Foundations for Difficult Sites

There are good reasons why developers generally steer clear of ‘tricky’ sites. Potentially exorbitant groundwork costs, coupled with prolonged periods of uncertainty, can rapidly transform a viable project into a daring gamble. However, what might appear to be a ‘problem plot’ can sometimes turn out to be a blessing in disguise for self builders willing to take on technical challenges.

The primary role of foundations is to anchor the building to good bearing ground (in other words, ground capable of supporting the building). Even relatively lightweight structures, such as timber frame houses, need to be securely ‘fixed in place’ to resist ground movement.
