Affordable and reliable groundwater compliance
Sensatec is a leading entity in offering environmental solutions and services for contaminated soil- and groundwater. Sensatec was established in 2005 and has a track record of over 500 successful remediation projects.
Our primary solution In-Situ Remediation is applicable to resolve soil and groundwater contamination challenges for industrial-, mining- and petrochemical sectors as well as addressing groundwater contaminations within the water supply.
Sensatec Africa brings together the long solution specific expertise with local
knowledge to service the African market.
A value-adding contractor
We bring OEM in-situ remediation plants, monitoring- and management technologies to your site and take care of the operations, maintenance and remediation management on your behalf.
Our multidisciplinary scientific engineering team has the capacity to drive or contribute towards site-specific investigations, analyses and solution design and adjustment processes.
Solutions for African conditions
Affordable and reliable groundwater quality that is environmentally compliant – you pay for the outcome, not pumps and pipes.
As a semi-passive and low energy consuming methodology – strong contribution towards ESG’s and Zero Carbon.

In-Situ Remediation
Applicability: Contaminated soil and groundwater
In-Situ Remediation means that the contamination challenge is resolved underground by injecting safe reagents to trigger and accelerate bio-chemical remediation processes.
As a rule, there will be no need to excavate or pump-and-treat. We offer a low risk phased approach to determine the solutions suitability and business case.
- Reactive barriers
- Source zone remediation
By far the most cost-effective method for contaminated soil- and groundwater.
In-organic Contaminants
Industries: Mining, industrial, bulk water supply
Mine-water contaminated groundwater origin is typically from tailings storage facilities, waste rock dumps or processing operations. Contaminations are often characterised by elevated sulphate, nitrate, metals and metalloids. Inorganic contaminants can also come for example from industry, wastewater infrastructure or unimproved sanitation.
Sensatec can stop the contamination plume from advancing by implementing a reactive and permeable barrier – where the contamination is neutralized or immobilized while the safe water continues its flow.
Sensatec can target the source zones for lasting solutions.
By far the most cost-effective method for contaminated soil- and groundwater.
Organic Contaminants
Industries: Petrochemical, industrial
Organic contaminants origin is typically in industrial operations and their value chain. Contaminations are often characterised by hydrocarbons, petroleum hydrocarbons, chlorinated solvents, pesticides, herbicides, PFAS and similar contaminants.
Sensatec implement a reactive and permeable barrier to prevent plume from advancing or targets the source zone directly at contaminated sites.
By far the most cost-effective method for contaminated soil- and groundwater.
