Whether dealing with blocked drains, maintaining sewage treatment plants, carrying out drain re-lining, performing pitched fibre repairs, installing soakaways or utilising CCTV drain surveys to diagnose other such issues, we are here to provide efficient, reliable solutions. Below, we’ve outlined some common drainage concerns and how our experienced team can help.

Blocked Drains: Causes and Solutions
Blocked drains are among the most frequent issues faced by domestic and commercial clients around Portsmouth. Common causes include:
- Build-up of grease, fat and oil
- Intrusion of tree roots
- Accumulation of foreign objects
- Structural pipe defects
Our engineers use advanced techniques, such as high-pressure jetting and CCTV surveys, to quickly locate and resolve blockages. This ensures minimal disruption and a long-term fix.
When to Consider Sewage Treatment Plants
Sewage treatment plants are essential for properties not connected to the mains sewer. Common concerns we can address as your trusted local drainage contractor include:
- Overflows due to improper maintenance
- Odours caused by system malfunctions
- Inefficient performance due to age or wear
Our team offers comprehensive services, including installation, repair and maintenance of sewage treatment plants in Portsmouth. We’ll ensure your system operates efficiently and complies with local environmental regulations.

The Importance of CCTV Surveys
CCTV surveys provide a non-invasive method to inspect your drainage system. They help identify:
- Cracks or structural damage
- Blockages and debris build-up
- Issues requiring drain re-lining or repairs
Smart Drainz uses high-resolution cameras to diagnose problems accurately, reducing the need for disruptive excavation.
Effective Drain Re-Lining
Drain re-lining is an innovative solution for damaged pipes. Signs you may require a drainage contractor to carry out this service include:
- Recurring blockages
- Leaks or damp patches
- Structural deterioration
Our method involves inserting a resin-coated liner into the pipe, creating a durable, watertight seal once cured. This process is cost-effective and minimises disruption.
Addressing Surface Water with Soakaways
Soakaways help manage excess surface water, reducing the risk of flooding. Common issues include:
- Poor drainage in driveways or gardens
- Water pooling after heavy rain
- Compliance with local drainage regulations
As Portsmouth’s favoured local drainage contractor, Smart Drainz designs and installs soakaways tailored to your property’s needs, ensuring long-term performance and reliability.
Pitched Fibre Repairs for Longevity
Pitched fibre repairs address problems in ageing pipes, such as blistering, deformation or collapse. Our repair methods include re-rounding and patching to restore the pipe’s structural integrity. This ensures continued functionality without the need for full replacement.
