When most construction professionals think of a ‘waterstop,’ they commonly refer to a ribbed profile extrusion of thermoplastic or rubber material. Waterstops are materials embedded in the concrete, with the purpose of blocking the passage of water through the joint.

To choose a waterstop that is suitable for your project’s waterproofing needs, it is vital to know the various product types and material compositions. Most varieties are manufactured exclusively for use in cast-in-place concrete construction joints, while some types can also be used with expansion joints. Moreover, there are some types of waterstops that must accommodate the expected lateral, transverse, and shear joint movements, as well as, the expected hydrostatic pressure.

Since the 1950s, the most commonly used waterstop is PVC (Polyvinyl Chloride). Due to its strong and flexible features, these materials have been used due to the ease of welding and inherent resistance to groundwater and common waste water treatment chemicals. There are now myriad of metal, plastic, asphaltic, and hydrophilic materials, with differing compositions that are utilized to stop water ingress through joints in concrete structures.

More About Waterstop PVC

In general, PVC waterstop acts as a continuous watertight diaphragm to prevent any flow of liquids in constructions joints which are subject to hydrostatic pressure. These materials are designed for expansion or contraction joint. In addition to this, it can also accommodate lateral and transverse movements which make it capable to fit the moving joints.

Furthermore, waterstop PVC are extruded from an elastomeric plastic material such as high-grade polyvinyl chloride, special resin and some chemical additives including plasticizers and stabilizers. The high material makes PVC waterstops unsurpassed with a variety of features and benefits as shown follow.

Features & benefits of Waterstops:

High tensile strength.

Superior elongation capacity

Supreme inherent elasticity and durability

High resistance to acids, ozone, seawater even diesel oil

Not vulnerable to fatigue deterioration unlike metal or rubber

Never discolor concrete

No electrolytic action with surrounding metals

Capable to withstand hydrostatic pressure

Combat the expansion and shrinkage movement of the joints

Capable to taking care of any deflection caused by the change in temperature

Supplied in coils for easy handling with high flexibility

Easy to install by tethering the outer flanges of the PVC waterstop to adjacent a reinforcing bars

Construction chemicals manufacturers always say that it is important that the waterstop is manufactured with quality raw materials, without defects. Many material types and profiles are available for different applications and conditions so the specifier should choose waterstops, preferably with manufacturer consultation, appropriate for all the joint conditions.

Are you looking for the right pvc waterstop for your project? At Corrotech Construction Chemicals, they offer various types of waterstops that help you create crack-free watertight concrete structures.

What is Waterproofing?

Waterproofing is basically the application of a layer of impervious material that prevents water from penetrating. This process makes the structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water.

Where Waterproofing is required?

Waterproofing solutions in building concrete structures are highly suggested at various locations such as the basement of the building, kitchen, toilet, and bathroom, balcony areas, roof, terrace, podium, swimming pool, water tank, etc.

What are the materials used in Waterproofing?

The most commonly used materials for waterproofing in building structures include cementitious material, bituminous material, liquid waterproofing membrane, and polyurethane liquid membrane, etc. Now, depending on your construction project and the needs of waterproofing itself, there can be various types of waterproofing method:

Cementitious Waterproofing Method

This is the easiest method of waterproofing in construction. The materials for the cementitious waterproofing method is easily available from construction chemicals suppliers of masonry products, and they are easy to mix and apply. This waterproofing method is commonly being used in various types of structures such as water treatment plants, sewage treatment plants, bridges, dams, railway systems, tunnels, and marine cargo ports.

Polyurethane Liquid Membrane Method

Polyurethane Liquid Membrane waterproofing method is very flexible and should be carefully applied to avoid peeling after some time. This type of method is commonly used for the roof, terrace and other areas that are exposed to weathering.

Liquid Membrane Waterproofing Method

Liquid membrane is a thin coating that consists of a primer coat and two coats of top coats which are applied by spray, roller, or trowel. The liquid cures into a rubbery coating on the wall. Moreover, the elongation properties of the coating that a liquid membrane offers can up to 280%.

