What Is A Concrete Gutter?

Finlock Guttering, also referred to as concrete guttering, is a form of guttering made of concrete. Concrete gutters are typically found in properties that were built between the 1950s and 1970s. Such gutters were initially introduced as a replacement for cast iron guttering systems, as there was a shortage of steel materials at the time. Concrete was the logical replacement, as it is both a durable and low-cost alternative to steel. Finlock gutters additionally provided a solution for closing the top of ‘cavity’ walls, which were also being introduced at the time – furthering their popularity.

Finlock concrete gutters are made of two horizontal troughs, which sit at the top of cavity walls. One trough is visible and serves as the gutter. The other trough spans the cavity between your internal and external walls. Finlock gutters vary in length between 200mm and 250mm. Although predominantly concrete, Finlock blocks were oftentimes connected using steel-reinforced rods and mortar. The joints between the blocks were then sealed and lined with a waterproof coating – such as bitumen or mineral felt.

Finlock guttering has since ceased in production, due to the eroding nature of the concrete’s material composition, incurring detrimental problems for users if required for long-term usage. In light of this, this blog examines what these problems are specifically, how much they will cost users if unresolved, as well as the best way to rectify them, and the benefits you may experience as a result.

What Is The Process Of Replacement?

Replacing Finlock guttering is the best way of eradicating their associated problems. Be sure to have the work completed by a professional, as some concrete guttering is extremely heavy, and may contain asbestos – therefore, consulting an experienced tradesman confirms that the job will be completed safely and effectively.

The process for gutter replacement is as follows:


  1. Our crew will deliver and erect our Easi-dec access equipment, which limits the need for highly visible scaffolding, saving you money and hassle. We can build our Easi-dec scaffolds on arrival and remove them the same day.
  2. We begin the process by pushing back the first row of tiles, removing any failed aluminium lining, and any pre-existing face plates.
  3. We then employ a diamond-tipped cutting blade, to remove the Finlock concrete blocks. This can be a noisy and dusty process, which needs to be done properly to avoid any potential structural damage to the property.
  4. We then install a pressure-treated timber faceplate to the remaining concrete – giving us a straight and solid base to attach the uPVC products to, eliminating cold bridging.
  5. We then install a uPVC fascia, soffit, and guttering to your property, ensuring that we use only the best materials, that have a 50-year manufacturer’s guarantee against fault, fading, or discolouration.
  6. We then install an E.P.S tray to your property; sliding it underneath the felt and making sure it overruns into the new guttering. An E.P.S tray helps to provide ventilation to your roof space, stopping water from getting through any tears or holes along the bottom of your felt, and directing it into the new guttering.
  7. The penultimate stage of the Finlock gutter replacement process is to join your new uPVC guttering solution to next door’s concrete guttering (if you share a downpipe). Our employees have a tried and tested method, as well as an abundance of skills to do this.
  8. Finally, we make sure to clean up any mess, putting all your rubbish into a heavy-duty ‘hippo’ waste bag to be collected.
