At AC1 Construction 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.



AC1 Construction can provide you with a full basement package including the bulk excavation, muck away, waterproofing and the Concrete box. We have multiple gangs who specialise in this type of works who work closely with the client to ensure they meet the client’s needs on time and within budget.

Due to the nature of this works and most of the basements we carry out are eventually going to be someone’s future home we realise that changes can be last minute and sometimes without the relevant information but with our knowledge and experience in these kind of works we are able to accommodate this for the client and ensure we make the changes needed.

RC Stuctures


AC1 Construction have been carrying out Reinforced Concrete Frame packages for over 10 years in London and the surrounding areas. We have built up a loyal and experienced workforce; most of which have been with us over 5+ years. We try to use the most up to date formwork systems and ensure that all the workforce have the relevant training, health and safety cards and make sure that all projects are delivered on time and within budget for our clients.

We have built up a great reputation with many clients who use us over and over again. We have great links with companies providing precast elements in which we can combine both precast with in-situ elements on site. This can provide a quicker build and also a higher quality finished product with increased design flexibility on certain elements.
