The general basis for the selection of insulating materials, which are divided into the following main factors: Thermal insulation is not affected by chemicals or components found in sand or cement, because it is a non-chemical product that is very safe for humans and the environment and will not be affected by heat. It is highly resistant against combustion and is non-toxic. Where it has been proven that hospitals and children's schools affect the use of chemical insulation layers on surfaces

All roofs take a hit all year round from the impact of all weather conditions such as solar radiation, rains, hail, wind whilst the main cause of roof damage being the ultraviolet rays. These climate effects lead to roof degradation which entails; cracks in screed & corrosion of metal roofs, mold build up, screws popping out, thermal shock (expansion and contraction), concrete cracks resulting in the deterioration of its structural integrity, water and moisture leakage. This will result in high costs in

quid waterproofing membranes: advantages and preliminary considerations

19/12/2016

Construction defects, existence of critical points for waterproofing or wear resulting from rain or snow are often the cause of leaks in roofs and terraces. Without proper treatment, it is only a matter of time before leaks or moisture end up affecting the interior of our homes. As we pointed out in a previous article, there are numerous roof waterproofing systems on the market, but one is prevailing due to its versatility and quality/price value. We're speaking of liquid waterproofing membranes. What is behind this innovative product?

Liquid waterproofing membranes are applied like paint, upon drying, they form an elastic membrane with excellent waterproofing capability. Manufacturers of waterproofing solutions have developed several of these membranes from numerous compounds such as cement, silicone resins, acrylic copolymers, polyurethanes or bituminous and asphalt waterproofing agents.

However, which would be the most suitable for each application? Prior to selecting one solution or another, one must consider that not all liquid membranes are suitable for all surfaces; nor are all membranes suitable for all roof uses.

What must I consider prior to selecting a liquid membrane solution?

Transitability: for roofs subject to the passage of persons, liquid waterproofing with high resistance to pedestrian traffic would be applied,

Selection of suitable primer for each surface.

Level of protection of the system. Many systems may consist of heavy protective layers as well as finish layers that prevent separation from the support and protect it from environmental agents and mechanical damage.

Compatibility of materials: The technical characteristics of the membrane must be taken into consideration in order to ensure that it will support the weight of the covering. The materials must be compatible. For example, tile may not be used to cover a liquid membrane if it is not resistant to cement alkalis, as it would degrade and eventually destroy it. In addition to this factor, during application of the system, damage to the membrane must be prevented when applying the covering. This could occur when applying mortar with a trowel, if the liquid membrane is cut.

Insulation capability. The insulating properties of liquid waterproofing membranes are not features of their composition; i.e. they do not depend on whether they are acrylic, polyurethane or any other component. In and of themselves, these compounds have no significant insulating properties. This potential advantage depends on the pigment technology associated with colours.

Application requirements: Another fundamental aspect is to understand the circumstances under which application of each membrane is not recommendable. For example, frequently, there are limitations due to low temperatures. Additionally, application on surfaces with extreme insolation can be critical.

Primary advantages of liquid waterproofing membranes

Easy application:

High elasticity. .

Long useful life: Waterproofing properties extend over time without decreasing their effectiveness.

The Blatem Elastem System

As a result of decades of experience in the field of rehabilitation and waterproofing, Pinturas Blatem has developed its own unique system based on the advantageous properties of liquid membranes: the Elastem system. This solution offers waterproofing treatment, which also provides thermal-reflective properties for roofs and any exterior surface, reducing the transmission of heat into the interior of the house. Elastem is very versatile and is designed for application on concrete, mortar, fibre cement, terrazzo, bituminous, asphalt, metal (iron, galvanized steel or iron, aluminium), etc.

Composed of special acrylic copolymers, Elastem provides a smooth semi-gloss appearance and is available in white, red, grey, green and terracotta. Additionally, the system incorporates a geotextile reinforcement mesh manufactured using 100% high tenacity polypropylene staple fibres. This enables separation of the liquid membrane from its covering, as well as protection of the membrane from mechanical damage, puncture or abrasion.

Reinforce system with the latest technology

Beyond waterproofing, whenever additional characteristics are required, such as a walkable surface (transitability

The distinctive feature of the Elastem 180 mesh from Blatem is that the mesh to use is specific for this system. It may not always be possible to select any type of mesh, such as fibreglass, which is generally the most available. The mesh offered with the Blatem Elastem system has been tested jointly with the liquid waterproofing, so that they work together while providing optimal technical characteristics. In short, this is a liquid waterproofing system, and not simply a liquid membrane incorporating any reinforcement mesh with uncertain results

.

•Water absorption can be decreased.

•Prevents the formation of cracks on the concrete floor.

•The appliance is easy.

•It will increase the lifetime of a solid construction.

•It prevents corrosion of reinforcement.

•Also, prevents dampness inside the building.

•It prevents seepages from the ceiling and walls.

