Helical piles are being positioned as an alternative to traditional drilled or spread concrete foundations for lattice and monopole communication towers, particularly where uplift, lateral loads and variable soils control design. Screw-in steel piles with helix plates can be installed with smaller rigs, generate minimal spoil, allow immediate loading and are removable at decommissioning, contrasting with large-diameter drilled shafts or pad-and-pier systems that require curing time and substantial excavation. The comparison focuses on sites with constrained access, weak or layered soils, and projects needing rapid deployment or future relocation.

Thames Water has launched procurement for a multi‑lot framework worth up to £177M (excluding VAT) to deliver site investigation surveys across its asset base. The framework will cover intrusive and non‑intrusive ground investigations, including boreholes, trial pits, in‑situ testing and laboratory analysis to support major water and wastewater infrastructure works. Geotechnical and environmental consultants and drilling contractors can expect long‑term programmes tied to pipeline renewals, treatment works upgrades and resilience schemes across the Thames Water region.

Persimmon Homes has partnered with ground engineering technology firm Ecofill to re-use site-won excavated soils as engineered fill in adoptable roads, retaining walls, piling mats, embankments and trench backfills, displacing imported primary aggregates. Ecofill’s process allows classification and treatment of cohesive and granular arisings to meet highways and structural fill specifications, reducing soil sent to landfill and cutting lorry movements for aggregate haulage. The move signals wider potential for specification-compliant reuse of marginal soils on large housing schemes under UK earthworks and highway adoption standards.
