Inversion Drain Lining Using No Dig Technology


Posted on: December 30th, 2013

Repairing drain lining using No Dig Technology is a proven and established method of inserting a new replacement pipe within an existing damaged pipe without needing to excavate.

The new drain lining is inserted into the damaged pipe by a method called inversion which uses either water or air pressure to fit it tightly within the wall of the existing damaged pipe. When the inversion process is complete the new pipe structure is completely rigid, producing a stronger, reinforced pipe fitted within the existing pipe resulting in a minimal loss of diameter of approximately 6%.

The drain liner is manufactured from a special dense impermeable felt and is designed and tailored to fit exactly the internal dimension of the pipe to be refubished. The thickness of the lining material can be varied according to design specifications required. We recommend the following products:

Patch Repairs On Defective Pipes & Drains


Posted on: December 16th, 2013

When it comes to patch repairs on faulty pipes and drains we recommend the Renopatch kit from Renoline which comes packaged in a small disposable box and includes everything you require to carry out a successful pipe patch repair. The kit includes plastic protective packer sleeves, two pairs of latex gloves, a resin spreader, elastic bands and wire cable ties, fibre glass matting, ready to pour resin and a ground sheet.

Before starting the patch repair ensure that the pipe has been surveyed and is clear of any debris and obstructions. When ready to apply the Renopatch patch repair kit locate the defect with a CCTV drain camera and make a note the distance in order to carry out the patch repair. The next step is to feed the protective sleeve over the packer and secure both ends with the cable ties provided in the Renopatch kit and with a pair of snips cut flush the cable ties.

 

 

 

Spread the resin over the matting

Spread the resin over the matting

Using a sharp knife make a small hole in each end of the protective sleeve in order to allow air to escape when the packer is being inflated. Next, lay out the protective ground sheet and open up the fibre glass matting making sure the shiny side is facing upwards. Open up the resin containers and pour the thinner resin into the ticker resin container then replace the top securely and shake the container with the resin mixture vigorously for 30 seconds. The resin is now activated so pour the resin solution over the fibre glass matting and spread evenly using the spreader provided to the edges of the matting. (Due the the cross axle design of the matting in the Renopatch kit you only need to resin out the shiny side saving time and avoiding mess).

 

Roll the packer onto the matting

When the resin is spread simply fold each side into the middle of the matting, then take the packer and place in the middle of the matting, roll the packer onto the matting making sure the matting is centralised – the elastic bands or wire included in the kit can be used to secure the ends.

Slightly inflate the packer before inserting into the pipe, this will ensure any slackness is taken up, and connect the air hose into the packer and secure with the locking nut. Connect the rod to the packer and secure. Under the supervision of a drain camera insert the Renopatch into the pipe and push (or pull) the packer down to the pipe defect making sure that the patch is central and covering the defect.

 

 

 

 

Connect up the hoses to the compressor

Connect up the hoses to the compressor

Connect one end of the short air hose to the compressor and connect the other end of the short air hose to the regulator valve then connect the regulator to the long air hose which is already connected directly to the packer. Turn on the compressor and inflate to 2.5 bar. The regulator valve has a safety blow off release which means you can never over inflate the packer – on unstable pipework we would recommend inflating to a lower pressure.

 

 

 

Remove the packer

Remove the packer

Once the patch is cured simply twist the air release valve and deflate the packer and the packer should just slide out of the patch. Renoline supplies two different curing times for the Renopatch kit being half an hour and an hour and a half.

 

 

 

 

 

 

 

The following video shows step by step the process for applying a Renopatch patch repair.

 

We believe the Renopatch patch repair kit is the most user friendly pipe repair kit on the market and once you have tried it you will not want to use any other system. For more information and details of how to order please visit the Renoline website.

 

 



Why is a CCTV Drain Survey needed?


Posted on: December 16th, 2013

Drains, by their very nature of being underground, are subjected to a number of stresses over the years.  The ground can move dramatically, depending on how wet or dry it is, shrub or tree roots grow around the pipes and subsidence can also add high additional weight over the pipes. In order to check drains and pipes periodically a CCTV Drain Survey can be carried out.

Traditional Salt Glazed sewer pipes will start to breakdown after a while and these stresses can start to cause leaking at the joints, cracking along the pipes or at worst complete collapse. Leaky soil pipes are not only a potential health hazard but can also wash away the foundations of a property causing subsidence. Damaged pipes can cause blockages.

When buying a property, the mortgage lender will often want assurance that the pipes are in good order. How can this be done, without having to expose the pipes? A Close Circuit Television (CCTV) drain survey is ideal for this purpose. This is a totally non-invasive process in which we insert a ‘rod’ with a camera attached at one end, connected to a monitor and recording system at the other end. If a problem is detected, an on-screen meter counter can determine the exact position.

 

If a drain repair or patch to the pipe is necessary, there are a number of options available, including replacing the broken section by excavation, or alternatively and in most cases preferable by no-dig or trenchless technology which involves relining the drain or pipe from within with a Glass reinforced plastic. This is particularly useful where pipes are inaccessible, such as under buildings.

After a drain repair has been carried out a further CCTV drain survey will need to be carried out check to make sure that water is free flowing without any restrictions.

