Penetrations automatically occur wherever components need to be carried through a waterproof barrier/membrane (or concrete in the case of the "White Tank" system). Such components include:

• Shafts or manholes
• Pipes
• Steel sections or parts
• Tie bolts
• Gullies/floor drains
• Filter wells

A range of waterproofing options, each working in a different way, is available to cater for the varying diameter, geometry and material of the penetrating element:

Grouting systems

• RASCOtec injection channel: cementitious bases, penetration upwards of 60 cm diameter
• RASCOtec injection collar: all materials, penetration up to 60 cm diameter
• RASCOtec multiple-penetration unit: all materials, pipe bundles

Hydrophilic systems

• RASCOtight hydrophilic strip: all bases, all geometries, dry conditions when installed
• RASCOtight hydrophilic paste: all bases, all geometries, dry conditions when installed
• RASCOtight hydrophilic tie bolt plug: formwork tie bolts

Bonded systems

• RASCOjoint TPE waterbar: steel, dry, cementitious bases, tie bolt locations in general

Given the countless different shapes and sizes of penetration, along with their wide-ranging functions and constituent materials, choice of the most suitable waterproofing product is always governed by the particular circumstances.
