Liquid waterproofing systems (LWS) are chemical compounds that can be applied to surfaces in liquid form and which quickly ‘cure’ or dry to form a solid waterproof membrane.
Bitumen was the first form of liquid waterproofing and has been used for the purpose for thousands of years. In the last two decades, technological improvements in liquid products have substantially increased performance and durability. They now account for an increasing part of the waterproofing market.
Liquid waterproofing systems offer a wide range of options:
|
n |
They can be applied by brush, spray or roller. |
|
n |
Most are one component but some are two component systems. |
|
n |
Some can be installed cold, others require heating. |
|
n |
They are based on natural bitumen, artificial polyester, polyurethane, epoxy or Methyl Methacrylate (MMA) resins. |
Liquid systems are high performance waterproofing solutions, as they are:
|
n |
Seamless membranes : no vulnerable joints to allow water ingress. |
|
n |
Fully bonded to the substrate : the membrane adheres fully to the substrate and becomes integral part of the substrate. |
|
n |
Compatible with most substrates : can negate the requirement for removing existing coverings easily detailed |
|
n |
Easily detailed : complex shapes can be securely waterproofed. |
Liquid waterproofing systems offer many additionnal benefits :
|
n |
Long life : correctly installed and maintained, LWS can provide a long-term lifespan, often in excess of 25 years. |
|
n |
Speed of installation : minimum disruption to the client. |
|
n |
Cost effectiveness : liquid systems can provide
substantial savings compared with sheet systems. |
|
n |
Versatility : LWS have been developed for use on flat, pitched even domed roofs. Their adaptability even extends to other uses such as the waterproofing of balconies, walkways, car parks, bridges and
structural applications. |
|
n |
Wide range of specifications : differing properties and thicknesses of materials suit different applications and provide a variety of lifespans according to
requirements |
