Timber decking using TD supports, Genesis Homes, London

This project was a refurbishment of an existing building, where the waterproofing membrane had been completely replaced. There was a large roof deck built to a fall and several small terrace areas.

The contractors were keen to ensure that the soft timber was raised off the deck to prevent rotting, and also wanted to ensure that the larger fall across the roof could be arrested so that the finished deck area was completely flat.

Wallbarn TD adjustable timber decking support pads were the ideal solution.

The supports were loose laid onto the deck without fixings (as this might compromise the waterproofing), and timber bearers were laid onto the headpieces, housed in between the positioning pegs to prevent movement.

Wallbarn recommends that the supports are placed at a maximum distance of 600mm apart. If high loadings are to be placed on the decking, such as Jacuzzis, then supports will need to be even closer.

The joists were placed down in runs, and then cross beams were fixed to give a secure, stable grid framework. The contractors were able to wind the stems of the support pads up or down to create a completely flat level, using a spirit level as they went.

Once the frame was down, the decking planks could be fixed very quickly. It is recommended that installers always used galvanised wood screws.

A superior finish was created across the whole area. The decking was flat, true and secure, and strong enough for planters, benches and other features to be installed on top.

The contractors estimated that they were able to construct this timber decking twice as fast than by using the other method they had used in the past.

The roof and balconies were constructed in an identical fashion.
