Gel-Seal is a chemically modified silicate solution that provides long-term waterproofing and durability benefits to concrete. It penetrates deep into concrete and reacts with free calcium and water to form a water-soluble calcium silicate gel complex in cracks, pores and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.
Gel-Seal remains reactive upon contact with water to provide continuous healing properties to future hairline cracks. Therefore, a single application can deliver many years of protecting against freeze-thaw degradation and salt ingress. It protects the concrete and reinforcing steel. It offers major cost savings for both new infrastructure work and renovation activities. Gel-Seal is suitable for all types of Portland cement concrete mix designs.
