4 Reasons To Call Alpha Waterproofing
Our services
Bay Of Plenty's Commercial & Residential Waterproofing Specialists.
Waterproofing

Using quality brands such as Waterproofing Systems, Ardex, Allco and Nuralite, we can replace, supply and fit all the waterproofing needs you may have for your roof or other areas on the structure. Ask us where waterproofing will be most beneficial for your home or business.
Roofing

For waterproofing your roof, we use sheet- and liquid-reinforced membranes from proven durable materials and methods such as Butynol, TPO, Two Layer Torch-On's and Elastomeric Liquid membranes.
Basement Tanking

To create a waterproof layer in your basement to act as a barrier to incoming moisture, we use Two Layer Torch-On membrane systems, Peel and stick Bitumen Membranes, Single Ply Membranes, Bentonite and various water stop systems. Ask us which one is the best choice for your basement.
Decks & Balconies

Your decks and balconies are fully exposed to the harsh outdoor elements. By adding on a membrane, you can extend the life of your deck or balcony as well as improve the look of it as well. We can do all types of sheet and liquid deck membranes for these projects and will help you choose which option works best for your needs.
Leak Inspection

Can't determine if you need waterproofing or suspect that you have a leak? We also offer an additional leak inspection and detection service to help keep you dry. We'll investigate common and uncommon areas where leaks can occur and fix them on the spot. Let us know if you need a leak fixed.
Sealing

If you have had any tilt slab expansions or joint installations recently, those pieces may not have been sealed yet like the rest of the structure. Don't overlook this area of new construction and preserve what you have just built. We can quickly apply sealant to these types of areas without impeding your schedule or deadlines.
Approved applicators
We are approved applicators for Viking, Nuralite, Ardex, Sealco, Cohe and Special Finishes membrane systems.
