5 Types of Blocks You Should Know About 

While classic blocks like 9-inch, 6-inch, and 4-inch solid and hollow blocks have served us well, they’re no longer the only option. Today, innovative and versatile blocks are reshaping how we build, offering smarter solutions that save time, reduce waste, and improve the overall stability of your projects. 

Let’s dive into these types of blocks: 

Decking Blocks: Typically, square or rectangular, ranging from 8×8 inches to 12×12 inches, with slots or grooves for decking support. They are designed to support decking boards, giving you a stable base for your deck. Perfect for elevated decks, low-level decks, or decks built on uneven ground. 

Pillar Blocks: Rectangular blocks with dimensions like 6x12x12 inches or larger, depending on load requirements. Often have hollow cores to allow for reinforced filling. These blocks are perfect for creating a solid base for deck posts or building sturdy columns. They efficiently transfer weight to the ground, providing a secure and reliable foundation for your projects. 

Lock and Align Blocks: Uniform rectangular blocks (e.g., 8×16 inches) with interlocking grooves or tongues for easy alignment. They ensure perfect alignment and stability in your structure preventing shifting and ensuring your building stays secure. They help reduce errors during installation and save you time on adjustments. 

Beam Blocks: They are rectangular, typically longer and narrower, such as 4×12 inches or 6×16 inches, for beam construction. Beam blocks are designed for creating strong and stable beams that can carry heavy loads. Whether you’re constructing floors or walls, beam blocks provide the support you need to ensure your project stands strong under pressure. 

Fancy Blocks: Decorative shapes and sizes, such as 12×12 inches or custom dimensions with intricate patterns. Fancy blocks are the perfect choice for adding a touch of style to your project. These decorative blocks come in a range of designs and finishes, making them ideal for creating visually stunning walls, facades, and landscaping features. 

Advantages of using these types of blocks: 

  • No waste 
  • Easy installation  
  • Increased load bearing capacity  
  • Nice and smooth finishing
