Why Roll Waterproofing is Complex?

Written by adminAugust 24, 2022

Roll waterproofing is a complex work on the installation of a waterproof coating. It mainly isolates underground parts and buildings’ roofs from groundwater penetration or precipitation. Works are carried out with sheet material rolled into rolls. Therefore, this type of waterproofing received such a name. This is the most popular type of external protection and has a wide application around the world.

Top general contractors NYC With a professional approach to the choice of materials and quality work, the service life reaches 20+ years.

Which roll material is better?

Roll insulation is a waterproof sheet designed to protect against water penetration. It consists of a supporting base, which is coated on both sides with a binder and has several mounting methods.

Designed for waterproofing:

roofs
foundations
basement walls
overlapping
pools
main pipelines
bridges
underground structures

There are many manufacturers and options for commercial waterproofing services. The choice should be based on site-specific conditions and requirements for long-term protection against water intrusion.

The main characteristics of roll waterproofing:

without base, roofing felt, programming (roofing cardboard), fiberglass, fiberglass, or polyester.
The composition of the waterproofing (binder) substance. Can be: bitumen, bitumen-polymer, polymer.
Mounting method. They can be: glued on special mastics, welded by heating, and self-adhesive.
The presence of surface dressing refers to bitumen and bitumen-polymer. Depending on the purpose, they are distinguished without sprinkling: coarse-grained, medium-grained, fine-grained, pulverized, or scaly.

If we compare all the options for roll coatings in terms of quality, durability, and cost, we get the following rating:

The lowest place is occupied by products based on the roofing material, roofing felt, glassine, and bituminous binders. Low price. Poor quality, water resistance period: 1-3 years.
The most popular category is based on fiberglass, with a bitumen-polymer composition of insulating substances. Low-mid price category. The average level of quality and the period of water resistance of the material is 7-10 years.
The most expensive category, among bitumen-polymer, coatings based on polyester. As a rule, it is produced with an excellent bitumen-polymer composition of insulating substances. Medium-high price category. Medium-high quality level, water resistance period 10-25 years.
The benchmark for durability is polymer roll coatings – PVC membrane. This is roll-sheet insulation; installation is carried out on special fasteners. The sheets are soldered with hot air, forming a very reliable solid sheet. High price category. High level of quality, water resistance up to 40 years.

Roll products on bituminous binders, without polymers, and on an organic basis: roofing felt, parchment, and roofing felt are of poor quality. These are unreliable materials as they decompose in the ground if used below the surface. When used on the roof, they melt in the sun, tan in frost, and quickly lose their waterproof properties. But a significant plus is the low price. We do not recommend using this category of materials as they will not provide long-term waterproofing.

The category of insulation is entirely polymer-based, very reliable, and durable. Technologically, it is allowed to work in the rain and with a damp mounting surface. It is essential to use high-quality materials and responsibly perform work. In this case, it is enough to use one layer of PVC membrane to insulate the roof. Therefore, despite the high cost per m2 of PVC materials, the cost of work and materials is comparable to the use of bitumen-polymer. But, if everything is done correctly, you can significantly win the quality of the resulting roofing.

Among bitumen-polymer, polyester-based materials will be the best choice in terms of durability. This type has an increased elasticity of the canvas, and it can stretch. Due to this, the thermal expansion of the building and roof is compensated, and the seams retain their tightness for a long time. The price is higher than the material of fiberglass and fiberglass.

We recommend using materials from the category of bitumen-polymer material based on fiberglass. This is the most widely used rolled waterproofing. In case of increased water tightness and service life requirements, we recommend using a PVC membrane. This is the most durable technology.

Which mounting technology to choose?

There are two primary installation methods for the bituminous rolled products: pasting and fusing. The self-adhesive method is rarely used, for example, when it is necessary to work indoors or when laying on combustible surfaces.

Regardless of whether the application surface is vertical or horizontal, deposition technology is predominantly used. This is a more reliable technology for waterproofing Contractors NYC. It is explained by the fact that it repeats the curves of the surface with greater accuracy, and the uniformity of the binders provides a firmer grip in contrast to the gluing technology, which uses an intermediate layer in the form of bituminous glue (mastic). Also, the built-up installation method is faster, which allows you to offer a lower cost for work.

