MARISEAL SYSTEM® liquid polyurethane membrane system from Maris - a proven way to effectively waterproof various types of roofs
Due to the direct impact of atmospheric factors (rain, wind, sun or frost) and intensive use, such as in commercial buildings, the roof is one of the most vulnerable elements of the building structure. It therefore becomes a special challenge to properly protect the roofing, which will not only protect it from leaks, but also from mechanical damage.

With the help of liquid polyurethane membranes, we are able not only to make an effective waterproofing of the roofing, but also to create a tight, seamless membrane that can withstand even very heavy mechanical loads and, in addition, due to the high solar reflectance, effectively reduce the heating of the roof and the entire building structure.

Durable and reliable roof protection
Flat roofs, by virtue of their construction, require extremely effective protection against water, the drainage of which is much more difficult than in the case of sloping roofs. Therefore, the correct waterproofing of the roof becomes particularly important, which should go hand in hand with thermal resistance. Such high requirements for flat roofs make the so-called inverted roofs, in which waterproofing is laid directly on the substrate, which is usually a concrete floor, gain in popularity in recent years. Such a roof can also be turned into a so-called green roof, i.e. covered with plants and providing an additional place for comfortable relaxation. At the same time, it is worth noting that the inverted roof works well both for new construction and during the renovation of old flat roofs, as it allows to preserve the existing roof structure. Unlike a roof with traditional layering, it allows almost any use of the roof slope, without worrying about its damage or destruction, and additionally provides protection of the waterproofing layer from atmospheric factors (UV radiation, hail, etc.) and mechanical damage during subsequent stages of work or during the operation of the building. The key, however, is the proper waterproofing of the inverted roof, and this can be done with high-quality liquid polyurethane waterproofing systems.

"Unlike many other solutions available on the market, liquid roof membranes can be used not only on new, but also on renovated roofs, and both flat and sloping roofs. At the same time, they are great for roofs with limited load-bearing capacity, as they do not add any additional load to them. An example of such a product is Maris' solution, MARISEAL SYSTEM®, a high-tech liquid polyurethane waterproofing system that offers easy application, full certification and, most importantly, guaranteed long-term results. MARISEAL SYSTEM® consists of different products, depending on the characteristics of the roof, but each time it allows you to create a coating that is an effective protection against leaks and mechanical damage, which significantly extends the life of the roof. In addition, it can be applied directly over existing roofing materials, eliminating the need to remove them and the associated costs. In turn, the membrane's speed of setting makes the downtime of the roof very short, which is crucial if it is used commercially," explains Michal Bucik, Product Manager of SAINT-GOBAIN.

A way to lower bills
Resistance to extreme weather conditions or mechanical damage is one thing, but it's also worth remembering that when exposed to high temperatures, the roof surface is capable of reaching temperatures as high as 80°C. Much of this heat gets directly into the rooms, and this in turn can cause discomfort for the occupants, problems with concentration, fatigue, and even health consequences - pain and dizziness or fainting. It therefore becomes a challenge to ensure optimal indoor temperature, especially since this is one of the requirements imposed on employers by the current law. Some relief from the heat may be provided by the use of fans and air-conditioning units, but this is associated with high electricity bills, which are expected to become even more expensive due to the price unfreeze that has been in effect since July of this year. When designing a new roof or planning the renovation of existing sheathing, it is therefore worth eliminating the problem of heat transfer from the roof surface to the rooms. The solution may be liquid waterproofing applied to roofs, which reflects the sun's rays while lowering the temperature inside the building.

- One of the breakthrough solutions for effectively reducing the heating of roof surfaces is liquid polyurethane membranes. An example of such a product is the innovative COOL ROOF system from Maris. Thanks to the use of a unique 100% water-based polyurethane (with no added solvents) and various types of membranes and varnishes, it is able to effectively reflect sunlight(fraction of solar energy reflected from the roof at up to 89%) and increase thermal emission (ability of the roof to release absorbed heat up to 88%). This reduces the temperature inside the building (which increases the comfort of the occupants) and the energy consumption used by air-conditioning equipment," explains Michal Bucik, Product Manager of SAINT-GOBAIN.

Thanks to the use of state-of-the-art technologies, manufacturers of building products are able to provide solutions that not only respond to the growing demands of architects and investors, but also set new standards in the industry. This also applies to roof waterproofing - modern liquid polyurethane membranes not only provide effective protection for the roofing, but also allow additional benefits such as reducing the heating of buildings.
