Drywall, also called gypsum board or plasterboard, is a panel made primarily of gypsum plaster pressed between two sheets of thick paper, used to finish the interior walls and ceilings of most modern buildings. Drywall largely replaced traditional wet plaster wall construction over the course of the twentieth century because it installs much faster, requires

Formwork is the temporary mold, typically built from wood, steel, or engineered panel systems, that holds freshly placed concrete in its intended shape until the concrete cures and gains enough strength to support itself. Because concrete is placed as a wet, flowable material, formwork is essential to nearly all cast-in-place concrete construction, shaping everything from
The temporary mold that holds freshly placed concrete in shape until it cures and gains self-supporting strength.
Masonry is construction built up from individual units, such as brick, stone, or concrete block, bonded together with mortar into walls, arches, and other structural or decorative elements. It is among the oldest building methods in continuous use, with surviving examples of stone and mud-brick masonry dating back thousands of years, and it remains a
Construction built from individual units such as brick, stone, or concrete block bonded together with mortar.
Precast concrete is concrete that is cast and cured into finished structural or architectural components at a factory or dedicated casting yard before being transported to a construction site for assembly, rather than being poured and cured in place as part of the building itself. The approach reverses the usual sequence of concrete construction: instead
Concrete cast and cured into finished structural components at a factory before being transported to a site for assembly.
Prefabrication is the practice of manufacturing building components, or in some cases entire building modules, at a factory before transporting them to a construction site for final assembly, rather than constructing every element from raw materials on site. It spans a wide spectrum of complexity, from simple prefabricated roof trusses and wall panels assembled on
The manufacturing of building components or complete modules at a factory before transport to a construction site for assembly.
Rebar, short for reinforcing bar, is steel rod, typically manufactured with a ribbed or deformed surface pattern, embedded within concrete to provide tensile strength that plain concrete lacks on its own. Concrete is strong in compression, resisting crushing forces well, but weak in tension, cracking relatively easily when pulled or bent, so reinforced concrete pairs
Steel rod embedded in concrete to provide the tensile strength that plain concrete lacks.
Scaffolding is a temporary structure built to support workers, tools, and materials at elevated heights during construction, maintenance, repair, or demolition work, providing a stable platform where no permanent floor or working surface yet exists. Scaffolding ranges from simple frames assembled from standardized tube-and-coupler or frame components to complex engineered systems designed for tall buildings,
A temporary structure built to support workers, tools, and materials at elevated heights during construction.
Structural steel is steel fabricated into specific shapes, such as beams, columns, and trusses, and used as the primary load-bearing frame of a building or other structure. Valued for its high strength relative to weight, consistency as a manufactured material, and suitability for prefabrication, structural steel has been a dominant framing material for mid- and
Steel fabricated into beams, columns, and other shapes used as the primary load-bearing frame of a building.
Timber framing is a construction method that builds a structure’s skeleton from large, solid wooden beams and posts joined together, traditionally using carved mortise-and-tenon joints secured with wooden pegs rather than metal fasteners. It predates industrial nails and bolts by centuries and produces a visually distinctive structure, often left exposed both inside and outside the
A construction method that builds a structural skeleton from large wooden beams and posts joined with carved joinery.
Waterproofing is the application of materials and systems designed to prevent water from penetrating a building structure, protecting foundations, roofs, walls, and other building elements from moisture intrusion that can cause structural damage, mold growth, and deterioration of finishes over time. Waterproofing differs from water-resistant construction in that it aims to create a continuous, impermeable
