Application Instructions
- In the case of large spaces between pipe and inner walls, back fillings may be required. Use back paddings to create the application depth of minimum 12 cm.
- Soudapack WST should be used on the inside of cable/pipe penetrations for flexible sealing.
- For watertight and gastight seals around (and on the outside of) cable and pipe penetrations, Soudal Aquaswell is recommended.
- A top layer of a water-resistant mortar (Soudaplug ST) to encapsulate Soudapack WST is recommend.
