If your building is showing signs of movement, such as cracking of the walls or ceilings it may be due to movement of the foundations from either subsidence or heave.

Structural design

We offer structural design and calculations for steel, concrete and timber beams, joists and lintels, masonry wall panels, roofs and general overall building stability.


We offer our unique “Structure-Only” survey which keeps costs down by limiting the inspection and report to structural and load-bearing elements only.
