ICF STRUCTUAL ELEMENTS OF ANDROULAKIS
Below you can see detailed information about the building materials used in the constructions we apply at Androulakis, as well as their characteristics and technology.
ANDROULAKIS ICF MASONRY
B500c steel of Greek origin.
The B500c reinforced concrete steel is the primary material ensuring the safety and strength of a reinforced concrete construction. Its main purpose is to provide resistance and stability to the structure, especially in cases of intense seismic activity.
The reinforcement steel (bars, meshes) strengthens the building’s load-bearing frame and prevents the concrete from cracking or breaking at critical points such as columns, beams, and slabs.
During seismic activity, the steel absorbs seismic energy and prevents damage to the building.
Due to the high seismicity of the region, strict adherence to the structural engineer’s study is required, along with the use of high-strength and ductile steel, according to ELOT 1421 standards.
The B500c steel used by the company is sourced from the Greek company SIDENOR, of excellent quality, meeting modern specifications, and is distinguished by its strength, ductility, flexibility, and weldability, in accordance with anti-seismic regulations and the new ELOT 1421 standard.

Concrete C25/30
Characteristics:
Resistant to various aggressive exposure environments.
Excellent mechanical strength
Excellent compressive and tensile strength
High quality and durability
Reduced water permeability, ideal for coastal environments
Resistant to surface wear
Resistant to chemical attacks
The strict provisions of the Concrete Technology Regulation of 1997 (C.T.R. 97) specify the minimum dosages of raw materials depending on the specific application of the concrete (such as workability, strength, plasticity, exposure environment, performance, and service life of the construction). The different properties of the raw materials mixed in concrete production (mass, volume, physico-chemical characteristics) make concrete production an extremely complex and sophisticated process.
Due to the high seismic activity in our country, both the production process and the final incorporation of the concrete into constructions are governed by the highly demanding Concrete Technology Regulation (C.T.R. 97), which is currently in effect, covering the requirements for modern, safe, and earthquake-resistant constructions.



PVC is harder and more durable than steel and can withstand very low and very high temperatures.
PVC is a thermoplastic polymer and can produce products with a wide range of mechanical properties (from flexible to rigid), has chemical resistance, and is difficult to ignite.
Smart Form is a material produced from solid polystyrene beads. It is rigid, environmentally friendly, has excellent thermal and acoustic insulation properties, is resistant to moisture, does not decompose, and consequently has a lifelong durability.
The ICF formwork provides double insulation for the building and remains as permanent formwork. Therefore, there is no need to wait for the concrete to harden, which significantly reduces construction time.
The ICF formwork technology also enables us to construct a building entirely from reinforced concrete, making the structure monolithic, solid, unified, and resistant to high seismic activity.

Exceptional density
Self-extinguishing material (does not propagate flames)
Manufactured according to European standards EN 13163
Thermal insulation

In drywall constructions, the metal framework is the supporting system created from pre-formed metal profiles (usually galvanized steel) onto which the plasterboards are screwed.
This framework is responsible for transferring loads (weight of plasterboards, doors, cabinets, etc.), ensuring the mechanical stability of the construction, and providing geometric accuracy (flatness, vertical alignment, and level surfaces).
The metal profiles are intended for dry construction systems and are the ideal solution for false ceilings and partition walls using plasterboards. They offer corrosion resistance, long lifespan, and structural stability.
Components:
Horizontal profiles (guides – UW or UD depending on the application): Fastened to the floor, ceiling, and walls.
Vertical profiles (studs – CW or CD): Placed at regular intervals and connected to the horizontal guides.
Depending on the type of construction (wall, false ceiling, or wall cladding), different types and cross-sections of profiles are selected.
