ISOPROOF SEALER Providing waterproof treatment to roof slab using 2 coats of acrylic co polymer elastomeric ISOPROOF sealer & protector. The surface shall be prepared free of tar, dust, fungus, loose particles etc.,The surface shall be applied with basecoat of crystallization liquid and then ISOPROOF, wetting agent and liquid (1:1:6) over the prepared surface. In addition the surface shall be provided with polysulphide/ acrylic sealant to V groves, making haunch at junction of parapet and roof slab and at damaged portion using patching mortar to drain off rain water. Over this one coat of flexible cementatious membrane (FCM), Spreading 2 layers of 40 gsm non woven geotextile membrane as reinforcing material (over FCM) with one primer coat of ISOPROOF & applying second coat of ISOPROOF liquid over the primer coat - conforming to ASTM D 412 - 1992. The work shall be carried out as per the directions of the Engineer in charge. standards & methodology : 1. surface Preparation The surface shall be made free from all dirt, fungus, loose particles by using wire brush. The surface shall be cleaned with solvent like xylene, Toluene, Benzene, dilute hydro chloric acid. i) Cutting of ‘V’-Grooves : The V shaped grooves shall be cut along the location of all the visible cracks. The ‘V’-Grooves shall be of size 5mm as directed by the Engineer in charge. 2. Primary reduction of water permeability The concentrated crystallization liquid of specific gravity 1.09 is lightly diluted and applied on the prepared surface. The sodium acetate formed during the chemical reaction penetrates inside the pores of the concrete and reacts with water to form crystals to block the pores of the concrete, there by reducing water permeability. 3. Porosity and voids reduction (base Coat application) Applying wetting agent consisting of acrylic monomer, co-polymer liquid and crystallization liquid as base on the prepared surface and V groove and cracks etc. 4. application of sealant / Patching mortar Cracks will be sealed using suitable sealant or patching mortar. These make them ideally suited for joint treatment. Its adhesion is very strong & binds with the building materials such as concrete, and take care of expansion and contraction in the structures. 5. levelling course using Flexible Cementatious material A concrete mix in the ratio 1:1.5:3 (1:cement : 1.5 quartz powder : 3 graded stone) is laid to make haunch at junction of parapet and roof slab and at damaged portions to drain off water. The factory made dry CEMENTATIOUS silica sand power consisting of dry cement mortar (1 cement : 4 silica sand) shall be mixed with additives like ISOPROOF chemical and acrylic polymer and water to arrive at workable consistency. The same shall be applied over the prepared surface to give even surface and act as base for geo- textile fabric. 6. non woven Geo textile Fabric application Two layers of Non-Woven Geo Fabric 40gsm (40=40=80gsm) shall be applied on FCM coating. Geo fabric shall be saturated with acrylic co polymer applied in wet condition. Over this layer, flexible monolithic membrane shall be laid by mixing single component ISO PROOF with water in the ratio of 1:1. 7. Primer Coat A mixture of acrylic monomer (1:1) ISOPROOF & water mixed in proper proportion will be applied on the geotextile membrane. 8. Final Coat Application of a coat of ISOPROOF shall be applied at right angles to the primer coat and drying time is about 3 hours. The rate of completion of ISOPROOF for primer and final coat shall not be less than 1.25Kg per Sq meter (Item No. - 38.3, Page No. 275 )
