Quick Answer
Build a fire pit with a raised platform using gravel or rocks to allow air to circulate and water to drain, and surround it with a fire ring or a metal shield to contain sparks and embers.
Designing the Fire Pit for Drainage
When building a fire pit in a wet area, drainage is crucial to prevent water from accumulating and extinguishing the fire. To achieve this, create a raised platform using gravel or rocks with a slope of at least 1:6 to allow water to flow away from the fire. The platform should be at least 12 inches high to prevent water from seeping into the pit.
Fire Ring or Metal Shield
Surround the fire pit with a fire ring or a metal shield to contain sparks and embers that may land on the surrounding vegetation. A fire ring can be made from rocks or metal, while a metal shield can be a sheet of metal with a hole in the center. The shield should be at least 2 feet wide and 1 foot deep to contain the fire.
Choosing the Right Materials
When building a fire pit in a wet area, choose materials that are resistant to rust and corrosion. Metal fire rings or shields can be made from stainless steel or aluminum, while the raised platform can be made from gravel or rocks. Avoid using flammable materials such as wood or plastic, as they can ignite easily and spread the fire.
