Building & Construction
Open time and water retention that suit the applicator, strength and durability that suit the spec, and a mortar that stays workable at the temperature it is actually laid.
Water retention & workability
Rheology modifiers and water-retention additives for tile adhesives, renders, plasters and levelling compounds.
Strength & durability
Metakaolin, limestone fillers, high alumina cement and reactive pozzolans for performance and longevity.
Hydrophobicity
Water-repellent additives for facade renders and exposed mortars where absorption drives failure.
Lightweight & insulation
Perlite and vermiculite for insulating mortars, fire protection and weight reduction.
25 grades for building & construction
Minerals and specialities together. Narrow by product group or search by name and property — samples can be requested for these grades, with CoA, SDS and REACH status.

ATH (Aluminium Hydroxide)
Aluminium hydroxide has good fire retardant properties and is very effective as a smoke suppressant in a wide range of applications such as polymers and rubber.

Bentonite
A highly absorbent and viscous plastic clay, used as a binding, sealing, absorbing and lubricating agent.
SpecialityBiocides
In-can and dry-film biocides for waterborne coatings, adhesives and construction products. Use biocides safely. Always read the label and product information before use.

Calcium Carbonate
Both treated and untreated Ground Calcium Carbonate (GCC), marble and chalk grades.

Coloured & Uncoloured Quartz
Dorfner coloured and natural quartz sands and mixes for decorative flooring, renders and construction systems. Our agency covers Benelux and France.

Dolomite
A calcium magnesium carbonate making up to 2% of the earth's crust, used across a wide variety of applications.
SpecialityFatty Acids & Esters
Fatty acids and ester lubricants for polymer processing and construction chemistry.

Fluorspar
Fluorspar (fluorite) has physical properties that suit a wide variety of chemical, metallurgical and ceramic processes.

Fly Ash
Pozzolanic fly ash for construction and cementitious systems.

High Alumina Cement
Calcium aluminate cements consisting predominantly of hydraulic calcium aluminates.

Hydrated Calcium Borate
A mineral flame retardant and smoke suppressant for polymer and ceramic systems.

Limestone 200 ppm Fe₂O₃
We are the sales agent for industrial applications of Calcaires de la Sambre. With high purity and very low iron content (max 200 ppm Fe2O3), this is a unique product for the glass industry, in coarse grades 0-2 mm and 0-3 mm and finer fillers.

Magnesite
A magnesium carbonate mineral used as a refractory material, catalyst and filler, and for the preparation of magnesium chemicals and fertilizers.

Metakaolin
A reactive pozzolan improving the strength and durability of cementitious systems.
SpecialityMetallic Soaps & Stearates
Metallic soaps, stearates, esters and fatty acids as lubricants, release agents and acid scavengers for polymer and construction systems.

Natural Calcium Sulfate
Natural calcium sulfate — anhydrite and gypsum grades — for construction, animal feed and carpet-backing applications.
SpecialityRheology Modifiers
Rheology modifiers and thickeners to set flow, sag resistance and open time.
SpecialityRust Converters
A new generation of rust converters for maintenance and protective coating systems — the ASCOTRUST range.

Sodium Bicarbonate Technical
Technical grade sodium bicarbonate for industrial processes and flue-gas treatment.

Stainless Slag Filler (Fillinox)
Mineral filler recovered from stainless steel slag for construction applications — a short-chain, circular-economy alternative to primary aggregate.
Styrene Acrylic Resins
Styrene-acrylic dispersions for waterborne paints, renders, primers and construction products.
Thickeners
Cellulosic and associative thickeners to set viscosity, flow and open time in waterborne paints and construction products.

Vermiculite
Vermiculite undergoes significant expansion when heated. It is used in construction, the automotive field, high-temperature and industrial insulation, and horticulture.
SpecialityWater Repellent Additives
Hydrophobic additives for construction mortars and coating formulations.
SpecialityWetting Agents
Substrate and pigment wetting additives for waterborne systems.
Formulated for the site,
not the laboratory
Dry mortar is applied by people in weather. Open time, slip and water demand matter more than a 28-day figure on a certificate.
- ✓Applicator-side thinking. We help set the additive package around how and where the product is actually laid.
- ✓Samples with data. Full technical data with every sample — not just a bag and a phone number.
- ✓Scale-up support. Once qualified, we lock in the supply route, packaging and stock level before you launch.
- ✓Second source planning. Where it matters, we help you qualify an alternate grade in advance rather than during a shortage.
