optemBLOK – reinforced soil retaining walls

The optemBLOK retaining wall system is designed primarily for infrastructure construction, but also for individual clients. The entire process is in our hands – we take care of the PRELIMINARY & DETAILED design, pricing and delivery of reinforced soil retaining walls. In our Geotechnical Laboratory we create concepts, construction, detailed, technological and replacement designs, always adapting them to the needs of the client.

We carry out masonry projects in both active and passive systems. We have also developed a proprietary product of masonry crowning in the form of an L-type or T-type cap. Compared to the classic monolithic finial, with a cornice board, our system solutions require much less labor and financial resources.

One of the most interesting realizations is the construction of the Oswiecim bypass, where we designed and delivered retaining walls up to 14.7 meters high – for more details, see the article in the “Download” tab.

Walls made of optemBLOK reinforced soil – advantages

  • Quick and simple installation

    The optemBLOK system is characterized by easy and fast installation, thanks to repetitive work that can be performed without skilled CONSTRUCTION OPERATIVES– preliminary training is enough. The blocks are light enough to be laid by hand, reducing the need for heavy equipment and thus reducing construction costs.

    Backfilling and compaction of the reinforced soil is done with light equipment, and the precast elements can be loaded immediately after installation, which is impossible with monolithic masonry.

  • Flexibility in design

    The construction of reinforced soil retaining walls is based on a simple installation scheme with considerable repetition, which contributes to high efficiency and speed of work. However, it is necessary to follow the rules of installation and the guidelines contained in the Reinforced Soil Retaining Wall Construction Manual, available in the ‘For Designers’ tab.

    It is worth noting that the system offers great flexibility in shaping the geometry of the walls, both vertically and horizontally. The small dimensions of the blocks make it possible to create precise arches and curves, and thanks to special openings, it is possible to build vertical sloping walls, as well as those that deviate from the vertical.

    The most commonly used backfill is medium sand with a friction angle of min =34o ( fi = 34 degrees). Want to build a different type of backfill than the commonly used one? Contact us and we will certainly find a solution together.

  • Effective drainage system and aesthetics

    The proper functioning of a retaining wall depends on an effective drainage system. Channels in the blocks are filled with drainage aggregate to effectively drain water from the embankment. This prevents moisture from seeping through the blocks, causing dampness, staining or efflorescence, and minimizes hydrostatic pressure on the wall. Water from the space behind the walls is drained into a drainage pipe that directs it away from the structure.

    Walls from the optemBLOK system have an aesthetic texture achieved by splitting the blocks, and their production generates lower CO2 emissions compared to traditional reinforced concrete masonry. Adherence to technological recommendations provides a durable, aesthetically pleasing and economical solution in the construction of reinforced soil retaining walls.

    Our precast wall finial in the form of a precast T- or L-type cap stabilizes the structure and allows for the solid installation of the balustrade.

What does the optemBLOK system consist of?

Vibro-pressed small-sized blocks
Precast blocks perform the function of facing, protect the object from surface erosion and give the structure an aesthetic appearance.
Geonets for soil reinforcement
The optemBLOK system uses polyester geogrids for soil reinforcement. Their task is to reinforce the soil, helping to transfer the stresses that arise under dead and dead weight, which the soil itself is unable to transfer. By working with the backfilled soil, the geonets ensure the stability of the entire structure.
Connectors
Plastic fasteners provide additional stabilization of the entire optemBLOK system. They are placed in special holes in the retaining wall blocks, which allows precise positioning of successive layers of blocks.
Supplementary elements for the optemBLOK system
The optemBLOK system also includes

  • Aesthetic corner blocks
  • L-type or T-type precast caps:
    • ○ T-shaped caps – a concrete precast cornice, including a monolithic finial. Balustrades, energy barriers or noise barriers can be mounted to the parapet when the reinforced concrete part of the parapet is properly designed.
    • ○ L-shaped opaque caps – a precast concrete topping, which can be used alone or in combination with a balustrade parapet.

Installation of concrete elements is simple and relatively fast, and does not require equipment for work at height. The caps are glued to the masonry facing blocks with frost-resistant mortar.
