Next to the rotten timber is a concrete pad built a long time ago to prevent a big top loading washing machine from shaking the whole house. This meant that there was a weak spot and water has got in and done some damage.
Today the decay in the laundry floor was cut out.
And the floor sealed then levelled to prevent any future problems at the join between the timber floor and the concrete pad.
The self levelling compound went off a lot faster than expected, so a quick levelling was needed to take of the excess.
A perfectly level floor is now ready for sheeting.
