Hollow & Interlocking Slope Block Mould Buyer Guide

These 10 moulds all produce blocks that key into their neighbours, but the keying mechanism differs — and that mechanism, not the block size, is what determines whether the slope holds.

Four keying mechanisms, four use cases

Tongue-and-groove interlocking: straight ribs and slots on the block edges. Simple to lay, resists sliding down-slope.
Dovetail interlocking: wedge-shaped joints that cannot be pulled apart in-plane. Specified where uplift or wave action is a concern.
Locking blocks: square 43 × 43 × 10 cm format that keys on all four sides for a uniform grid.
Hollow ecological blocks: open grass-planting voids plus interlocking edges, so the slope both vegetates and stays keyed.

Three things buyers get wrong

Treating "interlocking" and "dovetail" as the same product. They are not interchangeable: a dovetail joint resists being pulled apart, a plain tongue-and-groove joint mainly resists sliding. Confirm which one your design requires before comparing prices.
Quoting from the outer size when the interlock adds to it. The tongue projects beyond the block body. Two blocks both described as "40 × 34 cm" can have different overall mould footprints depending on how the interlock is measured.
Underestimating demoulding on deep interlocks and voids. Deep dovetails and open grass-planting cells are the highest-risk features for demoulding damage. This is a real production constraint — plan release agent and demould timing, and expect it to affect achievable cycles per day.

Hollow / Interlocking Slope Block Moulds FAQ

What is the benefit of hollow ecological slope blocks?

The hollow area can support vegetation or drainage while the concrete frame helps protect the slope from erosion.

What information do you need for an interlocking block quote?

Send block length, width, thickness, joint/interlock details, sample photo or drawing, quantity and destination country.

Can different hollow and interlocking sizes be packed together?

Yes. Mixed-SKU packing can be discussed based on quantity, mould size and export packaging requirements.
