In order to progress a renovation of the studio within a home in Birchgrove, NSW, Patrick Dolan of Pattern Construction Co commissioned Scientific Waterproofing Products to waterproof walls against negative hydrostatic pressure with active ground water leaks (running water). This task was further complicated by the fact that the walls comprised of several different substrates including sandstone-bedrock, clay brickwork previously painted, concrete and cement repairs.
The successful waterproofing process was to
- ignore the active leaks initially
- Saturate all substrates with water, and immediately brush apply two coats of Maxseal Flex – (white in this instance), to the wet substrate.
- Allow a curing period of seven days, and thereafter plug the remaining active leaks using Maxplug, wetting, and recoating that Maxplug with one more coat of Maxseal flex.
Maxseal Flex
Maxseal flex is a flexible, two-component, cement based waterproofing membrane able to withstand 40m negative and 90m positive hydrostatic head pressure, adhering to all porous substrates, and nonporous substrates such as PVC permanent formwork & piping, glass, polycarbonate, metal, and aluminium. Available in grey or white with the ability of tinting to colour match.
Maxplug
Maxplug is a waterproof, non-shrink, hydraulic cement which sets within three to five minutes and therefore able to instantly stop water running from cracks, holes, or other openings within concrete and masonry.
