PENETRON or Sika: how to select a waterproofing system

By Igor Semeonidis

# PENETRON or Sika: selecting a system The correct choice is based on the water source, substrate, pressure, movement and access—not on brand name alone. Crystalline systems suit certain concrete conditions; cementitious coatings suit suitable mineral surfaces; PU injections address selected water paths; epoxy suits selected stable cracks; chemical DPC addresses confirmed rising damp. A material name without a diagnosis, detail drawings, preparation plan and quality control is not a waterproofing system.
