The Twelve Days of Christmas With Hydro Cleansing | 4. Trenchless Tech

“On the fourth day of Christmas,
my true love sent to me,
four broken pipes,
three Septic Tanks,
two feet of tree roots,
and Hydro Cleansing’s Mega-Heat…”

Day four of the Christmas countdown is upon us, and so is the latest blog instalment! Today’s blog is all about our talented CCTV team and their top of the range trenchless technology. Drain repair equipment has come a long way in the past few years. Discovering you have a cracked or damaged  pipe no longer means digging up your garden and weeks of work. Advances in technology mean that repairs can begin almost immediately with no digging or disruption. Read on for a journey of drain lining discovery!

How does it work?

When you request a drain relining service the first step is to identify the cause of damage. We will send a CCTV unit into the pipe to assess the damage and check if a drain pipe relining is feasible. When we have completed this stage and agreed a drain relining is the best option, our team will start work!

What does it involve?

We will use one of our state of the art jet vac tankers to clean and remove any blockages within the drain or sewer pipe. This is to ensure the pipe has a good clean surface for the resin to bond to. We then insert a deflated packer (also known as a bladder) within the drain, pushing it through to the damaged area.  Once we have confirmed we are covering the damaged part of the drain with the drain relining patch, the packer (bladder) will then be inflated.

This will force the drain relining to bond with and secure itself to the inside of the drain or sewer pipe. Once dried, this makes a completely secure, leak-proof seal. Once we have removed the packer our team will then re-insert the CCTV unit into the newly repaired pipe to make sure that the resin has cured and there are no leaks. Drain relining can patch drain pipes from as little as 100mm diameter up to 1.5 metres and is a permanent solution.

The Twelve Days of Christmas With Hydro Cleansing | 2. Case Study NPL

“On the second day of Christmas,
my true love sent to me,
two feet of tree roots,
and Hydro Cleansing’s Mega-Heat…”

Continuing our twelve day countdown to Christmas, today’s blog is a nice juicy case study! However, this isn’t just any case study, this case study features blocked culverts, four foot long tree roots, over 50 TONNES of silt, and of course, an expert team of Hydro Cleansing engineers getting the job done. 

Back in the Summer we were called out to deal with some blocked culverts, syphons and silt traps by the NPL. On our arrival it was clear that there was something seriously big blocking the syphon under the railway, even our camera couldn’t travel underneath to get a clear picture. Upon further investigation the engineers discovered that the blockage was clusters of tree roots growing through the tunnels. Check out the full scope of works below!

Client – National Physical Laboratories | Kings River Outfall Desilting

Scope of Works – Desilting of culvert | Root cutting in syphon under railway | Desilting of silt traps

  1. The culvert in Normansfield Road had a high level of silt and elevated water level, the camera was then unable to return a picture of the internal condition of the pipe. We needed to remove this silt and reduce the flow during the survey, we then proposed to undertake this with a super combination unit taking one day to complete and resurvey.
  1. The syphon under the rail way had root ingress which prevented the passage of the camera, to remove this we needed to reduce the flow through the culvert and use high pressure root cutting with specialist root cutting nozzles suitable for large bore pipes. We took one day to complete and resurvey.
  1. The silt traps in five manholes needed de-silting, they contained an average of 1m of silt each. The silt traps are 2.5m in diameter which will yield approximately nine tonnes each. We took two days to complete.

The Twelve Days of Christmas With Hydro Cleansing | 1. Mega-Heat

“On the first day of Christmas,
my true love sent to me,
Hydro Cleansing’s Mega-Heat…”

The twelve day countdown to Christmas has officially begun, so to celebrate and boost our festive cheer, we will be posting on the blog EVERY DAY UNTIL CHRISTMAS! Each one of our posts will be specifically  focused around one of our services, starting with our very own Mega-Heat! So sit back, relax, and let the Hydro Cleansing Christmas content fest begin!

Put simply, Mega-Heat is a high pressure, high temperature  jetting service… however, if you dig a little deeper, you’ll see that it is so much more! It can reach temperatures of up to 105°C and jet at up to 3000psi. Worried about chemicals or damaging surfaces? Not with Mega-Heat! The power and heat that this impressive bit of kit combines make tackling oil spills, graffiti or dirty guttering fast and hassle free for our expert engineers, without having to use any abrasive or chemical products.

Mega-Heat is one of our key fleet members that we use to tackle a variety of problems around London and the South East. From blasting off chewing gum on the busy streets of our capital, to making industrial machinery sparkle, we offer unrivalled efficiency and manoeuvrability. This is in part thanks to our unique van mounting; usually a unit with these capabilities would be carried on the back of a trailer, or by a team. By custom mounting ours into the van, we are able to access and start work immediately. This cuts down response time, the number of vehicles needed and ultimately the time needed to complete the job.

Some of the jobs that Mega-Heat can be used for are:

Graffiti Removal
– Concrete Cleaning –
– Gutter Cleaning –
– Stone & Building Cleaning –
Oil, Fat & Grease Removal
– Floor Cleaning –
– Chewing Gum Removal –
– Paint Removal –

Check out what we achieved in Limehouse in two hours with one engineer using Mega-Heat…
