= Introduction =

All building materials can suffer from deterioration and decay if they are not protected or maintained correctly. Some common scenarios that can lead to the degradation of construction materials are:

* Natural agents.
* Moisture.
* Shrinkage.
* Exposure conditions.
* Corrosion in metals.
* Loading.
* Chemical.

Some measures can be put in place to minimise early degradation of materials

= Timber =

Timber can deteriorate due to various circumstances. Timber is especially susceptible to wet and dry rot, woodworm and shrinkage.

Wet and dry rot

* Address any signs of damp.
* Apply timber with anti-fungal treatment.
* Ensure areas have good ventilation.
* Apply external applications of paint that excludes moisture.
* Remove and replace any infected timber areas.

Woodworm

* Apply insecticide treatment.
* Address any signs of damp.
* Ensure areas have good ventilation
* Remove and replace any weakened timber

Shrinkage

* To minimise shrinkage of timber, allow it to acclimatise to the conditions before installation.

= Stonework =

Stonework can be susceptible to deterioration from acid rain. To minimise the decay the following measures can be implemented:

* Apply specialist treatment.
* Remove and replace damaged stones.

= Concrete =

Concrete is susceptible to sulfate attacks. To minimise the damage the following steps can be taken:

* Address any signs of damp
* Apply sulphite-resistant cement.

= Polymers =

Polymers like uPVC are easily damaged by exposure to UV light. In sunlit exposed areas it is advisable to use polymers that have a UV-inhibiting additive.

= Steel =

Corrosion is the main contributing factor to the degradation of steel. The following steps can be taken to minimise rust:

* Galvanising which consists of a hot-dip zinc coating.
* Painting which excludes moisture.
* Stainless steel can be used for areas exposed to high moisture content.

= General =

Additional scenarios that can lead to degradation in all materials is stresses from loading forces. Materials should be designed by taking into consideration their strength and weaknesses and the maximum loading and bearing capacities of their structures.
