Hi, I have a depression in my asphalt driveway next to my house, with the low point situated only a few feet from the foundation.
When it rains heavily, the water ponds here and eventually overflows, dispering into the soil which lines the rear side of the house - far to close to my foundation for comfort.
Over the years, the grade has shifted towards my house such that there remains no easy way to regrade away from the foundation without infringing upon my neighbour(shared driveway).
I have considered installing a drainage pipe(french drain) to divert the water away, but since the soil on the property has a sand-like consistency it has been suggested as an alternative that I drill holes into the low point of the ashphalt(where the water is collecting) to help facilitate drainage into the sand below.
Is this a sound suggestion?
If so, what diameter holes would be recommended to best expidite drainage, whithout needlessly underming the location.
After drilling the holes I had planned to stage a trial run with a garden hose(to approximate rainfall), and assess their viability.
But I have lingering concerns as to whether the depression's proximity to the foundation allows sufficient clearance from the foundation to be advisable.
Also, I remain skeptical as to what adverse weathering effects might be exposed through the perforations as a result of the climate(-30 C. winters up here).
Lastly, should I so desire at a later date(for whatever reason) after drilling the holes, would I then be able to patch them up with a simple pot-hole filler(that you buy at the local hardware store) without worry?
Comments and suggestions are appreciated.
