In this carpark there were a lot of construction joints leaking. These needed to be sealed for the further use. To repair joints it is necessary to use an elastic filling injection material which can absorb the movements of the joints. Tradecc has specially developed the PC 509 Rubber Acryl which is very suitable for permanent joint sealing. In other cases it can also be required to do temporary sealing with a very flexible, high dense polyurethane foam: PC Leakinject Flex range.
