  • Sealing of concrete joints

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.

The base material must free from dust, oil and grease. Any loose material must be removed. Before applying the adhesive, ensure that the ambient temperature and the base material temperature are above 5 °C. Any stagnant water present must be removed before laying the hydrophilic seal strip. Normally, the hydrophilic seal strip is laid in the centre of the construction element when it has a maximum thickness of 400 mm; for greater thicknesses, two strips are required. Hydrophilic seal strips must ideally be glued using VEDA-SWELL hydrophilic sealant. Mechanical means of positioning can also be used.
