invatec was founded in 1997. Always on the look for new and particularly for better approaches, the traditional concrete cable duct installations along railroad tracks were revolutionised right at the very beginning by the development of practical and easy-to-handle plastic cable ducts. The creative solutions elaborated by our skilled and highly specialised team of invatec experts have always enhanced efficiency, be it for special solutions made of steel or for signal foundations and gravel mounting plates.
Unique for invatec are our dedicated »Inno Teams«, prepared to elaborate new approaches together with our clients. Quite frequently it only takes marginal optimisations or special solutions to make the working life easier and to pave the road to success.
»Together« is the key word for success, since there is no one else who will know your company better than yourself. What we can do is to take a neutral look "from the outside", which frequently helps to come up with new opportunities. From an initial consultation on to the possible realisation of innovations and further on to their integration into your processes - a competent consultant will always be right at your side. Only those who dare to continuously and consistently question, optimise and retune everything will ultimately be capable of working successfully for the long term.
We intend to positively surprise you in every respect! Our continuous further developments, product trainings with certification, our comprehensive services offered, and our just-in-time deliveries make us a business partner who truly understands you.
Training and consulting – Leading by knowledge
Our services – More reliability for you
Our logistics center – Processing on schedule
The protection frame offers a proper enclosure for the screwed fastening especially for light poles mounted on the TECDOWN foundation system. The anti-slip treated cover allows the acces to the screws for proper service and maintenance. It is a simple and lightweight alternative to heavy and bulky concrete solutions.
Cables are the connecting arteries of our modern times. Anyone who wishes to move either energy or information has only one choice - cables.
invatec is a renowned enterprise also in the sector of plastics engineering and has been developing and manufacturing cable ducts made of synthetic materials since 1997. Invatec’s innovative cable ducts demonstrate their advantages already during transport and installation or when it comes to the entire logistics process.
A reliable supply of electricity and data transmission are the basic prerequisites for a smooth operation of state-of-the-art industrial facilities and infrastructures. Cables are sensitive lifelines of our economy, which need to be protected comprehensively: By the tried-and-proven and at the same time pioneer VARIO TEC+ cable duct system for ground installation. The Federal Railway Authority has certified the VARIO TEC+ synthetic cable ducts of sizes 1 and 2 for ground mounting.
Certification numbers: 1221/1110/21AZ2/0045/8 and 1221/1110/21AZ2/0024/8
True professionals have cooperated in the development of the VARIO TEC+: Civil engineering practitioners with many years of experience in the construction of cable ducts and engineers equipped with state-of-the-art virtual design systems.
The result: a combination of quality, profitability, environmental compatibility and outstanding value for money that establishes a new benchmark.VARIO TEC+ combines a solid design with a low weight and excellent profitability. Areas of application are e.g. railroad facilities, airports, power stations and industrial facilities.

Load bearing capacity
|The complete cable duct is capable of withstanding a load of approx. 760 kN/m without breaking. The lid is designed to handle the following loads:
approx. 433 kN/m at a temperature of -35º C
approx. 527 kN/m at a temperature of +80º C
|Thermal properties||Permanent dimensional stability between -30 °C and +85 °C|
|Thermal expansion coefficient||1.2 x 10-4 cm per °C.
The lid is equipped with expansion joints in longitudinal and transverse direction in order to reliably prevent any expansion caused by heat.
|Behavior in fire||Fire protection category K1 acc. to DIN Standard 53438 part 2|
Heavy and bulky concrete slabs (weighing approx. 200 pounds each) have so far generally been employed when constructing service roads in the framework of civil engineering projects of world wide rail industries. Since their installation, however, presents various disadvantages, a novel alternative to gravel mounting plates made of concrete was developed.
invatec’s gravel mounting plates consist of panels (2,000 x 250 mm) that are made of glass fibre reinforced plastic (GFRP or GRP). Simple installation together with a low weight (only about 20 lbs per panel) are their essential benefits. HEB 100 double-T steel profiles are used as supports into which the GRP panels are inserted.
The performance portfolio of invatec also includes innovative signal foundations. Signals are crucial control elements in railway and road traffic. They are the prerequisite for the optimal safety of traffic users. Standard masts with and without gantries are employed for civil engineering projects of DB AG. A solid foundation for the signal is essential here.
Our »TECDOWN« piling tube foundation is approved for all signals used by and all route categories of DB AG and is equally suitable for maintenance as well as new construction projects.
This system for signal foundations has reached its final development stage after a development process of about two years and the production of various prototypes used in facilities of DB Netz AG. The signal foundation "TECDOWN" is protected for the inventor by patent and trademarks. After undergoing comprehensive tests and completion of the certification process with the Federal Railway Authority, this signal foundation has reached commercial maturity.
The adapter sports a corrosion protection acc. to ZTV-ING, Part 4, with hot-dip galvanization acc. to DIN EN ISO 1461 as well as an intermediate and top coating acc. to the TL/TP-KOR for steel structures, Page.87. For process-related reasons the contact area with the mast base features only a hot-dip galvanization. If specific requirements apply regarding corrosion protection (for example traction) the adapter may be equipped with an additional protective isolation coating. Loads may be applied after curing of the casting as soon as 60 % of the standard strength of a C25/30 has been reached, provided that adapters are used.
The production of foundations for driven piles makes comprehensive interventions in the pressure area of the tracks unnecessary. In addition to the effect that the existing soil structure is hardly affected, the negative effects on the operation may also be reduced on account of the quicker construction process – more than 75 % in comparison with individual foundations made of prefabricated concrete elements. Please note that this reduction of the negative effect on the operation also includes the considerable passive construction costs such as for example securing operations, deactivation and earthing of overhead traction lines, construction supervision, preparation and implementation of the necessary paperwork as well as expenditures for a lack of route availability (railroad traffic speed reductions, detours, alternative transport etc.).
If heavy loads or high temperatures need to be catered for, steel is the optimal material for the job. Solutions are developed for the most different applications, tailored to the respective requirements encountered on site. We exclusively manufacture small and medium volumes. Specific tasks may be catered for individually – with a volume of as low as one. We manufacture top quality products that are precisely tailored to your individual needs. We deliver at the right time and to the right place – not to mention: at an excellent value-for-money.
Our »Inno-Teams« are prepared to face new challenges. They meticulously work to come up with new solutions and develop products for unusual applications together with you. Understanding, perspective, flexibility, vigour, and passion are our qualities – permanently employed to elaborate the best results for our client: For YOU.
