N-13

• Building Chemist N - 13 system is a surface-applied crystalline waterproofing treatment for concrete structures that is used to protect against the ingress of water. It is a dry powder, that when mixed with water becomes a coating that is applied to the inner or outer surface of the concrete structure.
• Building Chemist N - 13 is used in conjunction with Building Chemist N - 11 as a second coat or for coating on existing concrete surfaces for negative side waterproofing.
• Building Chemist N - 13 contains Building Chemist’s unique and proven Building Chemist technology which reacts with un-hydrated cement particles to form millions of needle-like crystals. These crystals grow in a catalytic reaction, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants. Later, if cracks form due to settling or shrinkage, incoming water triggers the crystallization process and additional crystals form, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected. The concrete itself becomes the waterproof layer removing the need for any surface treatment.
• Reliable Waterproofing: Eliminates the need for exterior membranes, penetrates deep into concrete, and remains unaffected by surface wear.
• Self-Sealing Cracks: Automatically seals hairline cracks (up to 0.5 mm) and reactivates in the presence of moisture, ensuring long-lasting protection.
• Versatile Application: Suitable for old and new concrete, safe for potable water, and works on both positive and negative sides with Building Chemist N-13.
• Certified Durability: CE-certified (R3 Category) with superior corrosion protection, reducing maintenance costs and enhancing performance.
