Good drainage is one of the most important aspects of any building
project, whether that is for a domestic patio or a large building.

If the drainage is right, you can be confident that the resulting building will be on excellent foundations and will not suffer from subsidence.

If the drainage has not been considered or done properly, it could result in subsidence or problems with damp in the building itself. There are many reasons why drainage problems might exist.

These include the following:

> Surface water creating large ponds which do not drain away
> High water tables
> Soil not being able to allow the excess water to ‘seep’ through

To ensure your property is kept dry and does not suffer any problems, good drainage is required, both underneath the building and surrounding it.

SURTEES help you document your drainage requirements (dry-wells, subsurface train, etc.) as well as carry out the work ourselves.