Drain Camera Repairs


Posted on: December 12th, 2013

Many customers ask if we can repair competitors’ cameras, in theory all cameras are similar, they may vary in voltages and design, but there isn’t a lot of difference overall.  Over the years here at Scanprobe, we have repaired numerous competitors’ cameras and our repair team always strive to complete repairs to the highest possible standards.

 

When it comes to drain camera repairs, you tend to find that the more expensive the pipe inspection system is to purchase, the more complicated it is repair, customers should be aware of this when deciding which drain camera to purchase. Bear in mind that a drain camera is a tool, like a drill and they can fail, but unlike a drill a drain camera is a sensitive piece of electronic equipment, so care should be taken when using your camera system. Unlike most of our competitors, Scanprobe offer a same day drain camera repair service, and should we be unable to complete your repair in one day, we do offer loan units to use until your drain camera system has been repaired (subject to availability). You should also keep in mind that all drain cameras contain parts that through normal wear and tear will need repair/replacing after time such as the pushrod and nylon rollers. Scanprobe recommend that to prolong the life of your camera you should drop it into our workshop for a general service.

 

If you have purchased a competitors’ camera and need to have it repaired by Scanprobe we advise bringing it in and having one of our repair technicians assess the system to see if we can successfully carry out repairs. In the past we have repaired numerous competitors’ drain cameras, but are sometimes limited in what we can repair due to not carrying parts for other systems, although we will attempt to modify our own parts to fit other systems where possible. We have found 8/10 times we have successfully repaired other units. So yes, we can repair competitors’ drain cameras but depending on what parts we carry.

 

One of our team will be happy to advise you on any drain camera repairs needed.

Getting A Drain Survey – What Is Involved?


Posted on: December 11th, 2013

DRAINS! We don’t tend to think of them. It’s the place where your waste goes and we don’t want to know about that, as long as it gets where it’s got to go. The thing is (when there is a problem), like anything, the earlier you spot it the better. Since I started Hire at Scanprobe I always get asked the same question:-  I need to survey my drains, which drain camera would you recommend? And I always ask, is it for insurance purposes? The reason I ask this question is to do with the quality of drain survey you require. If you just wanted to check to see if there’s something obstructing the water flow, you can simply use our look-see supercam. This camera is a basic unit you can just pop down the pipe to quickly identify any major issues. Whereas for insurance purposes or for the sale/purchase of a house you will require more information.

 

The reason it’s a good idea to have a drain survey done is probably obvious, but it can tell you much more about the property than most realize. It can discover hidden man holes, which in some cases are inside the property especially if it’s had an extension. ItScanprobe Series 6 Drain Camera tells you where each pipe goes, what they are for and whether you will come across them if you’re fitting in foundations for a new extension. By looking for offset joints or cracks a drain survey can tell you if there’s been any subsidence to the property over the years and whether it’s still occurring. You can check for root ingress from nearby trees. Whether your pipes are running through to the neighbor or to the main sewer or even a cesspit. These are things I would definitely want to know before I purchased a property. Now using a look-see unit will tell you most of these things but the Scanprobe Series 6 is the unit 90% of people would use. The reason for this is down to the quality of the system. For instance:- the drain camera on the Scanprobe Series 6 is self levelling, which means the camera stays the right way up in the pipe giving you a much easier time determining where each branch enters. Also by knowing which is top and bottom you can determine whether an obstruction will effect the flow, as sometimes when the pipes are fitted, some of the adhesive can seep into the pipe causing obstruction, but if this is on the top of the pipe and not too big you could (in theory) leave it as it won’t effect the flow.

 

To survey pipes larger then 150mm I would recommend getting a company in to do it. Mainly because the cameras required, are a lot more complicated (our company can assist you on this). But for a domestic property, I don’t see why any competent person couldn’t hire our equipment and do it themselves.

What To Look For In A Quality Drain Lining Resin


Posted on: December 10th, 2013

When looking for a quality drain lining resin it is important to look for a resin that is 100% pure polyester. Pure polyester resin is formulated for maximum ease of use and performance, rather than for low cost. In the case of Renoline drain lining resin Norsodyne E8786, the formula also contains a number of additives including a yellow dye which makes it easier for the user to see and eliminates any air bubbles which may become trapped in the fleece during the wet out phase. Other additives help prevent slumping in the pipe and stabilise the cure during long periods of storage.

 

Lower quality filled drain lining resins have totally different characteristics to 100% pure polyester resin and they are cheaper to produce as part of the resin has been replaced with chalk filler giving it a distinctive chalky colour. These lower grade drain lining resins are heavier meaning less resin in every can and they can be stiffer and more brittle meaning that the resin has a tendency to slump down to the bottom of the pipe leaving a thin crown and thicker bottom to the liner which make them unsuitable for the lining of drains. The filler also has a tendency to leave millions of minute air bubbles in the resin possibly creating a porous liner once cured – the filler also makes for a harder impregnation when wetting out into felt drain liner. (If you weigh a litre of pure resin against a litre of filled resin the filled resin would be approximately 30% heavier)

 

Renoline in partnership with Cray Valley provides 100% pure polyester drain lining resins based on tried and tested technologies where maximum performance in the field has always been the overriding priority rather than opt for lower cost, inferior quality products.
