What are concrete gutters?

Concrete gutters are also referred to as Finlock gutters. They are gutters installed around the house to move rainwater and close the gaps at the top of the bricks. Concrete gutters are most found in homes that were built between the 1950s and 1970s.

Why were concrete gutters used?

Concrete gutters were used all over the UK; tens of thousands of homes still have them installed. They were used as a cost-effective approach to replacing the cast iron gutters in home building due to the steel shortage. Concrete gutters were believed to be a low maintenance approach to guttering in South Yorkshire and a large portion of the UK. Unfortunately, it has become apparent that concrete gutters are at best inefficient; at worst dangerous. Gutter repairs in South Yorkshire may not be the best solution for yourself and CGS has experts that will find the best solution for you.

How are they installed?

Concrete Finlock gutters are comprised of two troughs, lined up horizontal. One of the troughs is visible, and the other is against the wall to cover the cavity. They vary in length depending on application and range between 200mm and 250mm. They are usually reenforced with iron rods and sealed with bitumen. Bitumen is a viscous material used in road surfacing and roofing due to its waterproofing nature and corrosion resistance.


What are the different problems that can arise from concrete guttering in South Yorkshire?

The Elements

The weather, especially in the UK, can be somewhat unpredictable. One aspect of British weather is that it rains. Concrete is not watertight due to the air bubbles created during production. Rainwater will find ways into those air pockets over time and create larger cavities in the concrete guttering.


Water ingress

Between the concrete guttering and external walls, cold water will settle next to the wall and cause damp. Concrete Gutter Replacement in South Yorkshire will stop building damage if it is done as soon as possible. Damp will cultivate mould, which can grow and get into your lungs, which can be fatal.


Sunken Guttering

Guttering will shift and start to sink over time. Concrete is heavy and as the weathering takes effect, it will slip and at a minimum become ineffective. In extreme cases the concrete guttering can fall from the roof.

What are the advantages of replacing concrete gutters?

Concrete Gutter Replacement is essentially going to become a necessity the longer the concrete guttering is left unmaintained. Concrete Gutters in South Yorkshire need to be upgraded to a more efficient and damage resistant material. Depending on what you need, there is a solution for you. uPVC for example is a lightweight material that is watertight and much better with dealing with the weather. uPVC is also cheaper regarding gutter repairs. uPVC is also much more appealing to look at, concrete is notoriously a cold grey colour that detracts from the beauty of your home.
