The classic quarried stone wall is made of natural stones, which are more or less regularly joined together with mortar. In this way, a charming appearance in the ornamental and vegetable garden, while at the same time useful tasks are fulfilled. For example, a natural stone wall serves as a stable slope, a decorative bed frame, supports terraces elegantly or loosens up the overall picture of the garden in a creative way as a freestanding variant. The following instructions clearly explain what really matters when you build a break stone wall yourself and grouting properly.
Indispensable for the quarry stone wall is a professional concrete foundation. As a rule of thumb for the Wandfuß applies that the width is about one-third of the height. At the same time, the height of 2 meters should not be exceeded, since in this case a stability certificate is required by law, which must only be provided by a certified structural engineer. How to create the foundation correctly:
- Lift a 80 cm deep strip in the measured width
- Fill this with concrete and reinforce it with a steel grid
- In doing so, integrate the steel mesh into the concrete and not just hang up
- At the end, condense the concrete by gently tapping with the spade
- Repeated testing with the spirit level is mandatory, so that the wall surface runs perfectly flat
Tip: A ready-poured foundation is protected from weathering during curing with a plastic tarpaulin. At high heat, the material should be rehydrated every 2 days to prevent cracks due to drying too fast.
Once the foundation has hardened and the stones are delivered, work can begin. As a mortar for a dry stone wall, trass lime mortar has proven particularly well, as it adheres excellently and does not bloom, so no white flags from the joints drives. If the quarry wall serves as a slope attachment, it gets more stability by tapering on one side to the embankment by 5-10 percent. To build a freestanding natural stone wall, two rows of stones are placed, the column is filled with mortar or concrete. Follow these steps:
- Stretch a string between two stakes for orientation
- Moisten the foundation well with a puff brush to spread the mortar on it
- An optimal mortar bed is 3-5 inches high
- The first stone row wall with the largest specimens
- After aligning and tapping, fill the gap with concrete or gravel
- Then the second stone row in a slight offset wall for more stability
- Cross joints run as straight as possible while avoiding cross joints
Tip: The connection between mortar and foundation is significantly improved if you first apply a layer of tile adhesive and only then distribute the first layer of mortar.
Special case Cyclops wall
If you are one of the DIYers with experience, the creation of a cyclopean wall as a rustic variant of the quarrystone wall should be of interest. The term derives from the Greek word 'kyklos' for circle and is less associated with the one-eyed giants of mythology. The natural stones used here are extra large, sometimes round and as good as unprocessed. Around these Cyclopes are arranged smaller natural stones, so that each wall is unique. As there are no continuous transverse joints during the stratification, special care is required.
For the construction of a cyclopean wall primarily hard rocks come into consideration, which guarantee a special longevity. These types of stone are suitable for a cyclopean wall:
The perfect wall crown
So that at the end of the backfilling of a stone wall can not be seen from above, serve flat natural stones as a last location. If you want to better protect the masonry against the weather from the top and at the same time attach importance to a decorative appearance, you pay particular attention to the design of the wall crown. For this purpose, the dried wall is treated with sealing slurry by applying the material in two passes. In this way, the upper end of the quarry stone wall is additionally sealed and provides a perfect underlay for the cover. The specialist trade offers a wide range of products, ranging from modern variants made of copper or aluminum to ceramic coverings in the form of roof tiles. It is important to note that the selected wall crown extends at least 4 centimeters over the wall so that rainwater can drip off well.
The final in the construction of a dry stone wall forms the grouting. Since more and more mortar is used in the walls of irregularly shaped natural stone, as in the classic brick wall, creating more room for action for the home improvement in the design of the joints. Follow these steps:
- Scratch the joints to a depth of 1.5-2 centimeters with a chisel
- Uncruck the loose mortar with a strong brush and remove dust
- Fill up smaller holes with mortar down to the desired joint depth
- Mix air lime mortar according to manufacturer's instructions
- Moisten the rubble stone wall with a sponge or water hose
- Use the joint trowel to press the mortar into the joints and smooth it out
You can save the effort of a subsequent jointing, if already grouting during the walling. This method also opens up the possibility of working with the decorative as well as extra stable sausage joints. The bulging mortar is shaped around using a template. This not only looks nicer, but also gives a joint more stability so that it is not washed away by the rain as quickly as conventional wall joints. If you do not like the sausage joints, choose the wide joints, which are ideally suited to compensate for the unevenness between the unprocessed natural stones.
With an impregnation you give your home-made stone wall the finishing touches. Recommended products consist of organic silicone resins, are solvent-free, frost-resistant and colorless. Applied with a tassel or a garden spray, they penetrate deep into the pores of natural stones and seal them against the weather. After the first layer has been applied and dried, water should bead off. If this is not the case, repeat the process.
Who wants to play it safe for a permanently beautiful stone wall, the impregnation mixes additives against fungi and algae.
To build a quarry stone wall in the garden and to grout properly, it requires no extensive previous knowledge. As long as the size does not reach dimensions of 2 meters or more, neither a structural engineer nor a master mason is required to build a decorative garden wall. With a solid foundation, reinforced with steel mesh, you create the best conditions for years of durability. Avoid cross-fencing while using a good quality mortar, you are on the right track. If you give your attention to a sealed and shapely mural crown, the natural stone wall also gains in aesthetic value. Last but not least, a skilful grouting gives longevity and a harmonious look to the garden wall created by hand. Take care of the joints directly in the walls, avoid the subsequent work.
