Teras Su Yalıtımı | Terrace Waterproofing

Terrace waterproofing is very difficult as the surface is flat and water cannot flow in any direction and allows it to stay where it collects. This gives a greater opportunity to cause leakage. These flat surfaces require a sump or trough for water to collect before it passes through the drainpipe. All these factors combined require extensive waterproofing. Terrace waterproofing makes a house more weather resistant by paying attention to all the minute details. The wear and tear used to create a perfect terrace free from all dust and dirt is achieved by large terrace waterproofing. Our techniques ensure that there is no way for water to seep from the surface. It is an important factor as it is typically exposed to adverse weather conditions, precipitation and climatic changes. The terrace surface tends to accumulate rain that starts to seep in between the blocks over time. Over time, the deterioration of the surface will increase, causing a lot of damage. The climate and current conditions in which the waterproofing will be made directly affect the material and timing to be applied. The reasons and conditions to be considered before starting the waterproofing process on the terrace are as follows; If possible, the slab slope should be poured at the reinforced concrete stage. (To support the application of slope screed)

  • The waterproofing material and system should be selected in accordance with the climate of the place.
  • Sliding based waterproofing materials or bituminous membranes are used on terraces.
  • The system is selected according to whether the thermal insulation will be on the floor or under the floor.
  • The system section is created in consultation with a technical staff (architect or engineer).

In the realization of waterproofing systems for terraces, regardless of whether it is a new construction or a pre-existing situation, it is important to know how to evaluate and ultimately choose the waterproofing system best suited to the current situation. It is therefore necessary to achieve perfection by paying attention to every detail and in many cases representing the critical points where water leakage occurs which causes subsequent problems. The ideal system for terrace waterproofing offers an elastic and extremely durable waterproofing layer, while providing exceptional adhesion to the cement bond to be used to apply the floor. It will be simple to implement as components that are specially examined for processing details (such as wall-to-floor corners and channels). The technical documentation of these systems must comply with the regulations in force for the intended use.

Which Methods Are Used for Terrace Waterproofing

Modern waterproofing methods have changed the construction industry over the years. The massive increase in urbanization and the need for effective waterproofing methods have replaced the old traditional waterproofing processes with newly updated and more effective waterproofing solutions. For most waterproofing problems, a single waterproofing technique or chemical is not enough. Combinations of chemicals and techniques are required to completely waterproof a structure.

1. Acrylic Waterproofing Membrane Method

These liquid applied systems provide successful installation with the elongation properties, durability, flexibility, abrasion and chemical resistance of the coatings. The liquid waterproofing membrane provides optimum performance and, most importantly, longevity. Therefore, this waterproofing method is a time-saving process and there is no need to cover other jobs as applied in the morning becomes dry and strong by the afternoon. It saves a lot of labor cost and gives maximum quality results.

2. Bituminous Membrane Waterproofing Method

Bitumen is a mixture of dense, viscous, viscous organic liquids composed primarily of polycyclic aromatic hydrocarbons, naturally occurring or obtained by the distillation of crude oil. Bitumen, also known as asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It is widely used in construction thanks to its waterproofing properties. Bituminous membranes are excellent for waterproofing roofs, basements, underground structures, bridges and other structures. Bituminous liquid applied membranes are the perfect solution for seamless, fully adhered and secure systems. They are polymer modified bitumen emulsions that do not require torch or flame application. They are available as water-based or solvent-based coatings.

3. Polyurethane Liquid Membrane Waterproofing Method

High-performance, liquid-applied polyurethane waterproofing methods provide uninterrupted protection from foundation to roof. It offers a heavy-duty, abrasion-resistant waterproofing coating with a highly aesthetic surface, resistant to pool water and UV rays. With excellent strength and elasticity, it has no seams or seams and provides 100% adhesion to surfaces and protection to rigid foam insulation products.

Concrete Terrace Waterproofing

When you waterproof concrete, masonry and other cementitious materials, you extend the life and durability of the structure. Whether you’re protecting a cinder block wall, concrete patio floor or poured concrete walls, keeping water out of concrete is a great step towards longer life. If you have masonry, concrete patios or block walls, waterproofing these structures is required by building codes. A high water table, a flood-prone construction site, or high rain levels dictate such waterproofing codes. In high-rise buildings, all substructures must be waterproof. Water Breaks Concrete; Not only does it look bad, it also weakens. You’ve probably seen surface damage on pavement or old grout. Concrete wears out, exposing the formwork materials and foundation concrete. In extreme cases, water will quickly destroy concrete, but it usually takes several years for it to start showing. If you damage the surface of the concrete, the underlying structure of your wall or floor will also be damaged. If you want to preserve the strength and fresh look of a concrete project, you need to waterproof it. When you waterproof the concrete, you also protect the rebar in the concrete against rusting and wear. Sealing your concrete floors requires a high quality, waterproof sealant that can withstand weather fluctuations and wet conditions. If you don’t seal your patio or balcony floor, you may find cracks develop. This is due to excessive moisture damage to the concrete. This can then lead to additional damage such as etching and annoying cracks.

Beton Neden Çatlar?

Concrete is an extremely porous material. It tends to absorb water and moisture into its core. However, this does not cause serious problems until you begin to notice its effects on the surface. This is particularly worrying during the winter months or in countries with heavy weather conditions. Ice, rain and snow can damage your balconies and terraces. This weakens the structure of the concrete and encourages cracks of all sizes to develop on the surface. If left untreated, these cracks can progress and grow over time.

