Cementitious "tanking" and epoxy systems are a traditional method of waterproofing and can be used as an alternative to cavity drain membranes in certain applications. Cementitious systems are suited to contracts where limited areas are to be treated or where drainage cannot be easily achieved. These systems can also be used in combination with cavity drain membranes, most commonly where headroom is limited or where there is a flat soffit with no drainage falls.

Single component, polymer modified cement "tanking" system for walls and floors
Highly effective damp proof membrane for brickwork, concrete or any cementitious substrate
Surfaces to be treated should be correctly prepared, free from all loose materials and contaminants and be in a sound and solid condition. For application to floors products should be applied directly to the structural slab. For wall applications products should be sandwiched between sand/cement render coats. For all applications, special attention should be given to wall/floor junctions.
NB: Fillet Seal is a pre-packed, cement based and polymer modified product for use as a floor to wall junction seal during waterproofing works when using cementitious slurry coatings and renders. Fillet Seal helps to ensure a smooth transition between horizontal and vertical surfaces which minimises the risk of leaving gaps or holes unsealed during the waterproofing works.
A Lifecote Basement Conversion Project
Under the management of Mr Steve Hawes M.ISRT
Lifecote has the unique ability to transform a cellar or basement from a damp, wet or flooded area into a clean and dry living area!
Your property will be enhanced in both quality and value.
This is what can be achieved by the Lifecote.
The Project is complete.
The property has been valued at £45,000 more than pre-conversion.
Lifecote charged the customer £17,000 + VAT which included all decoration, electrics, heating and flooring.
A substantial discount would be available for tanking only.
In many properties particularly in cities, there are unused lower ground floor/basement or cellar areas, where externally high ground levels to the perimeter, typically to the main front elevation will encourage dampness to penetrate laterally.
When considering the very high cost of property in this region, and with living space at a premium, inevitably it would be considered cost effective to successfully damp proof the basement or cellar area, to form part of the living accommodation, and this would involve internal remedial structural water proofing and associated damp proofing works and replastering.
During any inspection arranged, our surveyor will advise to this regard and specify one or a number of different types of systems which are available depending on circumstances, to successfully eliminate dampness, including considering the most widely used systems involving either a cementatious type chemical vertical membrane or ‘tanking’ application, or perhaps a cavity drain membrane system, which is becoming more popular, involving less initial destruction and preparation works.
The cementatious systems normally require plasters and renders internally to be removed back to the original masonry, and it may also be necessary at the same time to consider incorporating within the cementatious system (or the cavity drain membrane system) a chemically injected damp proof course depending on the external ground levels or adjoining property levels which will be taken into consideration by our surveyor during his inspection.
Generally cementatious systems such as Vandex BB.75 or Triton TT.55 waterproof slurry, require a render coat of washed sand and cement to be applied to the prepared clean brick or stone masonry with the cementatious membrane applied to the surface of the new render as per the manufacturers recommendations in a minimum of two coats (green on green) with suitable overlap detailing between the vertical membrane of the walls with any proposed horizontal membrane depending on floor construction or proposals.
The cavity drain membrane systems, such as Tritons Isola Platon System, provides an alternative to conventional cementatious tanking systems. Cementatious systems work by holding the water back within the wall structure, the cavity drain membrane system works on the principal of allowing water to continue to penetrate the structure, but controlling the dampness in the air gap and diverting it to a suitable drainage point. Depending on circumstances this could involve the installation of a suitable sump pump which may incorporate a backup and failure warning system. This system does not allow pressure to build up against the internal construction, and the air gap behind the membrane allows the structure to breath ‘and to some extent dry’. Membranes are of plastic, type, and are fixed to the masonry using special damp proof seal plugs, sealing tape and rope, with overlap detailing at junctions, which involves minimal preparation required to the substrat. It is often a requirement when installing cavity drain membrane systems however as mentioned earlier, to incorporate within the programme the installation of a drainage sump pump system which may include a back up pump and failure warning alarm.

The Lifecote Cavity Pump Systems
Cement based systems like Sika or our own cementitious applications are only ideal for damp proofing a cellar or basement that does not flood.
If there are ever signs of flooding or even standing Water a Lifecote membrane system must be used.
Simply because where does the water build up go in the Sika or cement based systems?
The answer is it doesn’t go anywhere. The hydrostatic pressure builds up and eventually will displace the cement based tanking system from the wall creating a failure in the entire application.
The financial consequences of a system failure are substantial, small contractors could easy go into liquidation as a result and your guarantee will prove worthless.
All our systems have a fully comprehensive guarantee and our membrane systems are backed by a Lloyds of London insurance policy.
The economics are simple.
If you contract a small firm or an individual to undertake your works for say £8,000 and it fails after 3 years, and in all probability it will, then you will have to pay another contractor, maybe Lifecote another fee to resolve this issue.
Why not simply pay Lifecote initially, to undertake a faultless application, at a highly competitive price and have the complete reassurance of our 30 year guarantee.
Water Based Epoxy Coating
Two coat system comprising primer and top coat
Epoxy based waterproof coating for walls and floors
Suitable for use as a damp proof finish
Water based formulation safe for use in confined spaces
Product can be used as a damp proof membrane where none exists or the original has failed, or as a tanking layer in a "sandwich" construction between sand and cement renders. It is also suitable for use as a durable finish.
Product can be applied to most building substrates and to damp surfaces. When fully cured product resists petrol, oil and mild chemicals. Application can be by brush or roller.
Damp proof membrane and water vapour suppressant
A solvent free, two part epoxy resin coating, typically used as a surface damp proof membrane and a water vapour suppressant. Well suited for use as a water and water proof barrier, beneath raised access floors, in plant rooms and bunded areas. It is also suitable for application on damp surfaces, such as sand/cement and cement floors subject to rising damp or containing residual construction moisture. Product can be used as a general purpose coating for surfaces subject to foot and light wheeled traffic. Product can be applied using a brush or medium pile roller onto sound, clean surfaces.
NB: New concrete subfloors or sand/cement screeds should be left for a minimum of seven days to cure before applying this product.
