Description
ECA Flexcell is a versatile, preformed board composed of high-quality natural wood fibers impregnated with 10% to 20% bitumen. These fibers are combined to create a compressible, non-extruding board used to fill expansion and isolation joints for in-situ and pre-cast concrete construction.
Uses
- Serves as a joint filler in highways, airport runways, and bridges
- Functions as a protection board for waterproof coatings and membranes
- Ideal for structural isolation joints
- Used as an expansion joint filler in concrete pavements, walls, and elevated slabs
