Basement conversion and waterproofing
waterproofing method
Waterproofing regime
Type C – Drained cavity protection
Midland Tanking designed the basement conversion waterproofing, taking into account the substrate, age, condition and desired usage for the cellar. The most reliable form of waterproofing for this basement conversion was an internal cavity drainage membrane (CDM) system.
All walls and the floor were lined with a cavity drainage membrane (CDM). These membranes were linked to the sump chamber via perimeter channels. Within the sump are two pumps and a high-level alarm. This system is designed to catch any water, direct it to the sump and discharge it automatically. Flushing and maintenance points were installed to allow future servicing of the system.
The design was conducted by Midland Tanking’s Structural Surveyors in Structural Waterproofing (CSSW) and installation undertaken by qualified technicians in accordance with BS8102:2009
All waterproofing materials were supplied by Triton Systems Ltd
Ventilation
Proper ventilation is paramount in a basement conversion due to the unique challenges posed by underground spaces. Basements typically have limited natural airflow and can accumulate excess moisture, which, if unchecked, may lead to mold growth over time.
Effective ventilation systems ensure that stale air is constantly exchanged with fresh outdoor air, reducing humidity levels and preventing the buildup of harmful pollutants. Additionally, adequate ventilation helps regulate temperature extremes, making the basement space more livable year-round. Midland Tanking installed a ventilation system in this basement to allow for a living space and wine store.
