How Rain May Be Damaging Your Structure

Rain is a natural downpour of water hence it is uncontrollable and inevitable. However, rain water has continued to pose damages on building structures. These are quite prevalent in areas with low moisture capacitated soil. They are prone to invasion of water from rainfall which may eventually cause damage to the structure.

Areas with uneven topography can also suffer disadvantages of rainfall. Topography with interrupted flow of water will always have a centralized water log, in areas with poor drainage, intrusion of water is inevitable. There have been several dilapidations that have occurred from absorption of water in building structures. Though the effect may not seem spontaneous, but, it lurks and will surface with time. To avoid ignorance on how rain water eats the durability of building, it is needful to be educated on the methodology of these effects.

Effect on foundation: It is undoubtedly agreed that foundation is the most important part of a building. It carries the load of the superstructure. The durability of a foundation determines the durability of the structure on it. Soil types in terms of strength and moisture content is a determinant of the durability of a foundation. However, in areas with soil type of low moisture content, waters moving into the pores of such soil gradually causes threat to the durability of the foundation.

Effect on metallic parts: The entirety of building structure constitutes concrete reinforced with metallic materials. Corrosion occurs when these parts have contact with waters filtering through seepages and leakages. This corrosion which results in rusting of the metals, weakens the metals which are supposed to reinforce the concretes on the building. This corrosion causes decimation in the strength of the metal and by extension on the concrete.

Effect on concrete blocks: Concrete blocks are aggregates of materials with their varying grain and pore sizes. These buildings have a porosity that could absorb the torrential pour of rain. This absorption weakens the bonding strength of the constituents of concrete blocks. This also allows water seep into the internal facilities of the structure. Such case is water seeping through the wall of a building.

Effect of rain on roof

Effect on roof: This involves metallic and concrete roof. There are adverse effects in either. Metallic roof are susceptible to corrosion even when coated. Though, coated roofs hardly corrode, but leakages are caused by more factors like effect of the wind and expansion apart from corrosion. Leakages from the roofs affects the wooden and ceiling materials, also affects the interior of the building. Water settles on the roof causing discoloration on the ceiling materials. The settlement of water imposes tension on the roof, if continual, it may cause leakage or breakdown of the ceiling. Like the effect of water on concrete block, water leaks into the interior of the building from pores in the concrete roofs.

Growth of fungal: Rain water allows the budding of fungal organisms. These are the greenish grass-like plants seen on walls and floors of building with consistent engagement with water. These green coloration causes defacement to the building. More so, these fungal have adverse health effect on the inhabitants of a building. Hence, the health index of the occupants of a building is threatened by rain water through the breeding of fungal organisms.

These effects can be limited or eliminated with precautionary approach at the designing stage of the building. Professional project management may avert these adverse effects of rain water on your building.
