NTH’s Value Added
Our experienced professionals deliver comprehensive concrete restoration and rehabilitation services, from the evaluation/investigation phase through development of thorough and structured maintenance programs.
Concrete Restoration & Rehabilitation Services
Specialized knowledge and skills are required for the effective preservation of concrete structures. NTH Consultants provides extensive concrete restoration and rehabilitation services, including the investigation and evaluation of existing structures, design of remedial programs, and quality control monitoring during restoration projects. We provide similar services for masonry construction, including concrete, brick and stone.
Our concrete professionals have vast experience in providing concrete services for above-ground, underground and underwater structures, many of which have historical significance. We have provided services on parking decks; water treatment, water intake and wastewater treatment facilities; tunnels; sewerage systems; reservoirs; office buildings; schools; bridges and service buildings.
Investigations/Evaluations and Design
NTH restoration specialists identify and evaluate the condition of various components in existing facilities, using innovative testing methods to enhance traditional investigation. They prepare contract documents, including an investigation/evaluation report that identifies restoration/rehabilitation program alternatives. Our technical specifications describe the necessary restoration work, plans, bidding documents and advertisements.
Quality Control Services
NTH provides quality control monitoring services that include field observations and testing to facilitate conformance with contract documents.
Our professionals create a maintenance manual for the restored or rehabilitated structure that defines required inspections and identifies who should perform the inspections and at what frequency. In addition, we recommend repair procedures and materials for typical defects that may develop subsequent to restoration/rehabilitation operations.
