Most houses in Ireland are built of concrete. Here are some of the materials that are used to build a house or a school like yours.


A building block is made by mixing water, sand, stone and cement. This mixture is called concrete.

The blocklayer uses blocks to build walls like the ones in the picture. Concrete is also used for the foundations, which are the first part of a house to be built and which make sure the house lasts for a long time.


Plaster is a mixture of lime, sand and water. (Lime is found in the ground).

Plaster is used to coat walls and ceilings, like the walls in the picture and it makes the walls waterproof.

When the plaster dries out, it can be painted.
