Waterproofing

 

3:1 Tanking Mix

Larsen 3:1 Tanking Mix is a premixed waterproofing render which provides a highly effective damp-proof render used to waterproof new or existing brick structures. It consists of portland cement, specially selected aggregates and our crystal growth waterproofing additives.

 

The special crystal growth waterproofing additives combine with free lime and moisture to form insoluble crystalline material which blocks the capillaries and hairline cracks to prevent water ingress while still allowing the passage of water vapour to allow the structure to breathe. 3:1 Tanking Mix is suitable for use on new or existing brick structures and contains no harmful or corrosive substances that will attack steel reinforcing - chloride free.
