When rectifying leakages of roofs and balconies, the assessment of the area is one of the most important steps. Identifying the sources of leakage is essential as it will help in subsequent treatment over the roof slab. Once the sources of water leakages have been identified, the next step in assessment of the roof slab is checking for the slope of the roof.
Checking the floor screed for cracks and hollow sounds is also essential. If the floor screed has many cracks, they should be rectified using an appropriate crack filler from the Crack Heal range of Ressichem Products. Usually, Crack heal 920 2K is a suitable crack filler. If there are hollow sounds over the slab and the screed has been deboned from the RCC slab, it is recommended to remove the old screed and relay it in a slope going towards a proper water drain. It is recommended to add Ressi SBR 5850 and Silmix into the screed mix. It is recommended to add 1 Ltr of Ressi SBR 5850 and 1 Ltr of Silmix into every bag of cement used for making the mix of the floor screed. If water drains are not properly laid out, it is recommended to lay the proper water drains as well.
