Concrete gutters were built on the side of homes and were typically found on homes built between 1950s-1970s
What Are Concrete Gutters? Why Were They Used?
Concrete gutters were used all over the UK; tens of thousands of homes still have them installed. They were used as a cheaper alternative to stell and replaced the cast iron gutters in home building due to the steel and other metal shortages during the war effort. The concrete gutters were seen as a low cost and resilient alternative. Furthermore, concrete guttering was a low maintenance approach to guttering in a large portion of the UK.
How are they installed?
Concrete gutters are typically comprised of two troughs that are lined up horizontal. One of the troughs is visible, and the other is above the wall covering the cavity. The troughs differ in length and range between 200mm and 250mm. They are occasionally reinforced with iron rods and sealed with bitumen, but this is down to the owner’s personal preference. Bitumen is a viscous material used in road surfacing and roofing due to its waterproof properties and corrosion resistance and therefore can be beneficial to install.
The problems with Concrete Guttering
Despite their initial positives, there are a few issues that have become apparent with concrete gutters. Unfortunately, concrete gutters have not stood the test of time and are prone to several issues, such as leaking and mould. As well as in some cases proving to be unsafe. Additionally, they can be quite costly to repair and replace in the short and long term. However, concrete guttering is less common than the uPVC alternative and is often encouraged to be changed and replaced entirely with a total gutter replacement.
