By | News | No Comments

One of our Environmental Teams working out out of our Eglinton Office was on site recently in Limavady tasked with removing debris from and cleaning a culvert under the Londonderry to Coleraine Railtrack. The work was challenging as extreme caution had to be taken using the correct jetting equipment to avoid any further damage to the culvert’s brickwork. The job was completed over a seven day period to the complete satisfaction of the client.

The transformation in the culvert can be seen in the following before and after images.

Frontline – Montesole Court, Pinner, Middlesex

By | News, Uncategorized | No Comments

The McAllister Group was recently tasked by the London Borough of Harrow with carrying out drainage repair works on two collapsed sections of a 100mm foul water drain which was discharging from Pinner Cricket Club in Middlesex. The repair works involved excavating, exposing, breaking-out and replacing the damaged pipe with new 150mm diameter UPVC pipework. The collapsed stretch of pipe measured 4m. Once the collapsed sections were removed, the entire length of defective sewer which was 50 m x 100mm from Manhole to Manhole was relined. The area was backfilled, compacted and returned to its original state with excess spoil removed from the site.

The McAllister Group in the Community

The McAllister Group was proud to support the Eoin Farrell and James Miskelly Memorial 5k which was held on Saturday 29th July in Rostrevor. The event which was hosted by The Rossi Sports Club –, was organised by friends and families of the friends who were tragically killed in a traffic accident several years ago. Eoin was an apprentice mechanic in the McAllister Group’s garage in Newry where he worked alongside his grandfather Alan Fearon. James worked for Seatruck. Proceeds from the event would be donated to local charity, Cruse Bereavement Care which provides a free and confidential support service for people who have been bereaved, to help them understand their grief and learn how to cope with their loss – Throughout the year, the McAllister Group as part of our Corporate Social Responsibility programme supports a number of charities and events with either a community, arts or educational focus.

Over 500 walkers and 268 competitive runners took part in the event from across Meath, Louth, Dublin, Down, Armagh, Tyrone and Antrim. The winners (in a very competitive field) of the Male and Female adult categories were brother and sister duo, David and Kerry O’ Flaherty. Kerry just happens to be a member of the Irish Olympic Team – so hardly a surprise that she collected silverware.

In the Juvenile categories, the winners were:

Under 12: Boys – Joshua Muckin

Under 12: Girls – Aoife Greaney

Under 14: Boys – Leo Magee

Under 14: Girls – Annie Farrell (who is Eoin’s sister)

Under 16: Boys – No entries in this category

Under 16: Girls – Aoife McGreevy

Under 18: Boys – Thomas Nixon

Under 18: Girls – Chloe Cooper

Prizes were given out by Eoin’s grandfather Alan Fearon (the Group’s longest serving employee) and Foreman Eugene “Gingos” Quinn. Competitors, spectators and organisers had a great day. Members of the McAllister Group took part in the walk and race. The event was a huge draw with some suggestions by participants that it was the best 5K event in the Calendar!

Frontline – The Roddens, Larne, Co. Antrim

By | News | No Comments

The McAllister Group’s Environmental Teams were recently on site at The Roddens in Larne tasked with cleaning debris from three tank sewers which were clogged up. The flow of waste materials within the three 2.2m circular concrete tank sewers was impeded by the debris as it made its downward descent into the sewer network. The slowing down of the flow created a bottleneck which in turn caused blockages in the system.

At the end of each tank chamber there was a valve which could be used to either increase or decrease the flows. Unfortunately, over time the valves had corroded necessitating their replacement. This exercise could not be completed until each chamber was successfully cleaned.

Our JetVac and Tanker Teams were on site for two weeks cleaning debris from the 6 tanks. In total, more than 250 tonnes of waste materials including discarded cleaning and sanitary products were removed from the 225mm concrete channels much to the complete satisfaction of our client.

Frontline – Shanganagh Cliffs, Shankill, Dublin

By | News | No Comments

Our Rehabilitation Team was on site recently in Shankill, Dublin tasked with removing roots before relining on 180 metres of Sewer Trunk main line on behalf of Irish Water. This particular road is lined with trees which lie above the sewer pipe and which run parallel for its entire length. Unsurprisingly one would expect to have a huge risk of root ingress.

Alongside deposits, the ingress of roots into sewer systems creates flow obstacles and can over time cause significant damage to the integrity of the pipes. This problem occurs almost exclusively in sewer pipes which are permanently or partly lie above groundwater or in soil with a limited amount of water. Why? Sewage exfiltrating (leakage) from the pipe will stimulate the outer ends of the roots (a process called hydrotropism) causing them to form new cells in order to grow towards the source of this stimulation. These cells are minute allowing them to easily enter through the smallest cracks, joints and holes in the sewer pipe. Once inside the roots will grow until they block the sewer pipe with lengths of up to several metres. There is a danger that the expanding roots will destroy the immediate area surrounding the original entry point.

