Composeal Blue Vinyl Shower Pan Membrane

Composeal Blue Vinyl Shower Pan Membrane

Flexible Waterproofing for Floors – Walls – Roof Deck / Terraces – Under “thick bed” Tile Installations

PRODUCT PRESENTATION

COMPOSEAL is a blue flexible PVC waterproofing membrane manufactured in 30 and 40 mil thickness in widths of 48″, 60″ and 72″, packaged in 100 ft.and 50 ft. rolls. Unlike ready made units of plastic or metal, COMPOSEAL can be formed to fit any dimensions or drain locations.

USES, APPLICATIONS

COMPOSEAL is used as a concealed waterproofing membrane for showers, Roman tubs, whirlpool bath enclosures, fountains, roof decks and terraces. COMPOSEAL cannot be used as a liner for pools containing fish or water plants.COMPOSEAL is also used extensively in renovation and remodeling, and in the northern climates, as a liner for outdoor hockey rinks.

OVERALL PRODUCT IN PLACE

COMPOSEAL is used generally under tile or marble as a waterproofing membrane beneath a “thick set” mortar bed of 1 ¼”-2″ above a substrate of wood or concrete.

INSTALLATION

Before placing pan, see that the sub-floor is sloped toward drain ¼” per foot using cement mortar if necessary, and is free of loose objects or projections such as nailheads or gravel.

Make turn-up along walls not less than 3″ above curb line, allowing sufficient material to fasten to outside face of curb.

Notch wood studs to ½” to the height of the pan to allow COMPOSEAL to be flush with face of the studs. For metal studs, use furring strips (¼” to ½”) above the top of the pan.

Fasten 3″ or higher above the top of curb. Use flathead roofing nails or staples on wood studs. Use drywall screws and washers on metal studs.

Fold corners outside pan as illustrated. Allow for plumb surface by turning corner folds of pan out of way between studs and notch studs or use furring strips mentioned above to maintain a flush surface. Do not cut pan corners.

Use bold-down clamping-ring type drain with weep-holes. Set so subdrain lip is flush with subfloor.

Trim for drain exactly to size of drain opening. Do not trim out to bolt holes, but pierce to accommodate bolts with a tight fit.

Use butyl caulk or equal between pan and subdrain. Plug subdrain and fill pan with water and let stand for 24 hours to insure clamping ring is tight and pan undamaged. Bolt clamping ring firmly. Place a small amount of gravel or other porous material at weepholes so they remain clear when setting bed is poured. In areas under the jurisdiction of the UPC/IAPMO plumbing code, a 15 lb. felt underlayment is required under 30 mil shower pan liners. (The City of Los Angeles no longer requires this underlayment.) No underlayment is required for use with COMPOSEAL 40 mil thickness.

COMPONENTS, PARTS

COMPOSEAL’s multi-purpose, preformed corner/curb protector is available to reinforce waterproofing at all corners and curbs. These protectors are sold in pairs and can be used for all outside corners as shown in the 3 illustrations to the right. Compotite does not recommend inside corners which, when cut, weaken the installation.

CODES, CERTIFICATION

COMPOSEAL 30 and 40 comply with the three major plumbing codes: UPC-IAPMO, SBCCI and BOCA. COMPOSEAL has separate municipal approval where required, e.g. City of Los Angeles, City of Philadelphia (40 mil), Metropolitan Dade County and Commonwealth of Massachusetts. (Approval is no longer required in New York City for concealed PVC waterproof membrane).

COMPOSEAL also complies with the Corps of Engineers specs for PVC shower pan material (para 5.8.3.2 15 p1-18) and meets the requirements of FHA Publication 4900.1.

WARRANTY: COMPOSEAL 30 and 40 are warranted against failure for any reason, and in the event of failure, replacement material will be supplied at no charge. This warranty applies only to the membrane itself and not to the manner of installation over which we have no control, and it does not extend to consequential damage or other implied responsibility. COMPOSEAL should last the life of the building.

OPERATION, MAINTENANCE

COMPOSEAL requires no maintenance and should last the life of the building.

MATERIALS, FINISHES

CEMENT WELDING: COMPOSEAL may be welded by the use of a flexible vinyl solvent cement which gives instant contact strength. COMPOSEAL SOLVENT CEMENT is available for this purpose. Use only Compotite approved PVC cement for seaming and welding Composeal. Lay sheets with an overlap of two inches with upper lap edge towards direction of watershed. Fold back top edge and apply the cement to both surfaces. Place together after surfaces become tacky, about two minutes, and press or roll with a roller, first lightly so as to avoid slippage, then firmly, but not so hard as to distort the material

Technical Data

COMPOSEAL 30 and 40 meet the engineering requirements of the American Society for Testing and Materials (ASTM) and the Ceramic Tile Institute (CTI). ASTM D4551 is the test standard established by ASTM

“for PVC flexible sheeting which is used with mastic, bedding or coating for construction of concealed water-containment membranes in applications where there is potential for costly secondary damage from water leakage and very long term reliable performance is essential. The tests are intended to ensure quality and performance.”

COMPOSEAL 30 and 40 meet and surpass these ASTM standards.

COMPOSEAL 30 and 40 also meet the CTI requirements for waterproof membranes.
