Well and Borehole Technologies

To meet the demand of a variety of different clients and project needs, we have adapted a range of well installation techniques that offer maximum flexibility and capability. We have experience working in many different environments and can offer you the best solution to your particular need. See the tabs below for an explanation of each type.
Well jetting is a simple, low-cost and very rapid method for well construction in sandy shallow aquifers. BushProof has years of experience in implementing jetting campaigns and has conducted research proving the viability of this method. Specs: suitable for sandy aquifers with shallow water table; 63 mm PVC casing and screen; geotextile liner; maximum depth of 10 m; ideal for use with Canzee hand pumps.
      The Madrill technique (MAnual DRILLing) has been developed and tested by BushProof in Madagascar. It integrates the best parts of the EMAS and rota sludge techniques. The material is lightweight, inexpensive, and easy to transport to remote locations. Specs: suitable for all types of soils excluding hard rock formations; 150 mm diameter borehole; 63 mm PVC casing and screen; natural or artificial gravel pack; maximum depth of 30 m; ideal for use with Canzee hand pump.  
      The PAT 201 is a semi-manual operated, lightweight and portable rig developed by PAT (Promotion of Appropriate Technology) for use in difficult environments. Specs : mud rotary drilling ; suitable for alluvium to soft rock formations ; borehole diameter 4"-7" (100-190 mm) ; 63 - 125mm PVC casing and screen ; maximum depth 60 m. Allows for installation of both manual or submersible pumps.
      The PAT 301T is a trailor-mounted, compact hydraulic drilling rig for both DTH-Hammer and rotary drilling developed by PAT (Promotion of Appropriate Technology ) for use in difficult environments. The 301T is set up with a centrifugal 14 Hp mud pump or 360 cfm / 12 bar air compressor. Specs : suitable for all soft and hard rock formations ; air / mud rotary drilling (4"-8") ; DTH-Hammer (4"-6"1/2) ; 63-125 mm PVC casing and screen ; maximum depth 120 m. Ideal for a wide variety of applications.
      BushProof can install hand-dug wells where it is more suitable than drilling. These wells are lined with either pre-cast concrete rings or special curved concrete blocks. Depths are dependent on the water level and speed of recovery.
      We have a variety of custom well head designs that include the cover slab, pump support and drainage canal.