Our Rehabilitation Team working on site reported significant root ingress necessitating the use of both the IBG Chain cutting tool and the Group’s robotic cutting equipment. Once the roots were cleared, our team installed 28 CIPP patches and relined 180m of 525mm diameter pipe.

Investing for Success

By | News | No Comments

The McAllister Group, one of the UK and Ireland’s leading environmental solutions providers, has revealed a £2m investment in fleet and machinery over the past twelve months to allow the firm to respond proactively to client requirements on major infrastructure projects across GB and Ireland. Within the last year, the Group has also grown staff numbers to 100+ as the company seeks to further establish its position in the marketplace as one of the Industry’s trenchless technology specialists.

The McAllister Group  has undergone a phenomenal phase of growth in recent years as the company seeks to develop its service offer for major infrastructure, utility and transportation companies. The Group has in recent years established a reputation for the innovativeness of their No-Dig solutions and ability to deliver complex time-bound projects. This reputation has been honed in recent years across Britain and Ireland and has been reflected in the company’s success in winning multi-million major framework contracts both sterling and euro.

Established in 1971, the McAllister Group has evolved from its roots as a drain and cleaning specialist operating in Newry to become established as an UK expert in the application of No-Dig technologies garnered on projects for the UK’s major Water & Sewage Companies (WASCs) and Transportation Companies. The respect for the Group’s expertise resulted in an approach by clients to become involved at the Project Design stage for planned major sewer rehabilitation projects to be undertaken in London and surrounding areas.

To facilitate the delivery of major projects and contracts, the McAllister Group has provided additional support to its teams in Ireland and the UK through the acquisition of a top-of-the-line brand new RECycler® unit, a state-of-the-art Relining Truck, a new Robotic Cutting System, new Jetting Vans, JetVacs  and new CCTV Systems. The Group is working closely with Invest NI to upgrade the company’s IT Infrastructure, work processes and marketing/business development efforts to strengthen the Group’s ambitions for further growth.

The Group has recently moved its base of operations in the UK to Iver which is 15mins from Heathrow Airport so as to be closer to major customers and major ongoing rehabilitation works. In 2016, the Group also opened a North-West office in Eglinton to facilitate both commercial and residential customers in the North West and North Coast areas of Northern Ireland. Commenting on the company’s growth Managing Director Ireland, Peter McAllister said:

“The McAllister Group is very much focussed on building the business and securing further contracts through continuing investment in our people, products and services, building our relationships with existing/new clients and developing and positioning our brand as a market leader locally and internationally. The £2m investment in extending our fleet aligned to the rise in our staff numbers is evidence of our commitment to our customers”

Managing Director UK, Leo McAllister further added: – “Within the last decade, the McAllister Group has opened offices in London to facilitate the development of long-standing relationships with major clients including Thames Water, London Underground and Network Rail. Over the last 10 years, we have developed our experience curve and technical knowledge as a Group working on over 200 projects within London and the Greater London region. We have built a business which has been underscored by excellence in our products, client solutions, service delivery and in the expertise of our employees whose dedication and commitment have been instrumental in our growth”.

Frontline – Camlet Way, Hadley Wood, Hertfordshire

By | News | No Comments

The McAllister Group’s UK Rehabilitation team was on site in leafy Hertfordshire on the 20th June tasked with relining two sewers which lie above the Hadley Wood Tunnel. The tunnel lies on the route from King’s Cross to Shaftholme Junction where trains can reach speeds up to 115m per hour at this point. The two sewers lie just above the railway tunnels – one was a 225mm clay Surface Water sewer which crosses over the Great Northern Railway (East Coast Mail Line) Hadley Wood tunnel which was built in 1850. In 1959 the railway was widened from two to four tracks with the addition of a second tunnel. There is a parallel 225mm clay foul sewer which also crosses the track. Both sewers are 5m in depth but do not pass under the railway. Their proximity to the tunnels are perhaps the cause of the number of breaks, fractures and deformations in the sewers which have occurred from ground movement. The sewers were probably constructed after the original 1850 tunnel, perhaps from 1885 when the area development began but certainly before the commencement of the 1958 second tunnel construction works.

CCTV surveying of the sewers highlighted heavy build-up of calcium scale from the joints. If untreated this calcite build-up can cause multiple problems including reducing the diameter of the sewer by as much as 90% with the formation of both stalactites and stalagmites. In both sewers, the calcite build-up had hardened sufficiently for our team to deploy the robotic cutter. Once removed our team was able to swiftly install 70 m and 90m of 225mm CIPP liner to rehabilitate both sewers. In just over a decade the McAllister Group UK operation has firmly cemented its reputation as an Industry specialist in the rehabilitation of sewer networks for major utility and transport clients.
