Proactive planning for full protection

Preventative maintenance is a proactive solution – to avoid reactive problem management.

Once you have quality waterproofing in place, you want it to last.

We use premier products and guarantee our quality, but external factors may impact on longevity.

Surrounded or overlooked by trees? Leaves and debris may block outlets and impact effective drainage.

Other potential problems arise from inquisitive birds picking at membranes or joints, extreme weather, or accidental damage during other trades work. And one problem left untreated may lead to much bigger issues.

Extending Product Life

Extending product life – and warranty

A major benefit of preventative maintenance is ensuring your product warranty conditions are fulfilled.

If membranes are not maintained, the supplier can void the warranty. Keep a membrane in pristine condition however, and suppliers regularly extend warranties… sometimes by years.

Proper maintenance will ensure the membrane retains its original properties, too.

So when accidents happen, or nature takes a toll, your property is protected.

Regular cleaning of a PVC membrane will protect its reflective properties to inhibit heat absorption. And replacement of UV-protective granules in torch-on membranes before they begin to degrade means damaging UV light won’t wreak havoc.

Danrae Maintenance Check

As part of our preventative maintenance, we conduct a full inspection on site.

This is generally every 6 or 12 months but might vary depending on property type and location.

We check drains, seals, welds and membrane. We take photographs, note any issues and provide a full report. And if we see something that needs an urgent fix, we do it on the spot.


Prevention for ongoing excellence

Prevention is the best way forward once we’ve completed your waterproofing project. And we’re happy to help if you already have waterproofing in place.

With decades of experience, we know the ins and outs of waterproofing. And we know that proactive maintenance can keep your quality waterproofing intact – and help maintain your property… and its value.

Danrae Group provides exceptional waterproofing – and we love a happy customer.

We work with strata, hospitals and commercial clients. And we always ensure our clients have the best waterproofing diagnostic, design, repair… and maintenance.
