Assembly instructions Haga Mini

A small wall that gives great results!

Haga Mini is built with simplicity and works great for retaining walls up to a maximum height of 1m in the garden. The rear edge of the wall is fitted with a heel which causes the wall to tilt backwards during installation. The front of each wall block is cracked and therefore gives a rough surface that takes on a natural stone-like character and beautiful structure. The wedge-shaped block is easily assembled by stacking it in half joints, no locking plugs, geonets or other anchoring products need to be used. Haga Mini's great strength is its flexible format and light weight, as well as the great flexibility in the assembly itself, as you can quickly swing the wall and go from straight to undulating walls in the garden. For a really stylish solution and a cheeky finish, the cover can be installed as a top stone.

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. Add a fiber cloth as a soil separator and lay the foundation for your brick.
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 preferably a whole block of masonry) and compact using a soil 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 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.

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.

STEP 4
Continue with one or two rows of bricks that are laid in dressings and backfill behind them. Continuously pack the back filling for as stable a result as possible.

Then continue to build up your wall until you reach the desired height level.

STEP 5
Finish the top shift with a row of reveal. Top stone and cover are available in a wide selection in both concrete and beautiful granite. Granite has become increasingly popular to mount on the wall as it provides a beautiful detail and framing on the wall. For best stability, it is recommended that the top stone be glued with one of our stone adhesives CoolTack 286 or PU StoneGrip 598. If you refill with soil at the top shift, fold up a fiber cloth as a separation between the brick/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. A common solution is to lay decorative stone just behind the wall and its capstone to create a decorative surface.
