As relevant as ever!

Trevor Rushton
Director
Building Pathology Group
Watts

Lists of deleterious materials are forever longer and varied. However, concrete, asbestos and woodwool remain the most common items that may significantly affect the value of a property or the health and safety of its occupants.

The Service typically includes:

1. Concrete

  • Stage 1 Concrete Healthcheck to identify the presence of High Alumina Cement [HAC] and/or chlorides
  • Stage 2 Corrosion assessment of structure and/or concrete cladding where significant chlorides are present
  • Stage 2 HAC Strength and Durability assessment.

2. Asbestos

  • All types of asbestos surveys with advice on condition and repair
  • Preparation of Asbestos Registers
  • Preparation of schemes for abatement works including specifications, tender and contract administration.
  • Advise on management of asbestos.

3. Woodwool

  • Stage 1 Survey to identify the use of woodwool slabs
  • Stage 2 Investigation to assess the structural, fire and corrosion performance where used as a permanent shutter.

4. Other specific deleterious materials.

Why Watts?

Due to its scope of service and network, Watts offers its clients commercially-aware and pragmatic advice. This independent service can be an integral part of a Watts building survey or may be commissioned on a stand-alone basis. The surveys are undertaken by engineers and surveyors experienced in all forms of construction (Concrete and Woodwool) and specialists trained to meet new legislation (Asbestos). The survey reports include an interpretation of results and a focus on the conclusions in a clear and practical manner. Where appropriate, recommendations with costs for remedial works are also given.
