Underground structures such as parking garages must not permit even the slightest water infiltration into the concrete. Water infiltration has caused headaches for many owners and contractors. In the case of rainwater wells or underground water tanks, the opposite is true, and no water may leak away. If you choose Bekina BeSealed swellable seals, you can be sure that your underground structure will not experience any moisture problems. Our high-quality swellable strips work actively and immediately seal the construction joints of the concrete in the event of water infiltration. Our patented hydrophilic plugs and rings ensure a perfect seal for spacers and centre pins and prevent concrete cracks.
