Civil Engineering
Durkin and Sons can help plan design and oversee construction projects that include power, road and water projects.
Directional Drilling
Directional drilling provides a trenchless safe method of installing pipes, ducts and cables where conventional open cut methods are not: possible, permitted, practical, environmentally or economically viable. Durkins use this method for:
- Steel or polyethylene pipes from 25mmØ up to 1,200mmØ
- Successfully drilled under areas such as rivers, estuaries, roads, railways, airports, contaminated landfill sites and Sites of Special Scientific Interest (SSSI)
- Conduits can be for: water, oil, gas, electricity, sewerage, chemicals, communication ducts and outfalls
- Ideal for bores from 25 metres up to 1500 metres in a wide range of ground conditions
- Typically a surface launched technique, steered both horizontally and vertically
- Short, medium or long lengths of pipe can be installed without intermediate pits
- Pipes can be installed either straight or curved to steer clear of obstacles
- By boring underground the working area is confined to points of entry and exit only
- No disruption to road, river or rail traffic and no scarring of the landscape
- Equipment works from surface with no need for deep excavations
- DD is quick and in many cases has lower overall costs being unaffected by surface obstacles
- Can be used to install pipes in changeable ground conditions
- Durkin & Sons have the capability to drill up to 1km in length or up to 1200 mmØ
Utility Water Works
At the turn of the century we expanded our field of activities into water industry where we were successful in securing a 3 year term contract with Portsmouth Water for all their mains and services renewal works and in 2005 we were awarded their 5 years AMP Renewals Contract.
We were also awarded an AMP 5 Main laying Contract to August 2015, where works were to include replacement of 125 kilometres of water mains and associated services. This contract included in excess of 25 kilometres of mains re-laid each year along with associated service renewals. All types of main laying techniques are employed including slip-lining, directional drilling and pipe bursting.
In addition to these works we currently undertake domestic water meter installations, as well as Chlorination and testing of all mains and services
Route Feasibility / Studies / Topographical Surveys
Feasibility studies have a number of objectives, firstly identifying feasible routes, secondly to evaluate risk on the proposed route such as structures and any environmental areas of concern; impact on the local area and lastly cost estimates.
Durkin and Sons can also carry out desk-top geotechnical feasibility studies together with geological and geohazard risk assessment.
Traffic Highway Noticing
All our staff are fully compliant and have extensive knowledge on all aspects of New Roads and Street Works Act 1991 (as amended by the Traffic Management Act 2004).
All our staff are proficient with regard to the management of works within the EToN protocols and adept in the use of various Works Management Systems found in this specialist area.
Traffic Management Plans
Durkin can provide full traffic management designs from basic to multi phased complex schemes incorporating liaison with local authorities and other relevant stakeholders.
Highway Reinstatement
Durkin have a specialist highway division offering a range of services to help maintain the highway infrastructure of the UK. We are:
- Acknowledged as one of the South East's leading companies, and have a reputation built on quality and safety.
- We also offer a complete package including design and traffic management
- We not only carry out all reinstatement works for our own highway projects, but also for a variety of other clients .
- Durkin are acknowledged as a leading company with a reputation built on delivering quality work whilst maintaining the highest of safety standards
Route Records
Durkin can provide route records in a number of formats utilising various techniques. Simple line drawings, or GPS capture.
Accurate records of underground apparatus are crucial for prevention of accidents and the health safety and wellbeing of all construction staff who work on the road network.
Measurements are taken so that the route of any cable laid can be accurately recorded, and any deviation noted. Essential information such as type of cable, cable cross sections, duct type, colour, and joint bay locations are also fully recorded.

Haul Road
Soft, boggy wet ground conditions are a major health and safety issue so it is essential that traffic movements on such sites are properly assessed for safe working. Our haul roads are manufactured from sustainable hardwood (EKKI) and are one of the best ways of ensuring worker safety and the safe delivery of material to site with minimum environmental impact
Cables
Durkin and Sons have, over 40 years, established strong links with all the major cable manufacturers and in addition can offer cable system design.
