Waterproof membranes, waterstop strips, hydrophilic seal strips, waterproof expansion joints... All waterproofing products for expansion joints.
WD WATERPROOF JOINT
Special waterproof expansion joint suitable roofs and car parks. Very flexible, suitable for use with hot asphalt. Compatible with PVC, EPDM and other waterproof membranes.
EPDM-S membranes (ethylene propylene diene monomer) is made from rubber of superior quality. They are used for waterproofing expansion joints. Economical, easy and simple to apply, very flexible and elastic, the EPDM-S membrane is ideally suited for expansion joints.
"The VedEPDM EP 95 adhesive is intended for bonding and joining plain-surface EPDM membrane (EPDM-S).
VedEPDM EP 95 is a solvent-based contact adhesive of high strength suitable for fast application. It is specially formulated for application by roll and /or broad brush. The time it remains tacky allows its application once to large surfaces."
A & AA WATERSTOPS FOR CONCRETE CONSTRUCTION JOINTS
Waterstops are made of elastomers of different characteristics. They are available in nitrile or flexible PVC (Vedaflex). Nitrile waterstops are characterised by a higher breaking elongation, excellent resistance to chemical agents as well as to ageing, and permanent elasticity that is comparable to that of rubber. Welded joints are very easy to produce. Flexible PVC waterstops are made from basic raw materials of high quality, but offer an economical solution.

HYDROPHILIC SEAL STRIP
The hydrophilic seal strip ensures the waterproof qualities of construction joints in buildings and as well as in the ground, in contact with water, whether pressurised or not. It is used in concrete construction joints by acting as a barrier to water seeping through. This waterproof performance is achieved by the swelling of the strip cast in the concrete when coming into contact with water. The swelling against the contact faces surrounding the strip produces a pressure between the strip and its enclosure that prevents the water seeping through the joint. The strip swelling is reversible. In other words, the strip expands in contact with water. In the absence of water, it dries out and regains its original shape.
VEDASWELL HYDROPHILIC SEALANT
VEDASWEL Sealant is a hydrophilic waterproof sealant that can be applied in a wet environment. Supplied in cartridges, it is applied using a normal sealant gun. By doubling its volume when absorbing water, it provides an excellent waterproof performance without even losing its elastic properties.
FDJ JOINT BACKING
In accordance with relevant standards (French SNJF and ISO), the joint backing is a material that is laid to limit the depth of the sealant in the joint and to define the back profile of the joint. It stops the sealant from adhering to the three faces of the joint and helps to resist the pressures that occur when apply the sealant. The joint backing must not have any effects that will change the physical and chemical properties, and even the appearance, of the sealant. It can eventually serve as a barrier to separate the sealant for chemical attacks from the bottom side of the joint.
VEDAFLEX SIL is a one-component silicone sealant of low modulus of elasticity and neutral cross-linkage. It vulcanises in contact with atmospheric moisture and forms a rubber that is extremely flexible and resistant. Non-corrosive, it does not produce substances with a strong odour. VEDAFLEX SIL has the SNJF mark as a 1st category product for use on glass, aluminium and concrete without primer.
"Veda's butyl strip is a cold adhesive strip made up of an adhesive butyl backed by an aluminium-reinforced polyester film. The adhesive face is protected by a peel-off silicone backing and offers an excellent tear resistance. The butyl strip provides a water and vapour barrier. It is recommended for the repair of membrane tears or holes as well as the protection of mechanical joint anchors."
Pure epoxy resin sealant for use on reinforcement bar in concrete construction joints and for different bonds. Easy and quick to extrude. Very strong bond.
