2.4 : THERMAL, SOUND INSULATION AND MOISTURE PROTECTION

The Process of making an object or structure water resistant so that is remains relatively unaffected by water or resisting the ingress of water under specified conditions.

• Soundproofing

• Sound Insulation

• Damp-proofing

• Waterproofing

a type of moisture control applied to a building walls and floors to prevent moisture from passing into interior spaces

• Soundproofing

• Sound Insulation

• Damp-proofing

• Waterproofing

A kind of measurement to prevent the sound waves from permeating

• Soundproofing

• Sound Insulation

• Damp-proofing

• Waterproofing

means of reducing the sound pressure with respect to a specified sound source and receptor

• Soundproofing

• Sound Insulation

• Damp-proofing

• Thermal Insulation

Reduction of heat transfer between objects in thermal contact or in range of radiative influence

• Soundproofing

• Sound Insulation

• Damp-proofing

• Thermal Insulation

Which of the following is NOT a type of waterproofing?

• Torch Applied and integral Crystalline

• Roof Garden

• Elastomeric

• Cementitious

• Sprayed Polyurethane Foam

Mostly surface applied, its solution are mainly surface coating with little penetration capabilities. Water absorption is effectively reduced by promoting beading effect.

• Hydrophobic Materials

• Hydrophilic Materials

• None of the above

its technology actually uses water and turns into microscopic crystals using a chemical reaction. the crystals increase in number and length to densify and seal concrete pores and voids.

• Hydrophobic Materials

• Hydrophilic Materials

• None of the above

made of sticky viscous organic liquids and bitumen, essentially its a hydrocarbon made from crude oil.

typically used on flat roofs and decks , balcony's, planter boxes and below ground.

• Torch applied waterproofing

• Sprayed polyurethane foam

• Cementitious waterproofing

• Elastomeric

Answer explanation

Types of membrane used:

1-APP (Atactic Polypropylene Plastic) - melts well when heated, provides heat and UV resistance

2- SBS (Styrene Butadiene Styrene)- rubber modified asphalt not appropriate for applications where UV exposure is anticipated

waterproofing method for concrete that uses cement based polymer coatings

• Torch applied waterproofing

• Sprayed polyurethane foam

• Cementitious waterproofing

• Elastomeric

Answer explanation

Cementitious coating can be divided into 2 types:

1) Crystalline cementitious waterproofing: it is included in the wet concrete before pouring, provides waterproofing in its own matrix, can also be sprinkled.

2) Flexible Cementitious waterproofing - aka Polymer-modified cementitious waterproofing

powder component is mixed with its liquid binder, when properly combined it can be brushed, trowel or sprayed

-e.g. plexibond boysen, powermix boxtik. etc.
