It consists of the waterproofing of the perimeter walls of service zones in the main control tower building of Marina. it was applied in those areas , pure polyurea membrane tecnocoat P-2049 as a barrier against rain water infiltration getting into the interior of the offices. It was waterproofed approximately 800 m2 with P-2049 Tecnocoat continuous membrane 100% pure polyurea on steel tole.

The procedure followed in this application is as follows: 
  
First step:  support preparation
  • Milling of the surface:  surfacing of the concrete slab, to obtain a high  adhesion of the system and reducing at zero the accumulation of air and therefore the appearance of bubbles or craters in the surface once the membrane is applied. 
  • General Cleaning: removing with vacuum of dust, dirt and other material generated during earlier work and that may prevent optimal adhesion to the substrate. 
 
Second step: singular points 
  • They are the elements as dilatation joints, encounters with walls, drains or other specific and singular points of the structure and surfaces. They require focused work to ensure proper system operation. In this case, the work was done in the following points. 
  • Preparation of existing joints: joints on existing slabs and perimeter walls were prepared using our Desmopol PU elastic sealant (mastic), to achieve a perfect flexibility and prevent breakage due during possible excessive movement of the concrete structure..
 
Third step: Tecnocoat P-2049 application
The Tecnocoat P-2049 system used on this project is constituted by: 
  • Primer Tecnocoat Primer PU: applied with a roller over the entire surface, improves the adhesion of the existing support and avoid the presence of trapped air. 
  • Membrane  Tecnocoat P-2049: Tecnocoat polyurea membrane 100% pure, continuous and fully bonded to the support, is applied by spraying equipment as graco E-XP2, by an instantly control of mixture,  temperature and pressure of the liquid components. It is applied directly on the primer, in many continuous layers until the thickness required by our document ETA 11/0357.
 
APPLICATION’S ADVANTAGES  
The factors favoring the application of the Tecnocoat P-2049 system, and not other coating systems 
were as follows: 
  • High resistance of membrane against aggressive environment and atmospheric agents. Mostly corrosion and oxidation. 
  • Great coating membrane, and excellent attachment on the metal element of structure 
  • Complete continuity of the coating membrane, fully adhered, without joints or overlapping for all the execution.
