Common defects that occur in timber include knots, shakes, wind cracks, upsets, twisting, cupping, bowing, rot and insect damage. These defects are typically grouped into three categories: defects caused by natural forces, defects caused by defective seasoning and conversions and biological defects. There are various types of defects in timber as a construction material. These defects in timber can be due to natural forces, fungi, insects and during seasoning and conversion. Types of these defects in timber is discussed in detail. Trees gives us the timber which is converted into required form.  Defects in timber can affect its; strength, appearance, and durability.  Defects in timber are either; 1. Natural: defects that may be present in the growing tree. 1. Artificial: defects caused by the seasoning, conversion and felling process.
