Modular concrete blocks «LEGO»

LLC «PVK ARSENAL» offers a wide range of reinforced concrete products that meet the modern requirements and criteria of the construction industry.

Modular concrete blocks (a fortification reinforced concrete block of the «LEGO BLOCK» type) manufactured by LLC «PVK ARSENAL» have a wide range of applications across various areas of construction — building fortifications, laying foundations and retaining walls for premises of any purpose.

Thanks to their design features — a «tongue-and-groove» interlocking system in the horizontal plane — structures made of modular blocks are assembled with maximum geometric precision and density. Assembly also requires no cement mortars or other adhesive mixtures. These technological features significantly speed up construction while substantially reducing the cost of technical and human resources.

Fast installation, structural reliability and the versatility of modular concrete blocks provide broad application possibilities when building protective structures in emergency or force-majeure situations — construction of fortifications, underground bomb shelters and above-ground shelters, checkpoints and temporary barriers; protective structures for critical infrastructure facilities; barriers and retaining walls during floods and high water, bank reinforcement and jetty arrangement, artificial fire-fighting reservoirs; erection of temporary warehouse and industrial premises, and more.

PVK ARSENAL offers modular blocks at a price that ensures maximum convenience and savings for your construction project.

We guarantee the quality of our reinforced concrete products. Manufacturing of reinforced concrete products at LLC «PVK ARSENAL» is certified in accordance with the international standards ISO 9001:2018 «Quality management systems», ISO 14001:2015 «Environmental management systems», AQAP 2310 «Quality management systems for defence contracts» and ISO 37001:2018 «Anti-bribery management systems», which set requirements for the production, technological and financial processes of our organisation.

All reinforced concrete products of LLC «PVK ARSENAL» are manufactured in accordance with the requirements of the standards (DSTU) for concrete products:

• DSTU EN 14991:2022 Precast reinforced concrete products. Foundation elements

• DSTU B V.2.6-2:2009 Constructions of buildings and structures. Concrete and reinforced concrete products. General specifications

• DSTU EN 13670:2023 Building structures. Execution of concrete structures, and others.

Heavy concrete of class C40 (W10, F300) with reinforcement. The connection between blocks is a «tongue-and-groove» system in the horizontal plane: a pyramid-shaped tongue fits into the corresponding groove without cement mortar or adhesive mixtures. Installation is carried out with a crane or a manipulator.

The height of all sizes is 600 mm (actual 580 mm). Width: 300 mm (one row of tongues) or 600 mm (two rows). Length — 600, 1,200, 1,800 or 2,400 mm (actual dimensions are 20 mm smaller because of the tongue joint).

Additional versions: a «zero» block — without tongues on top, for the upper row where floor slabs are installed; a block with reinforced armouring and metal connecting strips along the longitudinal edges for welded connections between blocks.

Standard LEGO BLOCKS manufactured by LLC «PVK ARSENAL» differ in their linear dimensions and in the number of rows of the «tongue-and-groove» connection system. In length they are 0.6 m, 1.2 m, 1.8 m and 2.4 m; in height — 0.6 m; in width — 0.3 and 0.6 m — for one row and two rows of tongues and grooves respectively.

Example of the designation: МБ-18.3.6т, where:

МБ — modular block, 18 — length in dm (L), 3 — width in dm (b), 6 — height in dm (h), т — heavy concrete.
