Dry basement for St Matthew's Church
in central Manchester

The offices of SJM, a leading gigs and tours specialist, take up the entire building of St Matthews church and although they were using the basement previously, it was suffering from damp and slight levels of water ingress and they needed to make the basement dry all the time.


The solution involved stripping out the fixtures and fittings, cupboards, non structural walls or sole plates, digging and installing WaterGuard channel around the perimeter of the basement, digging and installing the TripleSafe Sump Pump, which includes three pumps, together with lining of all walls, steps and floors with cavity drain membrane, finished by linking this all into the WaterGuard Channel.


Owing to the scale and resources required to carry out the waterproofing and associated works, and as main contractors and project managers of the whole project, the contractor was required to conform with the Health and Safety Executive, issue an F10 and follow Construction (Design and Management) Regulations.


The TripleSafe Pump has revolutionised the contractor’s basement waterproofing business and as the name implies, it contains three pumps in one clever chamber. It is capable of pumping vast quantities of water at all times and should the power fail, the third pump is a battery back up pump powered by a specialist high powered, high longevity battery. The pump is automatically specified into a system where the customer requires their basement to be dry all the time.
On completion of the specialist water management works, the contractor re-instated cupboards, laid a chipboard floor, reinstated shelves, plumbing, electrical supplies and computer networking, as well as plasterboard and skim to all walls. Due to the joinery skills on site the client also requested the creation of further windows to the internal walls allowing greater light to the other areas of the basement.

The client now has a dry basement.
