Façade cracks, hairline or wider, linear or angular, structural or otherwise can be a strain aesthetically as well as environmentally. In the dry season (hot or cold) it results in increased discomfort and enhanced HVAC cost. In wet season it comes knocking leaving wet patches all around which lead to growth of fungus. These things need to be ascertained by an expert in Waterproofing Services .
In special cases it can also lead to inviting Mr.Leak creating puddles in the structure within. https://www.youtube.com/watch?v=Nz6WBT6hyUY
The cracks appear for various reasons:
1. In case of new construction due to faulty construction practices, either material or workmanship or both.
2. In case of older structures due to gradual neglect and ageing.
The hairline cracks up to a maximum of 5 mm can be restored with crack seal compounds or putty, followed by protective coat to match the surrounding surfaces.
The wider cracks need to be assessed for causes beyond the skin and provide corrective treatments and finally seal using PU sealants or other corresponding products as per availability.
In case of structural cracks the strengthening of the structural members involving industry best practices is vital. Proper tests should precede any treatment involving an expert waterproofing contractor/consultant .
A healthy building is invariably free of cracks (other than fine shrinkage cracks), and shines as it can retain its sheen without having to stain itself due to weathering conditions. A crack free façade prevents expenses incurred to maintain the interiors, reduces energy costs and finally reduce the cost of external facade restoration, resulting in a healthy, shinning façade for years to come.