Self-adhesive roll coatings are more expensive; their installation requires more time than fusing technology. This installation method has lower adhesion to the surface, which leads to a loss of laying quality on vertical surfaces. The application is recommended for flat roofs with small amounts of work.

Marking – instructions for use.

When purchasing materials, you need to know products’ labeling and decoding. These designations define the technology of waterproofing works and indicate distinctive features.

Marking example:

lining
roof installation NYC
fiberglass
Polyester.

Each marking corresponds to its purpose or conditions of use.

Roll coatings for waterproofing foundations and basements.

Roll insulation is considered a universally recognized means of protecting the foundation and basement from water penetration. But this waterproofing has a severe risk to its suitability in the environment of soils saturated with acids and alkalis!

Firstly, bitumen is an organic substance, and under the conditions of an active micro-organic environment of the soil, it is exposed to the aggressive action of bacteria and microorganisms. Secondly, when the material is exposed to the chemical composition of the soil, it loses its waterproofing properties. Therefore, you need to take the issue of choosing a roll coating for waterproofing the recessed parts of the house seriously. The materials must contain special polymeric modifiers, plasticizers, and antibacterial additives. Using such coatings, you can count on reliable and long-term waterproofing.

The technology of laying waterproofing in two layers :

Important:

Calculating the necessary material for the work is carried out with a margin. The amount should be 15-20% more than the coverage area. This is due to the need to overlap the insulation and the inevitable formation of scraps of material. Trimmings are not suitable for installation, the more, the more complex the work surface.

Algorithm and content of waterproofing works

Preparing the base for laying

The preparatory stage of work is as essential for a quality result as the process of installing waterproofing itself. This stage of work is the key to long-term and reliable protection against water leaks. Any significant irregularities, chips, cracks, or surface defects must be repaired using a cement-sand mixture. If necessary, preliminary jointing of defects is done with a perforator, and a fillet is made at the corners of perpendicular surfaces. The surface is thoroughly cleaned from sand, dust, and dirt.

Application of bituminous primer

The surface leveled from defects is treated with a bituminous primer, which is necessary to increase adhesion between the rolled material and the structure. It is applied with a roller in one layer. We are against the recommendation that diluted bitumen can be used instead of a primer. Poor-quality bitumen instead of a special primer can not only not help but also harm the quality of waterproofing work.

Overlapping

The laying of the roll material must be overlapped. Docking along: the first canvas, covered by the next one by 10 cm. Perpendicular joints (end): the first canvas, covered by the second by 15 cm of the canvas. The amount of overlap increases with the presence of a slope and the complexity of the surface to be covered. In these cases, the value can be 20 cm – 25 cm.

Fusion of the first layer (lining)

When working on horizontal surfaces, one person can easily handle it. When working with vertical, laying should be carried out in pairs. We also recommend working in pairs when laying horizontal surfaces, such as roofs. So having two people walking on the same weld roll will increase the downforce and give a stronger adhesion.

Work on underground waterproofing is a complex of various construction activities. The essence is to create reliable protection of reinforced concrete and concrete structures from the aggressive influence of seasonal and soil waters.

However, the waterproofing of underground structures is hampered by the complete absence of natural light and poor ventilation.

The list of problems that arise due to a violation of waterproofing is as follows:

Weakening the bearing capacity of the building;
Failures in the operation of underground communications;
Corrosive changes in reinforcing elements;
Breakage of power cables;
Increase in the cost of repairs, finishing works, and restoration of waterproof;
Problems with tenants, which can lead to litigation.

Types of Waterproofing

Protection of the building from moisture is carried out at the stage of construction work. This is due to the ability to have free access to the outer walls of all buried structures, up to the stage of filling them with soil.

Another important condition in work on creating high-quality waterproofing service of underground garages, basements, parking lots, and basements is the presence of a drainage system.

To prevent the destruction of reinforced concrete structures when exposed to water, the following types of waterproofing are used:

Primary waterproofing involves using concrete-based compounds or special mixtures with a high degree of resistance to moisture and low temperatures.
The secondary type of waterproof includes the process of applying a special protective layer to the treated surface using PVC membranes or “liquid rubber.” The advantages of this method include penetrating waterproofing, which helps prevent moisture from entering the open rooms and protects the building from the effects of soil water containing harmful salts and acids. But, to repair or restore underground waterproof, you should use the injection method of waterproofing since it is the most effective.

