ZUBLIN CONSTRUCTION L.L.C
About us

Züblin was founded in Switzerland in 1986. We specializes in the development and maintenance of presence and movement detectors, sensors and LED lights. Between 1992 and 1997, subsidiary companies were estabilished in France, Germany and Austria. Our products have become the most energy-efficient lighting systems in Europe. At the start of 2014 Züblin expanded once more, this time in Poland. Today, the Züblin Group has a turnover of over 20 million euros and employs around 70 people.

SERVICES

DIAPHRAGM WALLS

Diaphragm Walls Of Various Kinds Are Used To Secure Deep Excavation Pits. For Instance We Use Them In Combination With Other Measures As Solid Retaining Walls, As Foundation Elements For Bearing Loads Or As Sealing Against Groundwater. Diaphragm Walls Can Be Installed Very Close To Existing Buildings And Provide Good Water-Tightness Even In The Case Of Very High Groundwater Levels.

Every Year, We Use This Technique For Several Tens Of Thousands Of Square Metres. Typical Customers Are Investors In Building Plots In Urban Neighbourhoods With Difficult Subsoil Conditions, Landfill Operators And Public Authorities For Major Infrastructure Projects.

Construction Methods:

Reinforced Concrete Diaphragm Wall

Single-Phase Cut-Off Wall

Two-Component Cut-Off Wall

Thin Slurry Wall

Barrettes.

PILES

We Have The Technical Equipment For All Manufacturing Methods, From The Largest Bored Piles To Micro-Piles. Where Subsoil Conditions Allow, Driven Piles May Also Be Provided As A Fast And Thus More Cost-Efficient Alternative For The Founding Of The Heaviest Loads. We Also Have Special Equipment For, And Experience With, Foundation Improvement Underneath Existing Buildings And In Confined Height Locations.

Secant Piling Can Be Used To Create A Complete Bored-Pile Wall With Large Diameter Bored Piles To Serve As An Almost Watertight And Low-Deformation Retaining Wall. With Our Test Equipment, We Are Able To Check Test Piles Prior To The Start Of The Construction Measures To Economically Optimise The Foundation Design For The Customer.

Construction Methods:

Large Diameter Bored Piles (Bored, Grabbed)

Micro-Piles

Vibro-Injection Piles, Grouted Piles

Augered Cast-In-Place Piles (Continuous Flight Auger)

Driven Piles

Pile Tests

Stone Columns.

RETAINING WALLS

Where Lower Demands Are Made On Water Tightness Or Deformation Behaviour, We Recommend Our Other Retaining Wall Techniques Instead Of Diaphragm Walls And Bored-Pile Walls:

Sheet Pile Wall

Sheet Pile Walls Consist Of Cramped Steel Sheet Piles Which Can Be Placed With Unrivalled Speed In Soils Into Which Piles Can Be Driven Easily. Moreover, Where The Sheet Piles Can Be Removed And Reused On Completion Of The Work, This Technique Is An Attractively Cost-Efficient Solution. Reinforced By Pipes And Beams, Sheet Pile Walls Can Transfer Extreme Loads. They Are Used Mainly In Hydraulic Engineering Projects.

Soldier Pile Wall

The Soldier Pile Wall Is A Traditional Construction Method. Today, Steel Beams Previously Installed Into Bore Holes With A Low-Vibration Method Are Laid Bare As Excavation Work Progresses And The Spaces Between Them Are Sheeted With Squared Timber Or Reinforced Shotcrete.

Shotcrete With Soil Nails

We Preferably Secure Steep Slopes By Means Of Soil Nailing Using Steel Bars Mortared In Drilled Holes. The Steel Reinforces The Soil Making It Behave Like A Monolithic Block. We Seal The Bared Slope Surface Step By Step With A Reinforced Shotcrete Skin.

ELEMENT WALLS

Element Walls May Also Be Used To Master Steep Slopes. They Consist Of Prestressed Steel Tension Members Anchored In Deeper Ground To Restrain The Concrete Anchor Plates Which Retain The Surface Of The Slope.

Construction Methods:

Bored-Pile Walls

Reinforced Concrete Diaphragm Walls

Sheet Pile Walls

Soldier Pile Walls

Shotcrete With Soil Nails

Element Walls

Combi Walls

INJECTION PROCESSES

The Subsoil Can Be Improved By Injecting Various Environmentally Compatible Substances. The Objectives May Be Very Different: Increase Subsoil Stability, E.G. On Sliding Slopes Or To Underpin Neighbouring Buildings, Compensate Weighing Down, I.E. Compensation Of Detrimental Settlement Caused By The Placement Of Additional Volume Into The Subsoil Or Reduce Water Permeability, E.G. For Horizontal Sealing Underneath The Base Of The Excavation.

