Flat roof water proofing systems “calling a spade a spade”
Bitumen aka torch-on waterproofing
This is a black tar like substance from the petroleum industry. Its one of the oldest systems available.
Be careful there are different thickness available, starting from 2mm up to 8mm, some with one membrane (single core) and others two (Dule core)
This system needs to be replaced around 10 year cycle
This system is tricky to maintain or service, let me explain:
Bitumen gives off a gas continuously, that why it needs a sliver coating which is an aluminium dust to let the gas out. Should you use a Pva paint like your house walls, it will blow bubbles.
As this Gas escapes it the bitumen dehydrates and shrinks thus pulling loose from the roof surface and then starts to crease in the corners followed by splitting on the overlaps.
When melting a new piece of flexible bitumen to an old brittle piece the expansion and contraction of the suns heat each day results in them parting company.
This white geo-woven hardware store membrane saturated with a resin is as useful as the shop selling it and the person applying it. If you had the correct resin it would need replacing around the 3 – 5 year mark. Although its repairable, the constant top coat maintenance is this systems major down fall as there are no Acrylic resins which can hold water and be Uv stable! They either one or the other. Our Technology has not bridged this gap yet.
Cementious membrane waterproofing
Aka Life-proof system, this once off life time system is repairable and maintenance free. When used properly, it’s the strongest and most durable of all the systems. Coming in at the same price as bitumen, its a no-brainer.
The Cost savings long term make this the industrial choice.
