Mineral raw materials for engineering works
General information
In the earthworks sector for building of engineering objects (road embankments, railway embankments, flood banks, earth water dams, waste disposals constructions and sealing elements, soil replacements, and other) there are used natural and anthropogenic raw materials. Such raw materials are defined as: soils, earth masses for building, rock material in the literature of building area and in the Polish and European standards. Earth masses are used in a native state (raw, natural) or after improvement. Regarding their origin there are the following materials distinguished:
- local raw materials, earth masses (native soils, anthropogenic soils) coming from a construction site, digging or spoil accumulated during the previous earthworks – these materials are used for building in the first place;
- raw materials coming from outer sources (in the case of a local raw material shortage):
- earth masses delivered from outside the construction site e.g. raw materials exploited from sand and gravel deposits, dimension and crushed stones deposits or raw materials for engineering works deposits,
- anthropogenic soils: artificial aggregates, mining wastes, industrial wastes
Data presented below, regarding resources and output, are related only to deposits classified as the deposits of raw materials for engineering works, which were documented according to the Geological and Mining Law regulations and which are intended for exploitation in the case of a local raw material shortage (on a construction site). On a national scale, these deposits supply only a part of the raw material used in the earthworks sector. The majority of a raw material comes from other sources, including deposits classified as “sand and gravel” or “dimension and crushed stones”.
The Geological and Mining Law does not define the limit values of the parameters that defines the deposit of this type of a raw material – the raw material is not listed in the Regulation of the Minister of the Environment of the 1st of July 2015 on the geological documentation of a raw material deposit, excluding a hydrocarbon field (Journal of Laws 2015, Item 987). The usefulness assessment and determining deposit boundaries are based on balancing criteria established by an investor and on regulations concerning building and contracting of earthworks – these regulations concern the quality parameters of a rock material and the technical parameters of projected structure. The scope of tests depends on the raw material type and is predicted use.
Deposits of raw materials for engineering works are often documented for the needs of a particular investment. After its ending, the resources of unused raw material (often useless for other purposes) are crossed out from the registry, and the area is allocated to the purposes not connected with deposits exploitation.
The list of natural raw materials (soils, rocks) of a characteristics allowing to using them directly or after improvement to an earth building construction is very long. It contains i.a.: fragmented hard rock soils and rocky soils; mantle rock soils; rubble and pebbles; sands, gravel and sand-gravel (including: loamy and silty types); loamy sands with an admixture of gravel-rocky fraction (morainal); sandy silts and silts; fragmented soft rock soils; mantle rocks and loamy rubbles, etc. The raw material availability is practically unlimited throughout the country.
There are usually clastic rocks of a clayey-sandy characteristics documented e.g.: silty sands (not meeting the criteria for sand and gravel deposits), mantle rocks, loamy-clayey sediments, but also compact rocks: sandstones, limestones, conglomerates – parts useless for the production of crushed aggregates, allocated from dimension and crushed stones deposits. Typically, the raw materials for engineering works are an accompanying raw material in sand and gravel deposits or dimension and crushed stones deposits. They constitute a main raw material in about &frac13 cases.
Resources and output
The total anticipated economic resources amount to 17.024 million m3. In comparison with 2021 they decreased by 0.176 million m3 (1.0%).
In 2022, there was a geological documentation approved for the new Ostromice 5 deposit (Zachodniopomorskie Voivodeship) in which loams for road embankments compacting are the accompanying raw material in sand and gravel deposit. The resources were established at 0.301 million m3.
There were also 2 new documentations with recalculated resources (supplements) approved:
- Wereszcze Duże (Lubelskie Voivodeship) – there were the resources of the Podgórze deposits included, including 0.130 million m3 of loams – raw materials for engineering works, or for cement production (accompanying raw material in sand and gravel deposit);
- Wyżne-Podwiszówka (Podkarpackie Voivodeship) – the resources were settled and crossed out from the registry, including: 0.017 million m3 of schists and mantle loams (accompanying raw material in sandstone deposit).
The total resources drop amounts to 0.147 million m3.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
The output of mineral raw materials for engineering works amounted to 0.187 million m3 in 2022 decreasing by 0.114 million3 (62.1%) in comparison with the previous year. There were 12 deposits under exploitation.
The economic resources were calculated for 15 deposits. They amount to 8.667 million m3 in total. These resources increased by 2.608 million m3 (43.0%) in comparison with 2021. It resulted mainly from establishing the economic resources for the following deposits: Kostomłoty (2.623 million m3) located in Świętokrzyskie Voivodeship and Wereszcze Duże (0.172 million m3) located in Lubelskie Voivodeship.

