Excavation, hauling and backfilling

We lay the foundation

Thanks to our state-of-the-art technology, efficient planning and maximum precision, we ensure smooth processes and stable foundations. Whether it’s a residential, commercial or industrial project, we move earth so that your visions become reality.

Services

  • Excavation of construction pits of all kinds
  • Backfilling of working spaces, compaction work
  • Earthworks and hauling at construction sites
  • Grading and structural consolidation
  • Excavation of sewer and drainage ditches
  • Excavation of foundations

Sewer construction

It will surely flow

Precise sewer construction is the first step in reliable wastewater disposal. We lay, inspect and maintain sewers and sewage pipes of all sizes and materials – from handling building laterals to large-scale projects. Whether for separator, infiltration or small sewage treatment plants, by using innovative shoring methods such as sheet pile, soldier pile or spray concrete shoring, we ensure safe and durable solutions. We create sustainable infrastructures for today and tomorrow using modern drilling techniques, from thrust boring to vertical and horizontal directional drilling.

#Specializations 

Deep construction pits / work on wastewater systems during ongoing operations / inner-city construction measures / lowering groundwater levels / implementation planning / logistics concepts

Services

  • Open cut construction
  • Trenchless construction
  • Shoring boxes
  • Slide rail shoring
  • Sheet piling
  • Berlin-type pit lining

Asphalt construction, paving and slabs

Road construction at its best

We build roads that last. We ensure durable and resilient traffic routes, from new construction to repair and maintenance. Our portfolio also includes curb edging, design work and water-bound path surfaces. Thanks to our in-house asphalt construction crews, we can complete projects quickly and efficiently. We focus on digital precision and maximum efficiency with state-of-the-art 3D machine control – setting standards for road construction.

Services

  • Edging

    (flush curbs / raised curbs / planting and traffic islands / gutter systems / square edgings / wall panels)
     

  • Surface work

    (courtyard areas / road design / industrial sites / hall floors)

Small-area asphalting

Precise asphalting for every surface

We supply first-class asphalt surfacing for roads, paths and parking lots in small and medium-sized areas of road and industrial construction. Our state-of-the-art machinery and experienced team ensure projects are completed in an economical, timely and high-quality manner. Thanks to our smart processes and maximum efficiency, we provide precise small-area asphalting that delivers on its promises.

#Specializations

Road restoration / asphalt restoration / quality construction / joint and crack repair / road damage repair / footpaths / cycle tracks / access roads / cable trenches / line trenches

Services

  • Base courses
  • Binder courses
  • Surface courses
  • Ancillary services such as excavation, milling, cutting, joint tapes and joint sealing

Development of building areas, commercial areas and industrial areas

Infrastructure expansion the TERRAS way

Wherever new residential, commercial and industrial areas are created, we get the important connections underway. We make sure that everything runs smoothly, from precise earthworks and sophisticated drainage systems to laying sewer and supply lines. We create the foundation for high-performance, sustainable infrastructure through our combination of experience, efficiency and technology.

Services

  • Laying drinking-water pipes
  • Laying pressure lines
  • Installing drainage channels
  • Laying communication and street-lighting cables
  • Laying underground supply cables
  • Stormwater drainage channels
  • Stormwater retention basins and stormwater overflow basins

Structures for water supply and disposal

Precision meets engineering

We design and build functional engineering structures for water supply and wastewater disposal. Thanks to our in-depth expertise and strong network of specialized engineering firms, we are able to provide support for technical planning and implement projects efficiently and on schedule. We supply everything from a single source, from excavation and shoring to construction, final surface design and technical equipment.

Services

  • Stormwater retention basin
  • Storage basin
  • New construction of wastewater treatment plants
  • Wastewater treatment plant conversions
  • Open and covered channels
  • Special shaft structures

Horizontal directional drilling at the highest level

Efficient, fast, trenchless

We use state-of-the-art horizontal directional drilling technology to lay supply lines below roads, railways and waterways. This method eliminates the need for costly earthworks and traffic obstructions. This trenchless method is more efficient, conserves resources and protects existing infrastructure. Electricity, gas or telecommunications – we bring lines safely to their destination without harming the environment or the flow of traffic.

Advantages

  • Economical and ecological
  • Minimal civil engineering work
  • Preservation of the areas above (e.g., traffic areas, etc.)

Demolition work and rubble disposal

Systematic demolition, sustainable disposal

We make room for new things in a professional, safe and sustainable way. We use state-of-the-art machinery to dismantle buildings, industrial plants and asphalt and concrete surfaces. But demolition is just the beginning – we professionally sort, recycle and dispose of rubble to conserve valuable resources and protect the environment.

Services

  • Demolition of structures such as buildings and industrial facilities
  • Professional sorting and disposal of all construction materials
  • Asphalt and concrete surface removal

Gallery construction

Maximum flexibility underground

Gallery construction is a reliable alternative when conventional pipe jacking reaches its limits. Using precise static calculations and custom-made timber or steel structures – flexible or rigid – we create underground structures that meet the highest standards. Precision and experience make the difference.

Dimensions

Excavation cross-sections

Up to approx. 10 m²
