Why Poole Properties Need Specialist Basement Tanking Treatment
Harbour-Side Surveys
Specialist basement surveys for Poole waterfront properties. We measure tidal water table variations, test for salt content, assess hydrostatic pressure (often 2-3x higher than inland), and recommend BS8102 compliant systems.
Type C Cavity Drain Systems
Essential for Poole's high water tables. HDPE membranes channel water to perimeter drains and dual sump pumps. Creates breathable void allowing walls to manage salt crystallization while maintaining bone-dry internal space.
Commercial-Grade Sump Pumps
We install heavy-duty dual pump systems rated for continuous operation. Includes high-water alarms, automatic switchover, battery backup (4-8 hours), and remote monitoring options for high-value Sandbanks properties.
External Waterproofing
Where access permits, we install Type A external membranes before internal Type C systems. This belt-and-braces approach provides maximum protection for Poole's challenging conditions. Ideal for new builds and major renovations.
Tidal Table Solutions
Poole Harbour's tidal variations cause water table fluctuations of 1-2 meters. Our systems handle these variations with high-capacity drainage and oversized sump chambers. Prevents overwhelmed pumps during spring tides.
Building Control Liaison
We handle all Poole Council Building Regulation submissions for basement conversions. Structural calculations, fire safety, means of escape, ventilation, and party wall agreements for terraced/semi-detached properties.
Our Basement Tanking Process in Poole
We follow a proven, systematic approach to ensure complete resolution of your basement tanking issues.
Specialist Survey
Comprehensive harbour-side basement assessment. We measure water table depth, test for tidal variations, assess salt content, check hydrostatic pressure, and inspect structural integrity. Written report with system recommendations and tidal data analysis.
Design & Engineering
CAD drawings showing membrane routes, dual pump locations, drainage channels, and battery backup positioning. Tidal water table analysis informs pump capacity. Structural calculations for Poole Council Building Control.
Preparation & Drainage
Strip to bare masonry. Excavate perimeter drainage channels and dual sump chambers (larger than standard due to high water volumes). Install oversized drainage pipes. Repair structural defects. Ensure clean substrate.
Membrane Installation
Install Type C cavity drain membrane to walls and floor with heat-welded joints (more robust than standard for Poole conditions). Create 20mm drainage void. Connect to perimeter channels. Install dual sump pumps with battery backup.
Pump Systems & Testing
Install commercial-grade dual pumps with automatic switchover. Connect battery backup (8 hours minimum for Sandbanks). Install high-water alarms. Load test both pumps. Verify discharge to appropriate drainage (not foundations).
Finishing & Certification
Install battens, insulation, plasterboard. Final moisture testing confirms dry environment. Building Control final inspection. Handover with pump operating instructions, maintenance schedule, and 30-year guarantee certificate.
