Frequently asked questions about the Concrete blocks category
What are Concrete blocks and what are they used for?
Concrete blocks are precast masonry units made of heavy or lightweight concrete, available as solid or hollow blocks, used for walls, foundations, fences and landscaping. The category includes foundation, wall, decorative and insulating blocks in various sizes, densities and strength classes.
What variants of 20×20×40 concrete blocks are available and how do they differ?
20×20×40 blocks are offered as solid and hollow types: solid blocks provide higher compressive strength while hollow blocks are lighter and easier to handle. Choose denser solid blocks for foundations and load-bearing walls, hollow blocks for non-structural partitions and insulation needs.
Which concrete blocks are suitable for a fence?
Use wall or decorative blocks with good frost resistance and adequate density for fences. Hollow blocks work for lighter fences, while solid blocks are preferred for taller or more robust enclosures; corner and post blocks are available for neat installation.
Which blocks are suitable for walls and partitions?
For load-bearing walls choose dense solid or reinforced hollow blocks with higher strength; for internal partitions use lightweight hollow or aerated blocks. The range includes insulated and finished-face blocks for easier exterior/interior finishing.
What blocks are used for fence posts?
Use dedicated post or corner concrete blocks with higher density and shapes that allow anchoring reinforcement. The catalogue includes post and corner elements designed to simplify installation and ensure structural stability.
Which concrete blocks are suitable for foundations?
Choose foundation blocks with high density and compressive strength; solid blocks are typically preferred for load-bearing foundations. The category includes foundation-specific blocks designed to transfer loads and provide underground stability.
Can concrete blocks be used to mount solar panels?
Yes — heavy concrete or foundation blocks can be used to mount solar panels, providing the static load capacity and stability required. When choosing, consider panel weight, wind loads and the ability to fix mounting rails or anchors to the block.
How are concrete blocks used on roads?
Concrete blocks are used as kerbs, protective barriers, supports for temporary fencing and landscaping elements along roads. Road applications require dense, frost-resistant blocks that withstand mechanical stresses and traffic-related loads.
How to choose between hollow and solid blocks?
Choose solid blocks for load-bearing structures and foundations when higher strength is required; hollow blocks suit partitions, lightweight walls and where lower weight and insulation are priorities. Assess structural loads, required strength and thermal properties before selecting.
What parameters should I check when choosing a block (density, strength, size)?
Check block dimensions (e.g. 240×190×585 and other standard sizes), material density (heavy or lightweight concrete) and compressive strength class — these determine load-bearing capacity and thermal performance. Also verify reinforcement options, frost resistance and surface finish (decorative or smooth).
