Stepped & I-Shaped Slope Block Mould Buyer Guide

I-shaped (also called dogbone or H-shaped) slope blocks lock into each other along the slope by shape alone, which is why they are specified where a plain rectangular block would slide. This page holds 11 sizes from 26 to 50 cm long.

I-shaped vs half-I: what actually differs

Full I-shaped block: waisted on both sides, so it keys into neighbours on all four edges. Used across the main slope field.
Half-I block: waisted on one side and straight on the other. It is the edge and closing piece — you order it alongside the full block, not instead of it.
Interlocking I-shaped block: I-profile plus tongue-and-groove edges and open grass-planting voids, for slopes that need both mechanical keying and vegetation.

Three things buyers get wrong

Ordering only the full block. Every slope has edges. If you order 100% full I-blocks you will be cutting them on site to close the boundary. Work out the half-I quantity from the slope perimeter at drawing stage.
Reading the quoted size as the finished paved module. An I-shaped block interlocks, so the laid centre-to-centre spacing is smaller than the block's overall length. Ask for the laying module if you are calculating blocks per m².
Assuming same face size means interchangeable. This page has 40 × 30 cm blocks at 10, 12 and 15 cm thick, and two 50 × 30 × 10 cm blocks of different profile (I and half-I). Same footprint, different mould, different product.

Position on slope	Block to use	Key parameters
Main slope field	Full I-shaped block	Face size, thickness, waist width
Slope edges & closing course	Half-I block	Must match the field block's size and thickness
Slope needing vegetation	Interlocking I-shaped block with voids	Void count and open area
Higher flow / steeper slope	Thicker section (15 cm)	Thickness per structural design

Stepped Slope Block Moulds FAQ

What is a stepped slope block mould used for?

It is used to precast I-shaped or half-I concrete blocks for slope protection, river-bank revetment and embankment erosion control.

Can you make the mould from our drawing?

Yes. Send the finished block drawing, size, thickness and site application; we can review catalogue matching or OEM mould feasibility.

Can the block size be customized?

Yes. Length, width, thickness, interlocking details and surface patterns can be customized when the mould structure allows.
