The edGreen self-build wall includes delivery of materials to the address provided on the order form. edGreen/F2 Facade bv assumes no responsibility other than for the quality of the delivered materials.
Foundation
The edGreen wall is a self-supporting wall. This means you must provide a foundation. If necessary, you can consult a structural engineer.
Wall Height and Length
The wall can be built up to 7 meters long. For longer walls, you must add expansion joints to account for changes in length due to temperature fluctuations. In principle, however, you can also order two separate walls.
The maximum height for a half-brick wall is 1800mm. You can go up to 3.2m, but in that case, you must anchor the wall to the inner cavity wall or another supporting structure.
Irrigation Pipes
When constructing the wall, you must simultaneously install one irrigation pipe/drip line in every third layer and connect it to a downpipe. A drip line must be installed in the top layer.
The downpipe must be connected to the irrigation computer via a (ground) pipe.
As an Outer Cavity Wall
The edGreen wall can be used as an outer cavity wall. The detailing must be finished waterproof in accordance with an outer cavity wall. You can find the general details on the edGreen website.
Anchoring
Generally, cavity wall anchoring is done with 5 cavity ties per m² using (adhesive) cavity wall ties from companies such as Gebr. Bodegraven. You should seek advice regarding the type of anchoring.
As a garden wall
If the edGreen wall is being constructed as a garden wall or other freestanding wall, you can consult an expert advisor or structural engineer. However, you should keep in mind that as a half-brick wall, the maximum height is 1.8m. If you wish to convert it into a brick wall (two half-brick walls anchored back to back), you can increase the height to 3.2m.
Top capping of the edGreen wall
It is recommended to cover the top of the wall with a capping plate made of natural stone, artificial stone, or aluminum, extending at least 20mm on both sides.
Water Connection Point
A water connection point must be located near the edGreen wall. You must provide a water connection point with a non-return valve in accordance with applicable regulations. You can attach the irrigation computer to this water connection point, a tap with a hose union, in accordance with the manufacturer’s instructions (Gardena).
Drainage in Moderate Frost
The pipes are reasonably resistant to light frost. However, in moderate frost, you must be able to drain the water from the wall. To achieve this, you must add an air supply valve at the highest point. This can be opened during frost to allow the water to drain from the pipes.
Irrigation System
Irrigation is based on the water pressure of the mains water supply. You must ensure that this water pressure is sufficient.
Leak Testing for Planting
Once you have completed the wall, including the irrigation lines, it is recommended that you pressurize the lines and test them for leaks before installing the substrate and plants. Repair any leaks before adding the substrate and plants to the wall.
Nutrition
A nutrient pill should be placed in each opening when constructing the wall. These pills are effective for one year. You should add a nutrient pill to each opening annually. To prevent this, install an irrigation system with a nutrient supply between the tap and the edGreen wall.
Outdoor Plants
A list of possible outdoor plants is included in the kit. Plants are living beings and respond to environmental conditions. Take this into account as much as possible when choosing your plants. Indoor Plants
The kit includes a list of possible indoor plants. Plants are living beings and respond to environmental conditions. When choosing your plants, you should take this into account as much as possible.
Adding Substrate and Plants
The best season for adding substrate and plants is from March to June. Because the growing season ends
