SONAR was established in 1977 by Muzaffer Çevik, with specialization in "drilling" and "engineering geology", which was followed by the establishment of "grouting" and "water well drilling" departments. In 1993, "geotechnical engineering" branch of civil engineering discipline became the main field of activity. With 33 years of experience, SONAR has become a national leader in the field of geotechnical engineering.

SONAR is currently engaged in contracting activities with a geographical emphasis on Turkey, Middle East and Eurasian countries.

Within each of our main activities, SONAR offers a range of services and capabilities, ensuring the optimum technical solutions to all kinds of geotechnical problems. We recognize that meeting the needs of our clients involves not only technically effective solution but it also means providing permanent, economic and safe solution in the feasible shortest time.

Deep Foundations are structural elements designed for the transfer of heavy

loads through weaker soil layers to a suitable bearing layer of soil or rock.

SONAR has been working in the field of deep foundations

since 1993, completing many critical deep foundation

projects for viaducts, bridges, dams, retaining walls

and highrise buildings.

There are various types of deep foundations which are

specialized for application to different soil and loading

conditions.

- Bored Pile

- Barrette Pile

- CFA Pile

- Micro Pile

Especially in urban environments vertical sidewalls are preferred, requiring a suitable system which will

restrain the lateral soil and groundwater forces and also stop the groundwater from entering into

the excavation from side walls.

• Bored Pile Walls

• Diaphragm Walls

• Micro Pile Walls

• Sheet Pile Walls

• Jet-Grout Walls

• Reinforced Concrete Walls

• Ground Anchors

• Soil Nails / Rock Bolts Combination of all of the systems above

In this special method, which is executed by

Diaphragm Walls, the retaining walls are

designed as the basement walls of the structure.

Excavation is done level by level after

constructing the structural slabs of the respective

floor.

Time Saving Advantages: Basement & Upper floor construction may continue at the same time! Climatic Conditions are eliminated in lower floors.

Money Saving Advantages: Retaining wall becomes the permanent walls of the main structure. Anchors are not necessary, slabs functions as struts.

1 – Diaphragm Wall Production 2 – Bored Pile or Barette Pile Production to act as basement columns

3 – Construction of Ground Level Slab 4 – First Basement Floor Excavation and construction of slab.

5 – The Construction of Raft Foundation.

In certain soil conditions, it might be more economical to improve the

engineering properties of weak soil, instead of bypassing it with deep

foundations.

Depending on the soil type and application Ground Improvement may;

Increase Bearing Capacity

Increase Lateral Capacity

Reduce Settlement

Mitigate Liquefaction Potential

Improve & Maintain Impermeability


Ground Improvement Methods applied by SONAR are;

Grouting

Jet Grouting

Vibro Stone Columns

Vibrocompaction

Wickdrain

Well Point

Pre-loading

Dynamic Compaction
