No grouting - expander clamp attachment inside the core opening - compression clamp seals to the pipe.

Expander clamp WA- ZW- pipe to tank seals, are a one piece no joint fit. Pipe sizes 3 inch to 12 Inch (80 mm-300mm). Allows pipe flex for laterial movement or axial movement of the pipe.

septic-tank-pipe-entry-seals Sanitary sewer applications for pipe to septic tank and manhole chamber connections.

WA-ZW tank seals allows angular movement of pipeline up to 12 degrees in all directions plus linear movements up to 50 mm. (2")

The entry boots are easy-to-install. Materials are EDPM boots and 304 L stainless steel expander clamp bands.

The expanding seal ring protects against migration of underground water into the structure and prevents fluids escape from the containment system.










Expansion manhole EDPM connectors, protect against inflow and outflow from the chamber.

WA-ZW seals allow:

Angular displacement of the pipe up to 12º in all directions.

Linear displacement up to 50 mm.

  • Sealing units fit pipe DN80 - DN300. (3 inch to 12 inch)
  • Temperature max. -30°C to +110°C.
  • Gas and water tight, pressure max. 0.5 bar (7.25 psi or 17 ft. water head.
  • Expanding clamps for the chamber core and fastener bands for the pipe are 304L stainless steel.

Westatlantic Tech Corp., WA.DWRS Internal pipe seals - leaking joint repair.










Pipe and manhole joints experience high ground water pressure and is usually the source of leaks. Internal joint seals provide a watertight flexible seal and is a permanent fix for leaking joints.

Internal WA.DWRS pipe seals are designed to stop leaks caused by pipe settlement or misalignment. The seals may be used on concrete, HDPE and most other type of pipes. Access to the inside of the pipe is required in order to place the seal.

Iternal expanding seal installs easily with a simple expanding tool which is provided with the seal.

Wider internal joint seals are available to provide an elongated coverage area. The internal joint seals fit most American and International pipe and manhole diameters.

Available in EDPM and NBR elastomers with stainless steel expander clamps.

Flow Stopper mechanical pipe seals - Link modular seal Plugs

Mechanical Disk expander Plugs

pipe-flow-stoppers-link-modular- rim-seals

Pipe Plugs, Link Modular Seals or Disk expansion Rim Seals. By-pass or non-by-pass drains. Mechanical seals for quick installation and dismantling.

All pipe sizes. Stainless steel or Galvanized Steel material. EDPM, NBR elements.

For larger pipes or higher water head, bolt anchors or bar bracing forms part of the assembly. This type of plug may be used on multiple projects and the seals may replaced for long life usage.


PSI Sealing Plugs - Bulkhead Seals - Marine



PSI Plug Seals Split designed seal cables and pipes passing through walls, ceiling and bulkheads. PSI compression plugs provide a tight water and gas seal.

Installation is fast and simple, the plug is pressured in the annular space. The profiled design of the seal makes installation easy and ensures a 3 bar (40 psi) tightness.

All PSI plugs are manufactured from high quality rubber and are highly resistant to abrasion. PSI plugs are supplied with five different rubber types to ensure suitability for all industry sectors, such as construction, marine, power and offshore.


pipe-plug-throught-wall-waterstopPSI - compression Sealing Plugs are applicable to the ship building industry, and are installed from both sides in a welded sleeve through a wall or deck.

In ship building the high fire retardant rubber FS. Fire resistance of 60 minutes are used. The welded in sleeve will then be wrapped with Rockwool.

Other fire resistant assemblies may also be added to provide more fire wall protection.

Sealing a wall opening; the plug can be used in a core drilled hole. The plug is pressured into the annular space around the pipe penetration.

The plug can also be used in embedded pipe inlet wall sleeve assembles.

  • 60 minutes fire retardant (A60)
  • Resistant to gas, water and pressure
  • Large range of sizes available
  • No specific tools necessary for installation
