Cemplas is a leading specialist contractor in the Car Park Refurbishment sector. Finalists in the ‘Best Refurbishment’ category of the prestigious British Parking Awards for the last five years in succession and winners of the 2022 ‘Best Car Park Renovation’ category, we have repaired, protected and transformed in excess of 300 car park structures throughout the UK for Local Authorities, Shopping Centres & Retail Parks, Commercial Offices, Universities, Hospitals and Commercial Parking Operators such as Q-Park and NCP.



In addition to the extensive work that we carry out on car park structures, Cemplas also have extensive, long-term experience of carrying out concrete repair and protection to a wide range of existing reinforced concrete structures. Typically these have been on exterior building facades such as commercial office buildings, libraries, schools, colleges, hospitals & leisure facilities, to name but a few.



At Cemplas, we have extensive experience in the application of liquid-applied roof re-waterproofing systems gained over a number of years applying the industry’s leading & technically proven systems utilising our own, directly-employed workforce. This enables us to offer substantial guarantees of performance from both manufacturers and Cemplas.



A Cemplas diagnostic survey will identify the prevalent factors, and recommend the optimum solution. The remedy will also depend on the intended use of the basement. If the existing structure is largely sound or to be built (new), Cemplas may recommend a cementitious tanking approach. If an existing basement is in poor condition, cavity drainage using a studded membrane and a pump to drain the water would be preferable. Localised problems would most likely be treated with resin injection.



Cemplas specialises in the application of durable, protective and decorative resin-based floor finishes for a wide range of applications. These encompass sectors such as leisure, education and healthcare through to manufacturing industry (including food production & pharmaceuticals), retail stores, warehousing and commercial & public buildings ALL of which invariably have their very own specific performance requirements.



In order to implement an effective repair and protection strategy to a reinforced concrete structure, it is essential to understand the underlying causes of the defects that the structure is exhibiting. Only once these have been thoroughly understood should the structure undergo a programme of remedial treatment.
