    Fin24.com | From zero maintenance to total destruction - January 9, 2015 by Mr HomeBuilder

    Cape Town - A Fin24 user laments the state of his hometown ofVereeniging that, with three rivers running through it, could have easily be a major tourist attraction.

    Vereeniging is part of Gautengs Emfuleni Local Municipality in the Vaal Triangle. It was in the news recently, after it was reported that the municipal manager earns R200000 a year more than President Jacob Zuma, according to City Press.

    Sam Shabalala (52) pockets R2.8m each year, making him South Africas most well-paid municipal manager. The municipality, which includes Vereeniging and Vanderbijlpark, services 722000 residents and has a budget of R3.9bn.

    Fin24 user Greer da Cruz writes:

    It really pains me to write this letter, because believe it or not, I actually love my town, Vereeniging in the Vaal area. I was born and bred here. But today I look around and think 'hellhole' because there is no other word to describe it.

    SEE GALLERY: Vereeniging, a place of dirt and litter

    We, in the Vaal area are fortunate to have not one, but three rivers running through our town and suburbs. Anywhere else in the world that would be a major tourist attraction - but in Vereeniging it is a filthy, dirty area of ill repute.

    It's true, some people try to enjoy Vosloo Park in the summer months, especially the fisherman. They sit amongst the litter and broken bottles trying to enjoy some of the peace and tranquility it is supposed to convey. Cars roam all over what's left of the grass and the children have to play in the dirt. This used to be a park. A park where people could braai. You could not drive all over the place, you had to park and walk. Children could play on the swings and slides and one could walk dogs. How have we allowed our standards to drop so low that this shoddy excuse for a lifestyle has become acceptable?

    Three Rivers in Vereeniging shown below:

    In Vanderbijlpark, there are public parks, in Meyerton there are public parks, and in Johannnesburg you have Zoo Lake, the Botanical Gardens and the Zoo, to name a few places where one can sit and enjoy a picnic on the weekend.

    James hits 30 with the potential for much more - December 31, 2014 by Mr HomeBuilder

    The NBA's all-time scoring mark is well within his grasp.

    LeBron Jamesturns 30 years old today. Every birthdayis a time for reflection, but when the digit in the ten's place changes, it's more significant.

    James has accomplished quite a bit in his 11-plus seasons in the NBA: five trips to The Finals, two championships, three Olympic medals, four MVP awards, two Finals MVP awards and 37 triple-doubles.

    His 23,901 career points are more than any other player in NBA history has scored by the age of 30. It's enough to alreadyput him among the top 25 scorers of all time.

    Some notes on the list above ...

    Moses Malone (18,479) and Julius Erving (18,374) would rank eighth and ninth if we counted their points scored in the ABA.

    IfKevin Durantreturns from his current injury in the next couple of weeks and stays relatively healthy through the next 3 seasons, he could rank second on the list (at somewhere between 22,500 and 23,000 points) when he turns 30 in September of 2018.

    Only14 of the league's 59 MVP awardshave been won by players who had already reached their 30th birthday.Steve Nash(who turned 31 during the 2004-05 season and 32 in '05-06) is the only 30-plus guy to win the award in the last 15 years.

    Of the 64 times a player has scored at least 60 points in a game (like James did this past March), only five have come after that player's 30th birthday. Only twice in the last 45 years (since the days of Wilt Chamberlain) has a 30-plus player scored 60-plus: 30-year-old Tom Chambers in 1990 and 30-year-oldKobe Bryantin 2009.

    Asphalt shingle – Wikipedia, the free encyclopedia - December 30, 2014 by Mr HomeBuilder

    An asphalt shingle is a type of wall or roof shingle. They are one of the most widely used roofing covers in North America because they have a relatively inexpensive up-front cost and are fairly simple to install.

    Asphalt shingles are an American invention first used in 1901, in general use in parts of America by 1911 and by 1939 11 million squares of shingles were being produced.[1] The forerunner of these shingles was first developed in 1893 and called asphalt prepared roofing which was similar to asphalt roll roofing without the surface granules.[2] In 1897 slate granules were added to the surface to make the material more durable. Types of granules tested have included mica, oyster shells, slate, dolomite, fly-ash, silica and clay. In 1901 this material was first cut into strips for use as one-tab and multi-tab shingles.

