The most common material for interior walls and ceilings in the US is drywall. Drywall is composed of a gypsum center that is surrounded by two paper-based sheets on both sides of it. Due to the materials that makeup drywall it is weaker when wet and can be damaged easily; wet drywall is also susceptible to mold growth and should be dried quickly to prevent this. Drying wet drywall allows it to recover its strength if it’s not wet for too long. Immediately contacting AAA Flood Drying is a great idea if you wish to try to save these after a flood or other type of water damage.
Wet drywall can be saved but you should consider if you’re better off removing it or drying it. If your ceiling is made of drywall and it is wet you should always remove it. Wet drywall ceilings will trap moisture which will damage other structures in the ceiling and will not recover efficiently anyway so you will have to replace it later on. It also poses a safety risk since it can collapse at any time as its supporting layers will be damaged.
Multi-layered drywall is problematic if wet. It is typically found in important structures such as elevator shafts and fire-rated walls, so you must act quickly after it sustains water damage. Since it is found in important structures, removal of multi-layered drywall can may require a consultation with a fire marshall or engineer. Despite this, you can try to save multi-layered drywall by using a wall cavity drying system if you respond quickly enough and the damage isn’t too bad.
