Construction Wood Inspection
How sturdy is the wooden construction?
Stable inside, makes the outside safe

The examination of construction timber in timber, bridge and pile dwellings reveals weaknesses and safety risks.

We evaluate the inside of construction wood

Controls of construction wood in timbered houses, bridges and pile dwellings detect weak points and safety risks. Therefore, regular inspections are essential.

The problem:

Most of the defects or damages are located inside of wooden components and it’s necessary to carry out expensive investigations to detect and identify them.

Because of the current development in the field of timber engineering the exact evaluation of the stability of buildings becomes more and more important. Depending on the operational demands on wooden constructions, one has to distinguish between static strength, impact strength, endurance strength, dynamic strength, hardness and resistance to wear.

Therefore, we have developed instruments that examine the interior life of wooden constructions in detail. Our test and measurement systems will provide you reliable and extensive information about the actual condition of the examined timber component in a quick way. Thus they contribute significantly to the general security.

Little effort – great help

With the almost non-destructive drilling resistance measurement method (IML-RESI System) it’s possible to evaluate the constructional conditions of half-timbered houses, historical and/or listed buildings and wooden constructions. That way, damaged and decayed parts can be detected and exchanged in time. The IML-RESI enables you to make drilling in different heights as well as with different drilling direction.

Only little measurement effort is required to obtain significant information about material properties, structures, interior defects and the thickness of residual walls of wooden beams. In addition to this, it’s possible to determine the stability and residual bearing capacity of load-bearing beams.

Inspection of bridges & pile dwellings in harbours Security risks

A tree over a gorge or a river is the oldest way to build a bridge-thus, wood is the favourite construction material for bridges and therefore bridges or pile dwellings in harbours are mostly built with wood. Because of their bearing capacity that is formidable compared to their little weight, wooden constructions make it possible to bridge very large spans and to achieve enormous heights. In order to grant the security, today it has become imperative to check their residual bearing capacity.

Häufige Fragen zu Construction Wood Inspection

Yes, you can take the information from PD/F Tools or WoodInspector and utilize it in your GIS or other related software.

The wood inspection drill measures the force of the needle turning through the wood product. For example, when the bit hits any soft decay the force on the graph will drop and if the needle hits a hard, brittle decay the graph will spike. If the bit runs through a cavity area the graph will drop measuring no resistance for the bit. The measurements are then collected on either a wax paper strip (F-Series) or electronically recorded for an instant upload (PD-Series).

With the F-Series drill the measurements are recorded on a wax paper strip. Typically users scan the wax paper strip into their report reinforcing their assessment of the wood. The PD-Series drill records the measurements automatically in digital form and can instantly upload these results to your computer via Bluetooth or USB cable. Software is available for your computer to analyze and organize your collected results.

for construction wood inspection

  • IML-RESI MD300
    IML-RESI MD300

    The IML-RESI MD300 is a driling instrument working purely mechanically that does not record a measurement curve, neither electronically nor mechanically. The user feels the result and can read the penetration depth on the 300 mm scale. Often an abrupt and fast penetration is perceptible when the instrument detects a rot zone. Even the annual rings of conifers can be noticed.

  • IML-RESI F-Series
    IML-RESI F-Series

    The IML-RESI F series is driven by an usual drill and is very easy to handle The instrument is cordless and therefore ideal for difficult operating conditions. The measurement profile is recorded simultaneously to the drilling depth on wax paper strip.

  • IML-RESI PowerDrill ®
    IML-RESI PowerDrill ®

    The IML PowerDrill® is equipped with an electronic unit that gives clear support in taking, documenting and evaluating measurements. It can be used wherever reliable and meaningful measurements are required.
