Existing Concrete Slabs for Redevelopment

Accurate, independent structural investigations to Irish and European standards.

BHP Laboratories is the largest independent materials testing laboratory in Ireland providing a wide range of engineering & scientific measuring, testing and analysing services to numerous industries throughout Ireland and the UK. We provide a comprehensive range of testing and analysing solutions as part of an assessment of an existing concrete slab.

BHP Laboratories provides these types of services to clients in the construction industry, including main contractors, designers, consulting engineers, owners/developers, and other relevant parties. For an existing concrete slab where someone is seeking information for upgrade works or in the case of issues with construction, see the type of work we complete below.

Services include;

Assessment of existing concrete slabs for development
- BHP provides a one-stop shop for assessment of older buildings and in particular for clients looking to develop new technologies on existing concrete slabs. In most cases, this will include the loading of slabs with much heavier equipment. BHP provides the following services:
  - Site visit and development of proposal for scope of testing and investigation
  - Concrete coring and reinstatement of all destructive testing
  - Insitu Testing of the hardcore and materials below including:
    - Large breakouts, saw-cuts, box-cutting by large diameter coring
    - Excavation of trial pits for inspection and testing
    - Plate Bearing Tests to determine CBR % and K Modulus of Subgrade Reactivity and Approximate Bearing Capacity
    - Dynamic Cone Penetrometer (DCP) probe testing
    - Light Wight Deflectometer (LWD) testing
    - DPH and DPSH Dynamic Probing to 10m to profile the resistance of the ground below the slab
    - Sampling of hardcore fill materials for testing – pyrite, etc.
  - Reinforcement cover and layout testing – cover, spacing, size. Including the use of concrete GPR scanning to determine layout out of multiple layers of reinforcement to a depth of 800mm.
  - Laboratory Testing of cores and samples including:
    - Visual Assessment, Thickness, and Photographic Record
    - Density
    - Compressive Strength
    - Carbonation
    - Chloride Ingress Profile
    - Sulphate Content
    - Cement Content
  - Factual and Interpretative Report

All testing is carried out by experienced technicians on site with results delivered to agreed turnaround times. We can service any location on the island of Ireland with our fleet of fully equipped vehicles and field operatives.
