Product Catalogue
Engineered media, graded to specification
Every batch is screened, washed and verified against the gradation you specify — then shipped with a certificate of analysis that matches the bag in front of you.
6gradesThe core of every rapid gravity filterSilica Filter Sand
High-purity, sub-angular silica sand washed and graded for potable water, desalination pre-treatment and industrial filtration. Low acid solubility, low fines, consistent effective size lot to lot.
EN 12904AWWA B100View details
4gradesThe layers that keep the bed where it belongsSupport Gravel
Rounded, washed silica gravel in graded layers that support the filter media above the underdrain and distribute backwash flow evenly across the bed.
EN 12904AWWA B100View details
2gradesThe coarse top layer of a dual-media bedFilter Anthracite
Low-ash, high-carbon anthracite graded for dual and multimedia filters. Its lower density lets it sit above silica sand after backwash, giving depth filtration and longer runs between washes.
EN 12909AWWA B100View details
3gradesThe dense bottom layer for sub-micron polishingGarnet Filter Media
High-density almandine garnet for the fine bottom layer of multimedia filters, capturing particles that pass through sand and anthracite above.
EN 12910AWWA B100View details
3gradesFor taste, odour, chlorine and organicsGranular Activated Carbon
Coconut-shell and coal-based granular activated carbon for dechlorination, organic removal and taste-and-odour control in potable and process water.
EN 12915-1AWWA B604View details
2gradesThe whole bed, matched and shipped togetherMultimedia Filter Packages
Complete pre-matched media packages — anthracite, silica sand, garnet and the full support gravel set — sized to your vessel diameter and bed depth so nothing has to be reconciled on site.

2gradesMicronised silica for industrial formulationSilica Flour
Finely ground, high-purity silica in 200 and 325 mesh grades for paints, adhesives, sealants, refractories, ceramics and oil-well cementing.
ISO 9001 process controlView details
3gradesGlass, foundry and construction gradesIndustrial Silica Sand
Washed and graded silica sand supplied to glass-making, foundry, ceramic and construction specifications, with iron content controlled to the level each process demands.

4gradesFour finishes across marble, granite and quartzMarble Chips
Washed and graded decorative chips in four finishes — Edge, Velvet, Satin and Lustre — produced from a wide range of marbles, granites and quartz. Colour and size sorted across a whole production run, so a large floor or landscape reads as one batch.

3gradesSold separately, matched to the aggregateEpoxy Resin Binder
Two-component, UV-stable epoxy binder for stone carpet, epoxy terrazzo and resin-bound surfacing. Sold on its own rather than as a kit, so you can buy it with our aggregate or with your own.
EN 13813 SRISO 9001 process controlView details
3gradesSpreads, stays put, and works down to −7 °CDe-icing Salt
Coarse washed sodium chloride for highway, airfield and municipal winter maintenance. Graded so it lands on the carriageway and stays there — granulometry is specified alongside purity, because salt that blows away or bounces has not worked however pure it is.
EN 16811-1View details
3gradesChloride purity, and insolubles that stay out of your processIndustrial Grade Salt
Washed and dried sodium chloride at ≥ 98% NaCl for chlor-alkali feedstock, brine systems, textile dyeing, drilling fluids and bulk regeneration. Specified on insolubles and on calcium–magnesium as much as on chloride, because those are what show up downstream.
EN 973 (regeneration use)View details
3gradesMade on a segregated line, with the records to prove itFood Grade Salt
Washed, dried and screened sodium chloride at ≥ 99.1% NaCl for food processing — curing, brining, cheese, bakery and seasoning. Produced, stored and packed away from the de-icing and industrial lines, and released against a lot-specific certificate of analysis.

3gradesIodised, free-flowing, and packed for the shelfTable Salt Grade
Fine white sodium chloride at ≥ 99.4% NaCl, iodised to the destination market's mandatory level and packed in retail cartons, sachets or private-label formats. Judged on grain uniformity, whiteness and flow — which is what a filling line and a shaker both depend on.

3gradesSodium chloride, compressed — and it does not bridgeWater Softener Salt Tablets
Compressed sodium chloride tablets at 99.9% purity for regenerating ion exchange resin in domestic and commercial water softeners. Near-zero insolubles, uniform dissolution, and no bridging in the brine tank.
EN 973 Grade ANSF/ANSI 60 (potable softening)View details
3gradesThe sodium and chloride a forage ration cannot supplyAnimal Salt
Feed-grade sodium chloride for livestock — loose granular for mixed rations and pressed licks for free-choice feeding. Supplied plain, or mineralised with trace elements to your nutritionist's formulation.
Feed-grade sodium chlorideView details
3gradesGrinding media that adds no iron to the batchFlint Pebbles
Naturally rounded high-silica flint, washed and screened into mill charges. The non-metallic grinding medium for ceramic bodies, glazes, frits and pigments — anywhere iron pickup would show in the fired or finished colour.
Graded to customer specificationView details
4gradesWashed, graded and colour-sortedDecorative Pebbles
Natural river and quarry pebbles in graded sizes and sorted colour ranges for landscaping, water features, green roofs and architectural finishes.

How It Is Made
Four stages between the deposit and your filter bed
Raw silica from our Egyptian deposit moves through washing, drying, precision screening and controlled packing — with sampling points at every transition.
- 1
Extraction & washing
Raw silica is washed in a closed-loop circuit that removes clay, silt and organic matter before it ever reaches the dryer.
- 2
Drying
Rotary drying brings moisture below 0.5%, the threshold at which fine gradations screen cleanly instead of blinding the decks.
- 3
Precision screening
Multi-deck screens cut each gradation to the effective size and uniformity coefficient written on your specification.
- 4
Packing & dispatch
25 kg bags, 1-tonne jumbo bags or bulk — labelled, palletised and matched to a certificate of analysis.
Quality Assurance
Tested before it leaves. Documented when it arrives.
Our in-house laboratory runs sieve analysis, acid solubility, specific gravity, roundness and turbidity on every production lot. Nothing ships without a signed certificate of analysis.
