Assembly instructions Retaining wall Muskö

Retaining wall Muskö is a robust and stylish retaining wall that works great for higher constructions. The wall is assembled using flexible locking plugs. Depending on the location of these, you choose whether the wall should be built completely vertically or with a slight inward slope for extra stability. The hollow stones make the stone easier to handle and are then filled again with crushed stone or concrete for increased durability. Muskö provides a stable wall that holds up to the pressure!

Thanks to the fact that the masonry blocks are hollow, each stone becomes manageable and makes the brick suitable for pulling cables through for lighting, for example.

For walls up to 1 meter high, no geogrid anchoring is usually needed when the wall is built on an incline. When building a straight wall without a geogrid, it is recommended that the straight wall does not exceed 0.6 meters in height. When using geonets, nets should be placed in every second or third lap, the first geonet should be placed between one of the first laps to create a stable foundation to build on. Example walls and their heights can be found at the bottom of this page.

Read our installation instructions below and start your wall construction!

Build Retaining Wall Muskö Step 1

Dig out an approx. 30 cm deep and 50 cm wide trench for the foundation of the wall and the first lap. Behind the retaining wall, the same amount must be excavated as the total height of the wall. Put in a fiber cloth and fill with a layer of crushed rock/crushed stone 0-32/0-40 mm or equivalent. Fill up to the desired height ( 10% of the total height of the retaining wall must be below ground level) and compact using a soil vibrator.

Build Retaining Wall Muskö Stage 2

Level with a finer gravel material ( chips 2-4 ), approx. 3 cm thick layer. Place the first layer of masonry in the center of the excavated trench. On sloping ground, place the first stone at the lowest level. In cases where a drainage pipe is used, this must be placed behind
the lowest blocks with an even fall so that the water is directed away from the wall. To prevent the drainage pipe from becoming clogged, a strip of fiber cloth is placed before the next filling layer is added. Fill the hole in the rock with crushed stone.

Build Retaining Wall Muskö Step 3

Fill in a drainage layer of macadam 8-16 mm or equivalent to a width of at least 15 cm behind the wall. Check that the first shift is flat, or slightly inclined towards the slope. This is to have a margin when the masses behind are packed. For filling behind the drainage layer, the same material can be used as for the foundation, crushed stone 0-32 or equivalent. Compact the underlying material with a light vibrator plate, 80-125 kg operating weight. Drive carefully and not too close to the wall so that it risks changing position.

Install the wall plug for vertical or inclined wall by setting it straight or turning it 90°. If geogrids are used, the first grid should be placed between the first and second shifts. Lay the net over the wall plug so that it catches and is anchored in the wall plug. Stretch the geogrid well and fill with filler material behind the wall, so that the stretch is ensured.

Build Retaining Wall Muskö Step 4 STEP 4

Continue with one or two rows of bricks that are laid together until the next geogrid is laid out. Continuously pack the backfill and fill the cavity in each stone. In case of varying and difficult ground conditions, geonets are recommended even for low wall heights.

Build retaining wall Muskö Seg 5 STEP 5
Finish the top shift with a row Uncovering Wall 420x300x70mm. For best stability, it is recommended that the covering and any corner stones are glued with stone glue such as CoolTack, StoneGrip or similar. If you refill with soil at the top shift, fold up a fiber cloth as a separation between the bricks/covering and the soil to avoid material migration and discoloration of the wall.
Remember not to lay too thick a layer of soil as water must be able to reach the drainage.
