Dry stone construction is a landscaping technique that falls outside traditional masonry and rather pertains to soil management. Dry stone, both today and in the past, is closely tied to the local geology upon which a landscape is established. This technique remains relevant because it is simple and effective. When building with dry stone, a natural drainage system is created, directing water and thereby avoiding major problems such as flooding and water non-infiltration on surfaces.

Dry stone construction is even more important today in the context of climate change, where we experience periods of heavy rain followed by long periods of drought. By using dry stone, we make soils more permeable and capable of absorbing water into groundwater.

The profession of dry stone walling has evolved significantly. Once primarily used for rural and agricultural landscaping, this profession had to adapt to mechanized agriculture, where dry stone is less utilized. Today, dry stone wallers work more in areas such as road embankments, urban space planning, and, importantly, the restoration of traditional structures.

It is essential to distinguish between heritage restoration, which respects traditional techniques and materials, and modern constructions such as roadside barriers. Dry stone, as a landscaping element, plays a crucial role not only in aesthetics but also in soil function and usage.
