Azo-Grout™ by Azon
Hydrophobic and hydrophilic polyurethane commercial grout products
The hydrophobic grouts deflect water away from the repair area and require a minimum amount of water for reaction. The hydrophilic materials absorb a certain amount of water to form a flexible foam or gel to protect the repair area from further penetration by acting as a watertight seal or membrane.