    All shingles were organic at first with the base material, called felt, being primarily cotton rag until the 1920's when cotton rag became more expensive and alternative materials were used. Other organic materials used as the felt included wool, jute or manila, and wood pulp.[3] In 1926 the Asphalt Shingle and Research Institute with the National Bureau of Standards tested twenty two types of experimental felts and found no significant differences in performance. In the 1950's self sealing and manually applied adhesives began to be used to help prevent wind damage to shingle roofs. The design standard was for the self sealing strips of adhesive to be fully adhered after sixteen hours at 140 degrees Fahrenheit. Also in the 1950's testing on the use of 3/4 inch staples rather than roofing nails was carried out showing they could perform as well as nails but with six staples compared with four nails.[1] In 1960 fiberglass mat bases were introduced with limited success, the lighter more flexible shingles proved to be more susceptible to wind damage particularly at freezing temperatures. Also in the 1960's research into hail damage which was found to occur when hail reach a size larger than 1.5 inches.

    Asphalt Roofing Manufacturers Association (ARMA) formed the High Wind Task Force in 1990 to continue research to improve shingle wind resistance.[4]

    Two types of base materials are used to make asphalt shingles: A formerly-living organic base and fiberglass base. Both types are made in a similar manner with asphalt or modified-asphalt applied to one or both sides of the asphalt-saturated base, covered with slate, schist, quartz, vitrified brick, stone,[3] or ceramic granules and the back side treated with sand, talc or mica to prevent the shingles from sticking to each other before use. The top surface granules block ultra-violet light which causes the shingles to deteriorate, provides some physical protection of the asphalt and gives the shingles their color. Some shingles have copper or other materials added to the surface to help prevent algae growth.[5] Self-sealing strips are standard on shingles to help prevent the shingles from being blown off by high winds. This material is typically limestone or fly-ash-modified resins, or polymer-modified bitumen. American Society of Civil Engineers ASTM D7158 is the standard most United States residential building codes use as their wind resistance standard for most discontinuous, steep-slope roof coverings (including asphalt shingles) with the following class ratings: Class D Passed at basic wind speeds up to and including 90mph; Class G Passed at basic wind speeds up to and including 120mph; and Class H Passed at basic wind speeds up to and including 150mph. An additive known as styrene-butadiene-styrene (SBS), sometimes called modified or rubberized asphalt, is sometimes added to the asphalt mixture to make shingles more resistant to thermal cracking, as well as more resistant to damage from hail impacts. Some manufacturers use a fabric backing known as a "scrim" on the back side of shingles to make them more impact resistant. Most insurance companies offer discounts to homeowners for using Class 4 impact rated shingles.

    Organic shingles are made with a base mat of formerly living (organic) materials such as paper (waste paper), cellulose, wood fiber, or other materials saturated with asphalt to make it waterproof, then a top coating of adhesive asphalt is applied and ceramic granules are then embedded. Organic shingles contain around 40% more asphalt per square (100 sq ft.) than fiberglass shingles. The paper-based nature of "organic" shingles leaves them more prone to fire damage, and their highest FM rating for fire is class "B". Organic shingles are less brittle than fiberglass shingles in cold weather.

    The older organic (wood and paper pulp product) versions were very durable and hard to tear, an important property when considering wind uplift of shingles in heavy storms. Also, some organic shingles produced before the early 1980s may contain asbestos.

    Fiberglass shingles have a base layer of glass fiber reinforcing mat. The mat is made from wet, random-laid fiberglass bonded with urea-formaldehyde resin. The mat is then coated with asphalt which contains mineral fillers and makes the fiberglass shingle waterproof. Fiberglass shingles typically obtain a class "A" fire rating as the fiberglass mat resists fire better than organic/paper mats. Fiberglass reinforcement was devised as the replacement for asbestos paper reinforcement of roofing shingles and typically ranges from 1.8 to 2.3 pounds/square foot.

    Fiberglass shingles are slowly replacing organic felt shingles and by 1982 the production of fiberglass shingles overtook organic shingles. Widespread hurricane damage in Florida during the 1990's prompted the industry to adhere to a 1700-gram tear value on finished asphalt shingles[citation needed].

    Per 2003 International Building Code Sections 1507.2.1 and 1507.2.2, asphalt shingles shall only be used on roof slopes of two units vertical in 12 units horizontal (17% slope) or greater. Asphalt shingles shall be fastened to solidly sheathed decks.
