sealing leaking slurry store and dealing with rainwater

JohnBoy

I was with a friend yesterday who has some problems to sort out. his yard is built into a hill with the slurry tank below the yard. The slurry tank hasnt been fully emptied in years (farm was rented, yard still is)

Dirty water is seeping out through the walls and running off across the land.

The walls are old mass concrete which was poured in courses and the water is seeping from some of the joins in the pour.

He's going to get the tank fully emptied for assessment, but what options are open to him? Is there any bitumen type product that could be applied to the inside of the walls or is the only solution to pour a new wall inside the old one?


He also needs to sort out his rainwater, currently gutters run onto the yard and hence into the tank, compounding the issue.

if renewing downspouts and pipework should he put in gullies, or should he run 4 inch pipe straight down, setting an elbow in the concrete keeping any muck out of the system.

There is a sealer that you can get for leaks like that. A friend of mine had a tank poured about 10 years ago and a lot of rain came a few days after. There came a small hole in the lower part of the wall and the tank filled up with water. Contractor drained out most of the water and sealed it with some type of stuff that came in a can like a foam can but it set like resin under the water. Mate is a civil engineer and he was happy with what the contractor had done - said it is stronger than concrete and will last longer. I don't have the name of the stuff but can ask him if you like - maybe someone on here will know the name of it.

would PROTIM be the stuff he used i,ve put that stuff into old walls in houses with damp problems you bore holes into the wall and pump it in . It soaks through and sets like plastic which forms a waterproof barrier .

if there are individual holes in the wall, make them a bit bigger (size of finger) with a drill and put in a rubber bung the type they use when filling the holes after the big shutters 8ft X9ft
