You lay 抛光鹅卵石 by clearing 和 levelling the area, laying a permeable weed membrane, fixing a rigid edge restraint, then dry-setting a 30–40 mm layer 和 lightly compacting. One tonne covers about 12–18 m² at a 40 mm depth, 和 a 20 ft container holds about 24–27 tonnes — enough for 1,400–2,200 m². Plan the job as a near-view feature: the polished coat earns its keep where people look closely, 不会 on a driveway or a loose running path.
The steps below follow the order the work actually happens. First the base, because polished stone shows every dip 和 weed the moment the gloss catches light. Then the edge, because rounded 抛光鹅卵石 migrate faster than any other grade. Then depth 和 tonnage, then where they belong — 和 just as importantly where they do 不会 — then how to order a consistent, repeatable batch from a supplier.
Remove turf, roots 和 the top 50–75 mm of soft soil, rake the sub-base flat with a slight fall away from buildings, 和 lay a woven or non-woven permeable weed membrane directly on the prepared ground. The membrane blocks germination from below while letting rain through, 和 it stops the pebbles sinking into mud after the first wet season — which matters more here than with plain stone, because a sunken polished pebble loses its highlight 和 reads as dull grit.
Fix a rigid edge restraint — steel, aluminium or treated timber set 10–15 mm proud of the finished level — at every boundary. Polished pebbles are the smoothest, most mobile grade in the range, so without an edge the first hose, leaf-blower or boot pushes them onto the lawn or paving within weeks. Overlap the membrane 100 mm under the edging so weeds cannot enter at the seam, 和 avoid acidic or solvent cleaners on the laid bed, because they strip the gloss coat you paid for.
Coverage is driven by bulk density 和 broadcast depth. Loose 抛光鹅卵石 run about 1.5–1.7 tonnes per cubic metre. At a 40 mm depth one tonne covers roughly 12–18 m² — use the lower figure for fine 8–12 mm grades that nest tighter, the higher for 20–40 mm grades with more void. At 30 mm the same tonne stretches to about 16–22 m², but thinner layers expose the membrane 和 let weeds through, which is the fastest way to ruin a polished bed.
At container scale a 20 ft box holds about 24–27 tonnes of 抛光鹅卵石, covering roughly 1,400–2,200 m² at 40 mm — it hits the weight limit before it fills the cube, so most importers mix two or three size bands in one shipment. Always add 10% for compaction, spillage 和 the later top-up every display eventually wants, 和 order the full project quantity from a single lot so the batch tone cannot drift between deliveries.
Polished pebbles belong in near-view work: planters 和 raised beds, entry courtyards, feature borders, indoor atriums, 和 the bases of fountains 和 water features where the gloss catches the water. That is where a polished coat repays its premium — it reads as deliberate, clean 和 high-spec up close, 和 it lifts a planting scheme the way a matte stone cannot.
They do 不会 belong on driveways or any loose vehicle surface, 和 they are a poor choice for a barefoot poolside running area. The coat wears under abrasion 和 the smooth round shape rolls 和 packs into tyre treads or scatters under foot, so a polished bed should be a stabilised border (resin-bound or grid-stabilised) at a drive edge, never the running surface. For open walkable fields, choose a matte or angular grade instead 和 keep polished stone for the accents.
Yes, as an accent — 和 this is exactly where 'best 抛光鹅卵石 for dry river bed' thinking helps. A dry river bed is built structurally from rounded washed gravel (a 20–40 mm body with 40–75 mm anchor stones), 和 a thin band or scatter of 抛光鹅卵石 along the channel edge catches light 和 reads as moving water. Use polished stone for the highlight strip, 不会 the whole bed, because the gloss coat is cosmetic 和 the bed's job is drainage 和 shape.
Keep the rock family inert — granite, quartz or basalt — so the polished pieces do 不会 leach or stain the surround, 和 if the dry stream feeds a pond, confirm the supplier's coat is non-toxic 和 fish-safe before any piece enters the water. The structural gravel 和 the polished accent should come from the same family 和 be wet-sealed together so the dry 和 polished states stay coherent when the bed is hosed down.
Ordering starts with the supplier 和 the coat specification, 不会 the price. A credible 抛光鹅卵石 supplier runs a tumbling 和 coating line that can hold gloss level 和 colour across lots 和 supply a wet reference sample, 不会 a trader re-bagging whatever is on the yard. Confirm the rock family is inert 和 specify the coat type — wax, resin or polymer — in writing, because each wears at a different rate 和 only some are safe around water.
The practical minimum is one 20 ft container of about 24–27 tonnes loose, but most suppliers will split that across two or three size bands so a first order can carry both an 8–12 mm accent grade 和 a 20–40 mm body grade. Choose 25 kg bags for retail resale or FIBC jumbo bags for sites, write 'washed', the millimetre band 和 the lot reference into the order, 和 close with a pre-shipment inspection plus a retained sealed sample so every future top-up still matches the bed you built.
Clear 和 level the area, lay a permeable weed membrane, fix a rigid edge restraint, then dry-set a 30–40 mm layer 和 lightly compact. One tonne covers about 12–18 m² at a 40 mm depth, 和 a 20 ft container holds about 24–27 tonnes — enough for 1,400–2,200 m². Keep them in near-view beds, 不会 on driveways.
Lay them 30–40 mm deep over a membrane. At 40 mm one tonne covers roughly 12–18 m² (less for fine 8–12 mm grades, more for 20–40 mm), 和 at 30 mm it stretches to about 16–22 m². Thinner than 30 mm exposes the membrane 和 lets weeds through, which ruins the polished look fastest.
关于我们 12–18 m² per tonne at a 40 mm depth, based on a bulk density of 1.5–1.7 tonnes per cubic metre. A 20 ft container of 24–27 tonnes therefore covers roughly 1,400–2,200 m², 和 you should add 10% for compaction, spillage 和 later top-ups.
Yes, as a light-catching accent strip along the channel edge, but build the bed structurally from rounded washed gravel (20–40 mm body, 40–75 mm anchors) 和 use polished stone only for the highlight. Keep the rock inert 和, if the stream feeds a pond, confirm the coat is non-toxic 和 fish-safe before any piece enters the water.
