Manhole gasket Top-Seal Plus CXThe integrated seal for the Econorm manhole system with integrated load transfer element filled with silica sand as per DIN V 4034-1 and PAS standard 1004.Benefits:•The Top-Seal PLUS CX is integrated directly in the socket during the production of the manhole rings and is held securely in the concrete by multiple anchors.•The integrated sand tube serves to transfer vertical loads.•Infiltration of water of the manhole ring socket is excluded by the position of the anchor feet at the Top- Seal-PLUS-CX gasket.•The Top-Seal PLUS CX is produced as a hard/soft combination with the co-extrusion method. This method has considerable advantages: oOptimal concrete compaction even behind the seal by the hard formwork element.oAnchors made of hard elastomer guarantee the secure fit in the concrete.oSand tube made of hard elastomer optimises the load transfer properties.Top-Seal-PLUS-CX are subject to constant inspection by independent third-party institutions. They comply with the requirements of EN 681-1, QR 4060 (FBS quality guideline), PAS standard 1004 of the Econorm manhole system as well other applicable quality standards.Assembly:After the spigot and the socket were cleaned, the necessary lubricant Cordes-GM-95 is applied liberally by hand to the spigot of the manhole ring. Then place the manhole ring in a centred position.There is no need for any additional load transfer elements as required by DIN 4034-1. The load transfer element is already integrated in the seal. When the seal is installed on the spigot, the load transfer element will automatically reach its correct position.
Material:The Top-Seal-PLUS-CX material is fabricated from styrene butadiene rubber (SBR) and ethylene propylene diene rubber (EPDM). The use of these materials has proven its worth in rainwater and wastewater applications due to their excellent sealing characteristics.
