Testing and analysis

Testing and analysis

Our Balvac team can also provide specialist testing and analysis services. This includes:

Pile testing

We specialise in a range of pile testing and analytical techniques. Our comprehensive UKAS accredited pile testing services include:

  • Dynamic pile testing
  • Cross hole sonic logging pile integrity testing
  • Transient dynamic response pile integrity testing

We also offer the following services:

  • Case pile wave analysis program (CAPWAP)
  • Sonic pulse echo pile integrity testing
  • The facility for undertaking GRLWEAP driveability desk studies

Dynamic test data is instantly transmitted to the office from anywhere in the world and analysed using CAPWAP. This facility enables real-time analysis of the pile test data.

Environmental monitoring

We offer a full range of environmental monitoring services with flexible response times to suit your requirements.

They include:

  • Contaminated land
  • Soil sampling and analysis
  • Water sampling and analysis
  • Legionella testing
  • Air quality monitoring
  • Gas monitoring

Diagnostic testing

We deliver structural, diagnostic and geotechnical monitoring for buildings, bridges, car parks and industrial premises. We survey structures to assess the nature and extent of any defects and their probable causes. This allows customers to develop robust repair strategies.

We offer expert advice and site investigations in a range of applications. This includes bore holes, trial pitting, embankment slips, geotechnical diagnosis and failure diagnosis. We also have in-house expertise in soils, rocks and man-made materials.

We specialise in diagnosing the condition of materials in all types of structures including reinforced concrete, post-tensioned and pre-stressed concrete, steel, iron and timber.

We have in-house expertise working with plastics, paints, coatings, cementitious and bituminous materials, epoxies, polyesters and other resins, radionuclides and toxicity of materials.

Structural monitoring

We offer a full structural monitoring service. We use state-of-the-art technology including:

  • Ground penetrating radar
  • Remote crack monitoring, tiltmeters and inclinometers
  • Strain gauging including residual stress measurement in post-tensioned structures
  • Ground remediation evaluation and assessment
  • Ultrasonics
    Magnetostrictive surveys
  • Radiography and tomography
  • Acoustic and frequency monitoring
  • Seismic monitoring
  • Piezometers
  • Thermography
  • Photo-elastic analysis
  • Topographic surveys with real-time triggered alarm systems

We produce bespoke solutions to complex challenges and solve one-off problems. 

Noise and vibration monitoring

We provide a comprehensive range of noise and vibration monitoring services. This includes prediction, measurement and the control of both environmental and personal exposures to noise and vibration.

We also offer:

  • Short and long-term equipment hire
  • Attended or remote monitoring surveys
  • Analysis and presentation of results
  • Monitoring systems

These services are available for all industries or circumstances where noise and vibration are of concern.

Noise and vibration prediction

We provide noise predictions for construction sites using the methodology described in BS 5228 Part 1. Our predictions are processed using the latest version of CadnaA bespoke noise modelling software. Plant specific noise levels are used whenever possible, together with noise levels from the BS 5228 database where actual measurements are not available.

Vibration predictions, if required, are based on previous data obtained by measurement of similar operations in typical ground conditions.
