Splash Strips On Small Patio

[jsmac]

Hello,

I am undertaking my first attempt at paving a 9 sqm area in front of our house with clay pavers. The area was paved with concrete about 30 years ago directly onto the soil and abutted right up to the house. As expected the concrete cracked as it settled over time and did a very poor job of directing water run off away from the house. I have removed the concrete and excavated about 20cm of soil. Within only a week the masonry where the concrete abutted the house and the coal cellar has dried noticably and the soil itself is significantly drier.

Seeing how well the masonry of the lower ground floor has dried out I am minded to install splash strips along the short length of where the new patio will meet the house/coal cellar. However, the water outfall points are on the other side of the coal cellar so there is no convenient place to direct the perforated pipe. The boundary wall is only 2.7m from the house.

Is it viable, or indeed sensible, to run the perforated pipe towards the boundary through/under the sub-base and terminate it 2.5m(ish) away from the house?

Will the relatively small amount of water that is collected in the perforated pipe be safe to runoff under this small patio? Am I overthinking this? Any thoughts or recommendations would be most welcome.

Many thanks.

not sure what splash strips are?
linear drains against the house and a small soakaway will do no harm
what is the subgrade?

Thank you for your reply, LLL.

The subgrade is chalky soil. In some places I needed to break through a layer of chalk to drop the ground levels enough.

By splash strips I'm referring to this article - https://www.pavingexpert.com/splash_strips. I have basically done what is described in the article. 10 - 20mm pea shingle was the best material available locally to fill the 400mm deep trenches so that is what I've used. It's reassuring to know that a small soakaway as I proposed won't do any harm.

Thanks again.

ahh the classic "french Drain" bodge

probably too late but linear drains to a soakaway do a better job

but if you are on chalk drainage should not be an issue

best
