Bekina BeSealed’s swellable sealing products are ideal for waterproofing manholes. Our hydrophilic swelling products are known for their high user-friendliness and quality. Our swellable strips can be used to seal manhole construction joints. For manholes made with prefabricated segments we have narrow sealing inserts that can be placed around the segments. At the slightest water ingress, these sealing inserts swell automatically, creating the perfect seal for the manhole.
