Liquid Membrane for Basement, Retaining Walls  :   

     
Latex Rubber Modified Bituminous Liquid Membrane
 
is a liquid applied, latex modified bituminous elastomeric waterproofing membrane which, when fully cured, forms a permanently flexible waterproof lining to most building surfaces including reinforced concrete, block work, brick work and cement render. Single component, user friendly. Simple application - brush, roller or spray. Excellent elasticity. Seamless. Low odour, non toxic water based. Fast curing.
Polyurethane Retaining Wall Liquid Membrane
  
Multithane Vertical is a tough, durable, elastomeric, single pack, liquid applied, moisture curing, cross-linking, polyurethane waterproofing membrane - usually grey in colour.
Solvent Free Rubberized Liquid Membrane
 

Emer-Proof Ecoflex is a high performance single component water based rubberised waterproofing membrane. Developed for the Residential & Commercial construction industry. It is solvent free, non-flammable, and forms a highly flexible monolithic waterproofing membrane.   Waterproofing of: Retaining walls, Planter boxes, Basement walls, Garden beds.   Waterproofing / damp proof sandwich membrane.   Repairing fine cracks and crazing of asphalt surfaces.   Key joints and dowel bars.   Patch and repair of old bitumen membranes.   Adhesive for polystyrene protection boards.

 
Water based Latex Rubberized Liquid Membrane
  
Durabit Reo a water based, polymer emulsion waterproofing membrane which incorporates micro fibres thereby internally reinforcing the product. It is a modified Durabit EF membrane with the addition of the micro reinforcing fibres. It meets the criteria of AS4858:2004 Wet Area Membranes. It is an elastomeric, environmentally friendly membrane designed for both internal and (non-exposed) external application. It cures to form a durable, odourless, impervious, seamless membrane that resists re-emulsifying after it has fully even if immersed in water. It is available in white, black, grey and blue,minimum quantities apply, does not stain grout or tiles and has excellent resistance to hydrostatic pressure.    
 
Flexible Cementitious Retaining Wall Liquid Membrane
 

Crystoflex is a two part waterproofing membrane comprising of a liquid component of selected polymers and a powder component of selected cements, fillers and aggregates. When mixed together to form a brushable or rollable slurry it provides a strong, hydrostatic pressure resistant, flexible waterproofing membrane with particular application in immersed or ponding situations.    It complies with AS/NZS 4020:2002 Testing of Products For Use In Contact With Drinking Water - Australian Water Quality Centre Report Number 4007/92.1595.


Sheet Membrane for Basement, Retaining Walls:  


Wrimco 3mm Torch Sheet Membrane
 
It is ideal for installation as a roofing or tanking membranes, offering an optimal adhesion on a variety of substrates. It can be used on flat, vertical or pitched surfaces. It is available in 3mm and 4mm plain (either Sand or PE film topside), as well as a 4mm mineral in a natural Slate Grey.
NP180 Base Torch Sheet Membrane
  
Modified PLUS NP180p/p Base Sheet is designed for use as the base or first ply in a high performance two-ply modified bitumen system, or as a single ply when not exposed, and for fillets and detailing. Main applications are for tanking, balconies and roofing and for waterproofing of planters. 
Sopralene Flam 180 Torch Sheet Membrane
 
It is a high quality, elastomeric, sheet waterproofing membrane composed of Styrene-Butadiene-Styrene (SBS) thermoplastic rubber with non-woven polyester (180g/m2) reinforcement and high quality bitumen. The top and bottom surfaces are covered with a thermofusible plastic film thus facilitating its installation using a propane torch. It is designed to be the base sheet ply in two-ply modified bitumen systems or as a single-layer system when double layers of the material are used at all transitions, drains and corners. Typical applications include decks, tanking, podiums, planters, roofs and bathroom floors. 
 
Retaining walls are very similar to planters but without the bases. They may be critical such as when the other side is a habitable room, or relatively non-critical such as a garden wall to stop the paint cracking off. Here the membrane is on the outside of the wall rather than on the inside but the same principles generally apply as for planters.    
 
New Retaining Walls Construction    
 
A core filled blockwork wall is normally open at the top when waterproofing is required. The first thing to do is to cement flush where the core fill has shrunk and waterproof on top with virtually any membrane to hand as this helps to reduce the porous block from becoming saturated every time it rains.    
 
Liquid applied membranes will only work if the mortar is properly struck and flush. Vertical grade pure urethane such as Multithane HV or bitumen urethanes such as Duroproof PU have the best properties but water based SBR latex, latex bitumen and acrylic/cements are very popular. However torch applied SBS is safest and very long lasting and has the advantage with expansion joints, and also where the face of the blockwork wall is flush with the face of the footing as all that is required is an extra strip over the cold joint.    
 
Membrane can be protected by: Cuspated protection board, XPS Polystryene board, Corflute board and Geotextile drainage sheet.
 
Where drainage sheet is used, terminate it at the top with a flashing profile to help hold in place and to keep water from travelling between the dimples and the membrane. Wrimco supplies 8mm and 10mm dimpled drainage sheet with integral filter, the 10mm has a higer flow rate and volume.               
 
Repair leaking retaining walls    
 
Assuming it is impractical to excavate the dirt and start all over again, or there was insufficient room to apply the membrane externally, then the wall has to be made watertight from the inside. If blockwork is used and the wall is saturated, then you just have to wait for it to become reasonably dry for the crystalline type coatings and special cements to bond and seal the surface; and similarly with the acrylic cements which will also handle a degree of movement or cracking in the substrate. Water based epoxies (WBE) also find application here either on their own or as a primer for the acrylic cement.    
 
Unfortunately none of the normal membranes such as SBS, APP, PVC or any of the liquid applied membranes or urethane sealants remain adhered to a wall that is permanently damp unless first primed with WBE.
