Diy Concrete Brick

DIY concrete brick options are remarkably varied, ranging from those suitable for building walls to those that may be used to pave surfaces. DIY concrete brick options vary in colour and in texture. For example many units are smooth, but others are textured just like clay facebricks. Apart from the material used to make them, concrete bricks are pretty well the same as clay units, except that you won't find a DIY concrete brick that is suitable for use as a fire brick. The material simply doesn't withstand the heat of fire - whereas clay does, because it was baked in a hugely fierce fire in a kiln in the first place.

Concrete bricks (often referred to as cement bricks), on the other hand, are made in moulds, from a mixture of cement, sand and usually a very fine crushed stone aggregate and water. They cannot resist high temperatures and will quite simply crack if exposed to fire. So don't be tempted to use this type of unit to build a barbecue in your garden!

DIY Concrete Brick Choices

When you decide what to use for building, you always have a choice of unit (whatever it is made from) that may be left unplastered (or not rendered) and a unit that is laid and then left without any further finish. The latter is, of course, known as a facebrick, and it has a texture on one side (or face) that gives it a special character and charm. Plastering is more work, but then you will have the option of painting the finished surface, which adds colour and a different kind of character and charm.

Pavers are usually quite a bit thinner than building units, and because we walk on them, the surface is smooth. Many pavers are flat-sided, but the cement type are also moulded in shapes that will interlock one another, often in a zig-zag shape. These are ideal for driveways and steep slopes, and are often used for roads in housing estates.

In some parts of the world you will find paving units that are designed so that the corner of each block fits into the one next to it. This means that they can be laid so that grass or a ground cover of some type can grow between the units, which remain firmly interlocked. Hollow turf blocks have a similar effect although they are not a widely know form of DIY concrete brick.