Waterproofing contractors NY by injection or buried parts of a building structure has many advantages, mainly the absence of earthworks. BLOCK, this, in turn, will allow the customer to save time and money because they need to use earth-moving equipment that will disappear by itself.

The injection method can be applied at any time of the year and is performed inside the room.

The company “Noah Builders NYC” provides waterproofing services for underground structures in NYC, including work on restoring waterproofing by injection.

Based on the hydrogeological conditions of the construction site’s location and based on its operational characteristics, the professional craftsmen of the company ” Noah Builders NYC” developed the most effective algorithms for the implementation and restoration of waterproofing.

The list of services provided by Noah builders includes:

low-pressure injection;
work on injection of cracks using construction packers;
hardening type injection;
work on injection of large premises;
Injection of seams in concrete.

The Noah Builders NYC company owns all the necessary equipment for injection work, which makes it possible to carry out all construction activities for high waterproofing underground structures with high quality, taking into account all the construction site features.

Waterproofing of Underground Structures

More often than other construction projects, underground structures are subject to the aggressive effects of high-pressure groundwater.

The following objects fall into the risk group:

Metro and underground tram stations
Underground car parks
Mines and bunkers
Buried fire tanks
Treatment facilities
Auto tunnels

The peculiarity of such buildings is that access to the outer sides of the structures is very difficult, and waterproofing work has to be carried out in conditions of constant water flow.

Only the technology of injection waterproofing contractors NY, which the specialists of our company widely use, can cope with such problems.

The injection method effectively fights soil water, even when water flows in a continuous gushing stream.

In this case, special polyurethane foam is used, increasing its volume several times in contact with water. At the next stage, injections are carried out with a polymerization composition, which blocks the moisture penetration channel for many years.

When waterproofing contractors NY buried objects, particular attention should be given to sealing seams, mates, and joints. If waterproofing restoration work is carried out at an average or low level of groundwater pressure, resins with a long setting time are used.

Waterproofing works of the underground part of the building. Any building structure has a recessed part – the foundation, which can be located at different depths, depending on the number of floors of the building, its type, soil features, groundwater level, and climatic conditions of the area.

As a rule, ancient building objects in NYC are erected on a foundation of stone or brick. However, voids and cracks may appear in the masonry of such materials of waterproofing over time. Such processes are also typical for concrete.

Professional craftsmen working in the company “Noah Builders NYC” can quickly restore waterproofing, organize reinforcing filling of voids, improve the bearing characteristics of the underground part of the construction site.

Our specialists are real professionals who have the necessary knowledge and experience to choose the most effective method. All this, combined with innovative waterproofing materials, provides a high level of moisture protection for brick or stone masonry and reinforced concrete structures.

Stage of Preparatory Work

The course of preparatory work directly depends on the chosen waterproofing technology.

At this stage, specialists mark the location of the packers. It is through the packers that the synthetic waterproofing material will be injected.

If, after examining the state of damage, it is decided to use a different type of waterproofing material, such as penetrating compounds or “liquid” rubber, then surface preparation will play an important role in achieving the optimum level of surface protection against moisture.

The preparatory work algorithm is aimed at ensuring:

Increasing the level of the bearing capacity of the structure;
Dryness and cleanliness (elimination of grease and other contaminants, as well as the old coating) of the structure;
strength;
Roughness, which provides adhesion to concrete.

Specialists of the Noah Builders Company perform all types of work to eliminate leaks, strengthen reinforced concrete structures, repair and waterproof underground parking lots, injection of monolithic reinforced concrete structures.

Many homeowners love to do their own roof repair, but you need to weigh the pros and cons before you tackle any repairs.

Roof repair and replacement is a complex and expensive type of work. Most homeowners don’t have the equipment to do the job, and most end up making expensive and dangerous rooftop mistakes.

Professionals Have The Knowledge And Experience.

Few homeowners realize that roofs are more than just a layer of shingles. The roof is a complex system with many different components and layers. These parts work together and must be properly connected to drain water from the roof and not into the house.

Professional roofers are trained to understand roofing systems and install their components by manufacturer’s standards and their local building code standards.

This knowledge gives professional roofers skills that you may not be aware of. For example, when a professional roofer finishes renovation work, they may notice other problems with your roof that you would not know.

