London is one of the most sort after capitals of the world to live. London is made up of an array of different properties, both residential and commercial, which are either Victorian or Edwardian. Many of the larger properties were built with basements for staff accommodation, but over the years they not been needed and have fallen into disrepair.
Many London basements and cellars that Tapco HomeDry have surveyed since 1971 are heavily affected by damp and timber decay, which has caused even more deterioration and damage, making the rooms uninhabitable.
In some cases the damp, insufficient temperature and lack of ventilation has been ideal conditions for the dreaded dry rot (Serpula lachrymans) to thrive and cause even more devastation.

Damp proofing your Basement to create a favourite room

Because of the massive increase in London property prices over the years, domestic and commercial properties in areas are at a premium and many owners need more space but don’t want to move. If this is the case with you, without doubt converting your wasted basement or cellar is the most economical and profitable way of creating your favourite rooms.
Whatever you intend to use your new room or rooms for the most important aspect of the whole job is damp proofing to ensure that the walls and floors are dry and stay that way for a long time. It is also very important that all aspects of the damp proofing are only carried out by an experienced damp roofing specialist such as Tapco HomeDry and not by a general builder. The main two methods of basement and cellar damp proofing that Tapco use are:

This is carried out by installing a high density studded membrane to the walls and floors, using special waterproof fixings, installing drainage channels and a sump chamber and pump. Once the system is fully installed it can either be dry lined or plastered over ready for your contractors or us to complete.
