What this work involves
Investigate the cause and available discharge options. Coordinate changes with foundations, landscaping and existing services.
- Soil and water exposure
- Drainage or discharge route
- Access and maintenance
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Check that external levels and drainage do not expose repaired facades to recurring problems.
What the drawing needs to explain
Create a defect map with photographs, locations and investigation questions. Include inspection access and the intended drainage path in the repair proposal.
Allow for later maintenance
Use the defect map for later checks. Compare photographs of the same locations so changes are not assessed from memory alone.
Cost factors for this service
Costs depend on site area, excavation, soil and available connections. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for ground & site drainage. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging ground & site drainage?
A drain only helps when there is a suitable discharge route and maintenance access. Have the complete route assessed.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
