You can rely on us to deliver great workmanship with our fully licensed and trained installers.
90% of our jobs come from repeat customers because we respond quickly, treat each job with care, and only use the best materials for the job.
We understand which waterproofing product is right for each job and are an approved applicator for several suppliers. All our products are trusted to perform – having all received BRANZ appraisal.
For the entire time working with us, you can expect a smooth and reliable experience. Before waterproofing, we always thoroughly check the substructure is correctly prepared. We can be trusted to arrive on-site on time, complete the job to spec with speed and accuracy, and meet your build schedule.
While on-site, we deliver full support to site managers. Once the job is complete, we pass all the necessary information to Council so that it can pass inspection. We also share how to best protect and maintain the products.
For all new jobs, we will issue full product warranties for up to 20 years. We also provide the Council Producer Statement (PS3) and Record of Work (ROW).
We specialise in new residential builds, especially external waterproofing.
