Case Studies

National Galleries Case Study

The Probelm
We received a call from Bill Darling of the National Galleries of Scotland in Edinburgh enquiring if we could help them out with water ingress into the building. After further telephone calls to Bill and his plumber Bill Fordyce, we received the relevant information that was required for us help.

The reason for water ingress into the Galleries was a hole in the lead rain water conductor pipe. This lead rain water conductor pipe takes the water away from part of the Galleries’ roof. The plumber had tried all sorts to try and stop the water leaking into the building, but was unsuccessful. The area where the lead pipe was situated was inaccessible and also contained very expensive paintings.

One painting alone was valued at £50million and this was only on loan to the Galleries. So we were under immense pressure not to make any mistakes. We also only had one window of opportunity to carry out these works as the weather forecast was for heavy torrential rain.

The Solution
Bill Darling and Bill Fordyce were in a predicament. They asked if we had any thing that could repair hole with minimal disruption.

After telephone conversations with our Drain Lining counterparts (Brawoliner) in England and Germany, it was decided that the best way to tackle this problem was to use our Flexi Drain Lining Sock. Engineers attended site and works were carried out to the complete satisfaction of the National Galleries.

The Outcome
That night as forecasted the rains came and the Galleries were dry, and the works were carried out with minimal disruption to the Galleries and public.

Lorne Hotel Case Study

The Problem
Powerrod Drainage was called by Logical Land Developments Ltd to the Lorne Hotel in Kelvinside, Glasgow to investigate a drainage problem the hotel had been experiencing. The hotel has been going through a £7 million upgrade.

The Solution
Various drainage companies had been to site but were unable to detect why the drainage system kept blocking. Powerrod Engineers used high Pressure Water Jetting on the internal drainage system and Drain Tracing techniques to locate the flow of the drain.

The drainage run was located to an external manhole chamber on the pavement. The manhole chamber was over 5m deep. Due to the depth of the manhole chamber, Confined Space Manhole Entry Equipment was required to enter the chamber.

Engineers entered the Manhole Chamber and removed an internal access cover which had fallen into the drainage channel and was causing the blockages. Once the access cover was removed, the drain was High Pressure Water Jetted and the drain was restored to full flowing capacity.

The Outcome
Works were completed to the time scale given and Site Manager was pleased with the result.
