Patio Help & Ideas to solve

[richo106]

Good Morning All

 

I had my patio installed back end of last year and wanted my patio level with the kitchen floor so when I open my bi folds its level (ish), in my naivety and obviously the oversight of the installer nothing was said regarding levels/DPC etc and now I've looked further into this its not right with it being nowhere near the 150mm below required . BC have been round and to be honest it poked his head out and just said nice job and moved. So it's all been signed off

 

Please see attached pictures

 

However I want to make sure I attempt to rectify this before it could possibly cause me issues down the line. The main area that I have any kind of splash up the wall in the rain is the chimney due to it dripping off the top

 

Obviously in hindsight my blues/DPC level would be 2 courses up, I am really struggling with how to rectify this and not look bodged!

 

I don't really want a 150mm deep trench around house

 

So any expert ideas/advice would be amazing on this

 

Is there some kind of render I could put externally? We like the look of this to finish it off anyway but don't know if this could kill 2 birds?

 

Could I take the first row off and install a DPC up the wall?

 

The garage is fine but as these are existing blues they need tidying up and was waiting to see what I did with the rest

 

Many Thanks

Install an aco / channel drain all along the edge of the house. Gravel would also work, and it reduces splashing.

Agreed.

 

Get a consaw and neatly cut a track along the perimeter of the house, and lay a gravel bed say 200mm wide around the house. If you could I would make a full french drain. 

 

If you still notice you are getting water wicking up the bricks from splashing then I would consider applying some silicone brick cream to the bottom few rows. 

 

In any case I wouldn't worry about the inside of the house getting damp as you have a cavity wall.

Is a French drain simply a small trench next to the house wall filled with gravel that allows the water out either sideways or downwards?

I'd do some posh acro drain all the way round, feeding into the drains you've already got. Grout in some nice tile trim prices. Would do the job fine.

That was my initial thought, but it doesn't solve the potential rain-splash issue, and hopefully the patio is sloping away from the house so they wouldn't be taking much water anyway.  Maybe a combination of slot channel drains in front of the doors and gravelled French drains elsewhere would be a reasonable compromise.  Either way, it's going to mean taking some patio up.

Use some geotextile fabrics to wrap the stone in too to prevent them all silting up.
