Good patio drainage not only has to function reliably, of course, it should not disturb the overall appearance of the terrace. We'll show you a solution, how to hide the expiration, but can easily be reached if necessary.
Poorly placed drainage channels can spoil even the most beautiful terrace. What is closer?, than not taking any risks at all and letting the drain disappear completely under the terrace. In our case, this solution is almost obvious, because the terrace is divided into a paved area and a wooden deck. However, it is important for all hidden variants, that the built-in drainage channel remains accessible for cleaning the filter.
The channel itself is made of so-called polymer concrete, which is also designed for higher loads such as under driveways. The elements can be combined with each other without additional connecting means and can therefore be plugged together to virtually any length. What you always need for this channel system, is a drain, which directs the water to the canal or into a cistern. This drain must be a #100 plastic pipe, you can use the corresponding accessory sockets or an inlet box (for horizontal connection) connect to the gutter. So before you start, Redesign or remodel your patio, you need to plan and lay the drain pipe.
1 The 25 x 50 cm large paving slabs are inserted vertically along the measured step . Lean concrete bite. The drainpipe leads either into a cistern or directly to the sewer.
2 Die Rinne mit dem Abzweig nach unten setzen Sie auf die Rohrmuffe. The groove on the underside of the channel fits exactly on the 100 pipe.
3 Die Rinnen verbinden Sie per Stecksystem. The following sections are only inserted into the previous ones from top to bottom.
4 Sollten Sie Rinnen auf Maß zuschneiden müssen, so use a cut-off grinder with a stone saw blade.
5 Die Fläche unter dem späteren Holzdeck legen Sie mit Gehwegplatten aus. Lay them on a 10 cm sand bed with a slope of 2% towards the drain. The wooden substructure will later be screwed to it.
6 Beachten Sie beim Aufbau der Holzunterkonstruktion, that it does not run down the drain channel in one piece. Break up the sticks, so that the channel remains accessible. Do not screw the short pieces of wood together.
HOW TO REACH THE CHANNEL.
The last two Bangkirai planks of the wooden deck are bolted to a separate short substructure, which rests on the drain channel. That allows you, to remove the two as a whole from the top surface. The cover grille of the drainage channel can also be removed without any problems. You should regularly clean the filter on the branch and the gutter itself – at least twice a year – clean and rinse.
