Landfill Capacity Expansion

With a shortage of suitable space with Planning Approval for landfill, there’s more demand than ever for additional waste to be placed over existing sites. Having originated in the US in the late 1980s, this practice is now sometimes known as ‘piggy-backing’, and needs a base containment lining system to be placed over the existing landfill. However, this will need structural support to control deformation caused by decomposition settlements in the underlying waste – the development with time of voids created by the collapse of large hollow objects such as rusting refrigerators needs to be considered.



What Tensar geogrids can do

Tensar’s uniaxial geogrids can reinforce the new lining system and  can be designed to safely span the anticipated voids without imposing excess tensile strain and therefore damage of the liner. 

Whatever your landfill project, we can help

Tensar’s innovative technology has been used in projects worldwide, and a full range of case studies and brochures is available. We can also provide full technical support including expert advice, specifications, drawings, certified designs and details of pricing. Specific services are available by contract.

Improving landfill space – with Tensar technology

Tensar’s uniaxial geogrids can reinforce the new lining system and  can be designed to safely span the anticipated voids without imposing excess tensile strain and therefore damage of the liner. 

How you benefit

Incorporating a Tensar geogrid layer into the lining system offers several benefits:

Maximise disposal capacity: extra disposal capacity can be created without using additional land space and aiding Planning Approvals

Extend the life of existing landfill sites: buy adding new capacity, the life span of existing waste disposal facilities can be extended
