Waterstops Day joint bands The pauses during concreting are termed day joints, technical joints, temporary joints. Often due to technical and organisational conditions, the contractor is forced to conduct concreting works in a limited scope. The division of such works into phases is influenced by numerous factors, such as the speed of concrete mix binding, geometric…

Besaflex Besaflex sealing bands of elastic PVC are characterised by many excellent properties, providing savings over a structure’s lifetime. Flexible, soft PVC has been in use since the 1930s, and its properties are subject to constant research. Besaflex sealing bands conform to all standard requirements, thanks to which they are broadly used in the construction industry….

Preparing the bands for installation Before the bands are mounted, they first have to be unrolled on a flat surface and checked thoroughly, whether they are not damaged or deformed in any way. It is not allowed to mount bands that have lost their proper shape. A particularly dangerous phenomenon are deformations of external band anchors, these…

Design rule for waterstops Basic guidelines:   the width of internal bands (a) may not exceed the width of the construction component, (c) bands must be chosen that are not too narrow (greater seal certainty), but also those that are not too wide (due to delamination). In addition, one needs to ensure appropriate installation depth –…

WATERSTOPS Product description The perfection of the process of polymerisation of PVC on the industrial scale has allowed the development of a sealing band manufacture technology adapted to the needs of the construction industry. Knowledge of technical parameters of the material from which bands are manufactured, as well as the conditions of their introduction into the…