Best Waterproofing Options for Concrete Terrace

1. Elastomeric Coating

Elastomeric coatings are a safe, durable and attractive way to protect and cover your concrete structure. They are applied in the same way as painting and priming. To paint on concrete you will need a suitable exterior primer and then the polymer paint will be applied on top. Two coats should be more than enough, and acrylic paint will also take care of gaps, small cracks and slight irregularities in the surface. Elastomer is a product with elastic properties and will therefore reshape itself according to the structure to which it is applied. This leaves an airtight and watertight surface to protect concrete buildings for years, regardless of temperature.

2. Silicone Sealant

Silicones can be used effectively to protect and waterproof concrete. Silicone also acts as a crack filler and sealant that can be applied to cracks up to 1 cm thick. Silicone or polyurethane sealant will work very well as a resurfacing to concrete structures that have already been preserved. The sealant can be applied using a spray method or with a regular roller.

3. Membrane Waterproofing

A liquid membrane protector is applied over the concrete structure to insulate the concrete from the weather. It has flexible properties that form impermeable layers on concrete to ensure sealing from external conditions.

4. Crystallized Waterproofing

Crystal sealants work on a catalytic reaction that seals cracks, holes and minor irregularities in concrete. It also closes capillaries and pores in concrete and penetrates into it to help seal naturally occurring cracks in concrete structures. Quartz sand is used in this method, along with chemicals suitable for waterproofing and sealing compound cement and concrete, to create a durable and robustly protected concrete surface.

Beton Teras Su YalıtımıWhat to Do Before Terrace Waterproofing

In order to make the terrace waterproof, first of all, it is necessary to evaluate the current conditions of the area to be intervened. Because there are different solutions depending on the protection status of the terrace to be intervened. There are different steps that need to be followed to be followed or to make a new waterproofing system. The first thing to evaluate is the condition of the existing flooring. That is, it is the visible layer that is easiest to investigate regarding the conservation status. This assessment can be made, for example, by checking that joint volumes are consistent. Because in most cases it is due to the joints where water starts to leak and therefore the finish has no waterproofing effect. As a result, the water will start to spoil the whole package with the elements seriously damaged. In parallel with this, it is possible to check the condition of the flooring elements. In fact, even if they are for waterproofing, any cracks or breaks that are the same give access to water that creates seepage points.

Steps to Waterproof the Terrace

First of all, it is necessary to distinguish whether it is necessary to waterproof again or we are talking about the restoration of an already existing terrace waterproofing system. This assessment allows us to understand at what level of the waterproofing package we need to intervene. In the first case, the implementation of the waterproofing system is simpler, while in the case of reconstruction, first of all, it is necessary to proceed with the analysis of the current situation. In the latter case, it is possible to perform an operative method that provides minimal treatment, which involves initially removing previous treatments such as any efflorescence or deposits, and then cleaning the support with a neutral detergent. After drying, the terrace can be re-grouted with a suitable external putty. It will therefore have excellent sealing properties that will ensure the integrity of the finishing layer and, consequently, its reconstructed integrity. In conclusion, to ensure that waterproofing is restored after the intervention, we will proceed with some processes that are in most cases transparent and film-free, providing waterproofing especially for risky spots such as the largest joints: the final layer of the terrace. From the moment we are sure that water has penetrated into the finishing layer, we proceed to restore the waterproofing of the terrace in another way. That is, to remove the existing floor covering that is irreparably damaged, together with the glue layer and the waterproof layer. This protects the screed. From here we will present a new waterproofing of the screed and subsequent bonding of the new coating with water-resistant liquid products, a cementitious adhesive suitable for the type of substrate and a mortar with waterproofing properties specially designed for outdoor use.

How to Prevent Leaks on the Terrace

Depending on the type of flooring desired to be applied to the terrace, care must always be taken to select the correct size of the joints and the material that composes them. For example, floors with large tiles were used more and more often. Therefore, the joints must be proportional to it. Thus, friction does not create subsequent cracks in the flooring and does not create risks of leakage. Another factor to consider is the thresholds. In other words, the connection between the balcony or terrace and the window door that connects it inside the house; For aesthetic reasons, it is a good rule that the terrace is at least 2.5 cm higher than the walkway, even if it is built at the same level of the floor. Therefore, the rainwater disposal function is only given to the slope. For the treatment of details such as wall floor corners, expansion joints or drains, special prefabricated elements are often created for use in the various proposed waterproofing systems. These can be butyl tapes, gauze or strips that provide additional waterproofing. Due to their particular geometric complexity, attention should be paid to points where the risk of leakage is always greater.

Well Insulated Terrace Business Example

The steps to be followed for the best waterproofing of a terrace can be summarized in the following steps.

  • Waterproofing of the terrace structure with appropriate vertical folds on the walls and protection of the sills.
  • Insertion of a layer of material that protects the waterproofing from the influence of the load distribution layer.
  • Creation of load distribution layer.
  • Application of a waterproofing system to protect the screed, which is then compatible with tile adhesives.
  • Setting the coating using an adhesive suitable for this purpose.
  • Grouting the joints of the tile coating with a suitable waterproofing mortar to prevent leakage from the joints.
  • Possible finishes to provide another waterproof finish.
