravity wall has height limitations specific to each product. An advantage of this type of retaining wall is that it requires a smaller work area behind the wall. A gravity wall relies on the weight and setback of the block to resist the soil forces being exerted on the wall. GEOSYNTHETI C-REINFORCED RETAINING WALL Filter fabric walls, and they are used in larger applications. They require more work area behind the structure. The block of soil is stabilized by introducing reinforcement layers into the soil mass behind the facing units. The larger the stabilized soil mass, the more soil can be retained or held back. The geosynthetic reinforcement in the soil extends past the theoretical failure plane and serves to create a large, rectangular mass of block and soil, restraining the retained soil. ANCHORPLEXT" RETAINING WALL SYST EM Topsoil Filter fabric Level The third category is the AnchorplexT" retaining wall system, which offers a unique, nonconventional solution to problematic wall construction sites. It is a retaining wall built with Anchor products and self -compacting structural backfill specified by ANCHOR DIAMOND Group, and backed by engineering support tools Low - permeable Y developed b Anchor. per soil Use of the Anchorplex retaining wall system completely Reinforced eliminates the need for the construction of a mechanically soil zone stabilized earth zone behind the wall facing and requires substantially less excavation than is usually necessary in grid - reinforced wall construction. \ Geofo ceme'rcif For more information about the Anchorplex retaining wall ref" system, go to anchordiamond.com. pad Drainpipe Drainage aggregate The second category is a geosynthetic-reinforced wall, which needs to be designed by a qualified engineer. There are (theoretically) no height limitations with reinforced retaining INSTALLATION INSTRUCTIONS INSTALLATION INSTRUCTIONS 111P11 ANCHOR DIAMOND Diagram 1—Excavat,on Diagram 2—Leveling Pad 0 iagram 3—Base course Diagram 4—Cora Fill 1. STAKE OUT THE WALL • Have a surveyor stake out the wall's placement. Verify the locations with the protect supervisor 2. EXCAVATION • Excavate for the leveling pad to the Imes and grades shown on the approved plans, and excavate enough soli from behind the wait for the geosynthehc reinforcement material • The trench for the leveling pad should be at least 2 feet wide and a minimum of 1 foot 2 Inches deep, enough to bury the first course below grade, plus 6 inches for the leveling pad Ensure that a minimum of 8 inches or 10 percent of the total wall height (whichever is greater) is below grade. See Diagram 7. 3. LEVELING PAD • An aggregate leveling pad is made of compactible base material of 3/ inch minus with fines • If the planned grade along the wall front will change elevation, the leveling pad may be stepped up by the height of the block (typically 8-inch increments) to match the grade change Always start at the lowest level and work upward. • Compact the aggregate, making sure it's level front to back and side to side Mist lightly with water before compaction, if needed. See Diagram 2 4. BASE COURSE • This is the most important step in the installation process • Begin laying block at the lowest elevation of the wall, whenever possible Remove the rear lip of the block by hitting with a hammer and chisel from the back so that the block will lie flat on the leveling pad • Place first block and level, front to back and side to side, lay subsequent blocks in same manner. • Place the blocks side by side, flush against each other, and make sure the blocks are in full contact with the leveling pad. Level front to back and side to side • Place soil In front of the base course and compact. Base course should be buried. Continue to fill and compact after each course is laid • If the wall is on an Incline, don't slope the blocks. Step them up so they remain consistently level • Use string along back edge of the block to check for proper alignment. See Diagram 3. S. CONSTRUCT ION OF THE NEXT COURSE • Fill cores and voids between blocks with A -inch clean drainage aggregate prior to laying the next course of block. Clean any debris off the top of the blocks • Place the second course of blocks on top of the base course Maintain running bond Pull each block forward as far as possible to ensure the correct setback. • Backfill with drainage aggregate directly behind the block, adding 6 to 8 inches at a time Add soil fill behind the aggregate. • Compact before the next course is laid Don't drive heavy equipment near the wall Self-propelled compaction equipment should not be used within 3 feet of the back of the wall • You'll need partial units to stay on bond. A circular saw with a masonry blade is recommended for cutting partial units Use safety glasses and other protective equipment when cutting. See Diagrams 4 and 5 6. DRAINAGE DESIGN • Each protect is unique The grades on the site will determine at what level to install the drainpipe Place the drainpipe (4-inch perforated piping) so water drains down and away from the wall into a storm drain, or daylight just above grade • Fit[ in the area behind the blocks with clean drainage aggregate, at least 1 foot from the wall