Concrete Testing 'UKAS'

Get concrete proof of condition & construction

Innovation and the latest NDT technology form the backbone of HTA's approach to Concrete Testing, all backed up with over 30 years of experience and supported by expert lab analysis.

Concrete Testing Experts UKAS Accredited across England & the UK - HTA

Our Concrete Testing work falls into two main categories; first, the condition of the concrete and second the construction details of the concrete itself. These lists are not exhaustive, but give you a flavour of the length and depth of the work we cover.

Concrete condition

Covermeter Survey 'UKAS'
Determine the protective thickness of the concrete covering the reinforcement bars
Half-Cell Potential Survey 'UKAS'
Determine the risk of reinforcement corrosion of the embedded reinforcement
Depth of Carbonation Survey 'UKAS'
Determine Carbonation depth and it's associated risk with reinforcement corrosion
Extraction of Dust Samples 'UKAS'
Ascertaining levels of contaminants in the concrete eg chloride levels
Extraction of Core Samples 'UKAS'
Determining material characteristics of the concrete eg cement, sulphate & alkali contents

Further investigations

GPR Survey
Determine cracking and voidage within concrete
Tomography (Ultrasonic) Survey 1
Alternative technology to determine cracking and voidage within concrete
Tomography (Ultrasonic) Survey 2
High Alumina Cement (HAC) Survey
Visual and sampling survey to determine the presence of HAC
Resistivity Survey
determine the rate of corrosion of the embedded reinforcement
Linear Polarisation Survey
Determine extent of corrosion present to embedded reinforcement
Crack Survey
Determine extent, depth and movement of cracks the latter utilising monitoring equipment
Visual Survey
Assessment to determine visual condition of concrete
Delamination (Hammer tap) Survey
Determine delaminated (hollow sounding) and spalled concrete

Concrete construction

Non intrusive investigations via innovative technology. HTA can determine the concrete construction details while reducing the requirement for intrusive investigations and the large scale removal of samples for testing, enabling you to move forward with confidence.

Covermeter Survey
Determine pattern of embedded reinforcement
GPR Surveys
Accurately determine reinforcement patterns, multiple pattern layers, bar size changes, post tensioned element location and thickness determination of concrete elements
Tomography (Ultrasonic) Survey
Determine via NDT the strength and compaction of concrete
Schmidt Hammer (Rebound/Surface Hardness) Survey
Determine approximate concrete strength

Intrusive investigations

Reinforcement Survey
Necessary exposure to accurately determine bar diameter, type, depth and condition.
Coring Investigations
determine extent, thickness, varying layers of concrete present.
Extraction of Concrete Cores
Compressive strength testing to obtain grade of concrete.
Extraction of Reinforcement Samples
determine tensile strength of reinforcing steel.
Post Tensioned Special Inspections
Exposure of anchors & tendon ducts to determine corrosion plus internal grout condition.
Pre-stressed Beam Details
ascertaining prestressed patterns to beams by combination of excavation and coring.
