Frequently Asked Questions (FAQ)

What are the advantages of using two or three components for the Krystol Waterstop System?

Using more than one waterstop material provides redundancy and can keep joints dry even if there is a problem with the installation of any one component. As there is no “perfect” waterstop, using materials with different properties allows the strengths of each component to compensate for the limitations of the others, providing the greatest reliability.

Krystol Waterstop Grout provides a strong, physical barrier to water penetration and also contains Krystol chemicals to provide long term waterproofing.

Krystol Waterstop Treatment is rich in Krystol Chemicals and provides waterproofing along the full width of the joint. Applied as a brush on treatment, Krystol Waterstop Treatment easily adapts to rough, uneven surfaces and provide edge-to edge protection. Unlike most waterstop products, Krystol Waterstop Treatment provides protection for the outer layer for reinforcement. Kryton provides physical better with quick swelling and sealing action, and will typically seal small leaks faster than the other waterstop components.


What are the advantages to waiting 28 days before installing Krystol Waterstop Grout?

Waiting 28 days allows for initial concrete shrinkage to take place first so that the joint is more stable for installation of the Grout. The waiting period also provides leaking joints time to self-seal.

Installing Krystol Waterstop Grout after less than 28 days increases the changes of the joint leaking due to shrinkage or movement of the concrete, which may lead to call-backs for additional repairs.
