About AGA Group

AGA Group has further continued its diversification into becoming a multi-disciplined contractor.  In 2005 A.G.A. Group moved from its West Sussex base to Merton, Norfolk.   At that time, it took over Merton Hall Ponds, a sixty (60) acre plant nursery.

Since 1998 the A.G.A. Group have been a leader in projects involving aspects of civil engineering work associated with the construction and refurbishment of dams, reservoirs, canals, embankments flood and coastal protection work and much of the associated infrastructure. The Group’s acquisition of MMG Civil Engineering Systems (MMG) in 2001 further reinforced the civil engineering proficiency of the group.

AGA Group motivates the skills of its people to promote the corporate and social responsibility which is integrated into our business model; this is available in the AGA Group CSR policy (Appendix)

The Divisions That Make Up AGA Group

AGA Bioengineering

Bioengineering has become the favoured method of achieving high standards of effective erosion control, water quality and habitat improvement where a sustainable environmental approach is important.  It helps to enhance the development of its infrastructure, be it motorways, railways or airports. We undertake the rejuvenation and protection of canals, waterways and the landscape using eco-friendly products and systems wherever possible.

Sometimes technically advanced geotechnical solutions must also be incorporated into the bioengineered methodology to make certain the optimum solution achieves the design parameters. Where this is the case AGA Group have the experience to provide integrated Geotechnical and AGA Coir Fibre Systems to fulfil situation appropriate bioengineered solutions.

AGA Group has carried out hundreds of landscape construction, restoration and enhancement programs within the UK’s parks, open spaces, canal network, rivers and SSSI’s.  AGA Group achieves sensitive outcomes by using a combination of natural and living materials alongside more accepted traditional ‘hard’ methods. In many cases ‘hard’ solutions can be completely replaced by a bioengineered ‘soft’ method and where this is not possible bioengineering and landscape techniques can be used to ‘green-up’ and soften the ‘hard’ engineered option.
