Prestatyn Retail Park

This £20 million, 165,000 sq ft development in the centre of Prestatyn includes a 50,000 sq ft Tesco, petrol filling station and 114,000 sq ft of nonfood retail for tenants including Marks and Spencer, Next, River Island, Boots, New Look and Costa Coffee.

Complex ground conditions with underlying peat layers requiring utilising a 1.2m thick lime/cement stabilised transfer crust, supported off 1.5m and 2.0m diameter soil mixed columns for the external areas. This chosen method provided a sustainable approach to reuse of existing site materials avoiding substantial excavation/removal to tip and import of quarried aggregates.

Suspended ground floor slabs to the retail units are steel fibre reinforced concrete supported off CFA concrete piles. Foundations are also piled.

A restricted surface water discharge rate has required the installation of several large below ground attenuation tanks supported via soil mixed columns.
