Earthworks and foundation engineering

Earth works is needed for many construction projects and it plays a particularly important role in infrastructure construction.

Foundation engineering from small projects to large urban development projects

We specialize in foundation engineering, catering to both small projects, like the construction of apartment buildings, and large-scale urban development initiatives. Our company is equipped with modern technology and extensive equipment, backed by a team of experienced professionals.

We implement all areas of foundation construction ourselves, utilizing our own equipment and expert personnel. We specialize in challenging projects in growing urban areas that require special expertise, specialized equipment and precise planning. You can check out the projects we have implemented here.

We understand that schedule, quality and trust are key factors in a successful project. Therefore, we are always seeking the best and most cost-effective solution for our customers, which perfectly meets their needs.

The type of earthworks is selected as needed

Pillar and deep stabilization is used in particular to strengthen soft ground, road, field, yard and street areas. For demanding applications, such as base reinforcement of heavily loaded roads, railways and fields, pile tiles are utilized, which ensure a fully rigid structure.

Mass stabilization, in turn, is suitable for strengthening large, soft and clay silt soils. This method can replace mass changes of up to 4–5 meters, effectively saving non-renewable natural gravel reserves.

Reinforced concrete piling is a cost-effective and traditional bottom reinforcement method used, for example, in street and bridge construction and in building construction. Heavily loaded traffic routes, bridges and buildings often get a solid foundation with the help of pipe and drill piles. Excavator piles, on the other hand, are an excellent solution for sites that require very large loads, such as bridges and machine foundations.

Drill piling, on the other hand, is an excellent bottom reinforcement method when high load-bearing capacity is needed, and beating piling is not suitable due to the quality of the base soil or bottom ratios. Drill piles can be implemented from small diameter piles of 90 mm to large piles of 800 mm. In addition, we have access to low-space equipment that allows us to work in confined spaces, such as apartments, when doing foundation reinforcement work. Drill piles can also be anchored in rock to withstand tensile loads.

Building trenches often requires permanent or temporary retaining walls, either for geotechnical reasons or due to the efficient use of space in urban areas. Support walls are commonly made of steel sheet metal, drill pile set or drill pile walls and can be anchored by rock or ground anchors. Our fleet covers all the most common types of retaining walls and anchors. In addition, we have heavy pontoon vibrators and crane-hanging vibrators that can be used to install steel ponties in difficult soil conditions. If necessary, we can also implement shower-injected waterproofing structures in connection with retaining walls. We also have long experience in designing and dimensioning retaining walls in order to achieve a cost-effective and functional solution.

Jet grouting creates load-bearing and watertight pillars that can be used, for example, to ensure the watertightness of construction trenches, dam walls and reinforce foundations. We can implement foundation reinforcement with low-space equipment at normal room height.

We also offer versatile special drilling, such as rock sealing grouts, for a variety of earth, foundation and building construction sites.

Our equipment includes a wide range of tensioning and jamming equipment, which we utilise in the implementation of tensioned and jammed structures. We manufacture anchors on our own production line according to standards. We implement all retaining walls, pile and foundation anchors, as well as weaving and tensioning work on bridges and post-tensioned structures.
