Building Materials Guide

Cement binds every concrete and mortar mix, and the correct type depends on the soil and water conditions of the site. The wrong choice quietly shortens a structure's service life.

Rebar carries the tensile forces concrete cannot. Substituting a different grade or diameter on site changes how the frame behaves in an earthquake.

Ready-mix is far more consistent than site-batched concrete, but final quality still rests on transport, placing and curing. The drawings set the class, not the contractor.

Lightweight blocks cut dead load and improve the thermal performance of walls. They are non-load-bearing and must be properly tied back to the frame.

Clay brick still holds its place in both masonry walls and facades. Firing quality and water absorption are the two decisive selection criteria.

Waterproofing is the line between a sound building and a damp one. Most damp problems trace back to poor installation rather than poor membrane quality.

Thermal insulation cuts heating and cooling costs and is mandatory under Part 19. Continuity of installation matters more than sheer thickness.

Stone cladding is both the face of a building and its first defence against rain and sun. At height, the fixing method is a safety matter, not a question of taste.

UPVC windows with double glazing noticeably reduce heat loss and noise ingress. The decisive factors are profile quality and the steel reinforcement inside it.

Gypsum and soil plaster forms the base coat of interior walls and sets the flatness of the finished surface. Its rapid set makes quality heavily dependent on the crew's skill.

Tile provides a washable, durable surface for floors and walls. Selection should follow water absorption, abrasion and slip resistance rather than pattern alone.

Paint is the last visible layer of a building and, on facades, a protective coating. Its life depends far more on substrate preparation than on the price of the tin.