Bituminous Coating Waterproofing Method

This type of waterproofing method is typically used for a flexible protective coat in accordance with its formulation and polymerization grade. Construction chemicals manufacturers say that its flexibility and protection against water can be influenced by the polymer grade as well as reinforcement of fiber.

In conclusion, it is important to find the right contractor in order to determine which of the waterproofing method is most suitable for your applications. Together with an experienced person and the right waterproofing products in Dubai, you will surely have a successful application.

Concrete is defined as a composite material that consists essentially of a binding medium within which are embedded aggregates. Most of the time, it is a combination of fine aggregate and coarse aggregate.

Concrete admixtures improve the properties of concrete in construction with special requirements. Chemical admixtures such as concrete superplasticizers can provide a number of beneficial effects on the handling of consolidation of fresh concrete as well as on the performance of both hardened and fresh concrete. To be able to successfully achieve the desired results and in order to avoid unnecessary instances, there are some precautions to be taken into consideration.

Furthermore, chemical concrete admixtures are used to achieve the desired workability in case of a low water-cement ratio. These admixtures also help in setting time of concrete for long distance transportation.

The following are some of the most important purposes for which admixtures are used:

Improved workability without increasing water content or decrease water content at the same workability level.

Accelerated time of initial setting.

Decreases of prevent settlement.

Modify the rate or capacity for bleeding.

Reduce segregation.

Enhance pumpability.

Decrease the rate of slump loss.

Increase bond of concrete to steel reinforcement.

Increase bond between existing and new concrete.

Improve impact resistance and abrasion resistance.

Inhibit corrosion of embedded metal.

Produce colored concrete or mortar

When Concrete Admixtures are being used?

When properties cannot be made by varying the composition of the basic material.

To produce the desired effects more economically.

Unlikely to make a poor concrete better.

Not a substitute for good concrete practice.

The required dose must be carefully determined and administered

Selection of Concrete Admixtures

Concrete chemical admixtures should be selected as per the specifications and should be used as recommended by a professional manufacturer like Corrotech Construction Chemicals.

For large concrete construction projects, the quantity of the admixture to be used should be obtained from tests reports for concrete mixed with admixtures at various percentage admixtures use. Chemical manufacturers say that these tests are conducted to fully understand the behavior of admixtures on the desired quality and strength of concrete. Thus, the optimum quantity of admixtures can be selected for a specific application based on results.

It is highly important that concrete admixtures should, including the Corromix Admixtures range, be used judiciously according to specification and method of application. This is to avoid adverse effect on concrete properties at fresh and hardened state.

When you experience cracks in concrete, it is really challenging to restore it back to its initial condition. One great way to repair it is to inject a liquid resin, while covering the surface with paste. There are two varieties of resin made with either of epoxy or polyurethane. Both materials have pros and cons. The process of concrete repair is relatively easy but a lot of people are confused: which is a better resin, epoxy or polyurethane?

Epoxy Based Resins

Epoxy is obtainable in different forms and for multiple applications. Most of the epoxy resins have a longer drying time. However, using an epoxy-based resin will ensure that the product cures hard and bonds securely to the surface.

The Advantages of Epoxy Crack Injection

The tensile strength of cured epoxy is usually 7000 psi whereas the tensile strength of concrete is in the range of 300 – 700 psi; obviously, the bond strength of epoxy is much greater than that of the foundation wall. This makes the epoxy a good option for foundation wall structural crack repair.

When a crack is under tension, it usually opens up. Hence, a material that cannot withstand the tension will tear. Epoxy is the best material to use when a crack is under tension; but construction chemicals manufacturers say that a reinforced polyurethane crack injection will work just as well.

The low-pressure injection process used for an epoxy crack repair provides visual confirmation to the technician that the crack has been completely filled.

The curing time allows the epoxy to slowly feed within the crack, thereby filling all parts of even the finest cracks.

Polyurethane Based Products

Polyurethane crack repair products are less expensive, and easier to use because of the mixture through a tube and its application. During cases of cracks and spalls, or when you need to rebuild control joints, it is recommended to use polyurethane.

The Advantages of Polyurethane Crack Injection

Polyurethane can be used regardless of the condition of the crack and the weather. It does not matter if the crack is actively leaking, full of mud and/or mineral deposits, or if it is fine or wide.