Mineral raw materials for engineering works
General information
To the group of mineral raw materials for engineering works there have been deposits often called as “earth masses for building purposes” classified. They are usually clastic rocks of a clayey-sandy characteristic e.g.: silty sands, loamy-clayey sediments and mantle rocks, and solid rocks: sandstones, limestones, conglomerates, allocated from the deposits as not fulfilling the criteria necessary for the crushed aggregates production. These raw materials are utilized in the road industry for the road embankments building and the maintenance of dirt roads surfaces. The loamy-clayey raw material can be used for the packing and reclamation of waste disposals, for hydro-building and other purposes. The usefulness of these raw materials is determined by i.e. their geological-engineering parameters, sealing (isolating) properties and others. Usually, the mineral raw materials for engineering works are documented as an accompanying raw material in sand deposits or deposits of the solid rock materials, covering their worse, defective parts. Only in about 30% of cases are documented as the main raw material.
Resources and output
The total anticipated economic resources amount to 17.256 million m3. In comparison with 2019 they increased by 5.488 million m3 (it means by 46.6%).
In 2020, there was only 1 new deposit documented: Dankowice in Dolnośląskie Voivodeship. Clays (0.179 million m3), “used for the sealing of the permeable grounds for the objects connected with the environmental protection”, are the accompanying raw material to the natural aggregates beds.
There were also 5 new documentations with recalculated resources approved for the exploited natural aggregates and dimension and crushed stones deposits, in which the resources of the accompanying raw material were taken into account – mainly the rocks used for the road embankment building. These are: Wereszcze Duże (0.042 million m3) in Lubelskie Voivodeship, Racibórz II – Zbiornik 7 (0.159 million m3) in Śląskie Voivodeship, Danowo (1.618 million m3) and Kołacz (0.042 million m3) in Zachodniopomorskie Voivodeship, and Devonian limestones deposit Kostomłoty (3.663 million m3 – marls, marly schists and marly greenstones) in Świętokrzyskie Voivodeship.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
The output of mineral raw materials for engineering works amounted to 0.243 million m3 in 2020 decreasing by 0.053 million3 (18%) in comparison with the previous year. There were 13 deposits under exploitation.
The economic resources were calculated for 13 deposits. They amount to 6.364 million m3 in total which accounts for 83% of the anticipated economic and the sub-economic resources of these deposits. These resources increased by 1.560 million m3 (32%) in comparison with 2019.

Total anticipated economic resources amount to 11.336 million m3. In comparison with 2017 they increased by 0.985 million m3 (9.5%).
There were 2 new deposits documented in 2018 with total resources equal 0.886 million m3: Wrzawy-Adam (0.026 mln m3), located in Podkarpackie Voivodeship and Sieniawa (0.860 mln m3) in Lubuskie Voivodeship.
In 2018 there were 3 new documentation with recalculated resources approved for already documented deposits. It resulted in the resources growth in Danowo deposit (Zachodniopomorskie Voivodeship) by 0.121 million m3. However, 2 other documents was elaborated for the resources settlement after the exploitation end – partially depleted Narty and Narty II deposits located in Mazowieckie Voivodeship were crossed out from “The balance…”. It was due to the fact that the express road S7 building process was completed and in the deposits location area there is no demand for sands and loams for road embankments building. The resources crossed out amount totally to 0.179 million m3.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
The output of mineral raw materials for engineering works amounted to 0.330 million m3 in 2018 and increased by 0.150 million3 (83.8%) in comparison with the previous year. There were 12 deposits under exploitation.
Economic resources were calculated for 12 deposits. They amount to 5.101 million m3 which accounts for 86.1% of anticipated economic and sub-economic resources of these deposits.

Usually, resources of mineral raw materials for engineering works are documented as an accompanying raw material in sand and gravel deposits, whereas in only about 30% of cases are documented as the main raw material.
Total anticipated economic resources amounted to 10.351 m3 in 2017 and increased by 1.003 million m3 (10.7%) in comparison with the previous year.
There were 2 new deposits documented in 2017 (located in Świętokrzyskie Voivodeship): Skorzów (0.947 million mm3) and Sukowolska Wola (0.066 million mm3). As a result of the verification and harmonization process, the resources registry was also completed with 2 deposits: Mściwojów I – Pole A and Mściwojów I – Pole B. The deposits were documented in 1996 and exploited for the earth dam building process of the “Mściwojów” reservoir, which was putting into service in 1999.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
The output of mineral raw materials for engineering works amounted to 0.180 million mm3 in 2017 and increased by 0.021 million3 (13.0%) in comparison with the previous year. There were 13 deposits under exploitation. Moreover, for the building process of flood banks there were almost 0.058 million mm3 of the building ceramics raw material from Biecz 1 deposit (Małopolskie Voivodeship) used. The raw material from this deposit had been previously used as a ceramic raw material but due to the disadvantage on the building materials market the raw material lost its value (nevertheless, the deposit is still placed in the chapter Building ceramics raw material). The ceramic factory met the problems with raw material sales, the production became unprofitable and the improvement of the economic results seemed to be impossible. Thus, using the raw material for hydro-building purposes should be rated as quite positive as it allowed to develop the part of Biecz 1 deposit using the existing mine and its infrastructure.
Economic resources were calculated for 10 deposits. They amounted to 3.991 million mm3 which accounts for 94.0% of anticipated economic and sub-economic resources of these deposits. In some cases, economic resources are larger than anticipated economic resources demonstrated in Table 2, because they not only contain anticipated economic resources but also anticipated sub-economic – which are not shown in the collation below.

