The site is complicated, overall it slopes quite a lot and the detached garage is 465mm above the house.
We are trying to achieve:
- Lower the patio ground levels. I've dug a trial trench around the property and the internal damp now seems to be under control
- Have a multi level patio as the whole site slopes downwards but we want the areas to be usable for a seating area
- Finished surface to be yorkstone pavers which will finish a minimum of 150mm below DPC and floor levels
- All existing rainwater connects to combined waste and BCO has agreed that future rainwater can also join to this as there is no place for a soakaway or any other alternative
- The building is grade II listed and they are very fussy about changing anything in the existing structure but have agreed to allow channel or french drainage
Plan is to make every effort to move the water away from the house and garage.
Looking for advice on drainage and gradients to take the water away from the foundations as much as possible.
