A lake in our back garden

[Dozer 13]

A couple of hard-working craftsmen put it some stone paving in our back garden. It looks great, but every time it rains we end up with a lake maybe 5 feet x 5 feet.

 

I can imagine it will be an ice rink during cold winters, and filled with algae and mosquitoes soon enough.

 

The craftsmen have been out a couple of times pulling up the paving stones and trying to adjust the tilt and angles to get it to drain properly, but no luck.

 

Any idea what they might be doing wrong? Could you recommend someone who might be able to fix it once and for all?

Sounds like it needs a land drain under it to.properly sort it out.

If there are gaps between the paving, allowing water to drain, the it is the water table in the area is above the level of your ground.

 

You will have to adjust your general drainage. (probably)

 

But don't use a diesel powered pump, running on peanut oil, or all hell will be let loose.

Thanks! No gaps between the slabs -- thoroughly concreted. Is that the problem? No drainage problems generally and no problems when this was done in cheap rotting wood.

Most likely. Drill a few holes in the joints between the slabs, and see if it drains away.

 

If it is a solid slab, it should either be slightly higher in the middle so it falls away all round, or slightly higher at one edge, so water runs off.

 

The fall only needs to small, you would not notice it.
