With the harsh NT climate, concrete roofing structures can be susceptible to cracking and leaking. We specialise in all aspects of waterproofing; commercial and domestic. Roof tops, box gutters, bathrooms, basements… No job is too big or too small.

We are also available for general repairs and maintenance for body corporate and domestic projects. We have both the experience and equipment for roofing repairs, painting, concrete pool repairs, bathroom renovations and many more smaller projects.

We’ve rigorously tested different products and only use the best, most cost-effective systems for all aspects of our waterproofing. We are registered suppliers for Gripset, please contact us for pricing.
