The crack appears in around 6 hours after filling of STONE-TECH^® mixture. It varies depending on material of cracking object, holes design and temperature, etc. STONE-TECH^® continues to increase pressure for 3 days.
The chemical reaction of STONE-TECH^® and water generates heat. If the reaction goes too quickly, the temperature can be above the boiling point of water before all the water has chemically combined with STONE-TECH^®. This can result in a steam-driven explosion which blows the STONE-TECH^® mortar from the holes with sudden force.
