Pipe Sleeves with Puddle Flanges

Cast In Sleeves for Concrete walls and Floor slabs

Westatlantic pipe entry and pipe sealing Systems.

ontario-wall-sleeve-suppliersPipe sleeves provide openings for pipe passage through concrete walls and floors. Wall sleeves are available in stainless steel, galvanized steel or non-metallic materials.

Cast in Wall Sleeves are designed for all pipe sizes. "Modular Mechanical Elastomeric Seals" seal the annular space between the pipe and the sleeve.

Modular seals are supplied with the wall sleeves and form part of the assembly.

Westatlantic Stainless steel wall sleeves offer maximum corrosion resistance. Integrated puddle flanges, provide waterstop and anchor point features for the sleeve.

Wall sleeve diameters allow annular space best suited for the modular seal. Depending on length of the pipe sleeve, a second puddle flange may be attached to the assembly.

Floor Slab stainless steel pipe sleeve

pipe-sleeve-floor-slabFloor slab pipe sleeves for pipes through floors and concrete slabs.

Used in slaps 6 inch or more. Two stainless steel band straps secure the EDPM Puddle Flange to the sleeve. The Puddle Flange prevents water creep along the sleeve.

All sleeve sizes are available to allow pipe passage for both large and small pipe diameters.

Sleeves may also be PVC models with Puddle Flange waterstops.

Split Wall Sleeves - Split Pipe Sleeves

For all American and International pipe sizes

WA. Split pipe sleeves are used when new concrete walls or slabs are placed across existing pipes. Split pipe sleeves models are bolt closed or a weld closed. Standard split sleeve lengths are 12 inch long and sized to accommodate the diameter of the existing pipe. Longer sleeves are available.

Bolt close models come with a flange design, plus bolt closing hardware. Weld closing models come with beveled axial splits for welding. Split disk compression seals or modular seal links are supplied if sealing is required.

When longer sleeve lengths are required, former ribs are placed along the sleeve length as required for anchoring and to insure ovality of the sleeve.

Model KS pipe sleeve assemblies are used for large diameter pipes - up to 120 inch., and up to16 ft.. long.

KS pipe sleeves have thicker walls and are fitted with waters top Puddle Flanges.

Puddle flange former ribs insure stability, provide anchor points, and ovality. KS wall sleeve assemblies come with Modular Mechanical Elastomeric Seals , that seal the annular space between the pipe and sleeve. EDPM, NBR, Silicone elastomers may be selected for the modular mechanical seals.

KS Pipe sleeves are cast in for new poured walls or used for grouting in applications when breakout openings are required for new pipe entries.

Split wall sleeves, KS models, for existing pipes come with weld up seams or bolted closings.

Engineered wall sleeves prevent deformations that may occur during concrete pouring. They are available for all pipe sizes.

Two basic measure requirements for pipe sleeve sizing are:

Outside diameter of the pipe going through the wall sleeve.
Thickness of the concrete wall determines the length of the sleeve.

Flange to Flange Pipe Sleeves with Puddle flanges.

wall-sleeve-flange-ends-ffWall sleeves normally come with Modular Mechanical Elastomeric Seals to fill the annular space between pipe and sleeve wall.

Disk grommet seals with stainless steel compression plates may also be use as the annular space seal in conditions where pipe is not centered or several pipes through the same sleeve is required.

Stainless steel Wall Sleeves with Puddle Flanges, in multiple configurations are available.





WA-GP Disk seals are used if more that one pipe or conduit passes through the same sleeve, or when the pipe is not centered through the Wall sleeve.







MULTIPLE Wall sleeves with Puddle flanges, may form part of a new pour concrete wall:

Stainless Steel Wall Sleeves for Pipe Cluster penetrations, may be required for certain applications.

Cluster wall sleeves provide for two or more pipe entry points through a concrete wall.

The sleeves may be attached or provide minimum space between pipes to allow for concrete placement.

Pipe penetrations through multi wall sleeves are individually sealed with a compression elastomer seal of a link modular belt type seal or disk plate type seal.


Pipe Sleeves for Foundation Liners.

