Which of the following is a case that usually use blindside waterproofing?
A. when foundation wall are built on property line
B. when foundation is too deep and too wide
C. when foundation rests on saturated bedrock
D. when site is too steep
A. when foundation wall are built on property line
Blindside waterproofing is the application of waterproofing system before the foundation and foundation walls. The waterproofing membrane is applied to the soil support (i.e. shoring, sheet pile, slurry wall, rocks, neighboring building) and then concrete or shotcrete is applied against the membrane. This is usually done when there is no sufficient to the other side of the foundation wall.

Dampproofing
This construction method, is done where time is critical for the project. It is usually done for buildings with deep basements or underground structures. It is known as what?
Top-down
In a conventional bottom-up construction, the foundation and substructure are constructed first before the superstructure (building components above the ground). However, in cases where basement or substructure is too deep and may take up too much time, top-down method can be employed. In this method, the construction of the superstructure is done first before or simultaneously with the substructure. This way, construction time is significantly reduced.

Pile driving is a mthod used to drive piles into the soil, to provide foundation support for buildings and structures. What is the simplest material used as piles?
Timber
Pile may be made of wood, steel, concrete or various combinations. The simplest are timber piles, made from tree trucks with their branches and bark removed and driven into the ground small end first. Timber piles are are economical for lightly loaded foundations but cannot be spliced so only limited to the length of the trunk.
It is the development of a yellow cast in painted suraves usually when the coating used is oil-based. The alkyd or plant-based oil reacts with oxygen in the air and naturally turns yellow. — of oil-based paints overtime is considered natural.
Yellowing or “Paninilaw”
— can also be caused by the lack of natural or artificial lght source. When oil-based paints dry, it also forms yellow-colored molecules known as chromophores. These molecules breakdown when exposed to light. These molecules remain if not exposed to light. — is also more noticeable in white and off-white oil-based coatings.
Yellowing
Yellowing can also be caused by the lack of natural or artificial lght source. When oil-based paints dry, it also forms yellow-colored molecules known as —. These molecules breakdown when exposed to light. These molecules remain if not exposed to light.
Chromophores
It is a paint defect characterized by its rough appearance, particularly felt by hand. The main cause of this is contamination within or on the surface of the paint film. These unwanted objects include dirt, sand, grit or others.
This can be prevented by properly cleaning the surface before applying the paint. It is also important to clean the painting equipment and tools.
Bittiness
Is characterized by the appearance of undulating waves on the painted surface.
There can be several causes of his defect. One common cause is the use of too much paint creating a thicker paint film than required. The upper coat therefore dries faster than the bottom layer. Another cause can be the use of too much oil or painting in a high temperature environment. It is more noticeable in thicker coatings such as enamels and varnishes.
To prevent —, make sure to dry the first coating well beofre applying another layer. Also make sure to follow the specified painting method.
Wrinkling or “Pangungulubot”
Refers to the chemical reaction between oil and alkalis. This reaction produces a soap-like substance on the coated surface.
It is usually seen in new concrete or plastered surfaces which have high alkalinity, If oil paint is applied to the surface, there will be a hydrolic breakdown of ester bonds. This reaction creates a thin sopy substance on the paint surface affecting its durability and adhesion.
Proper surface cleaning and preparation is important to avoid —. Avoiding oil-based coatings on concrete is also advised.
Saopnification or “Pagkatas”
It is the appearance of pebbled or uneven surface, similar to an orange skin due to improper painting technique. It is seen in spray painted surfaces and high-gloss coatings.
Common causes include the quick evaporation of thinner, applying excessive paint or incorrect spraying setup and direction. In some instances, the top surface can be rubbed out and polished to remove the — effect.
Orange Peel
It is the failure of the paint coating to hide the color of the original surface. The underlying surface is observable through the paint due to its poor opacity.
It can be caused by applying coats that are thinner than required. Other causes include the use of unsuitable undercoat, excessive spreading or uneven paint application, The usual remedy is to paint over the surface to increase the paint film’s thickness and opacity.
Grinning
The loss if color of one or more of the color pigments within the paint film.
It is characterized by the lightening of the painted surface. Although fading of pain overtime is considered natural, it can be accelerated by environmental factors suuch as excessive sunlight exposure and thermal differences.
Other causes include over-tinting, contamination and improper application technique.
Darker paints and paints applied externally are more prone to fading.