You may need to place and Backfill several courses to achieve the proper drainage level. • The outlet pipes should be spaced not more than every 50 feet and at low points of the wall. In order for the drainage aggregate to function property, it must keep clear of regular soil fill See Diagrams 6 and 7. Diagram 5—NexbCourae Constructlon Diagram 6-0rainage Diagram ]—Backfill Diagram 8—Compaction 7. COMPACTION • Shovel the backfill soli behind the drainage aggregate and compact the backfill with a hand - operated compactor Make surethe aggregate is level with or slightly below the top of the base course • Continue to fill and compact after each course is Laid See Diagram 8 8. REINFORCEMENT (IF REQUIRED) • Geosynthenc reinforcement is recommended for walls taller than 4 feet or walls situated in poor soils, supporting a driveway, etc. Consult an engineer for design assistance • Check the wall construction plan to determine which courses will need reinforcement Clean any debris off the top layer of blocks Measure and cut the reinforcement to the design length in the plans The reinforcement has a design strength direction, which must be laid perpendicular to the wall • Place the front edge of the material on the top course, 1 inch from the face of the block. • Apply the next course of blocks to secure it in place. To keep it from wrinkling, pull the reinforcement taut and pin the back edge in place with stakes or staples • Add drainage aggregate behind the blocks, then add the backfdl soil and compact it. • Correct placement ensures that you maximize the connection strength and keep the batter consistent. A minimum of 6 inches of backfdl is required prior to operating vehicles on the reinforcement 9. CAPPING A WALL • Always start capping from the lowest elevation If the wall elevation changes, caps can be stacked where the wall steps up • Lay caps at the elevation change and work back toward the previous step up. Cut caps with a diamond -blade saw to fit, as needed • Carefully glue with a high -strength concrete adf— • If the wall is on an Incline, don't slope the blocks Step them up so they remain consistently level. • Use string along back edge of the block to check for proper alignment See Diagram 3 10. FINISH FRADE AND SURFACE DRAINAGE • Protect the wall with a finished grade at the top and bottom To ensure proper water drainage away from the wall, use 6 inches of soil with low permeability and seed or plant to stabilize the surface • Consult the wall design engineer if water may be directed behind the wall. If needed, create a swale to divert water away from the wall This will minimize water seeping into the soil and drainage aggregate behind the wall. 11. SITE CLEANING AND RESTORATION • Brush off the wall and pick up an debris left from the construction process. Notify the job superintendent in writing of the completion and that it is ready for final inspection and acceptance • Planting vegetation in front and on top of the wall will help reduce the chance of erosion • Following these best practices for construction will ensure the success of your ANCHOR DIAMOND Group retaining wall These instructions are meant as general guidelines Site -specific conditions may warrant additional installation requirements. • ANCHOR DIAMOND Group recommends you consult a professional engineer to design walls over 4 feet high, and have compaction tested by a qualified geotechnical engineer SAFETY NOTE: Always use appropriate equipment, including safety glasses or goggles and respirators, when splitting, cutting or hammering units RUNNING BOND STRAIGHT WALL Proper installation of an Anchor' retaining wall requires that running bond be maintained. Running bond occurs when the blacks are centered over the vertical joints of the previous course This adds to wall stability and makes the wall aesthetically beautiful. OUTSIDE CURVED WALL Any wall that is not perfectly straight will eventually run off bond When this happens, skip a block position and place the next block into the next place where it is back on bond. Measure the remaining gap and cut or split' a block to fit Once the partial unit is in place, glue with a concrete adhesive. Partial units must not be less than 8 inches long, and should not be placed directly on top of each other. If the gap is larger than the length of one block, divide the measurement by two and put two partial units in place Tip It may be possible to run the off -bond block into the soil bank to avoid cutting of partial units "To split a block, use a hydraulre sptitter or split manually by using a hammer and chisel to score the block on all sides Pound the chisel on the same line until the block splits. If partial unit sides are not exposed, use a circular cut-off saw with a masonry blade to achieve a tighter tit STEP 1- PLACE REINFORCEMENT SO LITTLE OR NO OVERLAP OCCURS IN THE RADIUSAREA IF OVERLAPOCCURS PLACE2103 �wwr rnwa.e.wc w+�Trrl FII%�I I I I yl I I I I I it I I- I I I I 1! „.FyPasEDAWxKrr Tn„rEw LI I I I I I I I •E*� �••»A.� II I I I I I I I noAUT waaaAS NeEceoro NNM+�N R�/yg9pq \ LrNweo aA.aL `rawrrwrre+ee aA+MAAA�Au uvuHarin PRINCIPLE REINFORCEMENT DIRECTION INCHES OF SAND BETWEEN THE - REINFORCEMENTLAYERS.