Pipe and Liner combination wall sleeve seals.









MULTIPLE or single openings seal both the liner and the pipe.

Liner and pipe sleeve seals, provide water proof membrane seals and a pipe seals in one monolithic wall sleeve assembly.

The assemble comes with Modular Mechanical Elastomeric Seals for the pipe and a clamp seal for the foundation liner.

Puddle Flange pipe sleeves with end sleeve wall collars for thick concrete walls.


Long length pipe sleeve assemblies with wall collars come complete with disk pressure plate seals for each end of the wall sleeve.

Sleeves are available for pipe sizes 25 mm - 2000 mm diameters.

EDPM, NBR or Silicone electrometers elements are available.


Split long length pipe sleeves are also available..

ZVR pipe sleeves are tough pipe sleeves utilizing an inherently stable plastic structure. A special cementation coating for cement-bounding forms part of the sleeve structure. They maintain complete ovality during the pour.

The cement bonded pipe sleeve can be set in concrete. Block wall pipe penetrations use ZVR model pipe sleeves for cast in wall openings, when a mortar refit is required.

Fiber Cement Wall Sleeve for Concrete wall or block wall construction.


Asbestos-free, corrosion-resistant fiber-cement wall sleeve are installed for pipes through walls, ceilings or floors.


Fiber cement wall sleeves are also used for new walls, or mortared in wall sleeves. Split, or two half wall sleeve sections are used when pipes already exist.

With an outside groved surface, concrete grout fusing occurs, forming a completely no leak around sleeve.

Fiber cement wall sleeves do not require a smooth core hole and may be place and grouted into a square or hammered out wall passage. Pipe passing through the sleeve are sealed water tight with a modular seal.

The opening may house a single pipe or several pipe penetrations and sealed with a single LPS Link seal or multi pipe Disk seal.

Angled pipe wall sleeves for incline pipe through a wall for slab.


WA-PD-KP" pipe sleeves for walls or floor slabs are use when pipes pass through a concrete structure on an angle. Tapered ends and angled puddle flange waters stops, are matched cut to the pipe entry angle.

Angled wall sleeves allow pipes to pass through concrete walls on a straight axial line, eliminating additional bends. Incline pipe sleeves come has a split model if pipes already exist.

A GP seal for angled pipe sleeves, creates a 36psi watertight passage - up to 80ft. head of pressure.

For installation, extended bolting make accommodations for the degree of incline.

Split wall sleeves for existing pipe, are available with either weld closings or bolted closing models. They are available for most pipe sizes and accommodate existing piping, when new walls or slabs are placed.

Sealing elements may be EDPM, NBR for hydrocarbon applications or silicone for heated pipes.



Bolted tank wall Sleeve Assemble - GPC Model Stainless steel

GPC sleeves are bolted to a steel tank wall or other steel structure and sealed with a back plate flange gasket. The pipe or conduit passing through the sleeve, is sealed with a Disk-Seal.

The Disk grommet seal is a split model, for easy mounting around the pipe. Disk-Seals may be configured for more than one pipe.

The back plate may ordered in a curved configuration to accommodate a round tank wall.

External Wall Mount / Slab mount / Thimble pipe sleeve seals

Bolts to the wall or slab and sealed.



WA GP.T pipe sleeves and seal assembly is designed for external pressure sealing pipes and cables. They may be installed for pipes through manholes, slabs, concrete walls, building foundations or floors.







The assembly is comprised of a sleeve and back plate for fastening to the wall. The back plate is sealed at the wall. A link type annular seal, or disk seal, seals the pipe watertight.

Disk seals are used when more than one pipe is passed though the sleeve. The back plate may be round or square.


A thimble wall sleeve may be split for existing pipes and may be angled to accommodate incline conditions. see samples below.

For Several pipes through the same wall sleeve, GP.T disk seals may Conduit-seal-cable-pipe-through-metaldisk-grommet-seals-pipe-through-wall-sleeveaccommodate several pipe through the same sleeve opening.. Use Split Disk-seal grommet seals, for conditions where the pipe or conduit is already in place.
