Answer:
Use materials more resistant to chemical weathering.
Explanation:

Buildings made of brick and/or iron and steel will survive much longer in the elements in a tropical condition than will a building made of wood or calcite. The latter is especially vulnerable to even the slightest amount of acidity in the rain and is easily dissolved.
