Sika Expansion Joints For Concrete Walls

Standard joint widths for joints between concrete elements.

Sika expansion joints for concrete walls.

Emseal is a leading innovator and manufacturer of premium sealants and expansion joint systems for the commercial construction industry and many specialty market applications. A width to depth ratio of 2 1 must be maintained for exceptions see table below. Sikadur combiflex sg system or sika dilatec system are post applied tape systems adhered with epoxy resin onto the membrane providing an ideal solution for construction and expansion joints in particular to seal joints of precast components. The joint width must be designed to suit the joint movement required and the movement capability of the sealant.

It is used for the installation and repair of joints in concrete slabs and concrete screeds in car park decks garage floors ramps storage areas production halls and hospitals. For joints in floor substrates which have to withstand a lot of different stressors we developed innovative pre fabricated panel systems called sika floorjoint. For green concrete applications control joints must be cut 8 hours prior to sealant installation and in expansion joint forms must be removed 4 hours prior to sealant installation. Emseal is a leading innovator and manufacturer of premium sealants and expansion joint systems for the commercial construction industry and many specialty market applications.

The joint width shall be 10 mm and 40 mm. For wet concrete applications all excess or standing water must be displaced and concrete must then dry for a minimum of 60 min prior to sealant installation. Sikadur combiflex sg system or sika dilatec system are post applied tape systems adhered with epoxy resin onto the membrane providing an ideal solution for construction and expansion joints in particular to seal joints of precast components.