When a professional works on your roof, they will consider the function of the roof and its aesthetics. After all, your roof is a key part of the visual appeal of your home.

It takes practice and skill to install a roof that looks good.

Liability And Insurance

Your home insurance probably won’t cover any damage you cause to your roof by walking on it or repairing it without the proper knowledge and skills.

Your insurance company may claim that your actions were negligent, in which case you will have to pay for the repairs out of your pocket.

Professional roofers are less likely to make mistakes. When they do, they usually have insurance to cover any damage.

By choosing a roofing professional, you get contractor insurance coverage and save yourself the hassle and expense of losing your insurance.

Material Manufacturer Warranty

Homeowners trying to fix a roof on their own often feel that their roof is covered by the manufacturer’s warranty. But, usually, it is canceled.

Manufacturers require their products to be installed correctly following their instructions for use and building code requirements to be eligible for a coverage guarantee.

Professional roofers are best suited to properly meet these requirements.

Aside from the risk that a homeowner’s roofing services NYC could void the warranty, poorly installed shingles can allow water to leak under the shingles, which can damage all other layers of the roof, let alone your home.

If you damage your roof while trying to repair it yourself, a professional will not restore the warranty coverage.

Costs And Tools

Many homeowners find it beneficial to do their own roof repair because they believe it will save them money. But, as a rule, this is not the case. A small mistake on your roof could end up costing a lot more in the future with additional damage.

Even if everything goes smoothly with your renovation job, it will probably cost more than a professional job. Few homeowners can accurately assess roofing work. Research shows that projects end up costing twice as much as homeowners think. This is in part because homeowners will have to buy a lot more materials than they need.

Shingles are a good example of this. If you only need five shingles to repair, you will have to buy a lot more per bundle of shingles. Alternatively, a professional roofer can take the rest of the shingles from this package and apply them to another roof. The same goes for nails, roofing cement, and other roofing materials.

Professional roofers also use tools that are expensive to buy or rent. You will have to rent an extension ladder, seat belts, and a safety helmet, and you will need training for working at heights before going up to the roof.

If you are trying to save money or time by not renting the proper equipment and not knowing safety precautions, you are at great risk to your health.

Time

Just as homeowners often underestimate the cost of projects, they also underestimate the time it takes to complete a project.

When you work on a roof, some are exposed to rain, wind, and snow. Even if you cover the roof with a tarp, the elements can damage your roof. It is important to complete roof work quickly and efficiently to reduce the risk of damage. You can’t leave her next weekend if you don’t finish in time. Weather conditions can change quickly, and even exposure to sunlight can damage some roofing materials.

A professional roofer gets his job done much faster than a homeowner, thereby reducing the impact of weather on the roof.

Danger To Life

Roofing is a dangerous job. The biggest risk is the likelihood of falling from a ladder or roof. Homeowners are more prone to injury while on stairs or rooftops as they lack preparation and often lack adequate safety equipment.

It is not safe to walk on the roof, especially if the roof needs repair. There is always the possibility of falling from a ladder or from a roof construction contractor. Many people visit the emergency room each year or die after falling downstairs.

Walking on the roof can also damage the roof. You may be stepping in the wrong place, wearing the wrong shoes, or walking too hard. For example, it is best to avoid walking in the roof valley, as this is one of the roof’s most vulnerable areas. If you’re not properly trained, rooftop walking can cause a bigger problem than the one you’re trying to fix.

If your roof has been damaged by water, it is even more dangerous to walk on it. Even small leaks on the roof can cause structural damage to the roof when the supports rot. This damage is especially likely if the leak has gone unnoticed for some time. When you step on an unsupported part of the roof, you can fall and be seriously injured. Such a fall will also damage your home.

Professional roofers are trained to see warning signs that the roof may be unsafe and have the appropriate safety equipment to catch them if the roof collapses.

Summing Up

It is generally wiser to hire a professional roofer rather than trying to fix the roof yourself. If you are trying to renovate your own roof, you risk damaging it and damaging the rest of your home. You can also void your warranty, and it will end up costing you much more than if you hired a professional roofer in the first place.

If you want to be more informed about what your roofer will be doing on your roof, you can always ask them questions. A reputable roofer will explain to you what damaged your roof and how he plans to fix it.
