WHY IS MY BASEMENT / CELLAR LEAKING?
Damp, dark and dank is the description of many industrial and domestic basements without effective basement waterproofing. They are often large spaces that in their present condition serve no purpose. In fact they can even devalue the property. However underground rooms and cellars can be transformed into stylish living space, storage rooms and workshops quickly and easily. Simple methods can turn basements into bedrooms using waterproof paints, polymer cement coatings and waterproof renders
For example Febtank super and Thoroseal Super are extremely durable waterproof coatings for masonry and concrete. Easily applied by brush to prepared surfaces they provide a highly resistant barriers to water penetration. Both are suitable for both internal and external use, above and below ground level. Their high bond strength ensures long life even when subjected to high water pressure.

Once cured both can be overcoated with cement/sand render or dry lining systems prior to decoration.
Other important systems to consider are;
Sika 1 Pre-Bagged Structural Waterproofing System - Sika 1 mortars are prebatched kiln dried blends of aggregates and cements in 4 grades at the appropriate mix ratios for optimum application performance and durability. When mixed with the diluted Sika 1 liquid waterproofing admixture they provide the multicoat components for the structural waterproofing and waterproof rendering systems.
Structural waterproofing renders and screeds to resist water pressure, below and above ground.
Sika 1 Waterproofer is an aqueous solution of colloidal silicates which swell to block capillaries and pores in cement renders and screeds.
Sika Spritz & Bonding Coat Mortar is a primary bonding mortar for the prebagged mortar systems.
Sika Render Mortar is part of the Sika1 Structural Waterproofing System and is the second layer of the render system.
Sika Finishing Mortar is part of the Sika 1 Structural Waterproofing System and is the third layer of the render system.
Sika Screeding Mortar is part of the Sika 1 Structural Waterproofing System and is a prebatched multi-purpose screed mortar.
Sikadur Combiflex Set for sealing construction joints, expansion joints and cracks comprises of a Sika Hypalon Strip bonded to the substrate by Sikadur 31 CF Rapid epoxy resin adhesive. The Hypalon strip is highly elastic, rot proof and chemically resistant. DWI approved.
Sikadur 31 CF Rapid is a moisture tolerant epoxy resin structural adhesive for use with the Sikadur Combiflex Set.
Compound SBR a versatile highly effective waterproofing additive for sand/cement screeds and renders in basement tanking situations.
Black Jack Black Bitumen Paint - protective coating for above and below ground situations. It provides an effective waterproof, weatherproof and corrosion resistant barrier on a wide variety of substrates.
Sika Damproofing Slurry a cement based slurry used to provide waterproof tanking of concrete and masonry basements
Sikaprufe a multi function bitumen emulsion used to waterproof and protect concrete/ brick foundations, abutments and provide d.p.m’s below screeds
Waterproof Membranes - We have a range of Waterproof membranes, which are self adhesive or pre-formed sheets which eliminate water ingress. These type of membranes are very effective, resisting aggressive ground salts.
Swellable Waterbars - Swellable waterstops are used for sealing of construction joints in concrete cast in-situ.

Thioflex 600 can be used to seal movement joints (contraction and expansion joints) in basements, retaining walls and other below ground structures such as subways.
Supercast SWX is a swellable hydrophilic sealant for sealing construction junctions both horizontal and vertical - particularly around sections of cast in situ concreate, pipe penetrations and other penetrations through the basement or cellar structural floors and walls. Upon contact with water it swells to 200% of its normal girth and fully seals any gap between the penetration and the surrounding structure. See our waterstopping and waterbars page for further information.
Sikaswell S-2 is a swellable hydrophilic water-stopping sealant used in a similar way to Supercast SWX, which again swells upon copntact with water creating a tight seal between materials to prevent water from penetrating into the building envelope.
