Case study: hydroiovation of two roofs with an area 1600 m2 using the Neoproof Polyurea R membrane

In the following case study, we look at the waterproofing of two roofs with a total area of ​​about 1600 m² . These objects were originally covered with bituminous roofing felt , but the investor decided on a modern and durable solution - a liquid waterproofing membrane Neoproof Polyurea R. Let's see step by step how the roof renovation process took place.

Preparation of the ground - cleanliness is the basis

The process began with thoroughly washing roofs with water under pressure , which was aimed at removing all impurities and preparing the surface for further work. A specialized cleaning agent was used in particularly dirty places .

Sealing of details and joints

The next stage was the thorough protection of critical places:

• Neotex PU Joint , flexible polyurethane mass, was used to seal the joints and to fix the lightning protection system.
• Chimney hats were painted twice with neoproof PU W-40 in brick color (RAL3009), providing them with protection against moisture and aesthetic appearance.

Strengthening the joints with polyester non -woven

After securing the details, the reinforcement of roofing felt and other sensitive points was started using the neotextile , It was embedded in mass by the "wet wet" method, and in the corners of the chimneys it was used with a tab - to increase tightness and durability.

Application of a liquid membrane Neoproof Polyurea R

After properly preparation of the surface, the appropriate membrane application began:

• The first layer was applied using the spray method evenly over the entire roof surface.
• The second layer was applied after about 10 hours (depending on the ambient temperature and ground). Importantly, the product can be applied not only by spray, but also with a brush or roller.

Fast hardening and resistance to weather conditions

One of the biggest advantages of Neoproof Polyurea R is its resistance to rain after 1 hour from the application . This is a huge advantage, especially with uncertain weather forecasts, which often complicate work related to waterproofing or renovation of roofing.

End result - a tight and durable surface

After completing the work, the roofs were covered with a uniform, flexible and in full -tight membrane , which not only protects against water, but also reduces the temperature on the roof surface and inside the building (the effect of the so -called "cold roof").

Summary

The above case study shows that the use of modern materials, such as the Neoproof Polyurea R , allows you to obtain long -term and effective protection of felt roofs. Thanks to the proper preparation of the substrate, careful sealing of details and a professional application, the investor has gained a solution that not only protects against leakage, but also increases the thermal comfort of the building.
