A fresh set every day. Short, practical, and written the way it actually matters on site.
Dead Load
The permanent self-weight of the structure and its fixed finishes.
On siteIt never goes away, so it dominates long-term deflection and creep.
Segregation
Separation of coarse aggregate from the mortar paste in fresh concrete.
On siteUsually caused by dropping concrete from height or over-vibrating. Leaves honeycombed, weak pockets.
Permeability
How readily water flows through a soil mass.
On siteDecides whether an excavation needs dewatering and how fast a clay layer will consolidate.
Contour Line
A line joining points of equal elevation on a plan.
On siteClosely spaced lines mean steep ground. Reading the spacing tells you the earthwork before any calculation.
Sunken Slab
A slab cast lower than the surrounding floor, usually in wet areas.
On siteIt hides the drainage run below finished floor level. Waterproofing the sunken portion is what actually matters.
