CLOSED CELL POLYETHYLENE EXPANSION JOINT FILLERBOARD
Description
CORKJOINT Jointflex® is a closed cell, crossed linked, non-absorbent polyethylene expansion joint fillerboard for use in expansion and isolation joints in concrete and masonry structures. Jointflex® is non-absorbent and has excellent properties allowing it to be used in water retaining and excluding structures where potable, salt, chlorine and sewerage water is present.
Jointflex® has no bitumen content and joint sealant can be directly applied on top of it without the use of a bond-breaker tape. Jointflex® is available in standard 50kg/m³ (low) density and is also available in custom densities of 100kg/m³ (medium) and 150kg/m³ (high).
Supplied in sheet form and at a thickness to suit the joint width or can be custom cut in sheet sizes to suit the concrete thickness or width. Also available upon request with a tear-off cap to suit the joint sealant application depth.
