Substrate check and preparation
Ensuring the floor and wall substrate is sound, clean and prepared to accept a membrane.
Wet Area Waterproofing
Laundry & Wet Area Waterproofing Sydney
Membranes for laundries and internal wet areas, including new work and remedial repairs.
Laundries are often overlooked. They are smaller than bathrooms, they get less attention during a build, and yet they contain a washing machine, a tub, floor wastes and plumbing connections — everything needed to release a large volume of water at once. Diamond Seal Waterproofing waterproofs laundries and internal wet areas across Sydney.
Wet area waterproofing also extends to other spaces where water is expected or possible: internal drying areas, utility rooms, and areas around plumbing fixtures. Where a kitchen has particular water exposure or sits above occupied space, waterproofing may also be relevant there, and can be discussed as part of the scope.
Why laundries and wet areas need attention
A hose failure or an overflowing tub in an unwaterproofed laundry sends water straight into flooring, wall frames and, in apartments, the unit below. Unlike a slow bathroom leak, this happens in minutes.
Day to day, laundries also deal with splashing at the tub, condensation, damp floors and constant humidity. Over time, that combination degrades unprotected substrates, encourages mould at the wall base and lifts skirtings and joinery kicks.
What laundry and wet area waterproofing involves
Priming
Applying the appropriate primer so the membrane bonds to the substrate reliably.
Junction and penetration detail
Bond breakers and reinforcement at floor-to-wall junctions and around wastes, tap sets and machine connections.
Floor and wall membrane
Applying membrane to the floor and to wall areas exposed to splash and fixture contact.
Falls to the floor waste
Confirming the floor drains to the waste so overflow water is directed away rather than held.
Curing and protection
Allowing full cure and protecting the membrane from damage before tiling or the final floor finish.

Benefits
Protects against sudden overflow
Waterproofing gives a laundry a chance of containing a hose or tub failure instead of spreading it.
Reduces long-term damp damage
Constant humidity and splash exposure do less harm when the substrate is protected.
Small-job friendly
Laundries and small wet areas are worthwhile jobs, not an inconvenience.
Consistent with bathroom work
Same detailing standards applied across all wet areas in the property.
