Among other building work at the Basílica de la Sagrada Familia waterproofing is currently underway on various roofs and exposed areas. In this article we will describe some of these procedures. 

In the case which concerns us swift waterproofing was required to ensure the watertightness of one of the basilica’s concrete roofs. It was decide to employ a solution using a continuous membrane of DESMOPOL polyurethane.

As we always recommend for this type of application, correct surface preparation is essential to guarantee optimum adherence to the surface membrane. On this occasion a mechanical blasting was employed in order to obtain a regular and smooth surface which would allow the correct attachment of the waterproofing system to the surface.    

All the individual points were then sealed: joins, corners, folds etc., using PRIMER EP-1020 epoxy resin mortar, and MASTIC PU polyurethane putty, reinforcing these seals with TECNOBAND 100 self-adhesive geotextiles strips.

The entire surface was then primed by the application of a mineral bonding layer consisting of PRIMER EPw-1070 epoxy resin, which was followed by a DESMOPOL polyurethane continuous membrane, with added DESMOPLUS to increase resistance to breakage and reduce curing time.  

Lastly, two layers of TECNOTOP 2C aliphatic polyurethane will be applied with a sprinkling of aggregate, to obtain a surface resistant to UV rays, and at the same time rugged with anti-slip properties.
