Best way to fill the holes left in shuttered tank walls/

johnpawl

Just wondering whats the best way to fill the holes left in the shuttered walls to accomodate tie rods, now that the old snap ties are done away with. Is it a case of just packing mortar in? I've heard that you can buy a plastic plug that you simply hammer in, much like the ones used to attach insulated slabs to block walls. That'd be handy, can anyone shed any light on this?

We used some type of compound in a few holes we had . It was very hard setting . Make sure it gets a good seal ,you dont want the tank filling up with with ground water anyhow . If i remember the name of what i used ill post it up . The fella that poured the tank should have a good idea whats best aswell

when i was working on tanks a few years back we would mix cement water and a rapid hardner into a paste. fillan empty grease container with the mix bodge up a plunger and push through the wall. you need a second man on the inside of the tank with a somthing flat pressed against the tank wall

First I heard of they being done away with; I`d doubt very much that they are done away with as they are a completely sealed job, no need of trying to plug leaks from where the whirly bolts went through

If the whirly bolts were installed correctly then there should be a plastic sleeve left behind in the wall for which you can purchase a proper plug to seal the wall.

I don't know, maybe some people are still using the small shutters and keys and wedges and snap ties, but around here all the contractors are using 25ft shutters with tie rods.. I tried to locate the proper plug but couldn't find anywhere that stocks them...

have a google for "flupp plugs", they are pushed into the plastic liner and in doing so created a water tight seal.......

O.A.P

Easy access in Tuam will have them (093 60470). I dont know where you are though but if you give them a ring they will know where they can be got in your county.

Usually you plug the hole with a plastic/rubber plug and then finish off with a tie hole filling mortar.

Google "concrete accessories" or "formwork accessories" and you will find a few suppliers.

keep going

RMD in waterglasshill in co cork has them but just try any of the shuttering crowds