Fading or “Pangungupas”
Cracking, crazing and alligatoring are all related to paint defects characterized by the random breaks or crevices in the paint film. It is the splitting of the paint film through at least one coat. This defect eventually leads to flaking and peeling. Note that there is no definite difference between the terms cracking, crazing and alligatoring. Crazing usually refers to shallow and smaller splits while alligatoring refers to the pattern formed by the cracks.
One possible cause is the internal stress to which the paint system cannot withstand such as movement and contraction of the substrate. It can also be caused by incompatibility of paints (i.e. using hard-drying coats over softer ones), improper surface preparation and inadequate mixing. If the crack extend through the whole thickness of the film, painting over it is no longer advisable. The filnm should be stripped.
Cracking and Crazing
— or running refers to the downward movement of paint that can appear shortly after the application and before the setting of the paint. It is also curtaining when it occurs over a long distance (like a curtain).
Possible causes of — include thicker application than the specified, excessive/improper thinner, improper mixing/spaying, or lack of curing agent.
If — is noticeable at the spraying or painting stage, it can be brushed out while wet. If it has dried, it can be abraded and repainted.
Sagging or “paghulas
Flaking or peeling is characterized by paint films lifting from is underlying surface in smooth small to large sections.
It is primarily caused by the loss of adhesion between the paint and the substrate. There are numerous reasons of flaking and peeling of paint films includeing improper surface preparation, presence of moisture, chemical attack and exposure to sunlighr and heat. Paints applied thinkly are also more susceptible to flaking and peeling.
This condition is usually a result of other paint defects.
Flaking or Peeling or “pagbibitak or pagtutuklap”
Considered as the mother of all painting problems, — refers to the crusty salt deposits formed on the surface of brickworkd, plasterwork and concrete masonry walls.
When warer and moisture pass through the concrete wall and evaporate, it leaves salt behind. These salt depositas crystallize beneath the paint film ruining the coating.
— can ve caused by water seepage, improper curing of the substrate and thermal diferences. If water and moisture unavoidably seeps through the wall, dampproofing the substrate before painting is a good solution.
Efflorescence or “umido”
— refers to mold and funguus that grow in warm, moist, starchy and acidic environment. Since it needs moisture to survive and thrive, it can be seen in moist places such as bathrooms, wash areas, kitchens and areas without proper ventilation.
The appearance of mildew in surfaces affect the integrity of paint acoting and irs bond with the substrate. It can also cause allergies and other negative health on the occupants.
— can be removed by applying — remover, bleach solution or other disinfectants.
Mildew or “amag”
It is the appearance if irregular bubble-like spots beneath or within a coating, lining or paint film. These — can be filled with air, liquid or even cystals.
— is largely due to the condition of the underlying surface when the paint was applied which causes improper adhesion of the coating to the substrate. Usual causes include insufficient cleaning and drying of the surface, contamination of paint tools and excessive moisture that may pass through walls.
— usually leads to peeling.
Blistering or “paglobo”
it refers to the fomation of a white, chalky powder on the surface of the paint film. This powder is the result of the designation of the binding agents or other components of the paint film.
There can be several causes of chalking in paint which includes excessive exposure to UV (sunlight), moisture and oxygen. Contaminants on the surface can also cause this.
Through chalking overtime is normal to many paint types, there are paints with more UV resistance that can be used to prevent — and fading. It can be used to repaint — painted surfaces.
Chalking or “pamumulbos”
This paint defect is usually characterized by a spot-like discoloratiion of the top coat.
The discoloration results from leaching out or diffusion of the soluble substance rom the substrate into and through a freshly applied paint or varnish coating.
On ecommon example of this paint defect happens when paint coating is applied in wood without proper surface preparation. This is caused by tannic acid or tannis present in some wood. These substances can bleed through coatings if not properly isolated or sealed.
Bleeding can also happen when incompatible paints are used.
Bleeding
— is a paint defect characterized by a milky white haze or mist formed on the surface of the paint.
It is usually caused by moisture condesing on, and being trapped in the wet film. This can be due to humid or wet weather while applying the paint.
Blooming
refer to the difference of color and sheen in the paint film due to bad paint application or poor paint quality. It is primarily caused by rapid drying of the paint coat before another wer coat is applied.
To prevent this, the film edge should not dry before applying another coat. Fast drying of paint coats can happen when painting in direct sunlight or in an extremely hot temperature.
Proper paint brushing and rolling technique can help prevent tap marks.
Lap Marks or “Kabisada”
In painting works, which is the most common cause of grinning?
