The simple advantages of a Rockwood Retaining Wall

Fast... Located on the underside of eachRockwood® unit, the 4" x 4" Anchor Bar creates a

mechanical connection with the highest shearresistance in the industry. Plus, Rockwood’s fewer pieces,pinless design and lower weight per square foot reducesconstruction time, labor costs and freight charges.

Simple... “One Unit” construction is a vitalelement of Rockwood’s superior design. Each

Rockwood unit can be made into a 90° corner blockor a half block by simply removing a portion of the unit. Thehalf blocks are used to step down a wall, while the cornerblocks lock into position on 90° corners. No special units arerequired; no special inventories are needed; no shortagesoccur on the jobsite!

Strong... In addition to the Anchor Bar,Rockwood provides a second connection to

geosynthetic grids. Upon assembly, Rockwoodunits automatically create 4" x 5" vertical “stone columns”.When layered with grid, the gravel filled stone columnsprovide a multi-point interlock, resulting in a more uniformblock-to-grid mechanical connection.

Versatile... Variable setbacks, sharp radiusturns, “One Unit” construction, and complete inter-

changeability are all features of the Rockwoodretaining wall. The ability to mix various sizes and colorswithin a wall enhances your imagination without sacrificingstructural integrity. Plus, the Anchor Bar allows you to buildat any setback you desire - from 0° to 7°, providing the only“true” vertical setback in the industry.

Radius Curves

Maintain a Running Bond on a Convex or Concave Radius CurveWhen building multiple courses on a radius curve, begin installation with a block in themiddle of the curve, that is centered on two blocks directly below it. Build the wallfrom the center block out, in both directions. Cut and adhere Universal Caps to followthe contour of the wall.

90º Corners

Add More CoursesFor an outside corner, begin installation from the corner out. Alternate the direction ofthe Corner Units for each succeeding course. For an inside corner, position a block sopart of it is exposed and the other part recedes in the wall. Alternate the direction ofthe block for each succeeding course. Cut Universal Caps at the corner and adhere inplace with Super-Stik.

Install the First CourseLay out the base course. The step risershould be built independently betweentwo sidewalls.

Add More CoursesElevate the trench for each succeedingstep riser. The blocks should for eachsucceeding step riser need to overlap theprevious course by 2". Adhere in placewith Super-Stik.

Finish the InstallationCut the Universal Caps with a masonrysaw so they fit the width of each stepriser. Adhere Universal Cap units in placewith Super-Stik.

Rockwood Tip: Fines are the smaller sand-like particles of aggregate that make compaction possible.

Independent Wall Spacing: The 2:1 RatioAs a rule of thumb, maintain a 2:1 ratiowhen building a tiered wall. If the heightof the first wall is 4’, the distance back tothe second wall needs to be equal to or

greater than 8'. If surcharge loading,global stability and/or poor soil conditionsare present, consult an engineer in regardto the wall design.

Stair Steps

Pillars

Add More CoursesLay four pillar units to create thefoundation. Alternate the direction of theblocks as each succeeding course is built.

Finish the Installation - Coping CapsPosition the coping cap so it is centeredon the pillar. Adhere in place with Super-Stik.

Step 1 - Dig the FoundationExcavate a trench that is 12" deep and 24"wide to accommodate a 6" depth of basematerial and the base course. Compactthe base material and level with a tamper.

Step 2 - Install the First CourseSet and level each unit of the base coursefront-to-back, side-to-side across three-blocks. Align the base course units with astring line behind the tail of the blocks.

Step 3 - Add More CoursesWhen building successive courses, centerthe first block on the two blocks directlybelow it. Using crushed drainage rock,backfill 12" behind each course andbetween the blocks. Compact the backfillas each course is installed.

Step 4 - Finish the InstallationPosition the Universal Caps and adhere inplace with Super-StikTM.

Getting Started

Tools and Materials You Will Need

Creating Half and Corner / Pillar Units

Building a Classic 6 WallBuilding a Classic 6 Wall

Rockwood Tip: A rubber malletmay be used to level and align theblocks.

Rockwood Tip: When usingRockwood’s proprietary Step Tread,no caps are necessary! Step Treadavailable in select markets.

Rockwood Tip: The step riser widthshould be divisible by the width of theClassic 6 unit, which is 18". Rockwood Tip: The sidewalls abutting

the step riser should be built as verticalwalls with no setback.

Rockwood Tip: Inside corners withmultiple courses have an accumu-lated setback that will require"wedge" block to fill the gaps.

Rockwood Tip: Universal Caps mayalso be used to cap a Classic 6 Pillar.
