The single most important element in a roof is protecting the integrity and the structural components on the roof. For this reason, there must be a waterproofing system with exceptional longevity to prevent damage and to reduce the possibility of long-term expensive reconstruction.
The roof of a building is the most affected part, directly impacted by ingress of water through rains. The leakage from the terrace or roof slab causes serious damages to the structure through seepage. The dampness inside the structure that results due to seepage, damages the interiors and creates hygiene problems. Excess moisture leads to growth of microbes, such as mould, fungi and bacteria in the interiors of the structure.
The main criteria for selection of a waterproofing material in roofs are Integrity and durability of the weather proofing material and performance. Flat roof finishes are the most vulnerable due to low movement tolerance to the drains. Roof are often complicated structures with many Plumbing and HVAC installations at the roof, so the waterproofing material should be suitable to meet all these critical needs.
The repair or waterproofing restoration on many old roofs are often limit the types of waterproofing system that can be used. The repair & restoration by conventional waterproofing technologies add up the dead load of the roof slab with the protection layers. A removal of old protection layer & waterproofing materials challenges the structural integrity.
That is why ALCHIMICA has developed exclusive waterproofing solutions for both EXPOSED and NON-EXPOSED applications.
