If you are planning a retaining wall project in Cranbrook or the surrounding Kootenay region, you already know that our weather doesn’t mess around. Between heavy winter snows and rapid spring thaws, your landscaping materials need to be tough.
When shopping for retaining wall blocks, you will usually run into two manufacturing terms: dry-cast and wet-cast concrete. They might look similar from a distance, but how they are made fundamentally changes how long your wall will last. Here is the breakdown.
What is Dry-Cast Concrete?
Dry-cast concrete is made with a low water-to-cement ratio. The mix is relatively dry and is compacted into molds using intense vibration, allowing the blocks to be removed from the mold and cured almost immediately.
The Pros: It is fast to manufacture and generally less expensive. It’s perfectly fine for small, decorative garden borders.The Cons: Because it uses less water and relies on compaction, dry-cast concrete is porous. In a climate like ours, water seeps into those pores, freezes, expands, and eventually causes the block to crack, spall, or crumble over time.
What is Wet-Cast Concrete?
Wet-cast concrete uses a much higher water content—similar to the concrete poured for driveways or foundations. It is poured into a mold and has to fully cure before the mold is removed. This is the process used for the Redi-Rock Ledgestone blocks we supply here at FAFO.
- The Pros: Wet-cast concrete is incredibly dense and non-porous. This means it is highly resistant to freeze-thaw cycles, making it structural-grade and exceptionally durable. The wetter mix also allows for high-definition textures, mimicking the exact look of natural stacked stone.
- The Cons: It takes longer to manufacture and is heavier, meaning you need machinery to place large structural blocks.
Why FAFO Recommends Wet-Cast for the Kootenays
When you are holding back tons of earth, dealing with spring runoff, or building a commercial retaining wall, you cannot afford to use porous materials.
Because Redi-Rock Ledgestone blocks are wet-cast, they offer architectural-grade durability. They won’t crumble after a harsh British Columbia winter. Plus, with each massive block covering 5.75 square feet of face, your installation is faster and more secure than stacking hundreds of smaller dry-cast bricks.
