About Us
Who We Are
R & R Solutions is an independent specialist consultancy dedicated exclusively to foundations and geotechnical construction. We support clients involved in complex foundation works by combining technical expertise, execution insight, and commercial awareness into practical, buildable solutions.
The firm is partner-led and deliberately lean. Our work is driven by senior professionals with long-standing, hands-on experience across the full lifecycle of foundation projects — from early concept development and tender strategy through execution, cost control, troubleshooting, and independent technical review.
Rather than acting as a general advisory, we focus on areas where foundation performance, productivity, risk, and cost exposure are critical, and where decisions must be grounded in real construction experience.
