GDP  focused on providing Enabling Contracting Services to our clients in various infrastructure and Construction projects. Our thoroughly experienced design engineers ensures in providing economic and efficient Dewatering and Foundation systems. We ensure to provide confidence to our customers that our projects shall be carried out on budget and on time.


  • Sump Pumps, Well Point, Deep Well systems

We provide De-watering system solutions that facilitate in the reduction of groundwater to desired levels thus ensuring site activities are carried on. By utilitizing modeling techniques and considering every aspect of the project , we provided the whole management solution ie. Design , installation , commissioning of Sumping , Well Points and Deep Well systems.

  • 24 hour service, 7 Days week

The nature of dewatering is normally 24 hours a day, 7 days a week, so consequently we have our well equipped and experienced technicians monitoring and servicing the sites 24 hours a day as well as after hours call out crews.

  • Silenced Pumping Systems

In areas where noise pollution are of concern , GDP have the system of installing and commissioning Canopy Pumping systems that reduces the sound levels to approximated 64 dba at 7m

  • Pumping Tests

Our engineers can carry out investigations to determine groundwater pumping characteristics of a site prior to design of an efficient de-watering system. The investigations shall be carried out by pumping tests , falling and rising head test and packer testing. Tests are designed according to the construction design and end purpose of the site to achieve optimized construction design.

  • 24 hour Electronic monitoring and data logging of water levels and flows

Water levels in piezometers and wells and flow rates can be monitored by electronic equipment and to provide near real-time information which can be set to call our and alarm equipment. This also provides accurate information of the dewatering system performance that can be provided graphically online.

  • Modelling

We use sophisticated groundwater modeling software ’s that supports the whole management solution process involved in providing an optimized groundwater control system. Modelling software uses 2D,3D and 4D simulations that allows various site parameters to be taken into considerations such as groundwater behavior, well yields, hydraulic conductivity, recharge, shoring system and so on.

  • Rentals

We provide for the experienced contractors wanting to carry out their own de-watering or pumping works   wide range of materials and equipment in de-watering. Our fleet is up to date and durable.


  • Piled Foundations

Piles are rigid structural elements used in transferring overlaying structure’s lateral , vertical or combination of both loads through weak soil layers to a suitable bearing layer.we provide the following  deep pile foundation techniques.

  • Rotary Bored Piles
  • Driven Piles
  • Continuous flight auger (CFA) Piles
  • Pile Caps and Capping Beams
  • Retaining Walls

Retaining Walls/Shoring are structural systems that ensures to hold back soil or rock from sides of the excavations and forms the walls of  an underground water tight structures for example, basements of buildings.

Retaining walls have to account for a number of factors , the ranges of variables , unknowns and constraints are vast making the designing of the Retaining wall a very complex and challenging task. Combined with proper analysis of geo-technical reports , project requirements and use of design softwares such as ReWaRD and likes , our design engineers ensures to provide the most stable and safe retaining wall system. The following are the systems we provide:

  • Contiguous bored pile wall
  • Secant Bored Pile Wall
  • Sheet Pile Wall
  • Soldier Pile Wall
  • Soil Nailing
  • Anchors and Tiebacks
  • Strutting and Bracing Supports
