    Our paving was looking dull due to stains caused by cement spray. The staff at Tech-Dry were extremely knowledgeable and helpful, and recommended their Australian made product called Protectaseal, which was easily applied using a garden sprayer. This product brought the colour of our pavers up like new and will also protect them from future staining, so I could not be happier with the quality of the product, the ease of use and the friendly service I received from this Australian owned and operated company, Tech-Dry.

    I just called Tech Dry to clarify how to go about installing a damp proof course in my old house which is also a rental (short time from to get work done). I could not have had a more helpful person take my call. Knowledgeable, brought up points I needs to consider, time frames etc, other options to make it comfortable for tenants while the walls dry out, how to deal with salt and paint flaking. I only wish more people were this helpful when planning renovations. You have now made what felt like an insurmountable task feel achievable! Thank you!

    We had rising damp in our old Victorian style town house. The DPC Cream from Tech-Dry did wonders! Would recommend to anyone!
