Foundation blocks
FBS foundation blocks are precast concrete elements used to build basement walls, plinths, retaining walls and equipment bases. The blocks arrive on site ready-made and are installed by crane, so the foundation is faster and more predictable than a cast-in-place one: no formwork, no on-site reinforcement, no dependence on the weather.
Field of application
FBS foundation blocks are used for erecting precast foundations and underground structures in residential, commercial and industrial construction.
Main areas of use:
- laying strip foundations
- building walls of basements and technical floors
- construction of the plinth (base) parts of buildings
- forming foundations for columns and load-bearing structures
- retaining walls and engineering structures
- technical chambers, shafts and pits
FBS blocks are used in both low-rise and high-rise construction, as well as at industrial facilities with increased loads.
Thanks to factory manufacturing, the blocks ensure fast installation and high load-bearing capacity of the structure.
Technical features
FBS are massive rectangular reinforced concrete blocks made from heavy concrete using a factory method with strict quality control.
Main characteristics:
- Made from heavy concrete of class B7.5–B15
- High load-bearing capacity
- Frost resistance (F50–F150)
- Water-tightness W2–W6
- Lifting loops for ease of installation
- Geometric precision of dimensions
Advantages:
- fast foundation construction
- no formwork required
- installation possible at any time of year
- durability (service life of more than 50 years)
- resistance to soil loads
FBS can be used in conditions of high humidity and seasonal freezing of the soil.
Types and varieties of FBS blocks
Example of the designation:
ФБС 24.4.6-Т
- 24 — length (≈ 2380 mm)
- 4 — width (400 mm)
- 6 — height (580 mm)
- Т — heavy concrete
Advantages of foundation blocks
FBS foundation blocks are used in practically any type of construction — wherever basement premises are planned, the groundwater level is high, or a fast foundation installation is required.
Compared with a monolithic foundation, precast FBS blocks offer a number of advantages:
- high strength and structural reliability
- moisture resistance and frost resistance
- low thermal conductivity
- fast installation without formwork
- a long service life
- savings on labour costs
