In many older buildings, the original pipes are made of galvanised iron or lead, materials that over time corrode and reduce in diameter. This leads to the build-up of sediment and blockages. In this comprehensive guide we will explore the common causes of these clogs and, more importantly, what preventative methods you can use to avoid complicated and costly repairs without renovating or trampling your pavement.
What causes frequent traffic jams in old buildings?
Internal corrosion of pipelines
Rust deposits adhere to the inside of metal pipes, reducing their capacity and slowing down the flow. Over time, the irregular flow encourages the accumulation of solid debris.
Accumulation of limescale and domestic waste
In areas with hard water, such as the Marina Alta, limescale mixes with grease and organic debris, creating crusts that clog drains. This is often manifested by slow drains and persistent odours.
Seepage and encroaching roots
Cracks or deteriorated joints allow tree roots or soil to get inside the pipe. For more information, see our guide to root infiltration in pipes.
Inappropriate use and outdated facilities
Throwing away greasy debris, wipes or other residues that do not dissolve accelerates clogging. To learn reliable home methods, check out how to clean pipes without aggressive products.
Effective strategies to prevent traffic jams without road works
Visual and camera inspection
Regular inspection of the internal network, especially at critical points such as elbows or downpipes, allows wear and tear to be detected before it becomes a blockage. Camera inspection provides an accurate diagnosis without the need for building work.
Professional preventive cleaning
The use of high pressure washers in drains removes compacted sediment, roots or stubborn grease. In addition, we offer specialised pipe cleaning to maintain optimum flow.
Trenchless internal rehabilitation (relining)
When there are cracks or loss of diameter, relining renews the system without the need for building work. If you want to know more, see our repair option without building work.
Spot repair of joints and splices
Leaks or seepage often originate from damaged joints. Repairing them or replacing affected segments prevents major problems and protects the overall installation.
