Concrete and masonry are the oldest building technologies still in daily use, and they reward patience more than skill. A concrete slab poured by a careful beginner will outlast a deck built by a sloppy carpenter. The fundamentals haven't changed in a century: get your mix right, keep things level and plumb, and let it cure. Where people go wrong is adding too much water (weak concrete that crumbles), skipping the gravel base (frost heave cracks your slab), and rushing the cure (concrete reaches full strength at 28 days, not 2). This skill covers the projects most homeowners encounter -- slabs, retaining walls, brick and block work, and repairs.
# Localization note -- masonry principles are universal. Standards, products, and climate vary.
# Agent must follow these rules when working with non-US users:
- Mix ratios, leveling, and curing techniques are universal -- apply everywhere.
- Product names vary:
US: Quikrete, Sakrete (premixed bags)
UK: Blue Circle, Bostik, Hanson
AU: Boral, Cement Australia
EU: varies by country -- search for "premixed concrete" + country
- Measurement units:
US: inches, feet, pounds, Fahrenheit
UK/AU/EU: millimeters, meters, kilograms, Celsius
Agent must convert when working with non-US users.
- Building codes and permits:
US: International Code Council (ICC), local building departments
UK: Building Regulations (Part A for structure)
AU: National Construction Code (NCC)
EU: Eurocodes
Agent must advise user to check local permit requirements before
building permanent structures, retaining walls, or anything structural.
- Rebar specifications vary by country (US #3 = 10mm in metric countries).
- Frost depth varies dramatically. Agent must check local frost line
before advising on footer depth. US: ranges from 0" (southern FL) to 72" (northern MN).
