Pipe Defect

The renovations to the bathroom involved the toilet being moved to a new location. To prepare for the move, the contractors carrying out the work cut a hole in the floor where the toilet was to connect with the sewer.

When the pipe was fitted in place, it was discovered that this hole was too big. Gapping was left all the way around between the base of the pipe and the floor, extending to a 50mm crack at its widest point.

The contractors wanted a straightforward way to fill the gaps so that the plumbing in of the toilet could be completed with little disruption to the renovation project.

SylWrap Solution

Sylmasta AB Original Epoxy Putty was selected for the application because of its hard wearing, waterproof properties. It was calculated that around 1kg of AB Original would be required and this was delivered to site.

The resin and the hardener were mixed in equal measures and kneaded by hand. The two hour work time of AB Original meant that more of the putty could be mixed in one go without the threat of premature curing. This enabled the contractors to work at a reasonable pace.

Once the putty had been mixed and whilst still soft, it was pushed into the gapping between the waste pipe and the floor. As the putty was applied, it was smoothed off using a little water and a filling knife and left to harden.

Outcome

A full cure was achieved in 24 hours, leaving the crack permanently sealed with a waterproof material sharing similar properties to the bathroom floor.

The renovation was able to continue with virtually no disruption to the timeframe with the contractors also pleased about the cost-effectiveness of the repair.


Follow Up

When the time later came for the installation of a new bathroom floor as part of the renovation process, AB Original was able to withstand being tapped, drilled, screwed, sawed, ground, filed and painted.
