When Are Drain Excavation Services Needed

How to Confirm If Excavation Is Necessary

You can assess whether or not drain excavation is needed by inspecting the scale of the drainage issue. We recommend looking out for common signs like foul odours, persistent blockages, slow-draining water, or flooding in your property. While minor problems can be resolved with much less disruptive or invasive methods such as jetting or rodding, if you discover any structural damage to your pipes, for example, collapses, cracks, or severe root intrusion, you may need excavation. 

Professional drainage surveys use CCTV cameras and hi-tech quality, this is the most reliable way to confirm if your drains need to be excavated. These devices allow engineers to inspect the pipes' interior, pinpoint the exact location of the issue, and make decision if excavation is solution. Excavation is often the last resort for many drainage professionals because of how disruptive it can be to the ground and surrounding environment; however, when it is necessary, it is unavoidable. We encourage all home and property owners to consult a trusted specialist for an accurate survey to make sure before going ahead with an excavation. 

Subsidence or Structural Damage Around Drains

When your pipes collapse or begin to leak, this may be due to structural damage or subsidence around your drains. Drains that are damaged can allow water to escape and erode away the strength of the surrounding soil, meaning there is a lack of stability for the pipework. Once this occurs, the area around the drain can crack or even sink, and this can negatively affect the walls, paving, or foundations of your property.  

One of the biggest signs of subsidence include cracks in buildings, uneven surfaces, or gaps in structures and the ground. When drains and structure of your home are neglected, the issues at hand can only worsen, leading to costly repairs. With the help of a professional drainage survey, you'll be able to identify the severity of the damages and find an appropriate solution, and this can involve relining, pipe repairs, or excavation. 

Severe Blockages That Cannot Be Cleared

In some circumstances, there are more severe blockages that cannot be completely cleared using more common plumbing methods like rodding, plunging, or jetting, and this suggests a much deeper problem inside the drainage system. These blockages are often a product of debris, grease, or foreign objects, or it could be an example of something more difficult to tackle like root intrusion, structural damage, or collapsed pipes. 

Blockages usually often cause foul odours, slow drainage, or repeated flooding, and these challenging symptoms must be addressed as quickly as possible. A local, quality drainage company can perform a CCTV survey that will help you locate and diagnose your blockage precisely. The findings of the assessment will determine what solutions are carried out, and this can involve repairs or clearing techniques that will restore the drains function. 

Replacing Old or Corroded Drain Pipes

Old or corroded drain pipes usually need to be replaced when they have sustained too much wear and tear or have reached the end of their lifespan. Over time, pipes made from materials like galvanised steel, clay, or cast iron can eventually deteriorate, resulting in cracks, leaks, or blockages. Corrosion can weaken the pipes walls and this means they allow tree roots to penetrate or they can collapse. 

Visible damage, water pooling, and recurring drainage problems are a huge indication that you may need a replacement. Modern materials like HDPE or PVC provide homeowners with a much more long-lasting or durable solution, improving the performance and reducing the need for costly maintenance. If you're unsure whether or not your pipes need replacing, we recommend calling local professionals for an inspection, and this will help to confirm if it's the best option for you. 

Building Extensions or Renovations Impacting Drains

It's always good to be aware that any major building renovations or extensions can largely impact your existing drains, and this is likely due to the changes made to the property's layout may involve changes to the drainage system. Construction work can often block access to inspection chambers, disrupt pipe locations, or add additional loads to the system. 

Before you begin any construction project, the best thing to do is assess how the existing plans you have for your new property or dream home will impact the plumbing systems. Every part of your design layout must comply with local building regulations. 

A complete survey can help to identify the current layout of your drainage system, helping to plan any upgrades, necessary diversions, or reinstallations. Ignoring this part of your planning process can lead to flooding, structural damage, or drainage issues once the work is done. Contacting a drainage professional can help make sure your system adapts well to support the new construction work.