Polyurethane repair products can involve a crack flushing process to clean out the crack prior to injection.

The chemical expansion of the polyurethane makes it very effective at filling voids within the concrete. These voids are commonly invisible when you look at the wall and are often associated with the porosity of the concrete.

The rapid curing of polyurethane is beneficial when a leaking crack is flooding the basement. This is an important attribute when water-stopping is urgently needed.

The best way to know the best concrete repair method is to consult with experienced professionals about your specific type of crack problem. The team at Corrotech Construction Chemicals can provide consultation and expertise on a wide variety of methods, including the use epoxy and polyurethane based products, to repair your concrete.

A vital phase in a successful industrial flooring installation is the right preparation of the concrete substrate before the application of the flooring system. The risk of an improperly prepared concrete substrate can manifest almost immediately after installation; while preparing a surface with the right profile can help to ensure an effective bond of the coatings to the substrate. This will result in extending a floor’s strength, durability and appearance.

Surface preparation includes the removal of damaged or deteriorated parts of the substrate concrete and previously applied coatings.  In addition to this,  construction chemical manufacturers say that surface cleanliness is highly important in concrete repairs, as any loose debris, dirt, grease, or other surface contaminants can act as bond breakers. Surface preparation can save time and money as well as substantially reducing the possibility of coating failure and costly repairs.

Important points to remember for surface preparation for concrete repair:

All existing coatings and other surface contamination should be removed.

Preparation may be carried out through scarification, brushing, abrasive blasting, shot-blasting, and flame cleaning.

After preparation, the surface must be sound, dry and according to the satisfaction of the engineer.

Surfaces should be relatively smooth for applying most liquid-applied membranes and other thin protective coatings.

Trowel grade materials can be used to cover minor imperfections of surfaces. However, liquid coatings do not have this capability.

The concrete surface should be kept moist for several hours to ensure saturation.

Slush must not be applied in case of using dry pack material.

Inappropriate concrete quality and architectural features will result in increased potential for long-term contact with water. This means that concrete structures often require waterproofing systems to prevent water leakage and penetration. In addition to this, concerns about strength, damage to finishes and furnishings and other environmental conditions have made the waterproofing a desirable feature to any concrete construction.

The most common phenomena affecting the durability of concrete foundations arise from the contact between concrete and surface water, sulphate salts or chloride ions. This may change the microstructure and chemical composition of concrete and/or promote the corrosion of reinforcement steel.

Successful waterproofing solutions of concrete foundations prevent the degradation of environmental and health conditions of building materials used in below ground storeys and extends the service life of concrete constructions.

WATERPROOFING PRODUCTS IN DUBAI FOR CONCRETE FOUNDATIONS

A wide range of materials can be used in waterproofing systems for concrete foundations.

Liquid-applied systems require a particularly thorough surface preparation and skilled workmanship to ensure a consistent minimum cover thickness. This is why they are not often used to waterproof buried concrete elements, where accessibility of back-filling is limited and extended service lives are required.

Most concrete construction waterproofing works require either bituminous or synthetic prefabricated membranes. High flexibility is required for detail work on complex concrete shapes such as footings, which require a lower bending radius. It also enables the factory welding of different panels, which decreases the risk of joint failure since the resulting large sheets can be folded for transport to the construction site. The sheets would otherwise be supplied in rolls.

Furthermore, punching resistance and stress cracking resistance are desirable because they prevent potential damage from mechanical action during installation on concrete casting.

Stress cracking is often the failure of a membrane at applied constant stress lower than its tensile strength and it can be caused by several factors. These factors include cyclic temperature variations, the presence of chemical agents, UV oxidation and, fatigue. Also, membranes should support high elongation at break, so that they can resist any potential cracking of concrete.

Moreover, sodium bentonite has also been used in a variety of formats as a waterproofing solution. Water ingestion causes sodium bentonite to swell to several times from its original volume which results in filling any crack in concrete elements.

As there are several kinds of waterproofing products in Dubai, each with its unique strengths and weaknesses, it is then highly important to know which of these products is most suitable for your type of application.
