PCP was formed in 2004 to fill a gap in the range of products available in New Zealand to address corrosion issues in the water and wastewater industry. PCP developed an association with Sauereisen in the USA and introduced a range of their products to NZ. Over time PCP were asked more and more to address issues with inflow and infiltration, ground subsidence, potable water solutions, and general construction grouts and resins. PCP researched what was available and sourced the TAM International range of hydro-reactive urethane grout systems. To complete the product offering PCP also developed a relationship with ITW Polymers and Fluids to distribute the Epirez range of construction products including flooring and potable water solutions.
PCP’s focus is on sourcing best materials and developing best application systems. Having great products is one thing but application methodology and application equipment often make the difference between success and failure in a project. PCP staff pride themselves on providing practical and economic solutions and because we understand how to apply the products we sell we source the most effective equipment and accessories to enhance application.
PCP has strong industry connections and if we are unable to assist you with a solution to a particular problem we will often be able to refer you to someone who can. We have a range of contractors we can recommend if you need someone to apply the products.
PCP and its staff support the following industry bodies:
- ACA- Australasian Corrosion Association
- CCANZ – Cement and Concrete Association of New Zealand
- Water New Zealand – The New Zealand Water and Wastes Association
- SSPC – The Society for Protective Coatings USA
- Site Safe NZ
Vitamins and Supplements

Vitamins and dietary supplements are big more than 110 million Americans forked over a collective $28 billion in 2010 on little bottles of would be health magic. Research is unclear, however, on whether shoring up your diet with extra vitamins, minerals, and other supplements helps or hurts in the short run or in reaching for the cheap jerseys china century mark.
For more than a decade, for example, researchers followed more than wholesale jerseys china 35,000 men enrolled in SELECT, a clinical trial designed to see whether taking selenium and vitamin E might help prevent prostate cancer. In 2008, study participants received phone calls and letters: Stop the pills. Not only was the answer “no,” but vitamin E apparently increased the chance of prostate cancer, if very slightly, and selenium seemed to do the same to diabetes risk. Later the same year, researchers from the Physicians’ Health Study II reported that neither vitamin E nor vitamin C reduced the chances of major cardiovascular problems or cancer as hoped.

That so many people seem to believe they need to boost their intake of vitamins and supplements is a triumph of marketing. Most Americans are well nourished (besides being amply fed). Because much of our food is fortified with nutrients, once common deficiency diseases such as scurvy and rickets, caused by inadequate vitamin C and D, respectively, have nearly disappeared in this and other developed countries. Researchers generally believe that with a few exceptions, like pregnant women or the elderly, most people don’t need supplements. Over the 22 year course of the Iowa Women’s Health Study, supplemental vitamin B6, folic acid, iron, magnesium, and zinc were associated with a slightly higher risk of premature death, copper to an 18 percent increased cheap jerseys china risk. Findings were published last year in the Archives of Internal Medicine. The pills, they concluded, are best used when recommended by doctors not for general prevention.

A 2009 editorial in the Journal of the National Cancer Institute, meanwhile, warned that most vitamin studies show no cancer benefits, and that some found unexpected wholesale jerseys harm. Two studies of supplemental beta carotene, for example, found higher lung cancer rates, and folic acid research suggested a higher risk of colon polyps among those taking supplements than among those in a placebo group.
Still, some researchers maintain that the diets of many Americans fall somewhat short on certain key nutrients not enough to threaten a return of those debilitating deficiency diseases, but perhaps enough to call for a little extra help. What follows is the current thinking pro and con on popular key supplements that have been well studied.
Multivitamins. Preventive Services Task Force neither recommends nor advises against multivitamins (or other supplements) for preventing cancer or cardiovascular disease. There’s no need for anything fancy that claims “heart health” or “prostate health” benefits, he says; an inexpensive, basic brand is fine. In 2008, Harvard Men’s Health Watch newsletter editor Harvey Simon recommended against multivitamins. His chief worry was that on top of already fortified foods, the folate in a multi could spur cancer. But a study since then showed that cancer was not increased in women at risk for heart problems who were given folic acid supplements. Simon is now less concerned about breast cancer risk, but prostate cancer still worries him.Articles Connexes：
