Waterproofing & Roofing Services in Bay of Plenty

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.

Sealing joints on new construction

Tilt slab buildings are made from large concrete wall panels, and the joints between them have to keep water and wind out while the building moves. Those joints are sealed once the panels are standing, which is why they are easy to miss in a busy programme, and why we fit around yours.

Sealant is not a forever material. BRANZ Bulletin 584 puts the life of a sealant exposed to the weather at 15 to 25 years, so it will need replacing during the life of a building, and says sealant joints should be accessible for checking and maintenance. Getting the joints sealed properly at the start, and checked over the years, protects what you have just built. If a joint or junction is already letting water in, a leak inspection finds where, and our membrane waterproofing services cover the roofs, decks and gutters around it.

Frequently asked questions

How long does joint sealant last?

BRANZ puts the life of a sealant exposed to the weather at between 15 and 25 years, so it needs checking over the years and replacing during the life of the building.

When should the joints on a new building be sealed?

Once the panels or other components are in place, and before the building is handed over. It is a step that is easy to overlook in new construction, and leaving joints open lets water and wind in.

Will sealing hold up the build?

No. We can quickly apply sealant to these areas without impeding your schedule or deadlines, and we plan the work with you.

Are your staff trained to work at height?

Yes. Every technician is trained in height safety and carries a site safety card, and Alpha is Totika accredited for health and safety prequalification.
