How to fix a rocking toilet?

[ratter]

Hi all, For a long time we have had a toilet pan that was loose and would rock when you leaned over to wipe your ......., well I assume you get the picture, I intiallt tried tightening the screws but they worked loose quite quickly, I then went and bought a Kinetic Toilet pan screw kit from my local Bunnings and drilled and fitted it. I used the 8mm drill as per the online instructions.

This has made it worse and the screws and plugs are pulling out when the toilet is used and now the rocking is worse.

I have not removed the pan as yet to see what is actually going on, but I feel the concrete is either breaking away or is very thin, thin enough that only the smooth part of the plug is bitting in, not the serated part.
I'm thinkg I need to remove the pan and depending on what the problem is, I may have to break away some of the concrete and use some sort of fill product to repair it.
I will need to use a product that will dry hard enough that I can drill and mount the toilet pan attaching hardware into, so i can secure this toilet correctly.
I'm looking for a recommendation to a product that is available at my local Bunnings

Hello @ratter 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your toilet pan. 

Just a friendly reminder that all plumbing works need to be carried out by a licensed plumber for safety and compliance.

I propose using Earl's 500g Concremate Expanding Cement in combination with Selleys 300g White Wet Area Waterproof Silicone Sealant. The general steps will be to clean the base of the pan and the floor as thoroughly as possible. Fill the mounting holes with the expanding cement and then place a large bead of silicone on the bottom of the pan. Carefully line it up and set the pan down in its original position. While the Concremate is still wet screw the mounting screws into the wet cement without using the sleeve. Spray the base of the pan with soapy water to wipe off the excess silicone. 

Allow the Concremate and silicone to fully cure before re-attaching all the toilet pan connections. This should provide you with a steady non-moving toilet pan. Please be advised that once Concremate cures on the pan screws they can no longer be removed. Another option is to use timber dowels in combination with Selleys 350g Heavy Duty Liquid Nails. The dowels can be driven into the screw holes in the floor in combination with liquid nails. 

However, if your concrete floor is chipping away and is deteriorating, it will be necessary to refinish your concrete floor before you attempt to re-anchor your toilet pan to the floor.

If you need further assistance, please let us know.

Hi Eric
Thank you for your assistance and recommendations, are you able to tell me what is required to refinish the concrete floor, just in case it is bad once the pan is removed?

Hello @ratter 

It depends on how badly it is deteriorating. I would probably ask for a photo of the concrete floor in order to make an assessment. Once we see its condition, we'll be able to make recommendations.

If you need further assistance, please let us know.
