More about Sika Liquid Plastics and waterproof membranes

There are various liquid coatings and waterproof membrane systems out in the market today. Colin has been using these types of systems for over 15 years. One product supplied by Sika Liquid Plastics is known as Decothane. This type of product amongst others is fantastically versatile and can be used for virtually any type of waterproofing. Colin has used this and other Sika Liquid Plastics products to coat chimneys, walls, floors and even boats! If you have a problem area which needs to be made water-tight, Colin will be able to advise on a suitable system. There are budget systems out there too if you need an urgent problem addressed until such time that your finances are able to cope with a long term solution. The Sika 618 and 625 systems are the most popular amongst our clients. These systems are also incredibly flexible and malleable enabling the hardest areas to be coated and waterproofed.
