RSK Group of Companies

RSK’s materials and structures team has been at the forefront of construction material condition assessment for over 30 years. During this time, we have gained unparalleled experience evaluating different types of structures, environmental exposure conditions and deterioration mechanisms.

Depending on your requirements and the characteristics of the assets involved, we can provide the following key services:

• Full structural investigation of modern and historical structures, with associated building surveys, to reveal the detailed design principles and quality of past workmanship
• Consultancy at the preconstruction design phase and of existing buildings to determine causes of failure and assess suitability for refurbishment works
• On-site testing, including facade condition assessments, load testing, leak detection, pull-out testing, and covermeter surveys
• Petrographic examination of various materials, including concrete, mortar, plaster, screed, aggregate, building stone, roofing slate and ceramic building material
• Chemical analysis of construction materials including concrete, mortar, render/plaster, bricks and paint to establish a range of properties such as composition or the presence of deleterious materials
• Physical and mechanical testing of concrete, mortar, render, natural and cast stone, roofing slates and tiles, including compressive strength of concrete, slip resistance and abrasion resistance of dimension stone
• Deleterious materials surveys, including identification and evaluation of alkali-aggregate reactivity, chlorides, high alumina cement (HAC), reinforcement corrosion and sulfates in concrete and calcium silicate bricks
