Granite Fabrication Labor

Job Description

Job Description

n stone and granite fabrication shops, the "pour room" (or casting/epoxy area) is where workers stabilize, reinforce, and repair natural stone slabs. Because natural materials like granite, quartzite, and marble often feature natural fissures, voids, or fragile backings, a Pour Room Technician uses specialized resins, epoxies, and fiberglass mesh to make the stone structurally sound before it is cut by the bridge saw or CNC machines.

Job Description: Pour Room Technician (Stone Fabrication)

Position Overview
The Pour Room Technician is responsible for the structural reinforcement, flaw repair, and stabilization of natural and engineered stone slabs. Working in the casting/pour room, this role involves applying fiberglass mesh netting, pouring specialized epoxy resins into stone voids, and treating fragile materials (like quartzite and exotic granites) to ensure they do not crack or break during the cutting and polishing phases. 

Core Duties & Responsibilities

• • Slab Inspection: Examine incoming stone slabs for structural integrity, mapping out natural fissures, pits, cracks, and fragile veins that require epoxy filling. 
  • Fiberglass Mesh Backing: Apply fiberglass mesh and resin to the back of fragile slabs to provide critical structural reinforcement for safe handling and fabrication.
  • Resin & Epoxy Pouring: Mix, tint, and pour specialized epoxy or polyester resins to fill voids, pits, and open fissures on the face of the stone, matching the color and pattern of the natural slab. 
  • Chemical Blending: Accurately measure and mix multi-part chemical compounds (resins, hardeners, accelerators, and color pigments) according to specific environmental and stone-type requirements.
  • Curing Management: Prepare slabs for the curing process, safely managing the shop's specialized curing tables, vacuum tables, or multi-tier slab racks.
  • Surface Pre-Scraping: Use hand tools, razors, or light grinders to scrape away excess cured resin from the slab face, preparing a flat surface for the polishing department. 
  • Material Handling & Safety: Safely operate overhead cranes, vacuum lifters, and forklifts to move massive, heavy stone slabs into and out of the pour room. 
  • Inventory & Maintenance: Maintain a clean workspace, manage chemical inventory shelf-life, and meticulously clean pouring tools, mixing buckets, and safety equipment.

Qualifications & Skills

• • Experience: 1+ years of experience in stone fabrication, auto-body repair, concrete finishing, or a manufacturing role involving multi-part epoxies and resins is preferred (though many shops provide on-the-job apprenticeship training).
  • Attention to Detail: Excellent color matching ability to blend pigments seamlessly into natural stone variations.
  • Technical Savvy: Understanding of chemical cure times, temperature sensitivities, and safety data sheets (SDS).
  • Physical Stamina: Ability to stand for prolonged periods and safely push, pull, or lift heavy materials (frequently up to 50–75 lbs).
  • Equipment Knowledge: Prior experience operating overhead bridge cranes, vacuum suction lifters, or forklifts is a major plus. 

Working Environment & PPE Requirements

• • Environment: Exposed to dust, stone particles, and strong chemical fumes from resins and hardeners. The environment can be loud and non-temperature-controlled.
  • Mandatory PPE: Must wear a respirator or heavy-filtration mask, safety glasses, steel-toed boots, protective gloves, and aprons.
