Gutter Machines

ARP Ltd are the sole UK suppliers of the Ironman Aluminium Seamless Gutter Machine. The Ironman machine roll forms the gutter on site up to 30 metres in one run without any leaks. It carries a BBA accreditation in excess of 30 years and is the most modern and reliable machine available on the market.

Finlock Gutter Liner

In order to stop water penetrating through concrete finlock type gutters, it is necessary to provide a watertight and extremely durable lining to the water carrying Channel.

Finlock gutters were installed as standard on many large scale house building projects from 1945 onwards in an attempt to provide alternative to traditional wooden or iron guttering, both materials being in very short supply after the Second World War. It became apparent that water is penetrating in vast numbers of dwellings via the concrete "Finlock" gutters and causing serious structural defects.
