Basement Waterproofing for the University of Manchester


The Sackville Street Building is a building on Sackville Street, Manchester. Construction began in 1895. In 1927 plans had been drawn up to extend the Sackville Street Building, however, plans were placed on hold due to World War II, the expansion was finally finished in 1957.

The Sackville Street Building, along with many other buildings owned by the University, is now classed as Grade II-listed and has been home to the study of science, technology and engineering at the University of Manchester for over 100 years.

The opulent main entrance on Sackville Street gives access to the Entrance Hall, with glass windows and high ceilings. On the first floor, up to the grand staircase from the Entrance Hall, is the Great Hall, which seats up to 300 with a formal stage, and features the portraits of past Vice-Chancellors around the walls.

When the University of Manchester had a problem with a damp sub-basement at their historical Sackville Street building Timberwise were called upon to provide an expert solution to their damp problem. The sub-basement suffered from water running down the walls leading to puddles of water on the basement floor. Another problem with the basement was condensation as a result of steam from the steam room above – this then led to an issue with condensation on the staircase.

What a great opportunity to work in such a historic environment and student-driven establishment. Through our innovative waterproofing systems, we have made this basement a warm, dry place which the university can use for many functions ”

Timberwise Waterproofing Design Specialist


The Timberwise basement waterproofing solution involved the installation of a cavity drain membrane to the walls. The cavity drain membrane controls any moisture present on the walls and directs it into a perimeter drainage channel – in this instance a drainage channel around the perimeter of the basement and the steps. The perimeter drainage channel then leads into a sump pump unit which takes any water present away to a safe drain off point.

To give a fresh finish to the basement “WhiteWall” was fitted. ”WhiteWall” is a clean, protective finish that comes in 2m high sheets and is fixed onto the cavity drain membrane with a special adhesive.


The project took less than a week to complete and the end result was a dry, useable sub-basement area.  After completion of all the waterproofing works, Timberwise issued a certificate of guarantee providing the client with a 10-year insurance backed guarantee.
