Century Line Sleeves Application & Installation

Century-Line® Model CS Sleeves in Combination with “low durometer” EPDM (blue) Link-Seal® Modular Seals

Century-Line® Model CS Sleeves are ideal for poured wall construction. Made of HDPE thermoplastic, they are lightweight and easy to handle. Moulded-in water-stop and reinforcing ribs serve to anchor the sleeve in the wall and resist pour forces. Nailer end caps are provided to make placement in forms simple and accurate. Sleeves are available in various diameters, from 50 mm (2”) up to 628 mm (25”). In the event of a field change they can be shortened with ordinary hand tools.

Century-Line Sleeves in formwork

Hollow water stop collar and nailer end caps simplify installation. The unique water stop collar acts like an expansion joint, adjusting (up to 1/2″ – 12.7mm) to the thickness of the wall. In addition, nailer end caps may be nailed to concrete forms and when removed from the poured concrete they form a smooth beveled finish on the concrete faces.

Century-Line Sleeves in Shotcrete

For shotcrete applications, Century-Line® Sleeves are easily positioned to the wall form with threaded rod, and the end caps protect the sleeve penetration while the wall is formed.

Century-Line Sleeves in Concrete

Specially designed end caps provide an ideal method for attaching Century-Line sleeves to the concrete forms. The end caps ensure that the sleeve holds its circular configuration during the pour. In addition to keeping out wet concrete, they also prevent dirt from entering the sleeve during backfill operations or the interim construction period.

Century-Line Sleeves are lightweight and easily installed by one construction worker. No special tools or equipment are required for the installation.

Step 1: Measure the center line to position Century-Line® Sleeve end cap.

Step 2: Nail one of the end caps at the marked center line.

Step 3: Place the Century-Line® Sleeve on the end cap. When field cutting non-standard CS sleeve lengths, the sleeve and endcaps total length should be 6 mm (1/4”) longer than the thickness of the wall.

Note: To ensure minimum water migration, center the water stop in wall by cutting equal lengths from each end of the sleeve, except as noted below.

Step 4: Place second end cap on sleeve. Check to determine that the cap is properly inserted

Step 5: For additional stability, it may be necessary to secure the sleeve with wire to the rebar. Insert the other end cap firmly, check that second end cap is positioned correctly, confirm sleeve length and close the form.

Step 6: After the concrete is poured and cured, remove end caps with screwdriver or crow bar. End caps may be replaced to protect sleeve until pipe penetration is made
