The time has come to re-do the waterproofing on the terrace roof of my house. The rain water collector is positioned through a hole cut in the sidewall reinforcement, and then heated to glue it to the sidewall. Applying the insulation requires careful attention to the weather forecast and the planning of the work. Last drops of the weekend’s heavy rain. Welding the outer reinforcement onto the collector.

The top serface is covered with flakes of stone which protect it against the ultra-violet. The joint of the flat roof and the rising elastopene that surround the roof are a possible source of leaks. Finishing around rain water elastohene See 2. Creative Commons Attribution – Flan 3. Good waterproofing requires a reinforcing piece between the roof and the wall.

Reinforcement at junction of standups. The second bitumous layer is of the same material as the first. Heating the outer-reinforcement and the collector.

For example the first layer could be omitted, and the insulation glued directly to the existing surface. L’isolation Knauf Thane ET. Bitumous glue is applied to the rising side walls. Finition autour de la platine. Soudage du renfort sur platine et dalle. On my roof, the rolls of the final layer are positioned north-south, so the second layer must be east-west. The orientation of the second layer depends on the way in which the third layer will be applied.


Fitting the 2nd layer in front of the future rain collector. Pas une goute n’entre dans la maison. Rodolphe Ferracane, e-mail contact AFR-etancheite. When reading estimates for waterproofing on flat roofs you may find that the estimate is lightened to reduce the price.

La partie bitume fait approximativement 2. Removal of remnants of previous waterproofing. Click on photo to enlarge. Before the insulation is laid, the channels carrying the rain water are reinforced: If there is a risk of rain, then the Knauf Thane ET glued to the first layer must be entirely enclosed by the second layer, even if this means performing work not needed by the final waterproofing.


The weekend brings heavy rain to test the waterproofing — not a drop gets through to the house. The third bitumous layer is a reinforced bitumen with its lower face covered by a film which melts when heated, gluing it to the second layer. These are ajusted now but will be fitted later taking into account the future height of the finished surface. The first layer, which provides the waterproofing, is of elastic bitumen, 2. This second layer of bitumen should be placed on the Knauf Thane ET within a few hours to ensure that the Sopracolle elaetophene speads out under the pressure of the layer of bitumen above.

The work specified by this standard is often referred to as Three layers plus insulation, with heated reinforcement. Creative Commons Attribution – Pas de Modification 3. Click on figure to elastohpene.

The collector is trimmed before applying the outer reinforcement. As with the 1st layer, the joint of the flat roof and the rising walls that surround the roof are a possible source of leaks.

The two layers should be perpendicular to one another. The photos on this page describe the work.

It prevents water vapour reaching the insulation, and serves as a falm for the finishing layer. The Elastophene 25 is rolled out and cut to fit.

Click on the photos to enlarge them. Cutting nord end of a roll of finishing layer.


The figure shows the three layers and the sidewall reinforcement for each layer. Before work begins, the existing concrete surface was cleaned with a high pressure bar hose equipped with a rotating jet. Cinq points de Sopracolle par plaque.

Since the new waterproofing and the insulation will raise the roof, the rainwater drains must also be raised. The rain water collector will pass through this. Chauffage du sur-renfort et de la platine. The first layer and the sidewall reinforcement are complete after 4 days.
