Historic tin mine workings are a common problem in the south-west and on one particular location old workings were identified and as a precaution deep resin injected prior to overslabbing with concrete.
The repair solution involved high pressure injection of our environmentally friendly polymer resin down to a depth of 12m and a continuous fill to ground level effectively ensuring the ground had been fully structurally enhanced prior to concrete overslabbing.
Geotechnical testing was carried out on the improved ground with the client proceeding with concrete overslabbing safe in the knowledge that any voids had been completely filled.
Client : Local Authority
A traditional stone structure suffering from water ingress issues.
The Client’s options were to use traditional excavation techniques removing the road surface above, however this option was quickly ruled out due to the bridge being the arterial route into Shepton Mallet and the congested services under the road surface.
The MC waterproofing solution was adopted as a suitable system with all waterproofing works being carried out from the underside of the structure without disruption to road and pedestrian traffic above.
The local authority and their contracting partners have both expressed their complete satisfaction in the MC System and intend to use the technique on future structures.
The Holiday Inn Group were experiencing particular difficulties in maintaining their corporate colour schemes at this hotel due to aviation fuel air pollution, and high levels of bird dropping contaminant.
In effect the building was continually exposed to a build-up of a thin film of the above resulting in an unsightly finish that was not in keeping with their corporate requirement.
Following extensive back to back trials, the MC Color Flair Vision ceramic paint system was selected as a suitable stain resistant solution that resisted contamination from the air borne pollutants.

A series of coal silos required structural enhancement & repair to withstand internal fluctuating loads.
A key aspect of the client’s requirements was for a repair system that was both structural, and fire rated.
NAFUFILL KM250 was selected as it has attained a structural R4 classification and meets with the F120 (120 mins) tunnel fire test.
Additional surface protect from carbonation and pollutants was provided by use of the MC COLOR System leaving an aesthetically pleasing finish.
Client: Network Rail
A 7 span traditional rail over road masonry brick structure suffering from water ingress issues.
Network Rail’s options were to use traditional ‘track up’ waterproofing means, however this solution was quickly ruled out due to track disruption and excessive cost.
The MC elastomer waterproofing solution was adopted as a suitable system with all waterproofing works being carried out from the underside of the structure without disruption or speed restriction to rail traffic above.
Network Rail and their contracting partners have both expressed their complete satisfaction with the MC system and have gone on to adopt this technique on numerous other structures.
Client: Severn Trent Water
A recently constructed Wet Well Pumping Chamber was suffering from severe biogenic sulphuric acid corrosion resulting in the significant loss of concrete section to the gas exposed surfaces within the tank.
The repair solution involved ultra high pressure water jetting to all surfaces followed by grit blasting the host concrete back to a sound alkaline substrate.
Following the above preparation the loss of section was replaced with Nafufill KM250 high strength structurally certificated repair mortar bringing the tank back to original specification, prior to the application of our seemless Ombran CPS lining system that is resistant to the full PH range 0 – 14.
