At P. Colohan & Co. Ltd we can provide a full range of groundworks including all types of foundations, drainage and services. We have multiple groundworks gangs who have been working with us for many years who are able to undertake all groundworks to the highest standard whilst ensuring the right solution is implemented to meet the client’s needs.

We work closely with many structural design teams to design earthwork support systems whether it be sheet piling or king post systems on the larger bulk excavations. We also have very close links with piling contractors who have carried out numerous packages for us and we are able to work alongside to get the construction process started quickly.

We carry out all drainage works including adoptable, private, pumped and attenuation and we know how important the installation of the drainage is on our projects. If the works are in the road, we have specialist subcontractors who work on behalf of us who will be able to carry out the works, gain relevant road closures and reinstate the road once complete. We know that few drainage schemes are installed as originally designed and after working in the industry for many years our teams are able to quickly identify any clashes prior to commencing drainage works on site and propose other ways around it.

All our projects have an engineer on site full time which enables us to do all the setting out, level surveys and provide as built drawings as required by our clients. We have great machinery and technologies and strongly believe that you can’t go wrong picking us to carry out your groundworks packages after completing hundreds of packages on time and within budget.
