Renderseal Ltd is a Specialist Waterproofing Contractor, recognized and approved by all the leading waterproof material manufactories and leading contractors.
Having successfully operated as a sole trader for five years previously, Terry Blackabee registered RENDERSEAL LTD in July 1999 as a result of a constantly increasing workload and the requirement to employ professional staff as part of a planned expansion program. We have developed a full team including surveyors with CSSW, Contracts Management team, trained site supervisors (SMSTS) and all our site staff hold CSCS Cards and are full time employees, not sub-contractors.

We are able to provide a design and installation service to suit all situations/structures using Sika waterproofing systems and/or Cavity Drain Membranes as well as waterproof coatings, pressurized waterproof injection works and concrete repairs.
