Malta Business Review BUILDING & CONSTRUCTION AFTER THE STORM COMES THE CALM Application of seamless resin membrane with fibreglass netting Finished roof The heavy rainstorm has finally stopped. Or maybe a long winter has finally ended. While good weather may seem like a relief, the potential for water damage may just be the beginning. Storm water runoff can quickly overwhelm natural and manmade systems, leading to flooding and property damage. The most common damage from a storm is to roofing and retaining walls, which often results in water leakage that leads to interior water damage and possible mould. By Antoine Bonello For homes that are connected, or semidetached, damages on the roof or within the walls can also cross property lines. In a natural environment, storm water runoff is absorbed by soil and vegetation, evaporates into the atmosphere or flows into bodies of water. Urban development has dramatically changed this natural system. Rainfall is nowadays directed rapidly by roofs and roads into pipes and channels leading into wells or other water storage facilities. Storms are one of the most common causes of roofing leaks. Water can enter your home from various areas and you need to be vigilant before a minor leak gets bigger. Many damages are the result of poor DIY works or the use of low quality materials that do not withstand climate change and structural movements. The help of qualified experts in these situations is of utmost importance. Only a qualified roofer can provide you with a tailor made waterproofing system that suits your needs. The steps you take today to prepare your home and terraces with proper waterproofing and appropriate drainage system can help you avoid time-consuming and costly repairs when the bad weather does blow through. The good news is that there are products and techniques that can withstand UV rays, high winds, sea salt corrosion and water stagnation and can save you the ordeal or constant maintenance and vigilance. How Can You Protect Your Home from Storm Water? Most of the water intake from retaining walls are simply related to the use of nonelastic and non UV resistant paint that becomes rigid and starts to flake and peels off when subjected to Sun rays and building movements. An easy way to avoid these types of problems is by using a certified UV Resistant and Elastic waterproof paint. These certifications must be clearly shown on the cans and are usually found only on CE certified products. If in doubt consult the product data sheet that nowadays are easily available on the internet. The application is important as the product itself, we tend to believe that two coats of product is sufficient to withstand our Mediterranean climate and in many cases the primer is left out. For optimal results the application of a consolidating primer is required to strengthen the sand and cement plastering, together with a minimum of three coats of product for an average consumption of 500g-1kg per square metre. Roofs are no exception and before we apply any form of protection we have to put into the equation many factors such as its size, the location (by the sea or inland) and its use (BBQ and leisure). Salt, wind and hail can easily damage plastic/ acrylic based membranes, while traditional carpet bitumen membranes and cement based membranes are too rigid and fail very easily when subject to structural movements. Resins membranes on the other hand are proving to be the future; they are designed to meet our harsh hot summer and sudden climate change. Their application is simply by roller, brush or sprayed and can be applied easily in corners and obstructed areas. The final result is completely seamless, elastic, resistant to heavy traffic, can withstand direct bonding of tiles if desired and guaranteed to last for years due to their resistance to UV rays. They are light in weight compared to other materials and can become stronger when they are 54

BUILDING & CONSTRUCTION Malta Business Review Structural damage because on inapropriate waterproofing retaining walls treated with a UV resistant elastic resin that waterproofs and stops heat intake inside buildings reinforced with fibreglass net type matt 225. Resin membranes also help to reduce heat intake inside buildings due to their thermal ability to reflect natural radiation. We all know that delicate works that involve waterproofing must be carried out by professionals who are able to identify the problems and address them with the best possible materials and solutions possible. The problem is how to identify the good installers from bad ones. The answer is simple, always make sure that the roofers are members of the Malta Professional Waterproofing and Resin Flooring Association. This guarantees good work, traceability and trustworthiness. Serious roofers are in possession of the Association’s Installers Card for the peace of mind of their customers. Always ask the roofer if he is a member of the said association and to show you the Installers card prior to any works.
