Groundworks and Foundations in Langley Park

It depends on the ground, the load and what is nearby. Clay, trees and made ground all push the depth down, and the building control inspector confirms the depth in the open trench rather than from a drawing.

Yes, with sensible precautions. Concrete should not be poured into a frozen or waterlogged trench, so we plan pours around the forecast rather than pushing on regardless.

We arrange and pour the concrete as part of the package, using a mix specified for the application rather than whatever is cheapest that day.

It is Durham County Council. People sometimes send paperwork to a neighbouring authority because of the postal address or the historic county, and that costs time rather than money. For groundworks and foundations you will need a foundation design that matches the ground found in the trench, plus coal mining risk where the mapping requires it.

Yes, and it is worth knowing early. The village grew directly on top of a working coalfield and much of it falls within a Coal Authority Development High Risk Area, so a mining risk assessment before foundation work is normal practice here. Where that applies we say so before you commit, not once the trench is open.

It is a report that identifies past coal working under or near a site and what it means for the proposed foundation. Where a site falls inside a Coal Authority Development High Risk Area the local authority commonly asks for one with the application, and in some cases a permit is needed before ground is disturbed.

For a typical domestic extension, excavation, inspection and concrete usually run to a few days, with the timing partly driven by when the inspector can attend and by the weather.

It depends on the address. Solid wall colliery terraces bring their own building regulations questions around insulation and damp, and Durham County Council will look at how a new element meets the old wall as closely as it looks at the new element itself. We check the designation before any design work goes far enough to be expensive to change.

Everything from colliery terraces built for the pit, mostly solid wall construction through to later infill housing on the flatter ground near the village edge. Which of those you have changes the method more than the postcode does, which is why we look before we quote.

We do. Durham, Esh Winning, Consett are all within our normal working area for groundworks and foundations, as is most of Tyne and Wear, County Durham and south east Northumberland.
