Company Profiles Stroyinject JSC was founded in 1960 and specializes in geotechnical engineering. In its existence of over 50 Year :s the company has participated in the construction of all major civil and infrastructure projects in Bulgaria. Since 1999 Stroyinject is a private company and has expanded its size and operations significantly. Currently, the company takes part in major infrastructure projects such as: the metro construction in the city of Sofia, the strengthening and stabilization of excavation pits for big commercial centers and buildings in Bulgaria, as well as fortification of landslides in the Black Sea region. Stroyinject specializes in civil and infrastructure projects: road, railroad facilities, hydro-technical facilities, bridge foundations and strengthening of excavation pits, landslides etc.
Company Profiles • Diaphragm walls • Cast - in piles, incl. CFA • Sheet retaining walls • FRANKIPILE® NG /New Generation/ • Grouting works • Soil consolidation • Micro piles • Strengthening of excavation pits, landslides, foundations of buildings, underground parking structures in dense populated urban areas. • Drainages and wells Activities:
CompanyProfiles Adval JSC was founded in 1993. The company specializes predominantly in tunnel construction and strengthening structures. Adval is the first company in Bulgaria to adopt and apply the New Austrian Tunneling Method. The company performs anchors, drilling and grouting works and sprayed concrete. In partnership with other well-known European companies and also individually, Adval participates in tunnel construction work in Germany, Spain, Greece and Bulgaria. Since 2008, the company has been working as a main contractor in the metro construction in the city of Sofia. In just less than twenty years Adval has executed the construction of over 50km metro (subway), highway, railroad and hydro technical tunnels.
Company Profiles Activity: Tunnel construction • Tunnel construction according to the New Austrian Tunneling Method• Tunnel construction according to the Top - Down Method (Cut and Cover Method) Drilling and grouting works • Drilling and grouting works for construction of dam walls• Consolidation of soils• grouting works Anchoring • strained rope anchors for fortification of landslides, roads, anchoring of dam walls.• Rope Anchors for fortification of landslides, deep underground excavations including pile construction, diaphragm walls and sheet retaining walls.• Soil nails for fortification of underground excavations. Metal Constructions ADVAL is a member of BCC /Bulgarian Construction Chamber/ BAGTC /Bulgarian Association for Geotechnical and Tunnel Construction/ ITA- AITES STUVA eV
Products Tunneling Making of tunnels is crucial for the contemporary road construction as in urban areas /metro tunnels, underground parkings, underpasses/ and also the making of highway and railway tunnels.
Products Drilling and grouting works Drilling and grouting works for construction of dam walls; Consolidation and concreting of weak soils with unstable geology; Grouting works in tunnels; Drilling and grouting works for execution of pipe anchors.
Products Metal constructions Producing of all kind reinforcement for pile constructions and diaphragm wall constructions; Making of all kind metal structures such as road overhead passing, metal warehouses, metal frames for bridges, etc.;
Products Diaphragm walls and pile constructions Confining of underground spaces in dense populated urban areas – underground parks, bank and office safety vaults, metro stations, metro tunnels; Reinforcement of landslides in close proximity of roads, rivers, in populate and also rural unsettled areas; Foundations for buildings and heavy installations (bridges, roads, reservoirs, water supply network and electric transmission network) especially by complex geological conditions – disjoined soils, soils with high water content and in swamp areas.
Products Sheet retaining walls The sheet walls could be pressed, driven by vibrations or by hammering into the ground in compliance with the local ground characteristics. Moreover, they could be installed as dense wall, in excavated in the ground diaphragm panels. Since sheet walls are executed as barriers, which are water impermeable, it is possible at their joining with cohesive soil layer or artificial dense bottom, the need of ground water table lowering on big areas to drop out.
Products Sheet retaining walls The sheet retaining walls are suitable for excavation pit strengthening, terrains strengthening, Insulation against pressuring water, temporary reinforcement facilities.
Products Mass excavation and disposal Excavation and disposal of earth, rocks and unnecessary materials that should be removed and transported from the construction sites;
Products Production and transportation of concrete and shotcrete Producing of all kind of concrete and shotcrete for diaphragm wall constructions, pile constructions, tunnel constructions, foundation slabs, road constructions, residential constructions, etc.
Products FRANKIPILE® NG /New Generation/ The FRANKIPILE® NG can be used in a wide range of foundation soil conditions as a deep foundation element for all types of constructions such as bridges, roads, tunnels, industrial and office buildings, dock bases, crane ways, wind power plants and many more. It offers particular advantages in places where high loads have to be transferred or where good, load-bearing foundation soil occurs very deep down in the ground.
