What are the advantages of Betonblock® interlocking concrete moulds?

Betonblock® moulds are made of high-quality S355 steel and are powder-coated to create a hard scratch and impact-resistant layer. This coating also prevents the steel from rusting and comes in many different colours. The moulds are built to last and will continue to deliver for at least 10 years. The interlocking Concrete Block® moulds feature a unique closure that ensures that the moulds are easy to use and dimensionally stable, so you can keep producing identical stackable concrete blocks year in year out. Our high-quality moulds produce uniform blocks that fit together seamlessly and create sturdy structures. Many Betonblock® customers have been making blocks with the same mould(s) every day for a decade without any of the moulds warping.

Start casting right away

Betonblock®'s robust steel moulds come as a full kit, including mould opener, so you can start producing interlocking concrete blocks right away. Tip! Spray the mould with Betonblock® formwork oil prior to casting. If you do not apply the oil first, the mould may not release the concrete. On top of that, the oil also helps keep the mould in tip-top condition, so it will last longer.

Less than €1 a block!

Betonblock® moulds are high-quality products that are built to last, making them suitable for more than decade’s worth of daily usage. Based on the following calculations: 250 days per year (excluding weekends and holidays) x 10 years = 2,500 concrete blocks from one mould. Our best-selling concrete Lego block mould, Basic 160x80x80, costs €1,675. Resulting in a grand total of: € 0.67 for each concrete block!
