Hotel basement conversion

We have completed a hotel basement conversion for a 17-bedroom hotel, located adjacent to the promenade, which had an unused basement, extending under the entire footprint of the building. The hotel basement was damp, smelly and virtually unusable, despite a previous attempt to ‘dry line’ the walls. It is likely that the basement area was originally used as a bakery, as an oven was uncovered during the conversion works, which extended under the hotel car park.

The hotelier wanted to make use of the basement space to provide a new location for the hotel bar and provide two private bedrooms.

The basement conversion

The initial work involved clearing the site of existing hardboard and timber battens, which has been used to hide underlying damp problems. The project was carried out in stages to enable the owners to use parts of the basement while the conversion was in progress

Waterproofing was achieved using the Oldroyd Xv Clear Cavity Drainage System. An Aquadrain Perimeter Drainage Channel, leading to a sump chamber and pump, was first installed around the perimeter of the basement to provide additional drainage capacity at the wall-floor junction. Oldroyd Xv Membrane was then fixed to the walls using special, self-sealing fixing plugs. Joins between sheets of membrane were sealed using special sealing tape. Oldroyd Xv Membrane was then laid across the floor, ensuring an overlap with the membrane already fixed to the walls.

This system was chosen for a number of reasons:

  1. No wet trades involved, allowing basement to remain in use while works in progress.
  2. Allows waterproofing to be carried out in stages, giving areas of the basement to continue to be used during the conversion.
  3. Suitable for application directly onto brick walls with no surface preparation.

After the Oldroyd Xv Membrane had been installed, wooden battens were screwed into the fixing plugs to secure the membrane to the wall. Plasterboard was then fixed to these battens, providing a smooth finish for decorating. The gap between the plasterboard and the membrane allowed electrical and plumbing services to be hidden.

The finished hotel basement conversion

The relocation of the hotel bar to the basement provided a huge increase in dining capacity and an improvement in bar facilities.
