Sika-4A Waterstop FAQs
What is Sika-4A Waterstop?
Sika-4A Waterstop is rapid setting water stopping cement additive for ordinary Portland cement.
How do I mix Sika-4A Waterstop?
- Before starting to work with the material wear suitable protective clothes, gloves and googles.
- Mix Sika-4a with clean water at the desired dilution rate, depending on the application and water pressure.
- Pour the liquid into a clean mixing container.
- Quickly pour the cement in until the liquid is covered (approximately 3 parts of cement to 1 part liquid).
- Mix the materials quickly and thoroughly into a paste and use immediately. Do not mix more product that can be placed immediately.
How do I prepare the surface for using Sika-4A Waterstop?
Surfaces to be treated with Sika-4a shall be thoroughly cleaned, roughened, and washed with fresh, clean water to remove any dirt, debris, loose, particles or contaminants. Level off any sharp surface protrusions. Cracks may need to be enlarged to increase the bond.
How do I apply Sika-4A Waterstop?
- Mould the Sika-4a paste by gloved hand into a plug and place it immediately into the hole, pressing firmly until the mix has set.
- Once sealed Sika-4a must be overcoated with a coating of Sika waterproofing mortar.
- In areas of medium to heavy water infiltration, divert the water to discharge points formed of short lengths of plastic tube bonded into drilled holes using Sika-4a. This will reduce the pressure until the waterproofing final render has fully hardened. The plastic tubes can then be removed and the holes plugged using a mix of Sika®-4a (diluted 1:1 with water) with cement. Do not apply final layer of the render until discharge tubes have been removed and water infiltration has stopped.
- Where high water pressures are experienced, the prepared area around the discharge tubes may need to increase to provide a larger surface area for bonding the Sika-4a paste.
