Non Destructive Timber Investigation

Premier Heritage invest in the latest technology for non destructive timber surveys

Micro Drilling for the Structural Assessment of Timber

Many if not all period buildings retain large structural roof and floor timbers, which are vulnerable to moisture penetration, which if undetected can lead to wet /dry rot fungal decay and insect attack, resulting in their structural failure and considerable repair costs. Whilst these defects can sometimes be obvious, where timbers are built into large dimension walls (such as truss ends, bearers etc) deterioration can some times go un-noticed until the inevitable occurs.

What is Micro Drilling?

Micro drilling is a non-destructive investigation technique allowing the structural assessment of timbers and areas that can be hidden or obstructed by decorative finishes or plasterwork and can allow for cost effective care and repair of buildings without the loss of building fabric, which is extremely important when dealing with period or buildings of historic interest.

The Micro Drill cuts a fine 1mm probe into the timber to be investigated and through measuring the speed of penetration, records variations and defects in the timber caused by insect attack, fungal decay or other defects to a computer or field printer, allowing accurate assessment of the timber without the need for full destructive opening up.

This system of non-destructive investigation is of benefit when trying to assess the condition of built in timbers such as truss ends, bearer beams and lintels etc. and can also be used for large dimension joinery timbers. The system can be of great value to Architects, Engineers and Surveyors when proposing conversion, refurbishment and repair schemes of period and historic buildings as it allows minimal interference and the ability to provide conservation approaches to the repair strategy.
