The article discusses the use of PVC-based polymer waterproofing membranes in maintainable waterproofing systems of foundations. The main properties of polymer waterproofing membranes, which characterize the possibility of their use in such systems, are considered. Examples of objects and conditions of construction sites where the use of maintainable systems is recommended are given (these systems are used in the most difficult construction conditions, and their main feature is the ability to perform repairs during the operation of the constructed object). The process of installation of a two-layer waterproofing system, as well as the equipment and components used, is considered. 2 experiments were conducted to determine the consumption of injection formulations for the repair of sealed cards in a construction laboratory and their loading. Repair compositions based on acrylates ended up in pre-prepared sealed cards with a size of 2x2 m in the conditions of loading. In the future, the parameters of the consumption of injection formulations were measured. Card no. 1 consisted of two layers of PVC membrane, one of which had a textured surface. Card no. 2 consisted of two layers of PVC membrane with a signal layer, between which a separating layer of needle-punched geotextile was laid. According to the results of the experiment, it was revealed that the most optimal is the use of 2-layer waterproofing systems of foundations, with membranes with flat and textured surfaces. This is due to the use (as the top layer) of a membrane with a textured surface, so that the distribution of the repair injection composition under load conditions on the card is the most uniform. The conducted studies also have shown the advantages of two-layer waterproofing systems in comparison with single-layer ones.
