Waterproofing Solutions for UV Resistant Terrace Flat Roofs

Surface Preparation

The reinforced concrete application surface should be checked before waterproofing. The surface is free of residues that will prevent adhesion, clean, smooth and sound. The roof terrace slope should be designed as min 2%. Waterproofing system with protection and supporting layers (if any); should be able to withstand the effects of roof slope. The points (sieves and pipes) where the water onto the roof terrace to be discharged should be determined according to the roof area and annual rainfall quantity of the area where the application is made. Reinforced concrete surface should be properly levelled for homogeneous application of the waterproofing product. If there are defects on the application sub-surface, it should be repaired with 4002 Tamirart 30 thick repair mortar. If there are structural cracks on the surface, 4004 Tamirart S40 should be used. Waterproofing should be ensured by using 4004 Tamirart S40 repair mortar on inner corners for sustaining the sealing. 4505 Kalekim Astar (Primer) should be applied after surface preparation.


Waterproofing Application

3027 Izolatex UV, which is a white coloured, cement based, UV ray resistant, two component, waterproofing material should be applied in primed, reinforced concrete surfaces where pre-application preparations have completed for balconies and terraces. Existing floor wall and corner joints should be reinforced with Kalekim Waterproofing Tape (Type III). The tape should be installed carefully on the waterproofing material, the first layer of which has been applied with a brush or a roller, in a way that the center of the tape matches with the joint.

The second layer should be applied after waiting for 5-6 hours between layer application depending on the ambient temperature. After the surface dries, it should be waited for 7 days for full setting and leak-tightness tests should be carried out for 24 hours. A long-lasting and secure waterproofing resistant to sunlight is ensured without any cover-up by using 3027 Izolatex UV applied as 2 layers on the terraces.
