I'm setting the slope for my paving job and have a question. In the attached jpeg Level A represents the finished level around the perimeter of the house. Level C is the lowpoint in the whole lot with Level B being intermediate between A and B. There is a fall from A to B to C so rain will fall off into lower level garden.
In the diagram should I have Pt 2 at the same level as Pt 1, or should I have a linear fall all the way from Pt 1 to Pt 3.
It is to scale. Across the narrow width of the pathway is 1.2M. It's a drawing of my patio at the back of the house and the footpaths. The long narrow section is to the side of the house.
Pt = point as in position.
Linear means in a straight line (not a level line) so it would be a consistent fall all the way, as opposed to different falls along the length.
Ok I understand I was thinking it was a driveway. Because the side passage is so narrow it doesn't matter if it doesn't fall at the same angle as the main body personally I'd Install the main body at the best height possible and as long as the water was getting out of the passage then I'd be happy.
Ok thanks...just thought there might be an established way as this shape is so common, at least in my neck of the woods. There's no problem with sufficient fall either way. Just with one way there is a more severe fold across the width of the path at Pt 2.
At the risk of confusing things further the diagram below (not to scale) shows a side view at path level looking at the side of the house. The red line is Level A, the Blue is B and C. You can see the fold at Pt 2 in Method 2.
