Waterstops non Hydroexpansive

SYNKO-FLEX

Non hydroexpansive waterstop for casting joints and impermeable joints between prefabricated structures. Based on bituminous resins. Used to seal horizontal and vertical joints. Suitable for tunnels, car parks, water treatment plants, tanks, pipelines, sewer trunk lines and for any underground work in general subject to occasional or permanent contact with water.

READREAD ADVANTAGES

READREADAPPLICATION
Always ensure that the surfaces where the waterstop is to be applied are clean and dry.
If this is not the case, clean the surface with a wire brush and dry using a torch or hot air drier to remove any dampness. Apply a layer of bituminous Primer and leave to dry. Peel the transparent release paper from the waterstop. Position the waterstop on the surface and press firmly along the entire length of the strip to ensure maximum adherence between the waterstop and the concrete.
Position the second strip of waterstop so that it overlaps the first by 2/3 cm. Press firmly and then repeat the procedure with the other strips. Peel off the brown paper, ensure that the overlaps have been carried out properly (ensure that there is total adhesion between one waterstop strip and another, and between the waterstop and the concrete) and proceed with the casting or apply the prefabricated elements. (N.B: Peel off the brown paper just before pouring the casting to prevent the waterstop from coming into contact with dust or similar elements). If the waterstop has problems adhering to the concrete in vertical castings, warm the Synko-flex strips using a torch and apply a nail to the head of the upper strip. Where possible, it is advisable to apply on fresh concrete.
