The Challenge
Uncovering the Installation Fault
A Stirling homeowner who had previously hired Maybury Landscaping for excellent patio work in 2024 contacted us again after moving to a new property in Stirling. Within days of moving in, they detected a persistent damp odor that seemed to permeate the ground floor rooms.
Our detailed investigation uncovered that the existing patio had been installed with a fundamentally incorrect gradient — sloping toward rather than away from the building. This critical error was funneling all surface water against the property's walls, above the essential Damp Proof Course (DPC) barrier.
Further inspection revealed no drainage infrastructure whatsoever — no ACO systems, no drainage pipes, and worse still, soil had been placed directly against the building wall. Soil continuously retains moisture, creating permanent dampness that was steadily penetrating the interior structure.

Critical Defects Discovered
- ✗Paving installed above 150mm DPC regulation
- ✗Falls directing water toward property walls
- ✗Complete absence of drainage infrastructure
- ✗Soil packed against building holding constant moisture
- ✗Interior dampness measuring 28.1% moisture
- ✗Property surveyor failed to detect these issues
Our Remedial Solution
Assessment & Ground Preparation
The defective paving was removed to expose underlying layers, confirming total absence of drainage provision. We excavated to 300mm depth creating space for a comprehensive perimeter drainage installation. The DPC position was verified and drainage levels established 150mm beneath it per building code requirements.
Working within fixed ground levels (dictated by surrounding pathways) required precise planning to integrate effective drainage while preserving practical property access.
Engineered Drainage Construction
We installed a block retaining structure 200mm offset from the building creating a definitive moisture barrier that prevents any water from migrating horizontally toward the property foundation.
Inside the 300mm excavated trench, perimeter drainage pipework was laid and connected to existing stormwater infrastructure. We backfilled with no-fines gravel — specially graded stone aggregate lacking fine materials, permitting instant water passage without retention (contrasting with moisture-holding soil).
This dual-protection approach ensures sub-surface channels drain water below DPC level, while surface construction directs rainfall away from the building envelope.
Patio Reconstruction to Standard
We rebuilt using premium Tobermore Heather paving with engineered gradient falls channeling water away from the Stirling property. An ACO linear drainage channel was positioned at the building junction to capture any surface water before wall contact.
All surfaces now direct water away from the structure, with sub-surface drainage providing redundant protection. This represents the only regulation-compliant approach for paving adjacent to buildings.
The Importance of Proper Drainage
- Regulatory Compliance: Paving requires 150mm DPC clearance OR drainage channeling water below DPC
- Material Selection: No-fines gravel = instant drainage (soil = permanent moisture retention)
- Gradient Engineering: Falls must direct away to prevent pooling and frost damage
- Safety Considerations: Poor drainage creates ice hazards during Scottish winters