Extensive And Lengthy Water- Right Proceedings As Well As High Extraction And Discharge Fees May Be Avoided Especially In The Latter Case If The Amount Of Groundwater Flowing Into The Excavation Pit Is Reduced To A Minimum. As The Leading Company In This Field, We Also Support The Creation Of Standards For Special Grouting Methods In The Context Of The European Standardisation Efforts.

Züblin Has Developed The SOFIA® Software To Control Compensation Grouting. The Software’s Control Loop Is Fed With The Information From The Water Level Measuring System And The Data Of The Grouting Carried Out. That Information Is Processed Automatically By The Software, Visualised And Archived In A Database. The Database Structure Enables The Site Supervisors To Provide Standardised And Auditable Reports On The Grouting Work To The Client In Tabular Or Graphical Form.

Construction Methods:

Jet-Grouting Method (HDI)

Low-Pressure Injection

Plastic Gel Injection

Cement And Fine Cement Grouting

Compensation Grouting

Liquid Plastic Grouting (Polyamide).

GROUND ANCHORS

Ground Anchors Are Prestressed Tension Members Made Of Steel Strand Or Bar Installed Into Mortared Boreholes. They Are Used As Temporary Or Permanent Aids To Transfer High Tensile Forces Into The Ground And In Pit Retaining Walls, To Protect Buildings Against Groundwater Uplift Forces, To Secure Slopes Or To Transfer The Reaction Forces During Pile Test Loading.

Our Range Of Services Includes The Securing Of Masonry Dams By Means Of High-Load Anchors As Well As High-Pressure Grouted Rod Anchors.

Construction Methods:

Temporary Anchors

Permanent Anchors

Strand Anchors

Uplift Restraint Anchors

Shotcrete With Soil Nails

Rod Anchors.

SPECIALIST FIELD

In Particular Cases, Special Construction Methods Are Used For Which We Are Well Prepared With Our Qualified Personnel And State-Of-The Art Equipment.

Directional Horizontal Drilling Can Be Used To Establish Connections Over Long Distances Without Affecting The Land Surface Above. Directional Horizontal Drilling Is Used Where Buildings, Bodies Of Water Or Special Facilities Such As Nature Reserves, Airports Or Railway Tracks Have To Be Passed Under. This Avoids To A Large Extent The Otherwise Necessary Interference And Associated Costs.

In The Context Of The Preservation Of Historical Monuments, Translocation Means The Documented Dismantling And Subsequent Restoration Of A Historical Building In Another Place As True To The Original As Possible. This Is Done Primarily Where A Cultural Monument Is In The Way Of A Construction Project. We Have Developed An Even More Gentle Solution To This Problem. We Move The Complete Building To Its New Location On Special Sliding Tracks.

We Even Offer Complicated Movements Of Tunnels Under Water As An All-In Service. This Greatly Reduces Impairment Of Traffic On Inland Navigation Routes.

Construction Methods:

Horizontal Drilling

Movement Of Buildings, Tunnels Etc.

SUBSOIL FREEZING

The Subsoil Is Frozen To Prevent Groundwater From Entering The Excavation Pit. To Do This, Pipe Coils Are Installed In The Ground In Which A Coolant Circulates. The Result: The Water In The Ground Freezes.

The Solidifying And Sealing Effect Of The Icing Is Used E.G. For Cross Passages In Tunnel Construction Under Water And In The Case Of Remediaton To Bind Highly Volatile Hazardous Substances In The Ground.

DEEP DRILLING

In Times Of Increasing Energy Costs And Ever Scarcer Resources, Geothermal Energy Is Becoming Ever More Important. Furthermore, The Enormous Potential Of Geothermal Energy For Heating And Energy Storage Is Constantly Increased By Intensive Research And Development.

In The Spirit Of A Turn Key Approach Our Business Activities Include Planning, Permission And Execution Of Deep Drilling Works For Hydrothermal Direct Use. Another Focus Of Our Activities Is In The Field Of Indirect Geothermal Energy Utilisation Via Medium Deep Borehole Heat Exchangers For Heating And/Or Seasonal Heat Storage. With Our Deep Drilling Equipment, We Can Execute Exploratory Drilling For Reservoirs Down To 1,500 Metres And Geothermal Development Drilling Down To 1,000 Metres.
