Colored, Decorative & Grass Paver Moulds Buying Guide

“Colored paver moulds” (彩色路面砖 / cai zhuan) cover a surprisingly wide family: everything from hollow units that grow grass, through municipal accessibility tiles, to decorative tiles embossed with flowers and leaves. Buyers run into trouble when they treat them as one product. This guide separates the families and lists the points that actually decide whether a paving job succeeds.

1. The five paver families in this range

• Permeable / grass-grid pavers. Hollow units with through planting holes. Our range has hexagonal units (outer 12.5 and 13.5 cm, inner holes 5 and 5.5 cm) and a large 48 × 24 × 8 cm serrated slab with two circular through holes. Holes are filled with soil and seed (or gravel) after laying.
• Tactile pavers. Accessibility tiles for visually impaired pedestrians: blister (raised dot) warning tiles and strip (directional) tiles, in 20 × 20 × 6 cm and 25 × 25 × 5 cm, normally bright yellow.
• Shaped / interlocking pavers. Diamond, bow, arrow, clover, crescent, tooth and serrated shapes that interlock or build landscape patterns, plus combination sets.
• Square & interlocking workhorses. 18–30 cm square colored pavers (including 2–3 cm thin overlays), I/H-shaped interlockers and anti-slip grid-face tiles — the volume sellers for sidewalks and community roads.
• Patterned decorative tiles. Embossed faces — maple leaf, plum blossom, chrysanthemum, diamond, Spanish, nine-grid and double-fan — plus small 12.5 cm hexagons, for courtyards, parks and scenic paving.

2. Solid vs hollow — the first question to answer

Most “colored pavers” are solid tiles that simply pave. Only the permeable hexagons and the holed 48 cm slab in this range are hollow: their through holes exist to drain stormwater and grow grass (sponge-city / green-parking applications). A common mistake is buying shaped decorative tiles that look lacy and assuming they will drain — clover and crescent shapes are solid; check for actual through holes before specifying a permeable pavement.

3. Grass-grid pavers fail on sub-base, not on the tile

A hollow grass paver carries light vehicle loads only when the system is built correctly: open-graded crushed-stone sub-base (free-draining), compacted and level, geotextile separation where specified, holes filled with a soil/gravel mix suited to the seed. Poured onto a flat sand bed with no drainage, the grass dies in weeks and the slab cracks under tyres. The mould is the easy part — the base design is what buyers forget.

4. Thickness means duty

• 2–3 cm: overlay/veneer tiles bonded onto sound existing pavement — not structural.
• 4–5 cm: foot traffic — sidewalks, plazas, courtyards.
• 6 cm: community roads and light vehicle areas, especially interlocking shapes.
• 8 cm: occasional vehicle loads (serrated/drainage slabs, thick interlockers).

Interlocking I/H and tooth shapes outperform plain squares on vehicles because the joints transfer load across the pavement — that is why driveway specifications call for interlockers, not large plain slabs.

5. Patterns are laid, not just cast

Four-piece motifs (plum blossom, chrysanthemum) need four tiles per complete flower: order in multiples of four, and decide the laying direction before work starts. Continuous patterns (Spanish, double-fan) likewise need a direction plan and consistent pouring orientation. Sort this out at the layout stage — rotating a quarter-tile after the concrete has set means cutting out finished pavers.

6. Color is made in the mix

Colored pavers get their color from iron-oxide pigment mixed into the concrete (typically 2–5% of cement weight by color depth). For thick tiles a pigmented wear-course layer poured first, then plain base concrete, gives the same surface color at lower pigment cost. White cement is used for bright pastels; grey cement for deep reds, yellows and greens. PP and ABS mould faces don't react with oxide pigments and release cleanly, so the color stays even tile to tile.

7. Tactile tiles are a compliance item, not decoration

Blister dots = stop/hazard/turn warning; long strips = safe directional line. Municipal sidewalks, stations, hospitals and public buildings require them, usually in attention-grabbing yellow. If a project includes public-access paving, the tactile tiles should be in the same mould order as the running pavers so heights and batch color match.

8. Cavities, materials and output

“1-out-N” is the number of tiles per pour — a 1-out-9 mould makes nine rough-stone tiles in one cycle, cutting cost and labour per tile on volume runs. PP is the default (150+ cycles, flexible demoulding); ABS is chosen for deep crisp motifs and fine textures that must stay sharp. Compare quotes per finished tile and per daily output, not per mould.

Build a balanced first order

If you are importing paver block moulds for the first time, a mixed-SKU order is usually safer than committing to one pattern. A practical mix pairs a few high-volume workhorses — 25–30 cm square/interlocking colored pavers and I/H-shaped interlockers for sidewalks — with a smaller set of decorative shapes (maple leaf, crescent, four-piece flower motifs) and one or two permeable grass-grid or tactile items to win municipal and parking jobs. This lets you test which shapes your local market actually buys before reordering in volume; mixed-SKU packing is standard and there is no strict MOQ per design.

What to send for a fast quote

• A layout sketch or photo of the paving effect you want
• Tile size and thickness (outer/inner for hollow units)
• Application: footway, driveway, parking, fire lane, plaza or tactile path
• Solid or hollow (grass/permeable)
• Pattern and motif counts (remember multiples of four for flower sets)
• Cavities wanted (1-out-N), PP or ABS, quantities and destination port
