Joint Sealant
Joint Sealant
(OP)
Dear Friends,
We have a situation here. One year after constructing a floating pier (40mx15mx2.5m) which floats on to the water with 0.5 m free board, we have bituminous joint seal applied to the expansion joints along the perimeter of the structure that has completely worn out because of the sea water splashes. The top surface of the concrete being only 0.5m above the sea water level, there have been continous sea water splashes leaking into the structure through these deteriorated joint seals (15x20mm). The floating pier is now getting filled with water because of the weak joints and now sinking in water. Can somebody suggest a better quality joint sealant resistant to sea water in long term. Pls help.....

If the aggression is mainly mechanical some will be better but maybe some mechanical protection could be of use. That it may be applied reasonably is other thing.

Do you have a sketch/photo of the floating pier?
RE: Joint Sealant
We have tried using bituminous joint sealer which is failed due to sea water splashes. The sea water has high chlorides upto 45,000 ppm. Polysulphide sealant may also not be suitable. Please find attached the pics and pls advice. How to mechanically protect it? 100% water tight joints is possible?
What is the best material that can be applied on these joints?
Thanks
