Commercial concrete panels are usually 5" or 6" thick, but these walls may have just 2" or 3" thick concrete. It could easily last 100 years, but we're often taught that 3" cover over each side of embedded steel is the minimum to avoid long term corrosion, regardless of the steel coatings.
Precast wall for industrial building are usually flat but increased in height customised to match the storey height. The load bearing structural walls ranges from 150 to 200mm thickness. The non load bearing walls are usually 100mm to 125mm thickness.
wall thickness ranging from 16 cm to 38 cm. thickness of a single layer in a composite wall ranging from 5 cm to 7 cm. weight of the prefabricated element stretches from 250 to 350 kg / m2 of the wall.
So when it comes to the actual thickness of a concrete foundation wall, the rule of thumb is a minimum of 8 inches, and then 10 inches thick for walls taller than 8 feet. This should allow for higher PSI as well (pounds per square inch), which should be between 2,500 and 3,000 in residential construction.
The durability and flexibility of precast concrete also make it a reliable and versatile building material. However, precast concrete has several disadvantages, including transportation and installation challenges, potential environmental impact and unique maintenance requirements.
A minimum thickness of the precast wall panels is 125 mm when reinforced and 150 mm where a vertical projecting bar from the footing or floor engages with a dowel duct in the bottom of the precast panel. For panels up to 175 mm thick, one layer of central mesh is generally used above that, two layers are used.
The fire-resistance rating of concrete masonry walls depends on the type of aggregate used in the units. A 2-hour rating can be achieved by a wall with an equivalent thickness of as little as 3 1/5 inches when expanded slag or pumice is used or 4 1/2 inches when siliceous gravel is used as the aggregate.
The concrete core may vary from 140 mm to over 300 mm depending upon the structural design, while the two leaves of insulation may vary from 100 mm to 300 mm depending on the thermal insulation specification. Consequently, total wall thickness may be between 250 mm and 600 mm.
Most blocks are available in five thicknesses of 90mm (Series 100), 110mm (Series 120), 140mm (Series 150), 190mm (Series 200) and 290mm (Series 300). National Masonry® Victoria offers many 'fractional' sized blocks to reduce the need for on-site cutting.
How much does a precast compound wall cost? The price of compound walls ranges from Rs 60 to Rs 500 per sq. ft.
These panels can be made from various materials, including wood, steel and concrete (and can be designed to fit a wide range of building needs). Prefabricated walls can be used in various construction projects, including homes, commercial buildings and modular office walls.
Depending on the thickness of the panel and the glass block selected, the precast wall panel weight is approximately 10 pounds per square foot.
Precast concrete can develop cracks due to tension, environmental factors like temperature and wind, as well as shrinkage during the curing process. Common types of precast concrete cracks include longitudinal hairline cracks, transverse cracks, diagonal cracks, random map cracking, corner cracks, and step cracks.

Prefabricated Exterior Wall Panels serve as a strong and efficient alternative to precast concrete panels with advantages like easier handling, quicker installation, better thermal insulation, and increased cost-effectiveness.
Cement precast compound wall is a type of concrete that is cast in place and provides an extra layer of protection for the foundation of the building.
ICF walls come in 4”, 6”, 8”, 10” and 12” thickness (some manufacturers go even thicker). Generally, 4” walls are only used for non-loadbearing applications such as demising walls in apartments, hotels or dormitories. 5.
As a practical consideration, residential designers need to keep in mind that concrete foundation walls are typically 6, 8 or 10 inches thick (nominal).
Sandwich Panel Thickness
An exterior wythe of concrete measuring around 75 mm (3”) thick (although it may be as thin as 2”) A layer of rigid foam insulation (typically extruded polystyrene) that is between 50-100 mm (2 – 4”) thick. A load-bearing interior wythe measuring between 125-250 mm (5-10”) thick.
Concrete should be at least 2 inches thick to maintain its stability and quality. Most concrete slabs fall between 4 and 6 inches thick, but you should be careful not to make the new slab too high or heavy.
RECOMMENDED CONCRETE THICKNESSES
Light Use: 4" concrete - Parking for passenger cars, light trucks and occasional use by heavier trucks. Medium Use: 5" to 6" concrete - Driveways and parking areas for light to medium trucks plus occasional use by heavier trucks.
Precast concrete floor panels typically come in a standard thickness range of 6 to 12 inches, with the most common thickness being 8 inches.
Precast concrete wall panel dimensions vary based on individual project design requirements. They generally average approximately twelve feet in width by forty feet in height but can be manufactured to over sixty feet in height.
