Load test Certificate mandatory. The complete process must be as per manufacturer specification and satisfaction of Engineer-in-charge. Single Wrap. Quoted rate shall be including GST as per present rates , lead , lift , testing, transportation , sampling etc. complete. Nothing extra shall be paid separately. Approved Makes : Sika / Fosroc

Structural Strengthening by Supply and apply Carbon fiber Wrap FRP fabric SIKA 230C including cleaning & repair the surface and remove losse concrete, chipping of corner, ply etc. This can be achieved either by grinding, or by building up with Sikadur® mortars. Internal corners must be made smooth by trowel application of Sikadur® epoxy mortar into the prepared corners. Apply Sikadur®-330 to the prepared substrate using a trowel, roller or rush. Place the pre-cut dry SikaWrap® fabric in the required direction onto the Sikadur®- 330 priming layer. Second layers of SikaWrap® fabric are installed by applying the Sikadur®-330 onto the previously applied layer ‘wet on wet’ and within 60 minutes (at +23 °C) of the previous layer, and repeating the laminating procedure outlined above for the first layer of fabric. The complete process must be as per manufacturer specification and satisfaction of Engineer-in-charge. Single Wrap. Quoted rate shall be including GST as per present rates , lead , lift , testing, transportation , sampling etc. complete. Nothing extra shall be paid separately. Approved Makes : Sika / Fosroc
