Installation instructions Mursten Visby - Retaining wall

A classic tumbled masonry block for construction in both free-standing walls and lower retaining walls. The practical measurement means that you can easily mount the stone in half joints and at the same time enable nice 90 degree corners without having to process the stone. The blocks are advantageously glued together using Stenlim and then lie firmly. The tumbled surface gives an antique look and a real garden feel. Mursten Visby is manufactured in several colors where only imagination and creativity set limits. An affordable brick block that can be used throughout the entire garden project. Low retaining walls! Freestanding walls and frames! And also as curbstone around flagstone surfaces and fun stair constructions.
Visby is a lovely series of concrete series with tumbled products and you will also find flagstones in different formats and stylish curbstones in the series.

Step 1

Dig out an approx. 30 cm deep and 50 cm wide trench for the foundation of the wall. Behind the retaining wall, as much must be excavated as the total approximate total height of the wall. On lower walls, it is good to use something extra so that the backfill does not become too thin. Place in a fiber cloth at the bottom and fill with a layer of crushed rock/crushed stone 0-32/0-40 mm or equivalent. When you place the fiber cloth, it is good if you overlap the cloth where the joints are, so that the cloth does not slide apart over time.

Fill up to the desired height (10% of the total height of the retaining wall must always be underground, but a whole stone is clearly recommended as this provides a more stable foundation for the wall to rest on) Compress your filling mass using a soil vibrator.

step 2

Level a bed with a finer gravel material ( chips 2-4 ), approx. 3 cm thick layer. Place the first layer of masonry in 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 in an approx. 15 cm deep drainage layer of macadam 8-16 mm 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 soil vibrator and drive carefully and not too close to the wall. If you drive too hard and close, there is always the risk of changing position on the bedrock.

Step 3

Continue with the next masonry shift and mount the stones in half-joints. Glue your bricks together with concrete glue and continue to backfill with crushed rock and the draining layer of macadam. Repeat the turns with the soil vibrator, making sure the backfill is properly compacted.

Step 4

If you want to finish with soil and lawn or mulch soil behind the top stone of your wall, we recommend that you fold up fiber cloth also behind your top layer of brick and cover the soil behind the stone. This is to avoid moisture migration and discoloration of the soil in the top layer of wall.

Mursten Visby's recommended heights:

Vertical retaining wall mounted with concrete glue: 42cm above ground (3 shifts)

Inclined retaining wall mounted with concrete glue: 56cm above ground (4 shifts)

* In some cases, a geogrid can be used to strengthen the construction of the wall and thus also enable a slightly higher construction of the wall. In these cases, the geonet is placed between the stone shifts and glued in place using the concrete glue. The geonet is then rolled out over the packed surface behind the wall and embedded in the masses when the next course is assembled. We recommend that geonets are used at every stone shift in the retaining wall in this type of construction and that you contact us for advice on your wall construction and height.

If you want a tumbled brick for a higher construction, we mainly recommend our stylish retaining wall Gripsholm. Where construction with locking plugs and geonets can lead you all the way up to 150cm. This wall gives you the opportunity to choose between Tumbled and Cracked/Tumbled front surface.
