Underground drainage systems have been used for centuries, but until early 1990, consisted of no more than a pipe drilled the idea of Victorian porous clay pipe (or tile drainage), often cease-French, French after Henry know that the idea took place after the Great Britain of New England in 1856.
Include modern derivative of the French drain for many different profiles are flat, allow to put under the floor, but above the base, which protectsTheir cover-up announcement constipation, a common problem that the old tile drain systems in question. And 'generally considered a good idea to keep the drainage system at this level for this reason. It 'also good practice inspection doors for maintenance and repairs. For a visit to the port to be effective should be more than a 50 mm diameter tube connected to the system. Ports around 150 mm in length and 50 mm are better than one that can see inDrainage channel and effectively use a hose for cleaning, if necessary. Some designers have a special "port area", access in both directions along two walls of the place that combines the functionality of a corner and two doors that would be required in a system include allowing for example, less imaginative. The "telescopic port 'port allows the tip of the wire flattened to the ground, which can be a problem with the doors static head.
The drainage channelAlways have the holes to water them. It 'important to ensure that the holes smaller than the size of the stones surrounding the channel are usually otherwise the stones and the water flow. Some new projects are circular or oval holes are replaced with narrow slits to avoid this problem.
The output from the drainage channel should be sufficient, the flow of water when it leaves the channel and into the bottom chamber. This is aError, tube diameter 50 mm, as the output of a system of canals, as much water as a "4 tubes can provide you with a diameter to be used. This seems like common sense but it is a common mistake.
Many modern systems include a vertical flange, so that any surface water run along the wall in the system. To this end must be the back part of the flange must remain open, but there is a growing body of opinion against this practice. Open secured flanges allow water vapor andmicrobial spores and odors in the room to vent the radon gas, if the property in an area affected by radon. Emptied with a damp wall in the system is healthy, as it helps to shape the atmosphere and humidity in the cellar and the house above. It is best to practice with a flange sealed, and if there is running water along the wall, hide them with a proper vapor barrier membrane.
Finally, a plastic channel that constantlyAble to develop a microbial slime wet and not healthy and can lead to a restriction of water flow. It 'a good idea then, an anti-microbial additives such as silver nitrate contained in the plastic used in production.
So in conclusion, the features include top mounted telescopic angle inspection openings, a wide grip, an output channel with a slot instead of holes and sealed in a flange connection with a wall-membrane is used.
