Liquid Boot®
Liquid Boot® is a cold sprayed, seamless, polymer modified bituminous membrane (essentially a synthetic rubber) that has been in use in the construction industry in the USA since the 1970s and in Australia since the 1990s. The product is water borne, environmentally sensitive and contains no VOC’s or offensive odours. It has exceptional bonding properties to most surfaces including metal, concrete and geotextiles and provides excellent protection against such things as salt and acid sulphates.
Primary uses of Liquid Boot include waterproof and gas vapour membranes, but it has any number of applications including, but not limited to:
- Conventional waterproofing: below grade walls and slabs, under-slab, between slab, and at-grade waterproofing membranes;
- Potable water liners: canals, ponds, tanks and reservoirs;
- Repairs to leaking structures: roofs, swimming pools, water tanks;
- Brownfield liner/membranes: contaminated soils, landfills and methane gas vapour;
- As well as specialist roofing applications such as Green Roof tanking and sealing of problem roofs including asbestos.
Because it is cold sprayed using simple equipment, it lends very well to sites which may be difficult to access or have complex protrusions and very large areas which require quick laying/curing and seamless application such as dams, water courses, proofing membranes and so on.
