New Driveway Sloping Towards House

Question

Hello

I've just had a new driveway put in my 1930's semi and in areas it slopes towards the house. We went with a reputable company and apart from the slope towards the house in places they've done a really good job. As it's 1930's its suspended timber floors so I don't want water flooding underneath it and giving us damp and root in the house. The gradient isn't massive, but it's enough to mean water runs the wrong way towards the house in places
We are where we are, clearly lots of issues above. I guess what I need to know what are my options now to rectify this? Couple of suggestions below:
1. Get the company/someone else to angle grind the drive up and retro fit some drainage channels that take the water away (can this be done? how neat can it be done retrospectively)?
2. Fit some sort of thin tile/sloped tile on top of the edging and seal it all like mad so it creates a runaway channel towards the flower bed on the left of some photos
TIA

Hi Ben to be honest  with you going off your description I think the best way to resolve your problem is to put drainage between the driveway and the house and direct it away from your property

Reece · Answer

Install aco channels to allow all water falling towards house to drain away

Hi there,  whenever I install a driveway or patio that slope towards the house or garage I always install Aco Drains so that the water can run into a drain directly or run through away from the  property,  however it isn’t a problem to install the Aco drains after the drive way, with enough knowledge and skill it can be installed neatly and efficiently.   All the best, I hope this answers your questions.  Cristian from CTS Landscapes

You can either put in acco drains up against the house and put the 100 mm pipe into a soakaway at least 5 mtrs away the house or put in land drain across your driveway to direct the water away from your property.

Matthew · Answer

Yes your correct. You could install a drain pipe underneath as they do on permeable drives. A pipe with slits in and fabric wrapped around and tied. you could either have this soaked away into the flower bed or diverted to another one of your drains. Ensure a good amount of gravel around the pipe to help the water go into the without water building up and sweeping through.

If you have no damp course then you could dig down and backwards, either protection paint or a damp liner across the front. If you’ve had block paving this isn’t to hard of a job.

But there are several solutions to your problems. Pictures would help with an assessment and what needs to be done.

It’s just old material for the job normally .ie 
Bricks concrete stones

Retro fit some aco drains that flow into the nearest downpipe. Simple job that should only take one day. Whilst I appreciate you are happy with the job the builders provided, they should have taken into account the drainage which means they should technically come back and do the labour for free

Hayley · Answer

I would recommend aco drainage sponge front elevation 150 mm below DPC as a level point to receive the excess water and run into a 100 mm pipe work to a suitable soak away positions

Regards the damp and rotten sub floor 
Ensure you have plenty of air bricks 
If it’s being starved of air to front elevation explains current condition

You could also treat the ends of the joists with a timber preserver to help any damaged areas 
Allow floor to breath will also help

Firstly what type of paving it is and how the base and subbase has been made up has a lot to do with getting rid of water through the ground, so if it build up on hardcore and laid on sand, then open grade stone and gravel is lots better for removing water.

Second as the natural slope, by the sounds of it is towards the house and if no option to reverse this, when an aco drainage channel should be installed and connected to drain.

Get the company or someone else to  fit some drainage channels / drainages pipes that take the away from the property and in the right
 manhole drain system
