CTX BasicAgglo® Micro Sivec

The aggregate. “Sivec” denotes the high-purity white marble from the Pelagonian zone south-west of Prilep in North Macedonia (the Pletvar, Sivec and Belovodica quarries). It is a fine-crystalline calcite marble with above-average brightness, very low iron content and a sugary grain fabric. In the slab, the micro chippings (≈ 0.7–2 mm) preserve the optical purity of the natural marble — from a medium distance the polished surface looks almost single-coloured, from bright white to warm cream-white; close up, a subtly fine dot mosaic appears with only slight light-dark contrast.

The classic generation. “Micro Sivec” is the established, older mixture in the CTX BasicAgglo family. Compared with the newer “New Micro Sivec” variant, this generation carries a warmer, somewhat creamy ivory base tone, because the binding resin is set minimally darker and the pigment balance tends towards the beige side. Both variants share format, slab thicknesses and fabrication profile; the choice is a question of the desired tone — “New” for a cool white, “Classic” for a warmer ivory impression.

Format and fabrication. Civet usually supplies the agglomerate slabs in large formats around 305 × 144 cm or 320 × 160 cm in the standard thicknesses of 2 and 3 cm; individual lines also thinner for wall claddings. The slabs can be cut, profiled, calibrated and drilled with diamond tooling like a dense marble engineered stone. Because of the polyester binder, thermal load capacity is considerably lower than with pure natural stone — do not set hot pots, irons, radiant heaters or hairdryers down directly on the surface, and consistently avoid sustained temperatures above 80–90 °C. Direct UV exposure causes the resin to yellow over the long term, which is why the material is intended exclusively for interior fit-out.

The ROSSITTIS range. The surface finishes available in stock are listed in the »Finishes« block further down. From these we fabricate, as required, window sills (including special lengths in one piece up to approx. 3 m), interior stairs with treads and risers, washstand tops with an undermount cut-out, wall and column claddings, skirtings, benches and individual furniture tops. The high repeat accuracy is the real advantage in project business: many components in identical appearance, no sorting out caused by runs or bookmatching, and predictable re-production in the same colour tone.

Comparison. Natural Sivec marble looks brighter and livelier and shows the characteristic carbonate shimmer; the agglomerate remains more technical, more even and absorbs considerably less water, because the polyester matrix largely closes off the micropores. Compared with engineered quartz (CaesarStone, Silestone), the marble agglomerate stays visually closer to natural marble and mineralogically warmer, but because of the polyester content it is more sensitive to UV, high temperatures and strongly acidic cleaners. Compared with porcelain (Laminam, Geoluxe), the slab feels warmer and is less brittle, but is less resilient thermally and chemically.

Honest assessment. Micro Sivec does not replace solid Sivec marble in prestigious contract work. Its strength lies in a calm, calculable brightness, in the large format and in uncomplicated care in interior fit-out. Anyone who needs a homogeneous white-cream component for series fit-out, residential construction or repeatability in contract planning, and who does not expect individual marble veining, comes out cleanly with this material both economically and in design terms.
