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.
