Water Main Leak
Islington - London


When a water main ruptured on Upper Street in Islington, residents and businesses (including the home of Foreign Secretary Boris Johnson) were inundated by over a foot of water.

Trustheat were appointed to dry a local listed property and worked closely with the surveyor, the policyholder's insurer and the residents architect who had an extensive knowledge of the property.

Parquet flooring - Dried in situ


With a beautiful parquet floor fitted in the basement, our client was keen to avoid it's removal, especially when only a very small handful of tiles had shown minor distortion to date.

Thankfully, by using evaporation drying we were able to non-invasively dry the solid floor below by drawing moisture out from areas that were not covered by the parquet flooring.

We removed skirting boards, using the porous nature of the lime plaster to release moisture trapped within the structure, therefore avoiding a significant amount of surface removal (and subsequent reinstatement).

Air was drawn in from outside via ducting installed on upper levels, with our system heating the air before it was introduced to the basement.

By using this to create positive pressure, we then ducted the moisture laden air from the room itself, consistently refreshing the internal air mass with dry air to increase moisture release.


5 day drying - minimal disruption


Our drying schedule took just 5 days, and the residents remained in the property throughout, as the ground floor was unaffected by the event.

Monitoring of the drying process in live time showed a fall in the moisture content in the solid floor (and walls at low level) from 99.9% MC to just 10.5% MC in just 5 days, thanks to the efficiency of our evaporation drying solution.

The external trailer houses a boiler that superheats liquid, which is then transferred by insulated pipework.

Internal heat exchangers convert this into high volume, high temperature airflow, ensuring rapid drying.
