During heavy downpour, the soil beneath the driveway keeps chipping away. Please can someone advise a cheaper solution to this?

Scoring of subgrade :
Scour highly reduces lateral soil support and Lateral soil support is very essential to bear maximum bending stress.
When the ultimate lateral pressure is lower then it was caused by decreased vertical effective stress and indirectly decreased the initial modulus of subgrade reaction.
How to reduce scour in subgrade :
Here I am discussing some points, through that we can easily reduce scour in the the the subgrade, they are as follows;
I hope so your doubt is clear.
Welcome to theconstructor.org . I understand your requirements.
The most economical method of compacting is uses of bamboos and root fibres in the soil which makes it steep compact and highly tensile resistant.
Scouring of subgrade:
The soil which is in under the driveway is being further complicated by the weight of a killer passage and parking over and on its surface as well.
Does soft ant bite the heavy downpours of rainwater which permits through the drive phase surface which neither diverts the rainwater away from its accumulation on the surface nor provide a sufficient subsoil Foundation to prevent the compaction process.
But unfortunately, the reason no 3 as well as adequate and one of the permanent solution which prevents this type of software and compaction erosion of the underlying driveway surfaces soil without the following terms:
The soil under the driveway is being further compacted by the weight of vehicular passage and parking over and on its surface. Softened by the heavy downpours of rainwater permeating through the driveways surface which neither diverts the rainwater away from its accumulation on the surface or provides a sufficient, subsoil foundation to prevent compaction. Unfortunately there is no cheap, quick and permanent solution to preventing this softening and compaction erosion of the underlying, driveway surfaces soil without :-
The most common cause of driveway erosion is flowing water. If rain water from the downspouts of your house is directed to flow down the driveway, divert it. Water tends to flow along the sides of the driveway causing soil erosion. Still, you have water direct from rainfall. The best driveway erosion ctrl soln is to have a permeable paver driveway with necessary edging.

Road shoulder, which is an important of the road, should be provided to protect the road from water ingression, and it also serves as lateral support for the road, parking area for disabled car is it is wide enough, and it prevents edge-drop of cars. Fig. 1 may be a cost-effective way to construct a road shoulder but it may not be the best way.
