Waterproofing Basements CPD Seminar (Refurbishment)

Seminar length: 45 to 60 minutes

Most existing basements in the UK date from the Victorian era and were never designed to provide habitable accomodation to the levels of dryness expected today. This seminar looks at the waterproofing options available when undertaking basement conversions / refurbishment, taking into account their suitability for various types of construction.

Note: This seminar has been fully updated to reflect the changes introduced in the latest revision of BS 8102 “Code of practice for protection of below ground structures against water from the ground”.

Topics covered include:

Refurbishment of Existing Basements

Refurbishment of existing basements

There are many reasons why an existing basement may need refurbishing. Some common reasons for refurbishing an existing basement include:

  • The original waterproofing has failed and must be repaired before the space can be utilised again
  • The basement requires an upgrade e.g. for additional storage space
  • Additional waterproof protection may be required, so an internal waterproofing system must be applied

Changing Uses of Cellars and Basements

Changing uses of cellars and basements

In some cases, a basement may need refurbishing due to a change in the desired use of the space. For example, the basement might be getting converted from a storage room into a more habitable space such as a kitchen or study. In these instances, the basement may require more than just waterproofing because the structure of the basement itself may require changes.

Types of Waterproofing System

Types of waterproofing system

The waterproofing systems available for a basement refurbishment are limited when compared to the options available for a newbuild basement. This is because the structure of the basement (brick, blockwork, concrete etc...) has already been chosen. According to BS 8102, only Type A (barrier protection) and Type C (drained protection) are suitable for existing basements.

Advantages and Disadvantages of Different Waterproofing Systems

Advantages and disadvantages of different waterproofing systems

Every basement waterproofing system has both advantages and disadvantages; for example, Type A systems should only be used with suitable substrates. This must be carefully considered before a final decision is made because an uninformed choice of waterproofing system could lead to an improper or failed installation, which can be very costly and time-consuming to fix.

Suitability for Given Situations

Choosing between Type A and Type C waterproofing systems can sometimes be difficult because both of them might be suitable. If this is the case, other factors should be considered such as the amount of space required and ease of repairability.

In general, Type A waterproofing systems will be much more difficult to repair than Type C systems. However, Type C systems will require regular maintenance to ensure that the system does not fail.
