bricklay
To lay brick; to use mortar to construct a structure using bricks.
bricklay: the verb form of bricklaying, now archaic
To bricklay means to lay bricks in mortar, building up walls, chimneys, pavements, or other masonry structures one unit at a time. The term is the infinitive or base form of the action, though modern workers and foremen almost always say lay bricks or use the gerund bricklaying instead. You will encounter bricklay mostly in older technical writing, contracts, or British sources, where it persists as a formal verb despite having fallen out of daily speech.
The work itself involves spreading a bed of mortar (usually a 1:3 or 1:4 cement-to-sand ratio by volume) on the course below, pressing each brick firmly into place, filling the joints between units, and striking them flush or recessed as the specification demands. A skilled layer works to line, level, and plumb while maintaining bond patterns such as Flemish, English, or stretcher bond. The mortar must have the right consistency: too dry and the brick won't seat properly; too wet and the wall will slump and the joints will squeeze out.
Why the term survives where it matters
Historical contracts and building codes often retain bricklay as the formal verb because it appears in legislation, specifications, and precedent documents that remain in force. A clause written in 1950 may still refer to bricklaying work or the verb form to bricklay, and because legal and regulatory language resists change, the term endures in those contexts even as tradespeople themselves use simpler phrasing.
In estimating and scheduling, the rate of bricklaying is typically measured in units per hour or per day: a competent bricklayer in good conditions will lay between 300 and 600 bricks per day depending on wall type, mortar quality, weather, and access. This productivity metric drives job costing and crew planning, making precision in describing the work important for contracts, even if the verb itself sounds old-fashioned on a jobsite.
