Application

Remove all loose material and mechanically roughen, clean and enlarge bond area around the leak. If necessary, divert leakage to discharge points formed of short lengths of plastic tube bonded into drilled holes using Sika®-4a Waterstop paste and gradually seal off water working towards the discharge points. Use neat or dilute Sika®-4a with clean water to meet the severity or pressure of the leak. Maximum dilution 1:4 – Sika®-4a:water. Only mix sufficient for immediate use. To seal the leak, mould paste by gloved hand into a tapered plug and immediately force into the prepared hole and hold until set. Setting time is affected by ambient, water and Sika®-4a Waterstop temperatures and supply/age of cement. Trials recommended. Sika®-4a Waterstop repairs must be over coated with a proprietary Sika® Waterproofing System. For full details, limitations etc. refer to data sheet, product label or contact Sika Limited
