dura.®cord is a semi-rigid joint filler used for forming expansion joints or as a backing material for joints in:
- Retaining walls.
- Deck slabs.
- Highly flexible and compressible.
- Excellent recovery properties and tensile strength.
- Rot proof.
- Fine closed cell structure.
- Low load transfer.
- Bitumen free.
dura.®cord should be compressed into the joint to approximately 70% of its original size. Where hydrostatic pressures are present, compression should be to approximately 40% of its original size.
For most effective results, dura.®cord must be inserted into the joint to a depth that will accommodate the depth of sealant speciﬁed i.e. joints from 6 mm to 12 mm wide, width and depth must be equal. From 12 mm wide to 24 mm wide the depth should be 12 mm, and for joints over 24 mm wide the depth should be half the width.
dura.®cord is supplied in continuous rolls in various diameters from 6 mm to 50 mm.
Handling & Storage
