STRUCTURAL ELEMENTS Cool ideas for waterproofing
Victoria Ramwell of Kemper System offers specification advice on the versatile cold-applied liquid waterproofing method for residential properties
key theme throughout the roofing sector and the construction industry as a whole as we enter a new year is the push towards some form of normality. The Government’s plans unveiled in 2020 to “build back better” are keenly focused on housing, particularly new build projects, and this is where liquid waterproofing really comes into its own. Its versatility means that liquid waterproofing can be specified and installed onto a range of substrates used in the housing sector, and tackle many different project challenges, including new-build developments.

Liquid specification The development of any residential scheme requires adequate planning to ensure budget and time constraints are adhered to – not to mention the safety implications and potential disruption for any nearby residents. Many, if not all liquid solutions can be applied not only to a roofing area, but also balconies and walkways. It can also be used within a built-up roof system such as a green or blue roof, and offer easy application around areas which have lots of outlets, such as air conditioning and ventilation units or plants.
This versatility is why liquids are one of the fastest growing solutions in the flat roofing sector. Within a housing setting, this characteristic is key, as there can be a number of complex application areas which cold-applied liquids can tackle with ease as they are roller and /or brush applied with minimal equipment needed on site. If specifying a liquid system, take the time to research which is most suitable for your project. Consider requirements such as compliance with Building Regulations, for example fire resistance, or specific performance characteristics – including the compatibility of the surfaces to be waterproofed, ability to withstand substrate movement, and resistance to damage from anticipated load levels or trafficking.

Independent product accreditation is used to effectively communicate conformity and suitability, so it is advisable to research the manufacturer’s current product certification. An example is BBA certification, but there are others.
Beware of specification switching As we know, specification switching can sometimes happen during housing projects because of budget or time constraints. Maintaining the specification on a project is often difficult, yet the implications of not
