Watertight terrace on stilts

This is an exceptional work of wood:
- It's a terrace on stilts, at an unusual height: 4 metres,
The span between the columns is quite large, which has led us to use very large cross-section load-bearing beams,
- We produced a made-to-measure balustrade in Moabi (an exotic wood), prefabricated in the factory,
- There is a large staircase with a landing and a stainless steel balustrade.

General view of the terrace

Creating the structure

General view of the terrace — 1 : This is a very beautiful waterproof terrace.
This terrace is watertight thanks to the use of our Metadeck aluminium profiles (watertight decking for wooden terraces).
The staircase is also watertight thanks to a sheet of polycabornate.

Creating the structure — 2 Construction of the structure (posts in Douglas fir, joists in class 4 treated pine)

Installing the profiles

Metadeck profiles

Installing the profiles — 3 Installing the Metadeck profiles. We let them overhang, and cut them with a plunge saw on a rail, to get a nice straight cut, especially for the angled part.

Metadeck profiles — 4 The profiles are almost in contact with the millstone wall. We treat the seal between the wall and the profile afterwards.

Waterproofing treatment

Connection to the door frame

Waterproofing treatment — 7 Illbruck SP 925 thixotropic mastic for waterproofing all single points. The sealant remains flexible at all times.

Waterproofing

Invisible channel

profiles for waterproof terraces — 9 : Progress in the use of profiles for waterproof terraces

Invisible channel — 10 We created an invisible gutter to collect rainwater. This gutter is located under the deck boards. One board is removable, mounted on metric screws and inserts to allow maintenance of the gutter.

Creating the channel

Installation of the cheneau

Creating the channel — 11 Building the gutter. We created a timber-framed gutter shape and sealed the gutter with an EPDM membrane. It's totally reliable, easier to install and more economical than folding zinc.

The entire structure above the gutter and EPDM is protected from splashing with butyl tape.

Finishing touches

underside of watertight terrace — 14 The underside of the waterproof terrace is perfect because the profiles are powder-coated white in the factory. It's maintenance-free for life.
