Borehole Casing and Construction in Zimbabwe

Materials to be used in Borehole Casing and Construction For Borehole Drilled in Zimbabwe should be given due consideration. 

Casing PVC Casing is relatively inexpensive and resistant to corrosion but is easily damaged by Careless Pump Installation or Service Work. 

Please Note: There are several types of PVC piping available, but not all are suitable for use in Casing Boreholes. Any PVC materials must be manufactured in accordance with the Standard Association of Zimbabwe, that clearly marked the standard, and must be rated in accordance with the application. 

Fibreglass reinforced plastic (FRP) and fibreglass reinforced epoxy (FRE) are more expensive and stronger than u-PVC and are usually specified on large diameter and deeper bores. 

Steel is the strongest casing material, but it is more expensive and subject to corrosion in some areas. It is the material generally used in Deep Boreholes to withstand construction and installation stresses. When corrosion is a known factor, stainless steel can be preferred and is available in different grades and wall thicknesses. 

Most boreholes will last generations, as long as they were Drilled and Cased properly in the first place. 

Some boreholes that were drilled in the 50s or 60s can feasibly still be functional. If you have a new borehole drilled, especially by a trusted contractor, it is lined with approved Brands and tested Borehole Casings only.

We use Proplastics Zimbabwe (Class 9 Casings) and Driptech Irrigation (Class 10 Casings). These Casings are tried and tested and have a 50-year warranty. According to Proplastics Zimbabwe - they provide at least a fifty (50) year guarantee on all its products. Especially the Class 9 and 10 Casings when it comes to Borehole Casing.  Our Borehole Drilling and Installation Services cover all areas in and around Manicaland Province which include Buhera, Chimanimani, Chipinge, Makoni, Mutare, Mutasa, Nyanga and Rusape.

Borehole Casing and Construction in Zimbabwe

Using the correct Borehole Casing from approved brands will ensure the Borehole will not collapse ... and with modern drilling techniques and skilled workmanship, a borehole is likely to last for many years.

Next time someone offers you Cheap Borehole Drilling prices, don't just ask about the type of casing, they will be using, but be sure to also ask about the brand they use.

• Know your casing brands and their value.
• Poor quality or low-valued brands also contribute to low pricing.

DripTech Irrigation gives an assurance that all its Pipe products, this includes Borehole Casings, have been certified by the Standards Authority of Zimbabwe and are compliant with the South African Bureau of Standards. This means the Casings have been approved for use in Boreholes Water Systems and provides excellent chemical resistance.

Only the best raw virgin materials go into the production of the Casing and this is to ensure the strength and longevity of your Borehole when correctly Cased.

Borehole Screens: If your water comes from a sand aquifer, good quality Borehole Casing and Screen is recommended. Whilst these can be expensive, they are a long-term investment. A well-chosen Borehole Screen will increase the yield of the bore, and help reduce pump wear and maintenance over the life of the bore. 

A Borehole That Lasts A Lifetime! (Know Your Borehole Casing)

Borehole Screens that offer maximum open area reduce entrance velocities, thus reducing corrosion, encrustation, and sand pumping. Boreholes that have high-quality Borehole Screens installed generally require less development.

Slotted PVC are common in Zimbabwe and are suitable, usually limited to low yield requirements. 

Gravel Pack: Where very fine sand is encountered, a gravel pack filter envelope may be recommended. This allows a screen with larger apertures to be used and therefore better yields to be obtained.
