Drainage problems can cause embarrassment and have a detrimental effect on trade should it get out of control.

The effect of bad drainage can result in loss of trade due to health and safety issues, foul smell and loss of welfare facilities. It can also leave your company with a bad reputation if customers are ever exposed to raw sewage.

At dpgplus we have a discreet and professional practice for dealing with all your drainage needs and with minimal disruption to your customers.

We are SEPA approved giving us a licence to carry and dispose of controlled waste and we can undertake work throughout the UK. We have our own fleet of drainage vehicles from 32ton, 26ton, 7.5 ton Jetvac tankers to fully equipped vans with High Pressure Water Jetters fitted. This allows us to react to emergencies fast and effective.

We are specialists in the food industry and have helped many of our customers avoid fines imposed by local water authorities

We would, of course, prefer to assist you in the prevention of problems rather than resolving the problem after the event, leaving you with a huge “clean up” operation.
Therefore we are able to create a planned maintenance programme which reduces reactive call outs and saves money.

We assess all our clients sites and keep an up-to-date register of all drains and access areas to allow us to fix problems fast.

DPG Plus use the very latest CCTV drain survey technology to provide detailed inspections of a drain or pipe system below ground or above ground in areas not readily accessible. Using camera equipment capable of surveying small bore pipes from 50mm-diameter to large bore pipes up to 900mm-diameter we are able to precisely examine and identify any problem areas.

DPG Plus provides a professional CCTV drain survey camera service that can save you time, money and a lot of unnecessary mess when trying to locate a problem. Following a site visit from one of our teams we will provide the results on USB or CD-ROM with a detailed report on the drain condition. We will supply you with a summary of the situation and outline recommendations for problem resolution and the repairs. Once this is provided, a specialist team from DPG Plus will then be available to carry out the recommendations on request.

CCTV Surveying – 25mm to 600mm Diameter Pipework

When problems are suspected in a drain, possibly structural, reoccurring blockages, cross contamination, rodents etc. our trained engineers use a range of CCTV equipment to accurately identify problems, their locations, along with providing cost effective and practical solutions.

Our range of CCTV equipment can operate in pipework between 25mm and 600mm. These units vary in size and capacity with the smallest being a hand held battery operated CCTV unit and the largest being a remote controlled crawler unit that is used to survey large sewers.

On completion of a CCTV survey, a full structural report is supplied, along with a DVD, plan and conclusion, including any recommendations if required.

Drain Relining and Repairs

If there is a structural problem within the drain, then there are two main options of repairing it. The first is by excavating and the second is by using no-dig technology.

Here’s a brief description of when each method is required and what it means to you.

Excavation / Digging

Digging up the ground or excavating is usually the last resort when trying to solve a problem, however sometimes this is the only way to repair the drain or solve the problem.  If a drain has collapsed then excavating is usually the only option, unless diverting the drain would be easier and more cost effective.

If a gully is damaged or broken (such as the one’s that kitchen sinks connect into) then these would be replaced as this is a relatively minor job.

When carrying out this type of work we use sonar tracing equipment to pinpoint the exact location of the problem to ensure that the excavation is being carried out in the correct place with the depth being known before putting a spade into the ground.

No-Dig Technology

More and more technology is being available on the market, which allows drains to be repaired without having to dig up and disturb the ground.  Drain relining is the most common type of no dig technology.

Drain relining consists of impregnating a sock like material with resin and using air inversion to insert it in to the drain.  These resins react together, eventually hardening and sealing the drain.  This process covers holes, cracks and fractures within the pipe, as well as open, displaced joints and root intrusion.  By repairing the drain this way, it seals the drain and also improves the structural integrity of the drain at the same time.

Localised Patch Lining

There are a large number of things that can cause damage to a draining system. Root ingress, as well as water infiltration and the movement of traffic – and even the ground – can lead to open joints and cracks, both of which are likely to get worse as time passes.

Once cracks begin to appear in the pipe, water and moisture can become an issue. This can be extremely damaging to the drainage system. If the surrounding soil which supports the pipe starts to wash away, the whole system can be compromised.

In the past, the only solution to these common issues was to excavate – something which takes time, money and a whole lot of effort. Thankfully, this doesn’t have to be the case anymore. Here at DPG Plus, we’re able to locate the problem and fix it with minimal disruption.

Using Localised Patch lining

Drain lining has been used as a repair technique for a number of years now, but in the past, it was more commonly associated with the renovation of larger spaces, such as sewers. As technology and equipment has progressed, however, it has become a more suitable option for the repairing of smaller pipes.

By lining the inside of a pipe, the hassle and expense of replacement can be avoided. While the whole pipe is often lined to solve multiple issues, this isn’t always necessary. We can use patch liners to increase the support around specific problem areas as soon as they appear – removing the risk of the situation getting worse or even re-occurring years down the line.

Localised patch lining is becoming increasingly popular as a way to deal with isolated defects. It offers an inexpensive alternative to having the whole pipe lined or even excavated.

Here at DPG Plus, we have a wealth of experience and use the latest equipment to ensure a convenient, trouble-free repair service when it comes to patch lining.
