Installation Instructions

STEP 1: Remove all surface vegetation and debris. Select the length of the wall and excavate a trench the length of the wall and approximately 12” from top of final grade. Then place a dense graded aggregate and compact to 95% standard density or modified. It's not recommended to use a pea rock or a rounded type of material on the base.

STEP 2: Place the U Start Base Block™ on the compacted gravel. Level the U Start units front to back as well as side to side. Making sure the units are fully level.

STEP 3: Assemble the Tandem® Wall units by inserting the Tandem Wall connectors into the dove tails. Make sure the front and rear panels are the same length.

STEP 4: Place the assembled Tandem® Wall unit on the top of the U Start Base Block™, making sure that the first course is centered on the base block. Check to make sure units are kept level.

BELGARD.COM | 7


Installation Instructions Scan to watchInstallation Video

STEP 5: Once the Tandem Wall units have been placed. Run a string line along the back of the front or rear panel to assure you are keeping the wall units straight in line.

STEP 6: Place 3/4” crushed rock in between the panels to provide frictional connection and proper internal drainage.

STEP 7: Lightly hand compact the gravel in between the panels for proper compaction.

STEP 8: Place 12” of 3/4” drainage rock behind the rear panel of the wall. This will provide for proper drainage behind retaining walls.


STEP 10: When placing the cap on top of Tandem® Wall, use a construction adhesive to secure the cap to the top of the wall.

STEP 9: Set additional courses of the Tandem® Wall. Making sure that you are keeping the wall in proper alignment. Backfill and compact each additional course.

Designed by others. 4. A geotextile filter fabric seperator is required between the unit drainage material and site backfill soil in any application where free wateris expected upon the wall face such as in a detention pond or along waterways where the high water level may be above the bottom of the wall.Use of filrter fabric shall extend a minimum of 1 foot above the anticipated high water level. 5. A fence, railing, guIde rail/fence or other protective barrier is typically required along the top of all walls as required by the site engineer and local codes.The choice, location, and compliance to local codes of the appropriate barrier system is the reponsibilty of the owner and its site engineer. 6. Backfill is typically onsite soil unless otherwise shown in the plans. (OPTIONAL)7. Geotextile fabric as specified by the designing engineer is shown on the back face of the walls, it is recommended to be used to prevent native soils frominfiltrating into the infill material.

1 Column grid

Final height: 42"

STEP 2

Place the grid on a prepared surface

Make sure the outside perimeter of the grid is clear

STEP 3

Take a panel and slide the supplied connectors into the dovetails until they snap onto the horizontal rod of the grid.

STEP 1

STEP 4

Take another stone and repeat the same process. Make sure you have a corner stone to finish the corner. Once installed, slide the stone along the horizontal axis to adjust the corner.

Connectors:

50 connectors per bag (Enough for 1-42" column)

24” x 24” Cap Unit

STEP 7

At the second row the long veneer on the column needs to be grooved. Set wall block into grooved veneer.

NOTE: You must groove a panel every other row.

STEP 7: GROOVED VENEER DETAIL

Every other row will require a grooved veneer.

OPTIONAL

STEP 6

If you have to cut the grid before installation on the base, you must cut the vertical rod at mid distance between two horizontal rods as shown below.

To integrate a wall into the column set the first course up against the column.

STEP 5

Once you have completed the first two rows, use a square to make sure the column is square and then fill the space with 3/4" clear aggregate. Fill the empty space with aggregates at every row.

TANDEM® WALL COLUMN LAYING GUIDE (CONTINUED):

STEP 8

When starting row 3 place full veneer panel across the top of grooved panel. The wall block in row 3 will butt up against column similar to row 1.

Set first wall course against the column

When you have reached the last row, cut the top portion of the connectors with pliers snippers or just by twisting the top portion with your hands.

STEP 9

IMPORTANTWhen you are starting the second row, make sure the base of the top panel hits the top portion of the connector.

STEP 11

Apply glue on the top of the panels before putting on the capping.

IMPORTANT: The capping must lay on the panels , not on the grid.

BELGARD® - TANDEM WALL™ REINFORCED GEOGRID DEPTHS(NO SURCHARGE)

Notes: Calculations assume a unit weight of 120 LBS/CF Assumed for all soil types. Assumed φ angles for earth pressure calculations are: Select Granular = 34º Silty Sand = 30º and Sandy Lean Clay = 26º Non critical structures with safety factor >1.5. Sliding calculations assume 6" crushed stone leveling pad as compacted foundation material. The information provided is for preliminary design use only. A qualified Professional Engineer shall be consulted. Belgard accepts no liability for the improper use of these tables.
