Merton Cemetery Extension

Summary 

During the course of our contract to design and manage the extension to Merton Cemetery, significant waste management issues arose as a result of the site being located on an unrecorded landfill which contained a variety of wastes, including Asbestos Containing Materials (ACMs).

The Brief 

• Define the extent and nature of the former landfill.
• Determine the most cost effective solution for handling the waste material, with due consideration to ground stability and general aesthetics.
• Undertake appropriate risk assessments to ensure the development was safe.

Our Response

• Ground investigations and risk assessment to characterise the landfill.
• Development of a solution which allowed the majority of material to remain on site.
• Management of the development works in accordance with the ‘Definition of Waste: Development Industry Code of Practice’.

Key Facts 

• Waste screened to remove the coarse fraction and any ACMs before mixing with engineered clay to improve the physical properties.
• Reclaimed waste material reused under the Code of Practice.
