Axter uses 3D technology to solve construction problems

Axter site survey

If you are involved in the flat roofing industry, you will be aware of the challenges faced in relation to roof drainage design, especially the need to eliminate ponding water and back falls on flat roofs.

The latest 2021 edition of the NHBC Standards (Chapter 7.1.5 Drainage) now states that a site survey of the deck should be carried out and any back falls addressed prior to handover. To this end, Axter has developed an innovative, highly accurate and cost-effective solution to solve this common challenge.

Axter is working in partnership with a national network of leading surveyors and skilled CAD engineers. They are utilising innovative 3D laser scanning techniques to create highly accurate 2D and 3D point cloud information, plus a 3D terrain map of the roof surface.

This allows them to determine to the nearest millimetre the location of any negative falls and calculate the precise volume of fill material needed to eliminate ponding water and back falls.

This saves time and cost on site, plus it is a targeted approach to drainage fall correction, meaning only necessary screeding takes place. There is also a reduction in the structural load, screed drying times and waterproofing system installation time.

3D laser scanning techniques deployed in this way protects contractor liabilities and ensures compliance with the latest NHBC Standards, British Standards and codes of practice.
