Installation instructions Retaining wall Waxholm

Retaining wall Waxholm - Strong and stable!

This is a strong retaining wall for those who want to build a little higher and more stable. The stones are locked using plastic locking plugs. With these, you can easily control whether the wall should lean slightly backwards or whether it should be completely vertical. For extra stability, the cavity in the stone must be filled with concrete or crushed material. Waxholm can be built vertically up to 60 cm without geonet and 100 cm if geonet is used. If you choose to build your retaining wall with a slope, you can instead build it 100 cm high without geonet and a full 190 cm with geonet. The slope is 4 degrees.

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 in height, net anchoring is not usually needed when the wall is built on an incline. When building a straight wall, it is recommended that the pointed wall does not exceed 0.6 meters in height. When using geonets, nets should be placed every third or every fourth lap, the first geonet should be placed between one of the first laps to create a stable foundation to build on.

Step 1

Dig out an approx. 30 cm deep and 50 cm wide trench for the foundation of the wall. Behind the retaining wall, the same amount must be excavated as the total height of the wall. Put in a fiber cloth.
Top up 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 underground) and compact using a ground vibrator.

step 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 drainage pipes are 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 on the stone with crushed material for weight and stability and install the wall plug for vertical or inclined wall by setting it straight or turning it 90°.

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 service weight. Drive carefully and not too close to the wall so that it risks changing position.

Continue installing 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.

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.

Step 5

Finish the top shift with a row of cover 420x300x70mm. For best stability
it is recommended that uncovering and any corner stones are glued with one of our stone glues CoolTack and StoneGrip . 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.
