The width todepth ration of ~ 2 : 1 must be respected.Standard dimensions for concrete elements (as per DIN 18 540 / table 3):Joint Distance 2 m 2 - 3.5 m 3.5 - 5 m 5 - 6.5 m 6.5 - 8 mDesign Joint Width 15 mm 20 mm 25 mm 30 mm 35 mmMin. Joint Width 10 mm 15 mm 20 mm 25 mm 30 mmJoint Depth 8 mm 10 mm 12 mm 15 mm 15 mmMinimum joint width for joints around windows: 10 mmJoints must be properly dimensioned as changes are normally no longer feasibleafter construction. Basis for calculation of the necessary joint width are the technicalcharacteristic values of the joint sealant and the adjacent building materials, theexposure of the building elements, their construction and size.Joint Width 10 mm 15 mm 20 mm 25 mm 30 mmJoint Depth 8 mm 8 mm 10 mm 12 mm 15 mmJoint Length / 600 ml ~ 7.5 m ~ 4.5 m ~ 2.5 m ~ 1.6 m ~ 1.3 mSubstrate QualityThe stated values are indications onlyBackfilling:Use only close cell, sealant compatible foam backer rods e.g. high resiliencepolyethylene foam rod.Clean and dry, homogeneous, free from grease, dust and loose particles.Paint, laitance and other poorly adhering particles must be removed.
