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.
