Waterproofing old concrete roofs and terraces is critical for ensuring structural integrity, safety, and longevity. They are among the structures most prone to water damage. Older roofs are subjected to years and sometimes decades of environmental exposure to such as sun, rain, and wind. Hence, it is even more important to implement concrete waterproofing measures. But what is the best way to do it?
This blog will discuss the signs that your old roof needs waterproofing, different types of concrete waterproofing methods, and our best solutions. But first, you need to know why waterproofing is essential for old roofs.
Roofs are constantly exposed to extreme weather conditions like heavy rains and harsh sunlight, weakening their structural integrity. In older roofs, these conditions can lead to cracks, leaks, and general deterioration. When water seeps into these cracks, it can corrode the iron bars, expand the concrete inside, and damage the interior, including ceilings and walls.
Concrete waterproofing helps maintain the integrity of the roof by preventing water from getting through the cracks or tiny pores. This not only extends the longevity of the structure but also maintains safety, as water-damaged roofs are at risk of collapsing. Old roofs that have been water-damaged also look very dull and shabby. Waterproofing can help to reverse this and improve the structure’s aesthetics.
Visible Leaks: Visible leaks are a clear sign that water is penetrating the roof. If you notice water dripping through the ceiling or spots forming during rain, it’s time to address the waterproofing to prevent further damage.
Water Stains: Water stains on the ceiling or walls indicate past water intrusion. These stains can worsen over time, leading to structural damage and potential mould growth.
Dampness: Poor drainage and moisture trappings can deteriorate the concrete by causing dampness. Damp spots on your ceiling and walls are often the first sign of moisture seeping through the roof.
Mould Growth: Where there is moisture and dampness, mould will follow. Mould growth can compromise indoor air quality and cause structural damage if left untreated.
Peeling Paint: When water seeps through an old or damaged roof, it can cause interior and exterior paint to bubble, crack, or peel. You will also notice wood rot and patches.
Cracks or Gaps in the Roof Material: Over time, roofing materials like shingles, tiles, or metal sheets can develop cracks or gaps due to age, weather exposure, and natural wear and tear. These openings allow water to seep in, leading to leaks and structural damage.
As one of the best construction chemical manufacturers in India, we offer a range of waterproofing solutions, such as:
Mcon Magic Coat 2K: Magic Coat 2K is the perfect solution for sealing cracks and gaps. It accommodates cracks up to 2 mm with an elasticity of 40-50% while providing resistance to water.
Mcon Damp Lock: Magic Damp Lock is a fibre-reinforced waterproofing membrane that offers excellent protection against rain and harsh sunlight. Upon curing, it forms a thick, seamless, durable membrane, which offers ultimate waterproofing.
Mcon Magic Coat Flexi: Magic Coat Flexi is a very popular cement waterproofing solution for terrace gardens and bathroom floors. In addition to waterproofing, it provides excellent resistance to heat and chemicals.
Mcon Magic Coat PU Antiroot: Magic Coat PU Antiroot is a cold-applied waterproof membrane that cures to a rubber state. It can withstand oxidation and ozone and is resistant to peeling and chipping. It offers an elongation of 400%, meaning it can stretch to four times its original length before breaking.
Old roofs are often subjected to years of weathering, making them prone to leaks and cracks. Hence, to protect the structure and maintain safety, periodic waterproofing is essential. By identifying early signs of water damage, you can effectively protect your roof from further deterioration. There are various types of concrete waterproofing methods to choose from according to your needs.
