Hydroprufe LG


Designed for both horizontal and vertical application on substructures and basements. It is suitable for application onto both new structures and existing concrete or masonry to provide a seamless membrane. It can also be applied where there is complex gas and damp proofing details.


Elastomeric, single-part polymer modified liquid that dries to form a flexible, black membrane. This high performance product is suitable for gas proofing, damp proofing and waterproofing of vulnerable concrete structures.

Features and benefits:

  • Due to rapid drying properties installation is quick.
  • Low permeability to methane, carbon dioxide and radon gases.
  • Can be used as a vertical and horizontal damp proof membrane.
  • Will provide a seamless coating, therefore eliminating any weaknesses within the membrane.
  • Non-toxic water based liquid.
  • May be painted or screeded over.
