Hi have question that I don't seem to be able able to get a straight answer to.

I am renewing a patio that didn't have drainage, but is prone to flood during heavy rain, especially as we are on clay

I'm going to installing a linear drain, to cope with the amount of water.

Should the patio slope away from or towards the house ?

Thanks

Matt

Always fall it away if you have the choice. You should only ever fall it towards the building if there is some reason why falling it away is not possible.

^^ away is always best
if it falls away no need for linear drains as the lawn can drink the water
1:60- 1:180 depending on flags/slabs

It would also depend on the amount of soil you have to move to make it a viable option

Installing a linear drain is all well and good, but to where is it connected?

Over the last couple of months I've seen/been shown three jobs where a linear channel was plonked in at the boundary of a patio or driveway and connected to nowt, with the assumption that the collected water somehow is magicked away once it enters the drain.

And as LLL says, if it's not a massive patio (say <50m²) and the ground isn;t too heavy, it's likely that the garden would absorb the run-off.

Alternatively, have a look at the Pavement Edge infiltration drain

Thank you everyone for your advise, it is greatly appreciated.

The lawn/garden is above the patio area, hence the need for drains. I will be connecting the drains to the existing surface/storm water drains, that have been identified.

I'm no afraid of hard work so will be digging out the soil to ensure the fall is away from the house.

Cheers

Matt
