Removing a deck base primarily involves dismantling the structural support components, such as beams, posts, and footings, which typically occurs after the deck's surface and railings have been removed. This process is part of a complete deck demolition.
The "deck base" refers to the foundation and support structure that holds the deck surface aloft. Based on a standard deck removal process, taking down this base follows the removal of the upper deck layers and elements.
Steps for Removing the Deck's Support Structure (The "Base")
According to standard procedures for deck demolition, the removal of the structural base elements happens in the later stages. Here are the key steps specifically related to dismantling the support structure:
Step 6: Remove the Deck Beams
- Identify the beams: These are the primary horizontal supports that carry the joists and transfer the load to the posts.
- Detachment: Beams are often attached to the ledger board (if present) and rest on or are attached to the tops of the posts. Carefully detach them from these connections. This might involve cutting bolts, screws, or nails.
- Lowering: Once detached, safely lower the beams to the ground. Beams can be heavy, so plan the removal carefully and use assistance if needed.
Step 7: (Optional) Dig Up the Deck Posts & Footings
- Expose the posts: Posts are vertical supports that hold up the beams. They are usually set in concrete footings below ground level.
- Cutting or Detaching: Posts are often attached to the beams and footings using hardware. You can often cut the posts off at ground level or, if the goal is complete removal, detach them from the beams.
- Footing Removal: To remove the entire base, including the footings, you will need to dig around the concrete footings.
- Digging: Excavate the soil around the footing to expose it fully.
- Breaking or Lifting: Once exposed, the footing can be broken into manageable pieces using a sledgehammer or jackhammer, or potentially lifted out if it's not too large and deeply set.
- Complete Removal: Ensure all parts of the post and footing are removed if a clean demolition site is required.
Context: What Happens Before Removing the Base?
It's important to note that removing the deck base is not the first step in a deck demolition. Standard procedure involves dismantling the deck from the top down. The steps preceding the removal of the beams, posts, and footings typically include:
- Accessing the deck and identifying hazards.
- Removing the deck railing.
- Removing deck boards (the surface).
- Cutting and removing the joists (the framing members that support the deck boards).
- Demolishing the deck stairs.
- Removing the ledger board (if the deck is attached to the house).
By following these steps in sequence, you systematically dismantle the deck, culminating in the removal of the base structure. Always prioritize safety and use appropriate tools and protective gear throughout the process.
