Hwm Group

What Hwm Group does

HWM Group is a Hampshire, UK-based contracting company that delivers integrated demolition, waste handling, contaminated soil remediation, civil engineering, and soil stabilisation services to commercial clients across London, the Home Counties, and South East England. The group operates four divisions—Demolition (commercial demolition, building dismantling and asset recovery, site clearance, asbestos removal), Contaminated Soil (testing, analysis, removal, treatment, recycling, land remediation, and brownfield development), Contracting / Civil Engineering (earthworks, groundworks, foundations, piling, land remediation), and Soil Stabilisation (added in 2024 via the Envirosoil acquisition, with the Granmat sub-product)—and serves commercial property developers, construction contractors, and public sector clients on redevelopment and brownfield projects.

Underlying technology is centred on a proprietary contaminated soil treatment facility designed by two industry leaders together with HWM's internal team, targeting 'end of waste' status to avoid landfill disposal, complemented by Envirosoil's compact soil stabilisation equipment capable of processing sites as small as 250m³ versus the typical 3,000m³ threshold of conventional stabilisation rigs, plus in-house and external laboratory testing for preliminary geotechnical properties and mix designs. The group owns its own demolition, waste handling and recycling equipment and facilities and runs wash plant operations at Otterbourne through wholly-owned Hazardous Waste Management Ltd, enabling self-delivery on major contracts without third-party rental dependence.

HWM generates revenue on a project-based contracting model via direct tendering, project-based bidding, and prime-contractor subcontracting; pricing is project-quoted and not publicly disclosed. Customer acquisition is sales-led, leveraging the company's website, direct enquiry channels ([email protected]), industry publications including Demolition & Recycling International, and frameworks such as the SFC Framework for fire service projects. The company is privately held by Directors Chris Lynch and Adam Blake, with John Harrison leading operations for the soil stabilisation division, and operates from its Otterbourne Farm headquarters in Hampshire with 11–50 employees.

Core offering

HWM Group provides a full-cycle, multi-disciplined range of demolition, waste handling, contaminated soil treatment, civil engineering/groundworks contracting, and soil stabilisation services for commercial redevelopment projects across London, the Home Counties, and the South East of England. The company owns its own demolition, waste handling, and recycling equipment and operates a bespoke soil treatment facility designed to achieve 'end of waste' status, avoiding landfill disposal of hazardous and non-hazardous soils.

Product overview

HWM Group provides a comprehensive, full-cycle range of demolition, waste handling, contaminated soil, and groundworks contracting services for redevelopment projects. The company operates four main divisions: Demolition Services (commercial demolition, building dismantling, asset recovery, site clearance, asbestos removal), Contaminated Soil Services (testing, analysis, removal, treatment, recycling, land remediation, brownfield development), Contracting/Civil Engineering (earthworks, groundworks, foundations, piling, land remediation), and Soil Stabilisation (including the acquired Envirosoil brand for ground improvement using cement-based stabilisation techniques). The group owns its own demolition, waste handling, and recycling equipment and facilities, providing integrated services from initial demolition through to site remediation and groundworks preparation. In 2024, HWM Group incorporated Envirosoil, expanding capabilities to offer ground improvement on smaller projects (from 250m³) with significant cost and environmental benefits.