Usually resources of mineral raw materials for engineering works are documented as an accompanying raw material in sand and gravel deposits, whereas in only about 30% of cases are documented as the main raw material.
Anticipated economic resources amounted to 9.347 million m3 in 2016 and increased by 0.145 million m3 (1.6%) in comparison with the previous year.
There were four new deposits documented in 2016: Narty (0.128 million m3) and Narty II (0.096 million m3) in Mazowieckie Voivodeship, Mlewo IV (0.091 million m3) in Kujawsko-Pomorskie Voivodeship, Rozbark (0.179 million m3) in Śląskie Voivodeship. The resources growth due to these documentations was equal 0.494 million m3.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
The production of mineral raw materials for engineering works amounted to 0.159 million m3 in 2016 and increased by 4.7 times more in comparison with the previous year. The year to year fluctuations of the output are significant and may be caused by the changes of production even from single deposits. In 2016 the growth was the result of an increasing output from already exploited deposits (i.e. Gniewczyna Tryniecka-I deposit with ninefold production growth year to year – 0.070 to 0.008 million m3) and due to the beginning of exploitation from several other deposits.
Economic resources were calculated for 10 deposits. They amounted to 4.095 million m3 which accounts for 88.0% of anticipated economic and sub-economic resources of these deposits. In some cases, economic resources are larger than anticipated economic resources demonstrated in table 2, because they not only contain anticipated economic resources but also anticipated sub-economic – which are not shown in the collation below.

Mineral raw materials for engineering works are usually clayey-sandy and clayey rocks, but also others - sandstones and limestones which do not fulfill the criteria necessary for dimension and crushed stones. These raw materials are utilized in road industry for road embankments building or in waste disposal packing and reclamation. Clayey rocks can be also used for packing and reclamation of waste disposals, for hydro-building and other purposes.
Usually (about 70%) resources of mineral raw materials for engineering works are documented as accompanying raw material - these are the parts of deposits which do not meet the balancing criterias of the main raw material, i.e. parts of sand and gravel deposits with too high ash content or parts of dimension and crushed stones deposits with too low strength.
Anticipated economic resources amounted to 9.20 million m3 in 2015 and decreased by 0.288 million m3 (3%) in comparison with the previous year.

There was a new documentation with recalculated resources for Gniewczyna Tryniecka deposit approved (-75 thousand m3).
Two deposits were crossed out from "The balance…” – Dębnica deposit (Dolnośląskie Voivodeship) and Wyżne-2 deposit (Podkarpackie Voivodeship). Dębnica deposit was documented in 2014 but due to the lack of demand the investor applicated for resources deletion (432 thousand m3). Wyżne-2 deposit has been depleted (remaining resources amounted to 3 thousand m3).
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
Production of mineral raw materials for engineering works amounted to 0.034 million m3 in 2015 and decreased significantly in comparison with the previous year (by 45.9%) (table 2). It constituted only 6.2% of the 2012 production. In all of exploited deposits the raw material for engineering works is only co-occurring and the main raw materials are sands and gravel or dimension and crushed stones.
Economic resources were calculated for 10 deposits and amounted to 4.408 million m3 which accounts for 88.8% of anticipated economic and subeconomic resources.

Mineral raw materials for engineering works are usually clayey-sandy and clayey rocks, but also others - sandstones and limestones. These raw materials are utilized in road industry for road embankements building or in waste disposal packing and reclamation.
Usually (about 70 %) resources of mineral raw materials for engineering works are documented as accompanying raw material - these are the parts of deposits which do not meet the balancing criterias of the main raw material, i.e. parts of sand and gravel deposits with too high ash content or parts of dimension and crushed stones deposits with too low strenght.
Anticipated economic resources increased in 2011 by 2.24 million m3 (36.8 %) in comparison with the previous year.
There were 9 new deposits documented: „Gniewczyna Tryniecka-I”, „Gorzyce dz.308”, „Mały Ubieszyn”, „Męciszów I”, „Munina-Nadsan”, „Orzechowce”, „Pustków-1634/11”, „Sieniawa I” located in podkarpackie voivodeship and „Zawichost-Podgórze” located in świętokrzyskie voivodeship. Only in „Orzechowce” deposit mineral raw material for engineering works occur as the main raw material.
The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.
Production of mineral raw materials for engineering works amounted to 706 thousand m3 in 2011 (436 % of the 2010 volume). The output increased especially in podkarpackie voivodeship due to the building of A4 highway.
