At MWT Civil Engineering Limited, we help individuals and businesses with our top of the line services. Since starting out, we’ve taken on a variety of projects, always providing personalized attention to ensure precision and satisfaction with all of our work. Take a look at our recent projects and get in touch today to start your own.

Llansannan Flood Alleviation Scheme
Works to divert the foul water sewer, water main and telecomunications cables will begin with the phase 1 of the sewer diversion on April 4th. Works will begin on the junction of A544 and Ffordd Gogar and traffic will be controlled by 3 way traffic lights. Telecomunication and water main diversions will follow over the coming weeks and further information on this will be provided.

For more information, please see our resident’s letters on our Facebook page.

Pont Faen-Concrete Pour
After the Vacuum Excavation had finished at Pont Faen, the first concrete pour took place. Lightweight aggregate concrete with accelerator was chosen.
Pont Faen- Vacuum Excavation
The Vacuum Excavation was a slow and delicate process, as it needed to be tightly controlled to ensure the arches remain equally loaded. This involved the watchful eye of our Engineering manager, John Seed and great communication within the team, working together to keep the balance.
Saint George Quarry
Access improvements at St George quarry for Hanson Aggregates.

The works involve widening the main entrance, as well as kerbing and installing the drainage. The works also involve the construction of a 2nd entrance from the highway, so that office traffic can be separated from heavy lorries entering and leaving the quarry.

It was a very wet and cold start to the job and it’s the first job to put our brand new 15T machine to work.

The Red Gables Project
Red Gables bridge is the bridge that crosses over the A55 and links Penmaenmawr with the beach and promenade.

Pockets of air trapped below the asphalt footway had expanded during hot weather resulting in little humps and bumps in the surface. Small patches have been cut out and repaired in the past, but this time, Conwy council decided to solve the problem by replacing the asphalt surface course with a standard 6mm tarmac.

Our works involved planing off the existing surfacing, undertaking repairs to the concrete substrate and then resurfacing in 2 layers. The final task WAS to seal the surface using a bagged slurry seal.

Conwy Harbour Master
A small job completed for Conwy Harbour Master at Conwy Harbour installing drains to collect the wash out water from the refrigeration units.

This will then be connected to the combined sewer once permission has been granted.

Very tidy work done, in a beautiful part of the area.

Pont Faen Foundations
Pont Faen based in Llangernyw is managed by our Engineering Manager John Seed.

Having completed the foundation repairs and lime pointing to the underside of Pont Faen, works have now started on phase 2. This phase involves the excavation of all the fill over the 3 arches, masonry repairs from above and the installation of a concrete saddle which will strengthen the bridge for many years to come.

Removing the fill from the masonry arches is tricky and we have to make sure that loads remain balanced across all three arches. As this bridge already has longitudinal cracks under the barrels, we installed braces at each arch to hold the sides together when we excavate.

We fabricated the braces in our workshop and here we have the team installing them to each arch using a UB40 Access platform to allow work under the arch without entering the river.

Bryn Bach Installations
Bryn Bach based near Ruthin, is a 200 acre site, which once was the national campsite for the Scouts Association, established in 1930.

Here there is the removal of the under-capacity culvert pipes and the installation of basic steel bridge units on new concrete abutments to replace them. All this is done whilst still maintaining access for local property owners.

Dyserth Waterfalls Road
Works started at Waterfalls road in Dyserth on Saturday the 23rd of October and the lads worked flat out in horrendous weather for 9 days straight, to ensure that the road could be open for the end of the school half term and to ensure there was no disruption to the bus route.
Pont Dolwen Construction
Works at Pont Dolwen included underpinning the existing foundations within the river channel, construction of new river training walls and embankment stabilization. We then excavated the fill from above the arch and replaced it with reinforced concrete prior to waterproofing and resurfacing.
Eirias Park Events Centre
Over a few weeks, we undertook works at the Eirias Park Events Centre for Conwy County Borough Council.
The first phase was to trim and tarmac a previously, rough stoned area behind the grandstand. We then set about building a new platform and foundations for the RGC Hospitality tent to be moved to.
Miners Bridge Construction
The pre-existing Miners Bridge was washed away by floodwater in 2019. MWT recovered what was left of the old bridge from downstream once the flows had eased.
On Friday, we were awarded the contract to modify the existing steelwork and to reinstall this at its original location on new and improved foundations. The bridge is of galvanised steel construction but will be clad in oak, with oak steps and handrails.
Work on site will start mid-November with an expected completion date of the end of January, assuming the water isn’t as high as the picture!
Dyserth Waterfall Bridges
The original “Irish bridges” at Dyserth waterfalls had been damaged by flood water. MWT were instructed to build new masonry faced abutments and install 3 new timber bridge kits between 7 and 9 m long.
The weather conditions were against us, but the lads did a fantastic job, leaving a tidy site that will soon look like no one has been there, except for the great new bridges of course.
We have already had some excellent feedback from the secretary of the Dyserth waterfall who has complemented the works..
Pont Bryn Rhyd-Yr-Arian

2 years ago, the bridge at Bryn Rhyd yr Arian was in a poor state and was damaged by flood water meaning it had to close. Having reconstructed the substructure last year, MWT then went on to win the superstructure contract at the beginning of this year. The project involved the offsite fabrication of the steel spans, lifting into place and then installing a new reinforced concrete deck, waterproofing and highway construction. The whole project went extremely well from start to finish, we used local fabricators, materials suppliers, stonemasons etc, keeping the Welsh pound in Wales. We are very pleased with the end result.
