The Dark Side of Pitch Fibre Drainage: Exploring the Negatives


Introduction: In the realm of drainage solutions, pitch fibre drainage once stood out as a cost-effective and flexible option. However, as time has passed and technology has advanced, the negatives of pitch fibre drainage have become increasingly apparent. In this blog post, we delve into the darker aspects of pitch fibre drainage, shedding light on the disadvantages that may influence your decision-making process when it comes to drainage solutions.

  1. Limited Lifespan: One of the most significant drawbacks of pitch fibre drainage is its limited lifespan. Unlike more durable materials such as PVC or HDPE, pitch fibre pipes degrade relatively quickly over time. The coal tar pitch coating, which initially provides corrosion resistance, deteriorates, leading to structural issues and reduced performance. This limited lifespan means that pitch fibre drainage systems may require frequent repairs or replacements, adding to long-term maintenance costs.
  2. Susceptibility to Deformation: Pitch fibre pipes are prone to deformation under various conditions. Heavy loads or ground movement can cause the pipes to flatten or distort, restricting flow and increasing the risk of blockages. This susceptibility to deformation undermines the effectiveness of pitch fibre drainage systems, particularly in areas prone to seismic activity or heavy traffic.
  3. Environmental Concerns: The use of coal tar pitch in pitch fibre drainage systems raises significant environmental concerns. Coal tar is a byproduct of the coal distillation process and contains various hazardous substances, including polycyclic aromatic hydrocarbons (PAHs). These compounds are known to be carcinogenic and can leach into the surrounding soil and water, posing risks to human health and the environment. Disposal of old pitch fibre pipes requires careful handling to prevent contamination, adding to the environmental impact of this drainage solution.

Conclusion: While pitch fibre drainage once offered a viable solution for drainage needs, its negatives have become increasingly apparent in recent years. From limited lifespan and susceptibility to deformation to environmental concerns and limited availability, there are several factors to consider before opting for pitch fibre drainage systems. As technology continues to evolve, exploring alternative materials with improved durability and sustainability may offer better long-term solutions for drainage challenges.

High pressure water jetting

High Pressure Water Jetting!

High pressure water jetting to some people can seem daunting. But here at Drainage Plus its something we carry out every single day.

So what is High-Pressure Water Jetting some people may ask?

Well, High-Pressure Water Jetting is where a large amount of water is pumped through a hose up to 3000psi. This high pressure when put through your drainage system can descale, clean and unblock your drainage.

Previously, no more than 10 years ago, drain rods were used to clear blockages. When using drain rods a number of problems can occur such as compacting the blockage, pushing the drainage blockage further down the pipe, and in some cases getting the drain rods stuck which can result in having to excavate to get the drain rods back.

With High Pressure Water Jetting it is a fast & effective way to clean and unblock drainage systems. Should your drain have fat buildup then the 3000psi high pressure water jetting system can clear through, break up and wash away the years of buildup within minutes.

High pressure water jetting restores your dirty drainage system back to its original condition and can have it looking brand new.

We recommend high pressure water jetting to descale pipework, unblock blocked drains & fat removal.

With our unique system, we can even cut out tree roots!

Very often tree roots gain access into the drainage system from nearby trees & bushes. These roots can cause issues because they slow down any waste resulting in blockages. In some cases, the roots can be so severe that they block the system up completely.

We can use High Pressure Water Jetting to remove tree roots and open up your drainage system to ensure full flow is achieved.

Should you ever have any drainage issues then contact one of our experts and we can recommend the correct method to get your drainage system back up and running!
