Coring through cured concrete is slow, messy and expensive. A wall sleeve — also called a pipe sleeve or puddle flange — set before the pour gives you a true, ready-made opening and a dependable surface to seal against later.
Keeps water out
An optional 2″ × ¼″ steel water-stop, welded around the sleeve, locks into the concrete and blocks the path moisture would follow along the outside of the pipe.
Built for below grade
Carbon steel for strength and value, or stainless steel where corrosion resistance matters most — both made to stand up to wet, buried conditions.
Clean, true openings
The sleeve anchors itself in the wall, so the opening stays round, square to the face and exactly where the plans put it.
What you get
Simple part. Serious protection.
Carbon or stainless steel
A36 carbon steel, or Type 304 / 316 stainless steel.
Optional water-stop
A 2″ × ¼″ steel ring welded around the sleeve — centered or wherever you need it.
2″ to 60″ sizes
Sch. 40 pipe through 14″; rolled ¼″ plate for 16″ and larger.
Custom length
Built to your wall or slab thickness, with the water-stop placed where you need it.
Custom diameters
Need a size that isn't on the chart? We'll build to your dimensions.
Bare, primed or galvanized
Choose bare steel, epoxy primed or galvanized. Stainless ships bare.
Walls, floors & foundations
Works anywhere pipe crosses a concrete barrier.
Set by our crew
We can place sleeves as part of our concrete work — one team, no handoff.

Where they go
Set it in the forms. Pour once.
Sleeves are positioned and secured inside the formwork before concrete is placed, then cast permanently into the wall or slab. Because we handle fabrication and concrete in-house, we can supply, place and pour around your sleeves on the same job.
Foundation walls for water, sewer and utility service lines
Floor slabs where piping drops to the level below
Vaults, pits & tanks that need to stay dry inside
Industrial & oilfield process piping through concrete
