Q What happens if the wrap is damaged or punctured?
A In the unlikely event of the wrap or sleeve becoming damaged, the bitumen provides a secondary sealant that is only damaged by actual cutting of the wood. In the worst case, independent tests indicate a very substantial increase in post life - even with 25% of the wrap cut away.
Q Concreted posts show higher rates of decay than posts in soil. Won't this happen with a wrapped post?
A No, because posts in concrete are initially attacked by chemicals resulting from curing concrete, substantially decreasing resistance to decay. In addition, free entry of ground water and summertime post shrinkage provide the perfect conditions for decaying organisms to enter and thrive, thus resulting in premature post failure.
Q How long will a wrapped post last?
A The life span of the above-ground timber section of the post will be the limiting factor.
Q Is the wrap compatible with all types of preservative treatment?
AYes, the exception is that creosote will cause the bitumen to be softer at room temperature.
Q Will cracks into the wrapped section allow decaying organisms, moisture etc. to enter and cause decay?
A The wrap keeps moisture levels stable and limits lumber from splitting and checking into the wrapped zone to approximately 2", at which point moisture levels are generally below the level where decay occurs.
Q What happens if the post shrinks after wrapping?
A The wrap exhibits elastic properties and can easily cope with post shrinkage.
Q Is the wrap toxic in any way?
A No, the polyethylene is non-toxic and bitumen is classified as a safe substance.
Q Can the wrap be driven into the ground?
A Yes, providing the ground is not excessively stony.
Q Is the wrap resistant to all commonly used chemical treatments, e.g. herbicides and post treatments?
A Yes, the only stipulation is the use of creosote or solvent-based treatments, which will cause short term softening of the bitumen at the top of the wrap.
