When MDMA crumbles, it typically means that the substance has degraded or lost its structural integrity. This can happen due to exposure to heat, moisture, or other environmental factors. Crumbling MDMA may indicate that it has lost potency or purity, making it less effective or potentially dangerous to consume. It is important to properly store MDMA in a cool, dry place to prevent it from crumbling and maintain its quality. **

If the mortar in a self-built wall is crumbling, it may be due to several factors. One possible reason is that the mortar mix was not properly proportioned, leading to a weak bond between the bricks or stones. Another reason could be that the mortar was not mixed thoroughly, resulting in a poor consistency. Additionally, if the wall was not properly cured or protected from the elements during the setting process, the mortar may not have achieved its full strength. It's important to assess these potential issues and make any necessary adjustments to ensure the stability and durability of the wall. **

Grout can crumble and floor tiles can come loose shortly after installation due to improper installation techniques.

Additionally, if the subfloor is not level or stable, it can cause the tiles to shift and the grout to crack. It is important to follow manufacturer guidelines and ensure proper preparation and installation procedures to prevent these issues. **
