How Can I Get Precast Panels On Site Already Waterproofed?
This is an on-line copy of the Precast Presentation Booklet which has proven very popular. If you would like to have a hard copy of the booklet posted out to you, please contact info@allco.co.nz.

Volclay Voltex® at the precast yard. The Applicator checks the plans for the required waterproofing level. The Voltex can be cut with a Stanley Knife in any weather.
An Applicator gluing the corner seam. Volclay Voltex® is also lapped up the form bed to wrap around the corners of the panel.
The lap up the form work can be clearly seen. This will wrap the panel when poured. Volclay Voltex® laps at the joint are 100mm.
Steel work continues as normal. The steelworkers can walk over the membrane.
Completed Reo work. Next step is the pour.
Concrete is poured at the Voltex® end first. This pins the Voltex down and prevents any movement of the membrane.
Concrete vibrators have no effect on the Volclay® membrane.
Once it has cured, the panel is lifted out in the normal manner. Note the complete wrap on the edges of the panel.
The panel is ready for stacking and shipping. Again, no special needs here, just stack and transport as you would any other panel.
Needle punched fibres form a very tenacious bond.
This panel, due to site delays has been exposed in Winter weather for over 5 weeks. The tenacious bond created by the Volclay Voltex® onto the panel prevents delamination.
Panel being placed by crane. A bead of grout is placed between the panel height shims and when the panel is lowered, the membrane is encapsulated.
The Volclay Voltex® membrane is now a seamless seal, ready for DPC or underslab Voltex to lap on.
Volclay Waterstop-Rx® 101T is used as belts and braces in stitch joints. This example is at Maritime 3 Apartments, below sea level, at Auckland's Viaduct Basin. This complete Volclay® Panel Waterproofing System has also been used at the Vodafone 3 Project, adjacent to the Maritime 3 Apartments as well as Project 22 in the same quadrant.
