What are Anchors for Wet Concrete?
Anchors for wet concrete are cast in place fasteners set before the pour. After the slab cures, they leave durable internal threads so you can attach threaded rod or bolts without drilling. Popular styles include Blue Banger Hangers and roof deck inserts.
Why use Blue Banger Hangers in fresh concrete
- Place before the pour to save time with no post install drilling
- Clean finish with ready to use threads once concrete reaches strength
- Reliable anchorage formed inside the slab for overhead supports
- Less dust and vibration compared to drilling cured concrete
Where Anchors for Wet Concrete are used
- Ceilings for cable tray and lighting
- MEP supports for pipe, conduit, and duct
- Fire sprinkler mains and branch lines
- Metal roof deck with matching inserts and span brackets
Types of Blue Banger Hangers and inserts
- Cast in place hangers for formed slabs
- Pour in place hangers set quickly during placement
- Roof deck inserts and span brackets for steel deck profiles
- Placement tools to speed layout and ensure alignment
Sizing and fit for wet concrete anchors
- Match the internal thread to the rod or bolt size you plan to hang
- Verify embedment depth, spacing, and edge distance on the product sheet
- Choose models compatible with your formwork or deck profile
- Plan rod length and clearance for finishes and equipment
Materials and finishes
Zinc plated steel
General purpose corrosion protection for interior projects.
Stainless steel options
Improved corrosion resistance for damp or outdoor exposure when available.
Installation tips for Blue Banger Hangers
- Attach securely to formwork or steel deck so the insert stays perpendicular
- Mark locations clearly to avoid clashes with rebar and sleeves
- After curing, clean the threads and install the specified rod or bolt
- Load only after the concrete reaches the required strength
Blue Banger Hangers vs drilled anchors
Cast in place hangers reduce labor and keep surfaces clean by eliminating drilling. Use wedge or sleeve anchors when working on existing cured slabs or for retrofit locations you could not set before the pour.
FAQs about Anchors for Wet Concrete
Clear answers on selection, sizing, placement, and use after the pour.
- What are anchors for wet concrete?
They are cast in place inserts installed before pouring that create internal threads in the cured slab for threaded rod or bolts.
- Why choose Blue Banger Hangers instead of drilling later?
They save labor, avoid dust and vibration, and provide ready to use threads as soon as the concrete reaches design strength.
- Where are these anchors typically used?
Overhead MEP supports, sprinkler systems, cable tray, lighting, and roof deck attachments.
- How do I pick the right size?
Match the internal thread to your rod or bolt size and confirm embedment, spacing, and load rating for the hanger model.
- Can I use them on metal roof deck?
Yes, choose deck specific inserts or span brackets listed for your deck profile.
- Do I need special tools to set them?
Placement tools help hold alignment and speed layout, especially for large runs, but basic installs can be secured to formwork without specialty tools.
- When can I load the hanger?
Only after the concrete cures to the specified strength per the product guidance or engineer of record.
- What if a location was missed during the pour?
Use a post installed solution such as a wedge or sleeve anchor sized for the load and base conditions.
