Keller Group PLC
10 April 2006


For immediate release                                     Monday, 10 April 2006


                                Keller Group plc
                        Acquisition of Phi Group Limited


Keller Group plc ('Keller' or 'the Group'), the international ground engineering
specialist, announces the acquisition of Phi Group Limited ('Phi').

Phi is a specialist contractor offering slope and excavation retaining wall
systems to the UK construction market. With expected annual sales of around £10m
for the year ended 31 March 2006, Phi is the market leader in crib retaining
systems. The total consideration for Phi comprises an initial amount of
approximately £5.0m net of cash acquired, with an additional earn-out based on
future profits.

The business will be integrated with Keller's existing earth retaining business,
under the leadership of John Wilkinson, Phi's Managing Director. The
complementary proprietary systems offered by the two businesses, together with
their geographic fit, will give the enlarged business wide national coverage, an
extensive range of solutions and greater capacity to undertake major contracts.

Commenting on the acquisition, Justin Atkinson, Chief Executive of Keller, said:

'We expect continuing cost and environmental pressures to drive a growing demand
for earth retention, as an alternative to traditional but more expensive
solutions.

'The acquisition of Phi positions Keller as the leading provider of earth
retention systems in the UK and will enable us to take full advantage of future
opportunities in this growing sector.'