•This reduces the maintenance coast of the building.

•The property value can be increased.

•It supplies a healthy environment, good waterproofing system helps in making a clear living workspace.

•It protects the property as well as the people present therein.

Disadvantages of Waterproofing:

•Bitumen-based products soften in the summer heat because the black color has restricted life due to solvent evaporation.

•The polyurethane protective coating shouldn’t be very versatile.

•Polyurethane protective coating delays the natural breathing capability of concrete.

•The polyurethane protective coating has a restricted pot life, the impermeable floor coating permits water to form below the floor coating.

•Cementation waterproofing is the inability to maintain the cracks, which causes further leakage.

Advantages of waterproofing:

Variety of options

Depending on the level of water damage or owner preference, waterproofing systems can be installed indoors or outdoors.There are also DIY (Do it yourself) options available if you don’t want to spent extra for hiring a contractor.

Property value

Waterproofing increases your house’s value, which is the biggest advantage. This system prevents unwanted moisture from seeping into your walls, thereby allowing mold to grow. Mold can impact our health in a negative way. It also prevents damage caused due to water seepage which can ruin the structural integrity of your home. Moisture also causes metals to rust and wood to decay.

Durability of concrete may be defined as the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. Different concretes require different degrees of durability depending on the exposure environment and properties desired. For example, concrete exposed to tidal seawater will have different requirements than an indoor concrete floor.

actors Related to Concrete Durability

High Humidity and Rain: With little to no organic content, concrete is resistant to deterioration due to rot or rusting by in hot,humid climates if not covered by impermeable membranes.

Weather Resistance

When it has a proper system of microscopic air bubbles, obtained through the addition of an air entraining admixture and thorough mixing, concrete is highly resistant to freezing and thawing.

Chemical Resistance

Chemical Resistance: Concrete is resistant to most natural environments and many chemicals. Concrete is regularly used for the construction of waste water transportation and treatment facilities because of its ability to resist corrosion caused by the highly aggressive contaminants in the wastewater stream as well as the chemicals added to treat these waste products.

However, concrete is sometimes exposed to substances that can attack and cause deterioration. Concrete in chemical manufacturing and storage facilities is especially prone to chemical attack. The effect of sulfates and chlorides is discussed below.

Resistance to Sulfate Attack: High amounts of sulfates in soil or water can attack and destroy a concrete that is not properly designed. Sulfates (for example calcium sulfate, sodium sulfate, and magnesium sulfate) can attack concrete by reacting with hydrated compounds in the hardened cement paste. These reactions can induce sufficient pressure to slowly cause disintegration of the concrete.

What is alkali-silica reactivity (ASR)?

Alkali-silica reactivity is an expansive reaction between reactive forms of silica in aggregates and potassium and sodium alkalis, mostly from cement, but also from aggregates, pozzolans, admixtures and mixing water. , thereby inducing pressure, expansion and cracking of the aggregate and surrounding paste. This often results in map-pattern cracks, sometimes referred to as alligator pattern cracking. ASR can be avoided through 1) proper aggregate selection, 2) use of blended cements, 3) use of proper pozzolanic materials and 4) contaminant-free mixing water.

How do you protect a concrete surface from aggressive materials like acids?

   there are some aggressive materials, such as most acids, that can have a deteriorating effect on concrete. , A large number of chemical formulations are available as sealers and coatings to protect concrete from a variety of environments; detailed recommendations should be requested from manufacturers, formulators or material suppliers.

•Why does concrete crack?

Concrete, like all other materials, will slightly change in volume when it dries out. In typical concrete this change amounts to about 500 millionths. Translated into dimensions-this is about 1/16 of an inch in 10 feet. The reason that contractors put joints in concrete pavements and floors is to allow the concrete to crack in a neat, straight line at the joint when the volume of the concrete changes due to shrinkage

What are recommended mix proportions for good concrete?

Good concrete can be obtained by using a wide variety of mix proportions if proper mix design procedures are used. A good general rule to use is the rule of 6's:

•A minimum cement content of six bags per cubic yard of concrete,

•A maximum water content of 6 gallons per bag of cement,

•A curing period (keeping concrete moist) a minimum of six days, and

•An air content of 6 percent (if concrete will be subject to freezing and thawing).

reported that the possible reason for early corrosion in Florida bridges was the combination of the highly aggressive environment (such as heat–cooling cycle, UV exposure), highly permeable concrete and flaws and damage to FBE coating.11The scenario could be worse in many parts of the world with poor handling practices and high UV indices.

Seal Flexi proof is a two components elastomeric acrylic modified cementitious waterproofing coating which is applied on concrete, masonry and most other surfaces. Seal Flexi proof is a standalone product that can be left as a finished surface or coated with mortars, paint, etc.. Seal Flexi proof can be applied to new and old substrates to provide a protective, waterproof coating.
