Trylinka

[7] Tryliński's patent described a manufacturing process combining concrete mortar with stone fragments to form the paving blocks.

He favoured the hexagonal shape over tetragonal designs, noting that the former eliminated the long straight joints between blocks that typically constituted the roadway's weakest points.

[3] Trylinka was extensively used in the construction of roads in interwar Poland during the 1930s, due to its low cost, durability, and ease of manufacturing—as a variety of stones could be used depending on their local availability, its production was inexpensive and relatively simple.

Unskilled labourers could be hired for the process because the manufacture and laying of the blocks did not require complicated tools or heavy equipments.

[3] In Volhynia, black basalt fragments from Janowa Dolina (present-day Bazaltove, Ukraine) and Berestovets [uk; wikidata] were used.
