Company Background

Founded in 1992, with a background in hydro power and backfill technology, HMT Projects expanded it's business into low, medium and high pressure valve systems as well as imports low, medium and high pressure piping. From the earliest days our company was built on engineering integrity and attention to detail. 

At HMT Projects we wish to create a work environment which nurtures learning and growth and inspires excellence in all we do. We assist our co-workers by sharing knowledge and we are also committed to creating a safe work environment.

Our relationship with everyone we deal with daily is based on honesty, integrity and fairness. We aim to provide our clients with manufacturing and supplying of specialized products for the mining industry at competitive prices with a guaranteed back up of service. 

HMT Plastics began in 2005 as manufacturers and supplier of the 'Certalok' PVC piping system into the civil sector. This product was manufactured in conjunction with the Amercian based company 'Cetainteed'. This neccesitated  the use of PVC plastic extrusion equipment which was subsequently utilised for the mining and agricultural sectors. 

The company obtained the SABS permit to produce these products in 2005 and since then, has grown it's range of products and capacity to where it is today.

The company's central location provides quick and easy access for it's customers, which assists in the building of strong relationships.

HMT Plastics continuously improves it's Quality Management Systems which ensures that they stay abreast of world class technology.

Customer relations and our commitment to community & environmental development

In South Africa and other parts of the developing world, the supply clean potable water is not only a priority but a basic neccessity of life. To make water available, given the limited capital resources, is a challenge in this modern era of pipe materials technology. With this background, several years have been spent in South Africa developing more cost effective piping systems which would meet the demand.

HMT Plastics embarked on a mission to develop and produce more cost effective products i.e mPVC and PE100. We now suppoer the demand of our customers to supply complete packages and provide a service on a 'one-stop-shop" basis.

HMT will continue to investigate possible cross border ventures in areas that require  strong infrastructures for water, compressed air and sewage.
