Built to Your Specification
Signature interior schemes, statement façades, landmark landscape features. When the project calls for a grain and a colour that aren't on a standard grade list, Alliance Silica® builds the blend. Warm, cool and mixed palettes, matched to swatch or brief, supplied in natural form - no dyes, no colour coatings.
Bespoke Silica Sand Blends - Grade, Grain Shape and Colour Matched to Your Brief

Alliance Silica® supplies bespoke grade, grain-shape and colour silica sand blends built around your specification. Warm-toned, cool-toned and mixed palettes matched to interior schemes, architectural façades and signature landscape features - supplied in natural form or blended to a target swatch using only untreated material.
We work directly with architects, interior designers, specialist finishers and landscape architects on signature project specifications - from first swatch conversation to final-blend supply, with sample packs approved before the project volume is produced.

Start With the Finish, Work Back to the Grain
A signature finish rarely sits on a standard grade. The grain size isn't quite right. The colour is close but not close enough. The shape needs adjusting for a particular trowel, a particular pour, a particular surface behaviour. Standard catalogue grades can't answer every brief - the answer is a blend.
Alliance Silica® builds bespoke blends from our natural silica sand network - no dyes, no colour treatments, no bulking fillers. Warm-toned, cool-toned and mixed palettes, grain-shape blends, and grade distributions engineered to the specification. The process starts with a swatch and a brief; it ends with a sample pack you approve before we produce the volume.
