You might need to find where your drains go if you're planning an extension or moving a bathroom. We can pass a radio location beacon (sonde) through the drain and pinpoint its location on the surface. We can also tell you the depth. This service is available to our customers but also helps us to get things right 1st time when repairs are quoted for. We've had instances where customers have covered their lawns with holes trying to find a drain, however in most cases we can locate a drain to within a few inches and it usually only takes a few minutes!
