In Hagen, the garden often begins where the terrain starts to rise again. Proximity to the forest, damp soil, and little flat ground lead to a simple realization: the shade sail must cover the usable space, not the largest open area.
Custom sails for narrow hillside terraces in Hagen
An elongated rectangle or trapezoid can complement the flat seating area without extending far into the embankment. Posts should be placed where foundations can be securely constructed and no drainage or support structure is weakened.
Plaster, insulation, railings, extensions, or visible masonry are not automatically suitable attachment points. Before taking final measurements, it should therefore be determined where tensile forces can be safely transferred into the structure. If there is no load-bearing point in the right place, an additional post can be the cleaner solution.
Avoid water drainage toward the hillside
With waterproof polyester, the lowest point must be chosen deliberately. Guiding water directly against a retaining wall or into a basement entrance would be a rather expensive form of convenience.
Foliage and moisture are part of maintenance
More dirt accumulates on the fabric under trees. Accessible installation facilitates cleaning, re-tensioning, and seasonal removal.

Water-permeable or waterproof shade sail in Hagen
The choice of material begins with its use: HDPE for airy, water-permeable shade; PU-coated polyester for additional rain protection. Almost horizontal installation is not an option for the dense version.
You can find in-depth information in our guide Planning gradient and water drainage.
Those who primarily want shade and air circulation are usually well-served with HDPE; rain can drain through the fabric. If a dining or guest area needs to remain usable during a shower, waterproof polyester is an option. In that case, the gradient and water drainage must be determined from the start.
Do not place foundations in softened edges
At the transition from the terrace to the embankment, the soil is often less load-bearing. Post foundations belong where loads can be permanently absorbed – not just where there is a narrow gap.
Plaster, insulation, railings, extensions, or visible masonry are not automatically suitable attachment points. Before taking final measurements, it should therefore be determined where tensile forces can be safely transferred into the structure. If there is no load-bearing point in the right place, an additional post can be the cleaner solution.
Typical areas of application in Hagen
- Hillside terraces
- Plots near the forest
- Small, flat seating areas
- Gardens with retaining walls
In private terraces and gardens, the focus is usually on a clearly defined seating or dining area. For restaurants, daycare centers, or commercial properties, walkways, multiple users, and often multiple sails come into play. In Hagen, therefore, the entire outdoor area is not covered as a blanket rule; instead, only the areas actually in use are shaded.

For the order, the attachment points, side lengths, and, for four-sided shapes, the diagonals are recorded first. Then, the necessary tensioning space is taken into account. The actual fabric dimensions are entered – not just the distance between the attachment points.
