Subsidence

Subsidence is usually detected when cracks appear in walls and plaster, doors may become stiff because the frame has moved out of line or floors become uneven. The causes of subsidence include;

• Defects due to faulty workmanship during the original construction.
• Unnoticed problems with the original ground conditions.
• The installation of faulty or leaky drains.
• The growth of tree roots.

Often subsidence is covered by your building insurance and will need to be investigated by your insurance company or their appointed loss adjusters. If subsidence is found, that meets certain criteria, underpinning works or piling will often be specified to repair the property.

BAR Preservation has worked with many loss adjusters and structural engineers to carry out underpinning and piling works.

BAR Preservation is a specialist in the best ways of underpinning walls and property; ranging from mass concrete underpinning to piling and soil grouting.

Shire Stabilisers

Increasingly BAR Preservation subsidence projects include the installation of 'Shire Stabilisers'; a new, innovative approach to subsidence that uses steel tubes driven into the ground.

BAR Preservation has driven Shire Stabilisers up to six meters in to the ground to reach decent, solid ground.

The steel tubes (Shire Stabilisers) are attached to the property in a variety of ways to suit different building types; the method for each building being designed and recommended by the engineers at Shire.
