The MEMPEX company formation and development history dates back to the early 1990th, the difficult years of Perestroika.
Already at the beginning of our way, we understood that, in market economy, only implementation and application of new technologies will provide opportunities to enter the construction market and to develop our activities further.
With our steady commitment to the creative search for the company development areas, we paid our attention to the problems affecting the cities during the construction of above-ground pipelines. In those times, with highly dense layout of urban buildings, Minsk was virtually choked when these works were in progress. We studied the experience of foreign countries and purchased several small machines made by Tracto-Technik GmbH (Germany).
In 1996 MEMPEX was the first in the Republic of Belarus to apply the trenchless technologies for replacement of worn sewerage pipes by new ones at a construction facility in Minsk. The dynamic destruction of old pipes and high-density polyethylene pipe pulling, with pipe string length up to 120 m, was used to replace the sewerage pipeline, Ø160 mm, by another pipeline, Ø225 mm.
Due to the trenchless technology, large amounts of money were saved by the city; also, surface buildings and road pavements were preserved.
With the positive experience gained in construction, and with realistic assessments of conditions existing in the construction industry (expected scopes of construction and repair of underground utility systems), we began to consider the need to make own equipment.
Already at the initial stage of implementation of our plans for the development of equipment to be manufactured by our company itself, we decided to reject the common approaches, such as copying, cloning or low price priority, the approaches that, at our opinion until now, result in dead end.
In this regard, the MEMPEX management adopted a concept specifying the company’s principal approach to the equipment development. It provides for the integrated approach to the equipment functionality. In other words, the equipment operated by customers must address not only the specific small-scale problems but the whole set of tasks in application of trenchless technology for construction or repair of utility systems.
In 2001, the MNB-50 equipment complex was designed and its manufacturing was launched. The feature of this new development of our company is its ability to carry out the range of works, both to replace old pipes and to lay new ones.
In 2005 – 2006, the MNB-125 equipment complex was designed and implemented for manufacturing. This complex can be used to replace pipelines made of various materials (such as ceramics, cast iron, steel etc.), with the existing passage expansion up to Ø600 mm, or to carry out pipe-jacking (make pipe subways) and lay pipes, up to 500 mm, within lengths up to 150 running meters.
In 2005, the unique formwork, OR-1.5, was designed and implemented for manufacturing. This collapsible movable formwork shall be used for trenchless works with the protected MNB-50 equipment at depth up to 5 m.
In 2011, the smaller-sized version of the equipment complex, UNB-20, was designed and implemented for manufacturing. It can be used to make underground passes, both from the surface or from a small pit.
2014 is the year of comissioning of a unique machine for trenchless replacement of pipelines ST-40. The uniqueness of this machine is that the modularity of its assembly and low weight allow it to be lowered into the well directly through the manhole with diameter of 600 mm, and to perform quick installation of the unit, while during further work the operator can be located outside the well and control the entire process from the surface.
In 2015: a fundamentally new equipment has appeared in our product line: a directional auger drilling machine MNBS-600. The drilling is carried out under the control of a laser navigation system, providing a consistent slope for straight-line communications.
2016: we move forward. A multifunctional machine MNBL-70 is developed. The machine allows both straight-line drilling with a consistent slope under the control of a laser guidance system, and curved drilling when using a radio location system.
2018: two new ultra-compact and multifunctional machines are created: UM-20 and UM-32. Both machines are light-weight, made of high-strength aluminum alloy, and both allow maximum maneuverability in urban environment.
In 2021: two new machines are to be commissioned: MNBS-1200 with maximum pipeline diameter of 1200 mm and the pushing force up to 250 tons, as well as MNBS-400, a smaller version of the latter.
