Groundworks in Corby are shaped by the fact that the ground under most of the town was worked before the houses went on it.
Estate development at this scale means made up levels: ground cut and filled when the site was laid out, so that what is under a garden is frequently not the ground that was there naturally. Made up ground can be perfectly adequate to found on and it can be entirely unsuitable, and the only way to know which you have is to dig and look. We put in a trial hole before the design is fixed rather than pricing off an assumption.
Where a plot sits on or near a former industrial site, a site history check is the sensible first step. We are not going to tell you your garden is contaminated, because nobody can say that from the pavement, and we are not going to pretend the question does not exist either.
Trees are the third factor and they catch people out on this stock. The trees planted when these estates were laid out in the 1950s and 1960s are now seventy years old and very much large enough to influence a foundation on shrinkable ground. Their age is easy to underestimate because the houses look modern.
Everything is inspected before it is covered. Our footings and excavation page explains how we approach foundations and site preparation.
