Armaflex in Concrete

To prevent Armaflex from being crushed by wet concrete, you can: 

• Pour concrete so that it's only about 25 mm thick over the Armaflex, then pour more concrete to reach the desired thickness 
   
• Protect the Armaflex with a rigid outer pipe or covering 
   

Before applying Armaflex, ensure the concrete is clean, dry, and free of contamination like oils, mould, or flakes. Porous concrete may need to be sealed with a liquid sealant to prevent the adhesive from being absorbed. 

Adhere the Armaflex to the concrete using Armaflex adhesive. Follow the recommendations in the Armstrong Armaflex Installation Manual. 

When sealing glued joints, push them together instead of pulling them. 

Wait 36 hours before using the Armaflex or until the adhesive is fully cured. 

Armaflex is an elastomeric foam product that may wrinkle slightly due to temperature differences. This is normal and doesn't affect the product's performance.
