Which of the following statements is NOT true with respect to chemical grouting?

Explanation:

• Chemical grouting often requires a high level of skill to ensure proper mixing, injection, and reaction of chemicals. Incorrect application can lead to ineffective sealing, over-application, or damage to the surrounding material. Therefore, skilled technicians are typically required.

 Additional Information

Can be employed to treat very fine fractures in moist environments.

• Chemical grouting is effective for sealing fine fractures in structures, even in moist or wet environments, making it versatile for various underground or deteriorating concrete applications.

Can be used to treat narrow concrete cracks.

• It is commonly used to seal narrow cracks in concrete. The chemical grouts can penetrate tight spaces and solidify, providing a strong, durable seal that prevents further damage or leakage.

The chemicals react with water to form gel/solid precipitate.

• The process typically involves chemical reactions with water, resulting in the formation of a gel or solid precipitate. This reaction helps fill cracks and voids, sealing them effectively while also adding structural integrity.
