Industrial Construction with Safety and System
As a specialist in industrial construction, we deliver all services from a single source: safe, forward thinking and with the aim of integrating projects seamlessly into our clients’ operational processes. Our focus is on projects in sensitive industrial environments such as refineries, chemical parks, power plants or major logistics sites, as well as in the energy sector.

Building on Substance
We create the foundation for every construction project. With a modern fleet of equipment and experienced teams, we carry out all civil engineering works precisely, safely and on schedule. Even complex tasks or challenging ground conditions are mastered through solid expertise and well planned execution.
Our services include:
- Site grading and earthworks
- Excavations, foundations and backfilling
- Groundwater control and lowering
- Soil stabilisation and soil replacement
- Works in contaminated areas in accordance with DGUV Rule 101 004

Precision and Quality
We install pipelines made from a variety of materials and in different dimensions - for both gravity and pressurised systems. Our services cover new construction as well as rehabilitation.
Our specialists hold extensive qualifications in plastics welding and sewer construction, enabling us to create durable, safe connections - whether for drainage, supply systems or technical media.
Our services include:
- Installation of gravity and pressure pipelines made of PVC, PE HD, PP, concrete and reinforced concrete
- New construction and rehabilitation of sewer systems
- Plastics welding in accordance with DVS 2212 and 2213
- Construction in contaminated or sensitive areas

Reliable in Brownfield Environments
To ensure the smooth operation of our clients’ production facilities, we safeguard the structural integrity of large industrial plants over the long term. On the basis of framework agreements, we undertake continuous maintenance and further development of infrastructure — from minor repairs to extensive structural modifications.
The focus lies on work carried out during ongoing operations, the so called brownfield environment. Close and cooperative coordination with our clients ensures that all construction activities are optimally integrated into their operational processes.
Our services include:
- Ongoing maintenance of industrial structures and surfaces
- Expansion, modification and refurbishment of existing facilities
- New construction within active industrial plants
- Long term support under framework agreements

Stability in Perfection
High demands for quality, safety and environmental protection are part of our daily routine. We deliver complex concrete and structural engineering works, even under challenging conditions and restricted space.
Through careful planning and efficient formwork concepts, we ensure precise and economical execution — resulting in high quality structures that meet the highest technical and scheduling requirements.
Our services include:
- New construction and refurbishment of concrete and reinforced concrete structures
- Construction of technical structures such as foundations, shafts or retaining structures
- Special solutions for complex construction conditions or difficult ground situations
- Planning and execution of efficient formwork and reinforcement concepts

Energy efficient, Sustainable and Digitally Planned
Our extensive experience in technical building services forms the basis for tailored solutions that combine functionality, energy efficiency and economic viability. We take on complete planning on request or further optimise existing concepts.
Through close coordination between planning and execution, we minimise interfaces and ensure that all systems work together seamlessly — from energy supply to ventilation technology.
Our services include:
- Planning and execution of technical building services
- Optimisation of existing systems and installations
- Integration of energy efficiency and sustainability concepts
- Support through to commissioning

Durable and High performance
Mainka paves the way. Whether roads, storage areas or parking spaces — we construct all traffic surfaces required for a functioning infrastructure. Our asphalt works are carried out even under challenging conditions, using pavers or by hand in hard to access areas.
In addition to classic asphalt solutions, we offer semi rigid pavement systems. Here, the asphalt support layer is filled with a special mortar, creating extremely robust surfaces that can, upon request, also be constructed as sealed surfaces compliant with the German Water Resources Act (WHG).
Semi rigid surfaces provide short curing times and high load bearing capacity, making them ideal for container storage areas or tanker loading zones.
Our services include:
- Asphalt, concrete and paving surfaces for roads, industrial and logistics areas
- Construction of WHG compliant sealed surfaces
- Semi rigid pavement systems using special mortar
- Rehabilitation and repair of existing traffic areas

Industrial Construction - fully thought through
Mainka stands for complete industrial construction projects from a single source. We support our clients throughout the entire construction process as a central point of contact. From planning and coordination of all trades to turnkey handover, we manage all tasks reliably and efficiently.
Our strengths lie in schedule and cost certainty as well as close coordination with everyone involved. The result: buildings that are convincing both technically and economically.
Our services include:
- Planning and coordination of all trades
- Site supervision through to turnkey handover
- On schedule and on budget project execution
- Documentation and support after completion
