A diagnostic survey will identify the prevalent factors, and Siteseal will recommend the optimum solution based on the intended use of the basement.
Concrete and Structural Repairs
Concrete repairs can greatly extend the life of buildings and car parks. Once the cause of the decay has been identified, with hammer testing, visual survey, carbonation test, chloride test and cover meter test (this records the depth of steel reinforcement below concrete and provides a "low cover" warning).
Condensation has become a serious issue in recent years with greater levels of insulation incorporated in new build housing both raising the average ambient temperature and reducing the exchange of air with the outside. Siteseal supply and fit a range of room ventilators which are energy efficient, quiet and effective.
Siteseal will undertake a comprehensive survey covering timbers and walls to determine the nature and cause of dampness, enabling us to recommend the optimum solution. A diagnostic survey will identify the prevalent factors and take into account the causes of water ingress whether due to chemical erosion, building defects, poor maintenance or simply the absence of any damp proofing measures.
Tanking is defined as a waterproof membrane applied over a surface, preventing completely the entry of liquid water under hydrostatic (water) pressure. External tanking is usually undertaken using a sheet membrane system although various options are available. The waterproofing of retaining walls on single-sided basements, sloping sites or step changes in modular floor construction are amongst the most common works undertaken by Siteseal.
The most common structures to require waterproofing are car parks and podium slabs either as standalone elements or those incorporated as part of a building or wider development.
Timber decay has usually been caused by dry rot or another wood-destroying fungus such as one of the wet rots. Affected timbers should be removed and replaced with pre-treated timber, whilst any remaining timbers at risk of being affected by the rot should be treated with an effective fungicide.
Wall Ties and Fixings
Structural repairs can take various forms; from masonry / render and concrete stitching through the installation of steel reinforcing bars, to the replacement of wall ties be that in the form of mechanical or resin based systems.Find out more
