The Details Beneath A Better Build
Good groundworks set the base for everything above, with careful choices around levels, foundations, drainage, access, services and the order of work.
Site Clearance and Ground Preparation
Site preparation can include clearance, excavation, access checks, ground reduction and setting out before foundation work begins. Harpers reviews the site early so the build area is ready for the next stage.
Concrete, Trench and Strip Foundations
Foundations need the right depth, width, concrete specification and inspection points for the build above. Harpers plans trench, strip or reinforced foundation work around the property, soil and design.
Underground Drainage and Soakaways
Drainage affects how foul water, surface water and rainwater move away from the property. Harpers plans pipe routes, falls, inspection chambers and soakaways so the system is practical and build-ready.
Service Trenches and DPC Preparation
Service trenches, duct routes, damp proofing and floor preparation need coordinating before the next trades arrive. Harpers helps keep these details in the right order so the build can move forward cleanly.
Groundworks Costs and Project Timing
Costs and timings depend on site access, ground conditions, excavation depth, drainage, foundations, services, inspections and concrete works. A clear scope helps shape a better groundworks quote.

Frequently Asked Questions
What groundworks are needed before an extension?
Extension groundworks can include clearance, excavation, foundations, drainage, DPC preparation, service trenches and oversite works before the structure begins.
What affects the cost of groundworks?
Cost depends on access, excavation depth, ground conditions, foundation type, drainage, concrete works, service routes and how much preparation the site needs.
Do foundations need Building Control inspection?
Foundation work often needs inspection before concrete is poured. Harpers helps plan the right check points so the base is ready before the next stage begins.
Can Harpers install underground drainage?
Yes. Harpers can install foul water drainage, surface water drainage, inspection chambers and soakaways where required as part of wider groundworks. You can also read GOV.UK guidance on drainage and waste disposal.
What are service trenches used for?
Service trenches help carry ducts or routes for utilities and incoming connections. They should be planned early so later trades can connect services cleanly.
