BOSA Contracts have undertaken several contracts for ourselves, involving the waterproofing of basements using the SIKA system.  Their attention to health and safety issues, training, workmanship and levels of communication is highly commended.  As a well performing subcontractor we look forward to working with BOSA on future contracts.

As a site manager it’s a pleasure working with subcontractors who you can rely upon to carry out their work safely, to quality standards and to programme.  BOSA Contracts Ltd met these objectives in every respect and I would have no hesitation in recommending them for future work.
