Fine sand is suitable for construction, concrete and asphalt mixing, and for the production of various cement products such as cement pipes, chimneys, wells, curbs, etc.
Fine sand is a natural granular material made up of very fine rocks and mineral particles. It is mainly used for plastering cable ducts, stonework and paving. Suitable for coating ditches, before and after laying piping and cables, as well as mortars and primers.
Fine gravel comes from breaking clean rocks. It’s an aggregate with high mechanical strength that does not dissolve. It is used for the production of concrete and asphalt mixing, road construction, level coating, as well as for decorative uses such as aquariums and gardening.

High purity material produced by mechanical processing and crushing of limestone. It is used for building rubble, such as building foundations and for drainage projects.
Building stones come in larges pieces, irregular shapes, and in shades of gray and beige, just as they are sourced from the ground. Usually, craftsmen carve the stones and give them the desired shape. They are suitable for stone houses, masonry walls, flower beds, gardens and generally any outdoor or indoor construction.
Mixed stone is a material that is collected directly from the extracted rock, which includes the entire granulometric size range. The sorting of mixed stones is done with loaders. Depending on the preferences of the project, the stones may be more or less rich in fine-grained material. It is mainly used for rubbing large and deep excavations.
Stone blocks are selected according to their volume or weight, which is determined according to the needs of the project. They are mainly used for the construction of port projects, shielding slopes, streams, rivers, breakwaters, etc.
It is used as an embankment material in the construction of the Surface Effect Layer (SEL). This type of aggregate materials are used for the construction of transitional embankments and specifically in the sanitizing layers of excavations and road excavations.
Aggregate materials such as sand, gravel, limestone and stone consist of stone grains. They are divided into “natural or collectible”, and those that are “breakable” which result from breaking rocks or natural aggregates.
Rocks are classified into three main categories according to the way they are formed:
A. Magnetic, which come from the solidification of a natural silica melt
B. Sedimentary, resulting from the precipitation of the materials, which are dissolved or suspended in a liquid or air and grow in layers of significant size,
C. Metamorphic, which come from the transformation of magmatic, sedimentary rocks under the influence of physicochemical factors
The most common rock used to produce aggregates in our country is limestone. The main reasons are: a) they meet the mechanical strength of the structures, b) they have low production costs, c) they are found in most parts of Greece.
