Survey ServicesALS is fully accredited and qualified to perform accurate service location surveys. We use modern devices to determine possible existence of an underground pipe in the area where construction is to be started.

Hydro Excavation – is a scientific and modern way of digging using pressurized water and vacuum. This method exposes buried pipes and cables without damaging utilities. With this modern way, ALS can help to minimise the impact on the local environment and community during excavation works, whilst simultaneously eradicating the risk of costly delays.

Ground Penetrating Radar – a geophysical method that uses radar pulses to develop an image of the subsurface stratigraphy. This reliable and non-destructive locating uses electromagnetic radiation which detects and reflects signals from subsurface structures to create an image. GPR can assist with several applications such as stressing cables, conduits, reinforcing support structures, fibre optic cables etc. ALS team are expert and well-trained in reading the feedback given by the machine.
