pedreiro

Pedreiro is a skilled tradesperson who works in masonry, constructing and repairing structures using bricks, concrete blocks, stone or poured concrete. In Portuguese-speaking countries such as Portugal and Brazil, pedreiros build walls and façades, foundations, columns, arches, and perform related tasks such as plastering and pointing.

Typical duties include reading plans and specifications, preparing mortar, mixing cement with sand and water, laying units in specific bonding patterns, shaping and cutting materials, applying plaster or stucco, rendering joints, and ensuring proper alignment, plumb, and level. In structural work, they may install lintels, reinforce masonry with steel, and set forms for concrete.

Training is usually through vocational schools, apprenticeships, or on‑the‑job learning. Certification and licensing vary by country or region. Safety training is a core component, with emphasis on fall protection, handling of heavy materials, dust control, and use of personal protective equipment.

Common tools and materials include trowels, pointing trowels, mason's hammers, levels, plumb lines, chisels, hods, wheelbarrows, mixers, and scaffolding; and materials such as bricks, concrete blocks, cement, sand, and mortar. Pedreiros work in construction, renovation, and industrial settings, and may be employed by contractors or operate independently as experienced masons.

Etymology: the term derives from pedra, stone, with the agentive suffix -eiro, indicating a person who works with stone or masonry. The role varies by region but generally refers to a mason or bricklayer and is a fundamental building trade worldwide.
