QuakeWrap® has the NSF approval to be applied in potable water carrying pipes and tanks QuakeWrap® can be applied in potable water carrying systems, using QuakeWrap® VU18C (uniaxial carbon fabric), QuakeBond™ J300SR (saturating epoxy resin) and QuakeBond™ J201TC (epoxy tack coat). Its application however underlies additional restrictions and guidelines. Those differences are outlined below:

Potable water carrying pipes

CURING TIME AND TEMPERATURE

The use of portable heaters is necessary to cure the system for 72 hours at 140 degrees F.

COVERAGE

The approved maximum mil thickness for QuakeBond™ J201TC is 40 mils. Considering a maximum thickness of 50 mils for the saturating coat, this leads to a total maximum dry mil thickness of the system of 90 mils. If the tack coat is applied at a thickness of 40 mil (1 mm) on a smooth surface, one gallon allows the coverage of 40 square feet (1 liter per square meter). Rough and uneven surfaces require more tack coat for the same area.

APPLICATION

Apply QuakeBond™ J201TC onto the substrate with a trowel or spatula to a nominal thickness of 40 mil (1 mm). A notched trowel may be used for this application. Before the epoxy hardens, apply the saturated VU18C to the epoxy-coated surface. The external reinforcement must not be disturbed for a minimum of 72 hours.

Use QuakeBond™ J300SR in conjunction with our saturating machines to impregnate QuakeWrap® VU18C (wet lay-up process); please contact us for detailed information on operation of saturating machines. The fabrics may also be saturated manually. In that case, pour mixed J300SR onto the fabric and use a trowel or spatula to spread the resin into the fabric; it may be necessary to turn the fabric over and repeat this process, ensuring that the fabric is thoroughly saturated. Use a squeegee to remove excess resin from the fabric before installing the fabric on the structural element. The QuakeWrap® VU18C must be saturated by a rate of 50% by volume.

Once the saturated fabric is installed, remove all entrapped air bubbles with gloved hands; a plastic laminating roller can be used as well. Do not disturb installed saturated fabric for 72 hours.

The approved maximum mil thicknesses for the saturating coat is 50 mils. Total maximum dry mil thickness for the system is 90 mils.

The saturation rate of the QuakeWrap® VU18C with QuakeBond™ J300SR must be 50% by volume.

MINIMUM PIPE DIAMETER

The minimum pipe diameter is 36".
