BASIC TECHNOLOGY LESSON NOTE: Building Construction - Walls and Floors

Wall and floors
Walls of traditional buildings like huts are made from mud, grass and timber, while walls of modern buildings like duplex are made from bricks.
Walls are reinforced to make them stronger.

What do walls  provide to buildings?
1.    Strengthen and stability;
2.    Protection against weather conditions and external danger;
3.    Durability;
4.    Fire protection; and
5.    Sound control as in a theatre, music studio or big assembly place.

Materials for making traditional houses
1.    Mud
2.    Clay
3.    Laterite
4.    Grass
5.    Leaves
6.    Corrugated iron sheets
7.    Sawn timber

8.    Water

Materials for making modern houses
blocks and reinforcement rods used in building
Sawn timber 
2.    Clay
3.    Laterite
4.    Cement
5.    Gravel
6.    Corrugated iron sheets
7.    Asbestos

8.    Granite
9.    Water
10.  Plywood
11.  Veneer
12.  Aluminium
13.  Chrome
14.  Damp Proof Membrane
15.  Damp Proof Course.

The two classes of modern walls:

1.    Load bearing wall: this carries its own weight and the weight of the materials put on it, e.g. roof and floor slab.

2.    Non-load bearing wall: this carries no load, but serves the purpose of partitioning, protection and beautification, e.g. fence and partitioning walls.

1.    List 7 common types of walls
2.    What is DPC?
3.    List the functions of the DPC.


Floors carry the load in a building. The two main types of floors are concrete and timber floors. 

Timber floors are cheap and durable. They make the building cool. But they are not as durable as concrete floors.

Concrete floors are widely used today. They are strong, solid and last longer. Concrete floors may be reinforced with iron rods.
