Underground pipe jacking is a construction method that has been tried and tested for years, and that has well-known, undisputed advantages, especially in residential areas. At the same time this process makes particularly high demands on the pipe due to the extreme jacking loads applied during installation. The pipe must sustain these enormous forces and transfer them evenly and in a controlled manner, which requires perfect dimensional accuracy. Meyer-POLYCRETE has specialized in this application area. Our POLYCRETE® jacking pipes have proven their usefulness in this environment over decades.

Creating the best products from high quality materials. We manufacture POLYCRETE® pipes exclusively through casting, in accordance with this guiding principle. Only this way can the recipes be tailored ideally to the application and homogenous mixtures be prepared. That is because the uniform, thorough mixing process and the mixing ratio of the raw materials we use determine the long term usage characteristics of the pipes.
The direct contact of the material and the casting formwork guarantees continuous smooth and high quality surfaces over the complete length of the pipe. These surfaces are then finished with an additional coating.

Egg profile pipes are ideally suited for the construction of mixed water sewers. Less deposited material due to the higher sweeping forces in dry weather conditions, high capacity reserve for heavy rainfall events, smaller trench width and load-bearing width as well as easier cleaning and walkability are some of their advantages.

Kite profile pipes represent an improvement of flow-optimized pipe cross sections. Through the combination of a narrow dry weather channel and a high-capacity overflow space POLYCRETE® kite profile pipes are particularly well suited for use in mixed water sewers with extreme fluctuations in waste water quantities. 

Strong enough for high dynamic loads, stable shape, suitable for high-pressure cleaning and particularly impact resistant. The POLYCRETE® manhole meets all challenges for a sewer system during installation and operation - as required in practical applications. And at the same time it has the necessary weight for the desired bouyancy protection.

The formation of sulphuric acid by thiobacillus in waste water systems cannot always be avoided by planning. Besides the direct introduction of waste water containing sulphides, unfavourable waste water conditions such as long waste water dwelling times or insufficient oxygen supply can lead to sulphide problems. Due to the controlling framework parameters this often starts from the pump stations.

For larger connection diameters, various different inlets and outlets and particular technical requirements the compact system manhole elements are often not sufficient. In such cases it is recommended to install POLYCRETE® shaft structures that are individually planned, designed and manufactured in close cooperation with the user for specific dimensions, loads and construction site conditions.

POLYCRETE prefabricated shafts are particularly cost-efficient when installed as sink shafts where the ground water level is high. The details of these sink shafts are tailored for their intended function and installation position, also taking buoyancy protection into account. With their functions as intermediate and reception shafts they are an environmentally friendly and economical solution for micro-tunnelling. As a manufacturer with a comprehensive range of jacking technology we plan, design and produce intermediate and reception shafts in the dimensions required by the jacking machinery. Of course POLYCRETE sink shafts can be furnished for different purposes, e.g. as pump stations, valve shafts or measuring stations.

For decades, polymer concrete, also known as “filled reactive resin moulding material” has proven to be a construction material of high chemical and mechanical resistance in industry and pipeline construction. Due to efficient production processes, high-performance formulas, high-quality components and technically mature pipe connections, meyer-POLYCRETE has succeeded in launching polymer concrete with the name POLYCRETE® as multifunctional, efficient, corrosion-resistant and dimensionally stable material in the public sewage sector.
