People in the old Polish countryside were very particular about maintaining certain rites and preparing protective accessories in their household and the whole farm enclosure. These customs stemmed from pre-Christian Slavic protective rituals, and – despite the centuries of influence of the Christian church – they survived in continuity for as long as the early 20th century in many parts of the rural Poland.
The following informations I’ve translated for you are describing the old protective customs from the historical region of Mazowsze (Eng: Mazovia) located in the north-east parts of the central Poland. The same or very similar customs are common in other regions of Poland, as well as in many other Slavic countries.

Drawing protective or decorative symbols with sand is an old custom from the rural parts of Poland, first described by ethnographers in 19th century. In Polish it’s usually called ‘sypanie piaskiem’ (what translates simply to ‘pouring of sand’). It used to be common to many regions located in the modern-day central Poland. This tradition started disappearing first due to changes of construction materials inside cottages and their surroudings (explained below). Later it died out almost completely during the secular communist rule and the rapid industrialization of the Polish countryside after World War 2.
The co-called ‘sand carpets’ were prepared for religious feasts, most notably for Easter but also for other religious spring feasts, of which many bear traces to pre-Christian Slavic beliefs (read for example: the Green Week or the Polish celebrations of Corpus Christi).
Originally the ‘sand carpets’ decorated only interiors of rural cottages. The custom was surviving for the longest time in those villages that were still using a klepisko (an old type of a hard earthen floor inside houses). Sand poured on such a klepisko was behaving differently and staying longer than on the modern types of hard floors.

Then, the modernized materials started entering Polish countryside, notably during the era of the industrial revolution in 19th century. People started building cottages with the hard floors, much quicker to maintain over the year than the old klepisko type of floor. Sand poured on the new hard floors was swept away easily even with a small blow of draft air – the rural people most likely didn’t feel it works and looks correctly this way and the custom started dying out slowly.
However, in some regions the people started ‘going outside’ with the custom. Many symbols started appearing on the ground and paths in front of cottages.
The custom survived the longest in the region of Kujawy (north-central Poland) where the people were nourishing this old tradition even after the World War 2. Before disappearing, drawing of the sand symbols was noted to be alive also in regions around Kielce, Opoczno, Rawa Mazowiecka and Łowicz, all in central parts of Poland.
The symbols had a temporary character and were made usually only for a day. Those poured inside cottages were prepared in the morning, and were carefully swept away in the evening after the main festive meal. Sometimes the symbols could’ve stayed on the floor overnight, and the ethnographers were noting that the most decorative elements were often ‘drawn’ close to the beds.

Nowadays many ethnography organizations in the mentioned region of Kujawy are reviving the old custom. Events with competitions for the most beautiful designs decorating paths and streets with the sand symbols are held, and they become only more and more popular. They are promoted under a name of ‘Kujawskie sypanie piaskiem’ (transl. ‘Kuyavian pouring of sand’). The same motifs that used to be ‘drawn’ with the sand in this region are also appearing in the regional embroidery, and many motifs created during the contemporary competitions are inspired by the local embroidery and other crafts. They include for example symmetrical flowery forms that are remnants of the symbol of a tree of life.
