I saw that I had still had a chance to help get it done right, so I talked with the president of the homeowners’ association and told him we need to make the contractor do it correctly. The housewrap needs to come down over the roof underlayment.Also, since they hadn’t yet cut the housewrap for the window, I printed out the instructions on how to do that, too. Unfortunately, I wasn’t able to talk to the contractor directly at that point, so here’s what it looked like after a few days: RELATED ARTICLESAll About RainscreensAll About Water-Resistive BarriersAll About Wall Rot I don’t think I can ever say it enough, but the building enclosure consists of several control layers and each one has its job. The primary control layer is the one that keeps liquid water out, and it can be a tricky business.Take the case of this condo building (yes, it’s in the community where I live). It’s got several problems, so I went to bat for building science here.We’re having a couple of porticos built, and one day I noticed one of them in the stage of construction you see above. These buildings have no overhang, so that wall will get wet. The contractor put housewrap on the wall and then built the portico. The felt on the roof, as you can see, goes up the wall a bit, but on the outside of the housewrap. Problem?Yes, that’s a problem. Any water coming down on the outside of the housewrap can go right down behind the felt and rot out the framing of that portico. Did I mention the building has no overhang? They did the standard window cut for the housewrap — a big X — then put the window on top of the housewrap and put flashing tape all the way around, on top of the housewrap. If no water ever gets behind the house wrap, this might be OK. On this building, with no overhang, it’s quite possible that water can get behind the house wrap. The tape on top of the house wrap wouldn’t help, and the window framing could rot.They also didn’t fix the flashing detail at the roof. Notice they installed step flashing — but put it on top of the felt, which is still on top of the housewrap. Ugh!Finally, we arranged a meeting with the contractor that I could attend, and we got things straightened out. Here’s what they corrected:We got them to replace the housewrap with a vapor permeable material, not just perforated plastic. (See Matt Risinger’s article and video about this. I’ll write more about it in a future article, too.)The housewrap now comes down over the flashing at the roof intersection.The housewrap comes down over the top piece of window flashing tape. It’s not perfect. They should have kept those nails at the roof intersection above the step flashing that runs beneath the housewrap. But it’s far, far better than we got initially.

People were mocking at the slogan of ‘Incredible India’ for the 2010 Commonwealth Games. On Monday, at the Nehru Stadium, it was ‘Incredible Indians’ as the muscular women answering to the names of Krishna Poonia, Harwant Kaur and Seema Antil swept gold, silver and bronze in discus. When the Indian athletes registered below par timings and distances in the Beijing Olympics in 2008, there was a sense of outrage. Foreign exposure, foreign coaches and still nothing to show was what angered the athletics buffs at home.Two years later, when the Athletics Federation of India has its running battles with the sports ministry over annual affiliation because of certain formalities not being fulfilled, we have to celebrate the achievements of our track and field stars.Agreed, the much-hyped Tintu Luka, coached by P.T. Usha, ran a great 600 metres and then did badly in the last 200 metres and could not win a medal. But then, tonight every sports lover inside the Nehru Stadium was treated to incredible stuff from the incredible women.In the absence of world champion Dani Samuels of Australia, who pulled out of the CWG because of ‘health and safety reasons’, nobody would have thought the Indian troika were the favourites. In fact, expectations were that it would be possibly a fight between South Africa’s Elizna Naude and New Zealand’s Beatrice Faumuna.However, Krishna Poonia’s first effort of 61.51 metres was electrifying and what followed was a pure Indian assault. Coming back to what the Indians have been eating, it is no secret these athletes keep going to Ukraine – Kiev and Yalta – for periodic training.advertisementThey have said the atmosphere for training there is good and food is also quite nice. However, these reasons seem a bit strange as none can complain we can’t provide good food in India.Then again, unlike our Indian wrestlers, boxers and shooters who have been competing in the international arena in a big way, our track and field stars have been very selective in where they competed. In fact, the frequent trips to Ukraine had become a bit mysterious to those who follow athletics closely at home.The ‘Ukraine effect’ has worked wonders and perhaps people need to find out more about it so that other Indian athletes can also excel. Certainly, Indian boxing can do with some such help as the showing this time around has been lacklustre.
DefinitionFlat feet (pes planus) refers to a change in foot shapein which the foot does not have a normal arch when standing.Alternative NamesPes planovalgus; Fallen arches; Pronation of feet; Pes planusCauses, incidence, and risk factorsFlat feet are a common condition. The condition is normal ininfants and toddlers.Flat feet occur because the tissues holding the joints in the foot together (called tendons) are loose.The tissues tighten and form an arch as children grow older. This will take placeby the time the child is 2 or 3 years old. Most people have normal arches by the time they are adults. However, the arch may never form in some people.Aging, injuries, or illness may harm the tendons and cause flat feet to develop in a person who has already formed arches. This type of flat foot may occur only on one side.Rarely, painful flat feet in children may be caused by a condition in which two or more of the bones in the foot grow or fuse together. This condition is called tarsal coalition.SymptomsMost flat feet do not cause pain or other problems.Children may havefoot pain, ankle pain, or lower leg pain. They should be evaluated by a health care provider if this occurs.Symptoms in adults may include tired or achy feet after long periods of standing or playing sports.Signs and testsIn people with flat feet, the instep of the foot comes in contact with the ground whenstanding.To diagnose the problem, the health care provider will ask you to stand on your toes. If an arch forms,the flat foot is called flexible. You will not need any more tests or treatment.advertisementIf the arch does not form with toe-standing (called rigid flat feet), or if there is pain, other tests may be needed, including:CT scan to look at the bones in the footMRI scan to look at the tendons in the footX-ray of the footTreatmentFlat feet in a child do not need treatment if they are not causing pain or walking problems.Your childs feet will grow and develop the same, whether special shoes, shoe inserts, heel cups, or wedges are used.Your child may walk barefoot, run or jump, or do any other activity without making the flat feet worse.In older children and adults, flexible flat feet that do not cause pain or walking problems do not need further treatment.If you have pain due to flexible flat feet, the following may help:An arch-support (orthotic) that you put in your shoe. You can buy this at the store or have it custom-made.Special shoesRigid or painful flat feet need to be checkedby a health care provider. The treatment depends on the cause of the flat feet.For tarsal coalition, treatment starts with rest and possibly a cast. Surgery may be needed if pain does not improve.In more severe cases, surgery may be needed to:Clean or repair the tendonFusejoints in the foot into a corrected positionFlat feet in older adults can be treated with pain relievers, orthotics, and sometimes surgery.Expectations (prognosis)Most cases of flat feet are painless and do not cause any problems. They will notneed treatment.Some causes of painful flat feet can be treated without surgery. If other treatments do not work,surgery may be needed to relieve painin some cases.Surgery oftenimproves pain and foot functionfor people who need it.ComplicationsPossible problems after surgery include:Failure of the fused bones to healFoot deformity that does not go awayInfectionLoss of ankle movementPain that does not go awayCalling your health care providerCall your health care provider if you experience persistent pain in your feet or your child complains of foot pain or lower leg pain.PreventionMost cases are not preventable.ReferencesHosalkar HS, Spiegel DA, Davidson RS.