Water collected from the drainage fill behind the wal must be able to drain down and away from the wall into storm drams or an area lower than the wall, either at the end of the wall, via a carrier drain or through drainage weep holes. FIRST COURSE If the wall is longer than 50 feet, drainage weep holes must be Installed through the wall face, no more than 50 feet apart.

Next, determine the proper placement of the reinforcement by dividing the proposed height of the wall by four. This represents the distance that reinforcement must extend beyond the front of the adjoining wall Measure this distance from the front of the adjoining wall and begin the grid placement here. Make sure the grid is placed 1 Inch back from the face of the block below and runs along the back of the adjoining wall EXAMPLE: If overall wall height is 4 feet, the reinforcement extension would be 1 foot. Place the next section of reinforcement on the adjoining wall The reinforcement must not overlap and should lie flush with previously placed sections. Once reinforcement is in place, the next course of blocks can be installed SECOND COURSE WITH REINFORCEMENT The first section of grid on this course is placed using the same formula that determines placement in front of the adjoining wall Alternate the reinforcement extension on each course where reinforcement is required.

When building an inside curve the reinforcement will fan out, producing slight gaps In order to ensure 100 percent coverage, additional lengths of reinforcement are used to fill those gaps on the next course of blocks Don't overlap the grid on any given course. FIRST COURSE WITH REINFORCEMENT Cut reinforcement to the lengths specified in the wall plan Lay segments of reinforcement within 1 inch of the face of the wall, making sure that the strength direction of each section is perpendicular to the wall face. Avoid overlapping the reinforcement by separating each section NEXT COURSE Place the next course of blocks, marking their backs to identify unremforced areas. This step is important because when this course is backfdled, it's impossible to locate the unremforced areas Use the marked blocks as a guide, placing subsequent sections of reinforcement to overlap the gaps left on the previous course.

Install any sleeves according to the wall plan. Sleeves should be at least 1 inch larger than the posts to allow for concrete and grouting. Walls should not be completed and sleeves then 'punched' through the already installed backfill and reinforcement layers after construction is complete This may result in damage to the reinforcement grids and lead to subsequent failure of the wall. Sleeves should be installed and held in place before any reinforcement the sleeve passes through is positioned, with the watt blocks, drainage material and backfill being installed and constructed in accordance with the instructions found elsewhere on anchordiamond com Carefully cut the reinforcement cross straps to allow the reinforcement to fit around the sleeve without distortion or additional tension being introduced to the grid when in its final location. Ensure the reinforcement grid is installed in accordance with the instructions found elsewhere on an chordiamond.com. Grout the guardrail posts into each sleeve after the wall is built FENCES The specific dimensions of the fence and fence post spacing are required to accurately determine the placement of the sleeves, Provide at least 1 inch clearance between the inside of the sleeve and the outside of the post to allow for mortar and grout. Install the sleeves according to the watt plan during the construction of the wall If the fence is at Least 3 feet back from the watt face, generally no additional reinforcement is required If the fence is installed within 3 feet from the face of the watt, there may be some load transferred to the wall from wind, snow or pedestrians Additional reinforcement around the fence sleeves may be needed Consult a suitably qualified engineer before installation takes place.

The upper wall must be built a distance away from the lower wall of at least twice the height of the lower wall In addition, the upper wall must also be equal to or less than the height of the lower wall. Exceptions to this general rule include weak soil conditions or where slopes exist above, below or between watt tocations For example, if the lower terrace is 3 feet 4 inches tall the distance to the upper terrace must be at least 6 feet 8 Inches, and the upper watt must not be higher than 3 feet 4 inches Proper dra wage is vital to maintaining stable, long-lasting terraced walls. Drainage pipe must be installed so that the water is directed around or under the lower wall (Never place the drainpipe outlet for the upper wall above or behind the lower wall.) DEPENDENT TERRACED WALLS When the distance between the lower and upper walls is less than twice the height of the lower watt, the walls become structurally dependent on each other. In this situation, it is important to take global stability ( the resistance to overall mass movement of the whole SRW system in a circular or sliding mode) into account, incorporating additional reinforcement -and longer layers -into the wall plan In addition, structurally dependent walls require even more excavation, back fi It and time For dependent walls, consult a qualified engineer i DIAMOND FRO'LOCK I BLOCK , 12' (MIN) OF FREE- DRAININGAGGREGATE CAP BLOCK — ..

Install the leveling pad and the base course, the drainage aggregate and drainpipe. Wrap the fitter fabric up the face of the wait to the top of the base course Place soil fill in front of the wall and fully compact, trapping the fitter fabric against the front of the wall Install a second layer of fitter fabric to the front of the wall, with sufficient width to allow the fitter fabric to extend up the face of the wall to the depth of the layer of larger stones required to prevent scour along the base of the wall. Install a minimum of 3 inches of sand over the filter fabric, before installing the layer of larger stones. Use the layer of larger stones to trap the fitter fabric against the face of the watt NEXT COURSE Continue construction of the wall. A fitter fabric should be installed between the drainage aggregate and the reinforced -soil zone for the full height and length of the wall This prevents any clogging of the drainage fill by fines from the reinforced zone.
