It makes sense to put on a splash guard to protect the facade and keep it looking new for a long time. When planning and implementing, however, a few points must be taken into account.
depth
In addition to the width of the eaves strip, the depth of the splash guard is particularly important. If the protection is designed too flat, the rainwater collects in it and only seeps into the ground very slowly. Until the water has drained away, it presses against the wall of the house, in some cases intensively, thereby stressing it. In addition, shallow ditches fill up very quickly and can overflow, especially in heavy rain. This means that the protection no longer fulfills its function, but puts additional strain on the outer wall of the house through pressure, dammed water and slow drainage.
To ensure that this is not the case, the depth of the eaves strip must be at least 80 centimetres. In the case of a greater water load - for example due to a slope towards the house - and large amounts of precipitation, the depth can also be set to one meter. On the one hand, this allows more water to be absorbed and, on the other hand, the pressure on the house wall is reduced.
Broad
The eaves strip should be at least 20 centimeters wide. The greater the load from heavy precipitation or additionally from the inflow of water from a slope, the wider the ditch running around the house should be. Dimensions of 20 to 50 centimeters are usually sufficient to create an effective protection zone.
Again, the following applies:
The wider the splash guard, the lower the pressure on the house wall.
With a deep and wide eaves strip, the frost protection is higher and the house wall is additionally protected.
excavation
Due to the depth and because the protection should run around the entire house, it is advisable to rent a mini excavator for the excavation. In addition, the following points should be observed:
- calculate the volume using latitude, longitude and depth
- Based on the volume, calculate the need for filling material
- Use lawn edging stones, palisades or metal frames for support on the outer edge
- use a frame in front of basement windows to keep the fill material away from the glass
- Fill in layers of gravel or other filling material and compact lightly
- as a finish, for example on terraces or protection over basement windows, place metal mesh on the frame
Tip:
A frame made of lawn edging stones or metal plates is not absolutely necessary, except in front of the basement window. However, it serves as a support surface for wire mesh and prevents weeds from spreading in the gravel bed.
filling material
The classic filling material for the splash guard is coarse gravel. Due to the variety of materials and colors, the splash protection filling can be selected to match the facade and designed decoratively.
Other options include:
- gabion stones
- basalt
- sand
- gravel
Whether tone on tone or as a color contrast to the house wall - whatever you like is allowed. In this way, the functional strip is not only practical, but also visually enriches the property.
