You are living in a zone of hefty rains and dense snowfall and that’s why you have this pitched or slanting roof above you. This is because you know that the best way to avoid ingress of precipitation is to drain it away as quickly as possible. What if you were shown that regardless of having these lofty slopes, your roof is inundated by snow dams and water ponds? And icing-on-the-cake is that the culprit is chimney, the stack which vents out hot smoke from your home. When would you require a chimney cricket on your roof? When the chimney of your house is located at downward slope of your roof and is more than 30 inches in width; it is likely to form a chimney roof valley. This valley if left unattended would allow the seeping water to accumulate. This accumulation is perilous for masonry of the chimney as well as for your roofing system. As this area is behind the chimney wall it is therefore least noticeable from the ground; because of this reason it is mostly overlooked by t

There is no denying how disheartening it is to see mold in your loft or attic and we recommend you to not succumbed by such infestation of spores. Inadequate and ineffective attic ventilation kick-starts the rotting process and this damage is not only stressful but it could also set you back many bucks in water-months each year. The fact of the matter is that whilst rampart mold development is being removed, a plan with unparalleled foresight to obviate and prevent it by efficient attic ventilation must not be ignored. While being in Portland or peripheral cities in states of North West, you are braced with moist climate and houses are therefore susceptible for an aggravated as well as repetitive attic mold development. So this read will guide you about the importance of roof top and attic ventilation and how it would affect over all life span of your roofing system.   Essentials of Roof & Attic Ventilation You might have already observed vented roofs and attics having a ri

Whether you’re thinking to refurbish and redecorate your house as a whole or a part of it, you might not know all the gamesmanship of renovation industry. All the first-timers out there, like you, must not readily jump into it without preliminaries. Because of ample decisive factors out there, peers are seeing renovation as a tough and tricky project. Your goal oriented investment could take you to next level of property ownership which otherwise could be a costly setback.         So keep reading because you would now be introduced to those common yet deadliest home renovation mistakes that have been collected from worthwhile experience of renovation consultants and interior designers. As a gift I would also explain some tricks that would save many bucks for you, guaranteed! 1.    Starting Project Too Soon So the day you bought a house and you think it is eyeing fussy without living in there for a day or two. This is the most common renovation mistake and a blunder that’s why I

Cracking moment equation is a famous formula that gives you the value of tensile bending stress at which the concrete of the beam starts to crack. This concept is important to understand the stress distribution of the beam across the depth. It will also help you to determine the deflection in the concrete at the point of failure. But for deflection calculation you can’t use the gross moment of Inertia (Ig) because of cracking effect. So, instead you have to use the effective moment of inertia (Ie) which provides transition between the upper and lower bounds of Ig and Icr.   However, for Ie you have to determine the Mcr which is the cracking moment. Establishing the Cracking moment Equation Let’s now derive its formula Step No. 1 – finding modulus of rupture But first you have to establish an equation for the modulus of rupture (MOR) of concrete. Modulus of rupture is the tensile flexural strength of the beam and it shows the amount of stress and force an unreinforced concrete

While looking for different types of concrete, you may be wondering about the foam concrete. It’s a relatively unique type of light weight concrete mix that has plethora of applications. Foam concrete is cement-based slurry that is made by mixing cement, water, fine aggregate and stable foam. The foaming agent agitates the air-bubbles into the concrete matrix and is thus also termed as aircrete, cellular concrete or low-density concrete. Foam Concrete – a non-toxic environmentally friendly alternative to standard concrete According to the Concrete Institute at Midrand, the foam concrete has minimum of 20% air to that of the concrete volume while the size of these bubbles can range from 0.2 to 0.4 mm. This agitating of air bubbles make this concrete resistant against fire and because of the same feature it processes highly flowability and excellent thermal insulation. Strength – It doesn’t matter always. Because its density ranges from 300 to 1800 kg/m3 (according to A Raj ),

Wondering about different types of bat bricks in construction and brick masonry? Well, with so many terminologies involved anyone can get confused. So, in today’s read we’d like to show you different types of cut bricks one may need while working on brick masonry. Please be noted that the word “bat” has nothing to do with your favorite hero character “bat man” J Bats in brick masonry The term “brick bat” is generally used to express a brick that has been cut along the width or length of the brick such that it is of smaller size than the original brick. Anyhow following are the different types of brick bats and their uses: The sequence of my below explanation will further help you in remembering the concept; so keep in mind this sequence as well. Closer The word “Closer” is given to such a brick bat that is used to close the brick course or in other terms that is used at the end of a course. In broader meanings, a brick is a closer brick when you cut it longitudinally and u
