* Remember the area of ground that is now covered with this non porous
material used to soak up the rain, and now it doesn't.
* There are many ways of dealing with water landing on a courtyard, but the
most common is a pipe grate drain.
This is usually inconspicuous and is
set in a position that will most benefit the catchment of water, usually the
surface is levelled in a way to direct the water to the grates. These are
usually plumbed into the stormwater, only if the stormwater has an open
end. If not, then the water will have to be piped somewhere where it will
do some good and not damage the ground through erosion.
* If the court area has an edge that will allow the water to flow off onto a
garden or grass, great, but keep an eye on any erosion problems that
* Fixed grates are not really suited for gravel courtyards so it is best to use
an agg. line or slotted stormwater pipe. This is usually set into a trench
deep enough so as not to be damaged by walking on it and covered with
the gravel so it's not seen. This is then plumbed into the stormwater pipe.
* Multiple lines can be placed in, the same way as above where there is a
chance of a lot of water.
