Sam Pettiford

Sam Pettiford is Digital Growth Manager at Mainline Groundworks. He oversees the company's digital operations, customer enquiries and contractor network, helping route project information so clients and contractors can progress groundworks packages clearly.

His writing focuses on practical guidance for commercial and residential groundworks — including foundations, ground conditions, drainage, site preparation, costs and procurement — drawn from day-to-day enquiry and network operations rather than personal engineering practice.

Mainline's guides and insights are intended to help clients understand groundworks requirements and project decisions. Site-specific technical requirements should be confirmed with the relevant engineer, designer, building control body, authority or contractor.
