WA-EDPM puddle flanges are cast in new walls mounted to the pipe. Waterstops for pipe placed in concrete.






Cast in the floor slab around a pipe, puddle flanges prevent radon gas penetration.

Wall Sleeves non-metallic:


Engineered system for watertight pipe penetrations.

WA.ZVR wall sleeves permanently bonds to the concrete and becomes an integrated part of the wall structure.

The wall sleeve exterior has a special fused incrementation coating that bonds with the concrete for a no leak around the sleeve. The annular space between the pipe and wall sleeve is made watertight by using a WA pipe seal.

A perfectly symmetrical entry point is formed for pipes and conduit passing through the structure.

Westatlantic Tech Corp.

The coating bonds perfectly homogeneously with the concrete.

WA.ZVR sleeves may be set in , block walls, concrete walls or cast in a wall opening using mortar.

Use in conjunction with modular seals, disc seals and press seals, watertight penetration for pipes, conduit or cables .

Pipe Seal system advantages:link-seal-drawing

  • Provides a 36 psi seal, 80 foot. head.
  • Better seal integrity when higher head pressure is present.
  • Corrosion resistance stainless steel hardware.
  • Pipe seals for large or small annular spaces.
  • Pipe seal sizing for all pipe diameters.








Pipe Disc Seals for pipe through concrete walls.

WA-Disc seal systems.

disk-pipe-seals-westlantic Westatlantic Tech Corp. offers a Compression Disc seal system;

WA-Disc seal sizing is determined by the pipe outside diamentes passing through an opening.

Disk sealing is used  wherever a modular seal cannot be installed due to technical reasons.


Disc seal compression plates expand in the annular space for a complete water tight, gas tight and smoke tight system. Disc pipe seals allow small diameter and fraction diameter pipe and conduit to be made waterproof. The ID of the seal opening will match the OD of small diameter pipes.

WA-DL Link Modular Models: for 72 psi - 5 bar tight - 160 foot water head sealing.

link-seal-double-hight-pressure-modular-sealWA-DL high pressure modular link seal elements are available for conditions where pressing water is greater than 36 psi.
