MATERIAL
Waterproofing system
Provide a waterproofing solution that creates a vapour permeable sub-surface barrier to prevent water leakage and ingress of contaminants into the cracks and concrete matrix.
Provide a solution that penetrates into concrete and reacts with Calcium Hydroxide and water at ambient temperatures to form a non water soluble complex calcium silicate hydrate gel in the cracks pores and capillaries.
Material
Provide a solution that is a non-toxic, clear, odourless silicate based material with proprietary biochemical modification.
Cracks
The product must seal existing leaking cracks up to 2.00mm in structural concrete. In the matrix, it shall remain reactive with water to provide autogenous healing properties to future hairline cracks to 0.3mm.
