Civil Engineering


Civil engineering is a process which deals with design, construction and maintenance work in both physical and natural environments in the Portsmouth, Hampshire and West Sussex areas. Our own civil engineering contractors can provide expertise in areas of construction, creating roads, landscaping and many other major building projects.


Much of our own work is built around drainage installations, road surfacing and groundwork, although our civil engineering contractors have a flexible approach and can meet the needs of clients throughout Portsmouth on a wide variety of project types. Next to military work, civil engineering is the world’s second-oldest engineering discipline.




Groundwork involves the excavation and preparation of sub-surfaces ahead of major building and construction work in the Portsmouth area. The groundwork contractors at James Hennessy Construction have years of combined experience in this field, and have prepared land ahead of major domestic, commercial and civil engineering work in the past.


Reputable groundwork contractors in Portsmouth will be able to assist with investigative work, site clearances, substructure and ground stabilisation, drainage and earthworks. We have the team, the experience, the plant and the operational capabilities to manage groundwork projects, of any size, at any location in the Hampshire and West Sussex areas.




We are genuine drainage specialists with unrivalled experience in new connections and installations. Drainage plays a key role in the preliminary stages of any major construction or civil engineering project in Portsmouth, and provides land with a safe, sanitary and stable foundation which eliminates possible future problems with sewage and standing water.


The drainage specialists at James Hennessy Construction can provide emergency drainage services on request, and we are also able to repair drainage systems on a contract maintenance basis. Like all good civil engineering contractors and groundwork contractors in Portsmouth, we also specialise in linings, soakaways and septic tank installations.
