Up and Under specialise in Basement / Cellar Conversions and Basement / Cellar waterproofing in the Manchester areas…


Many properties are built over an unreleased asset, a basement. Over the years, there has been an ever increasing demand for usable space within buildings, both for domestic and commercial purposes.

Conversion of basements has become a logical solution to this demand. However, to achieve dry usable rooms, a critical issue is the need to install effective and long lasting waterproofing systems. The rising water table across the country has led to more and more, once reasonably dry basements, becoming subject to dampness and in some cases flooding.

Architects, Builders, Surveyors and the general public have all been found scratching their heads as to how to combat these problems, in both existing basements and new constructions….


UP & UNDER provide a full survey, design and installation service for basement waterproofing. Having completed our survey and identifying the problem, we then question the client as to the end usage of the conversion. Only after doing both can the correct and most value for money waterproofing system be installed.

Our preferred option is cavity drainage membranes, with drainage channels to a sump and pump. These membranes combine excellent water control and damp proofing, combined with cleanliness and a quicker installation.

However, in some instances, i.e. where an area is to be used for storage only, other options are available which may be more cost effective.

UP & UNDER have been successfully working on basements for 25 years, and to date have had no failures. This in itself is proof of our expertise in our field, as we do not believe many of our competitors hold this record.
