Bituminous products are perfect for the waterproofing of roofs on buildings as they move with the structure as they are not too rigid and do not absorb water. Waterproofing membranes systems are designed to protect both residential and commercial buildings through a mixed substance made up of organic liquids that are highly sticky and viscous. Bitumen is a hydrocarbon and is created naturally from crude oil, it is a useful carbon store and does not generate greenhouse gases.
The membrane rolls off the base product being fed through a bitumen saturation tank.
Large rollers used to feed the membrane through the manufacturing process, impregnating the membrane.
Bitumen sheeting being applied to a flat roof area.
The last of the membrane being measured for a perfect fit.
Perfect for waterproofing
Bitumen is a hydrocarbon and is created naturally from crude oil. It is a useful carbon store and does not generate greenhouse gases. The membranes are therefore a sustainable way of storing carbon on the Earth’s surface
Bituminous membranes are made up of more than one product.
There are many other advantages of using bitumen waterproofing products:
As well as protecting buildings, bituminous roofing products can be in harmony with their environmental surroundings as different mineral finishes can be applied to the top surfaces.
The products have an extremely long life span, with most membranes having BS (British Standards) marks against each product name.
The fumes given off during installation are not harmful to human health and there is low noise pollution during application.
Bituminous membranes protect insulation and can reflect harmful sun rays. New products also contain photovoltaic cells that can produce solar energy.
