Earthworks
Before the actual construction works can begin, it is necessary to prepare the ground, on which the works will take place. These preparations are called earthwork. Earthworks can be either primary or additional in construction works, both in land or water engineering construction. The purpose of earthworks is ground excavation, moving and moulding the ground. It is first and very important step of every construction.
Earthworks are executed according to requirements and regulations of the particular project. Some of the activities performed are:
- Detaching soil form the ground
- Excavation and moving the ground
- Moving, covering and compaction of excavated material
- Loading and unloading extracted ground
Earthworks can be:
- Linear – involving roads, railroad or pipelines
- Surface – airports or city squares
- Ground excavation – foundations or underground parts
We can distinguish 3 steps of earthworks:
- cleaning: removal of plants, loosening the soil, draining the waste water,
- basic: levelling, ditches, roads
- finishing: they take place at the end of the construction
We also offer roadworks:
cutting, topping up, roadside levelling, digging, desludging of drainage ditches, extensions of existing roads, construction of municipal and housing estate roads, construction of new roads from mineral and broken aggregate, earthworks - road maintenance during winter, supply of sand and road aggregate
