Renovation of flat roofs and terraces


rehabilitacion cubierta teja

The renovation of older flat roofs requires effective and hard wearing solutions. TECNOPOL continuous systems provide excellent results without the need to remove the existing paving or flooring surface. In addition, the nature of these finishes makes them ideal for use on older roofs which are hardly ever perfectly smooth or flat.

Where the renovation also requires thermal insulation we can provide one of the best systems on the market providing optimum results in terms of low heat conductivity.

SYSTEMS DETAILS

Flat roof renovation

rehabilitacion cubierta teja

1 Surface preparation

Initially the floor will need to be cleaned down to remove all traces of the previous waterproofing material or loose pieces, and cracks and joins should be filled or repaired to ensure as flat a surface as possible.

2 Primer

First apply a coat of primer resin to ensure maximum adhesion to the surface.

3 Waterproofing membrane

Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used. In the event of applying the DESMOPOL system on ceramic or brick surfaces it is recommended that the DESMOPLUS 1 LAYER additive is employed to make the membrane more resistant.

4 Finish layer

The TECNOPOL finishing coat consists of an aliphatic resin, highly resistant to UV rays and hard wearing (can be walked on), and to which an anti-slip finish may also be added (conforms to CTE DB SUA, Class 3 classification (Rd >45), according to UNE-ENV 12633:2003). TECNOTOP can also be supplied in practically any colour.

Transparent finish for the renovation of flat roof surfaces

1 Suport preparation

Initially the floor will need to be cleaned down to remove all traces of the previous waterproofing material or loose pieces, and cracks and joins should be filled or repaired to ensure as flat a surface as possible. It is also important to provide a clean and aesthetic appearance as the coats we will then apply are completely transparent. .

2 Primer

An adhesion promoter will then be applied to ensure proper adherence to the surface.
