J Coffey can assist with a wide range of Basement & Substructure projects, from small residential, single dwelling properties to the high capacity requirements of multi storey structures. Our Basement & Substructure services typically include bulk excavation, muck away, temporary propping and underpinning.

We have long standing and proven experience of basements, subbasements and slabs and from the early stages of your project we will work with you to establish ground conditions. We can assist with soil contamination checks,water table heights and soil saturation.

Our skilled operators and surveyors can assist by providing a Ground Penetrating Radar (GPR) site survey to identify any unmapped services that you may not be aware of.

The range of basement construction work we undertake includes reinforced concrete/precast concrete/cavity filled blockwork/EPS formwork, waterproofing and the installation of waterproof membranes. We also specialise in areas where there is a major water issue by installing a dewatering system. To facilitate this, we have experience in the design and installation of pump stations for the associated drainage.
