Demolition & Groundworks Service Options:
Soft Strip and Site Clearance
Careful internal strip out, services made safe and waste segregated. We clear sites methodically, protect what stays and hand over clean.
Structural Demolition
Targeted demolition of walls or full elements with temporary works. We plan sequencing, isolate utilities and supervise safe removal on site.
Foundations and Footings - Trench Fill and Rafts
Foundations set to design with accurate levels and bearing checks. Trench fill, pads or rafts are poured cleanly and recorded for sign off.
Drainage and Soakaways - SuDS Compliant
New foul and surface runs, manholes and soakaways sized to spec. We set correct falls and backfill neatly, with SuDS friendly options where suitable.
Ground Reduction, Grading and Earthworks
Cut and fill to design levels for a stable platform. We manage arisings, compaction and access routes so follow-on trades can start cleanly.

Ground Knowledge That Keeps You Right
Clear guidance on soils, inspections and agreements before you dig.
Soil Type and Bearing Capacity
We assess soil conditions and confirm assumed bearing with trial pits where needed. This informs foundation choice and depth so your structure is supported from day one.
Building Control Trench Inspection
Foundation excavations are booked for inspection before pour. We share photos, levels and any updates from the inspector so records are complete and sign off is smooth.
Radon Protection Where Required
In higher risk areas, membranes and ventilation measures can be specified. We fit barriers and link details to the slab or oversite so the system works as intended.
Party Wall and Temporary Works
Near boundaries we help you follow the Party Wall process and agree access. Temporary works, propping and shoring are planned so excavations stay safe.
Build Over Agreements
If foundations or drainage are near public sewers, approval is needed. We arrange surveys and drawings, then liaise with the authority so work can proceed.

Frequently Asked Questions
Can you handle both soft strip and structural demolition?
Yes. We isolate services, complete soft strip and control structural removals with temporary works. Waste streams are separated and sites are handed back clean and safe.
How do you set out foundations and levels accurately?
We establish datums, transfer levels and check dimensions before excavating. Foundations are dug to design, inspected and poured with records kept for Building Control.
Do you install SuDS compliant drainage and soakaways?
We set correct pipe falls, chambers and soakaways sized to specification. Where suitable we incorporate SuDS friendly details to manage surface water responsibly.
What if ground conditions are poor or variable?
We review soil type and bearing capacity, then adjust foundation design with your engineer. Options like deeper trench fill, pads or rafts are discussed and scheduled clearly.
Can you coordinate inspections and approvals?
Yes. We book Building Control trench and pre pour checks, and arrange any Build Over agreements. Notes, photos and certificates are included in your handover pack.
