Cellar Conversions
Cellar conversions are ways of bringing unused poor quality space into habitable use. Sealing a basement from moisture ingress can be carried out using cementitious systems or membranes. In each case we can give a specification to be followed by the contractor or the experienced DIY enthusiast.

Construction Chemicals are UK tanking specialists offering slurry, membrane and basement tanking kits for basement and cellar conversions and all other situations where tanking is necessary.
Tanking Slurry - 25kg

Tanking Slurry - 25kg


Construction Chemicals Tanking Slurry is the ideal waterproofing solution for cellar and basement conversions as well as bund walls. It is also suitable in providing a waterproof damp proofing barrier where damp proof course treatment may not be possible. The product is made up of many components, which give high water resistance, flexibility, salt resistance, good adhesion, set control in a form that only requires water for mixing.

Unlike other Tanking Slurries seen on the Internet this product does not need the addition of an SBR Bonding Agent Our Tanking Slurry has a pre-mixed polymer therefore eliminating the need, and extra expense, of adding polymer (SBR) to ensure optimum performance.

Features
- Tried and tested over may years with no failures
- Tanking Slurry forms part of the original substrate
- High quality polymers give flexibility, salt resistance and good adhesion
- Unlike some products all the ingredients for this product to work are in the bag, the operator only requires water for mixing
- High alumina cement gives good salt resistance

SBR Bonding Agent

SBR Bonding Agent


Construction Chemicals SBR is a white styrene butadiene co-polymer used to improve the properties of cement renders, screeds and mortars. It is also used in conjunction with Construction Chemicals Tanking Slurry as a priming coat or tight render basecoat. Used with sulphate-resistant cement it will resist the movement of salts with in wall. SBR Bonding Agent will increase water and abrasion resistance. It also improves the durability of cement renders and has many other uses.

Features
- Ideal for screeds where under-floor heating has been installed
- Makes renders waterproof and gives flexibility
- Can be used as a primer
- Can be used for stone and concrete repairs

Kair Heat Recover Ventilator - KHRVF 100

Kair Heat Recover Ventilator - KHRVF 100


Kair Trakmaster KHRVF100 Heat Recovery Ventilators provide a continuous air change, replacing stale
moisture-laden air with fresh, warmed air from outside.

When basements/cellars have been tanked and waterproofed condensation can often be problem, Kair
Trakmaster KHRVF100 will control these problems as well as condensation problems in small flats and bungalows and are an integral part of the Kair 'Hybrid' Heat Recovery Systems (See separate data sheet).
Features
- Meets Building Regulations requirements
- Up to 65% Heat Recovery
- Easy to install (no external access required - 102mm core drill)
- Whisper quiet Continuous running trickle ventilation
- Humidity sensor (preset or adjustable)
- Low running costs
- Tamperproof screws (See options for bit required for installation)
- Balanced or positive airflow
- Energy savings
- Security ventilationTM (no need to open windows)
- Health benefit - produces dramatic improvements of indoor air quality
- Continuous Running, Energy Efficient, Heat Recovery Ventilator For Flats, Bungalows, Kitchens and Bathrooms

Unlike conventional extractor fans which suck out and waste expensively produced heat, KairTM Trakmaster KHRVF100 Heat Recovery Ventilators recover up to 65% of exhaust heat, even when operating on boost mode. The world is becoming increasingly aware of the enormous cost of energy production, and this, plus the use of fossil fuels to generate power, is a momentous environmental issue. Extractor fans potentially waste over a million kilowatts of energy every year. This is comparable to the total output of two large power stations. Replacing conventional extractor fans with heat recovery systems could save at least half of that energy loss.

Anti-Salt - 5 Litres

Anti-Salt - 5 Litres


Anti-Salt is a Chloride and sulphate salt neutraliser that converts water-soluble salts into insoluble or hardly soluble reactive compounds.

As a result of this neutralisation, Chlorides and Sulphates, which are present in masonry, cannot be transported by the gauging solution used in slurry coat of tanking seal or to the surface of masonry. This, in turn, prevents salts transferring into tanking slurry when tanking below ground.

Features
- Anti Salt is ideal in barn conversions where salts from animal waste causes problems
- Effective against sulphates and nitrates

Tanking Membrane (Platon Multi) - 2m x 20m x 5mm

Tanking Membrane (Platon Multi) - 2m x 20m x 5mm


Platon Multi Tanking Membrane is a system for damp-proofing and waterproofing rooms and structures below ground level.

This highly impermeable plastic membrane acts as barrier to moisture, allowing you to have completely dry and fully versatile internal floor and wall surfaces and so make full use of cellars, basements or any other areas where dampness and moisture cause problems.

This mebrane can be dry lined on walls, screeded, or finished with a dry board system on floors. Particularly suitable for floors in industrial buildings, as it will transfer loading through screed layers to the underlying concrete floor. Allows contaminated floors to be upgraded.

Features
- BBA approved
- 5mm cavity drain membrane
- fast-track solution for walls or floors
- suitable for use above or below ground
- impermeable to water, gas and water vapour

Platon Stop Flooring Membrane - 2m x 20m x 2.5mm


Damp Proof Underlay for wood and laminate floors laid on concrete

Wood Floor Membrane provides an effective, single-application damp proof underlay for wood and laminate floors laid on concrete. It's equally effective for renovation or new build projects and the tough polypropylene membrane can be laid directly onto a new concrete slab as soon as it is dry enough to walk on. With three times the water vapour resistance than film membranes, it eliminates the need to install a foam underlay. Construction height is only 2.5mm.

Depending upon the moisture content of the floor, Wood Floor Membrane is either fixed with damp resistant adhesive tape or a butyl rubber strip. The wooden flooring material can then be installed immediately.

Features
- No need to wait for concrete slab to dry
- Offers 3 times more water vapour resistance than film membranes
- Fast, single application
- Suitable for use under all wood and laminate floors including glue-free systems
