Capabilities
Every surface, one contractor.
Sigma carries a project from material selection through field installation, so you coordinate stone, tile, and terrazzo with a single accountable team.
Marble & Stone
Natural stone installation for lobbies, suites, and public spaces, from slab selection in quarries abroad to precision field installation.
Tile
Ceramic, porcelain, and specialty tile at any scale, including pioneering thin-format porcelain on vertical surfaces.
Terrazzo
Sigma Terrazzo delivers microcrete floors, custom stair treads, and terrazzo systems for corporate campuses and civic spaces.
Design & Drafting
In-house drafting, shop drawings, and design support so architects and builders stay aligned from pre-construction through turnover.
Fabrication
On-site and shop fabrication at our Dallas facility: countertops, vanities, CNC-cut slabs, and custom stone elements aligned to your schedule.
Material Procurement
We work directly with builders, architects, and designers to source materials globally and manage delivery to the job site.
The Process
A clear path from drawing to done.
We've run it on jobs like Raymond James Stadium 60,000 SF in ten weeks, and the Gaylord Texan, with stone sourced across continents.
Pre-construction
We join early, reviewing drawings, advising on materials, and producing shop drawings so the design intent holds from day one.
Procurement
We source globally and inspect at the quarry, photographing slabs for approval before a single block ships.
Fabrication
CNC cutting, edge profiling, and terrazzo at our Dallas shop, built to your drawings and your schedule.
Installation
Field teams install to tolerance on the most aggressive calendars in commercial construction.
