Since historical times people have widely used bentonite clay for waterproofing their houses. It was often utilized to the foundations of castles, fortresses, palaces and other historical buildings. Over time researches and development of bentonite clays have put them to the highest level. Nowadays bentonite waterproofing is a guarantee of functional durability of your house. Moreover, bentonite waterproofing is the real economic system – not only of your labor, but in addition your time and your money. It is simple to install and really effective. The process doesn’t require any additional skills, so you possibly can easily perform it with your own hands.
What’s bentonite waterproofing?
Bentonite pellets are at the core of this insulating material. It is natural material which is capable of polymerization. Sodium bentonite, with its particular structural features, tends to swell growing in volume 14-sixteen times. Bentonite turns into gel-like substance that fills the cracks and pores of the fabric of construction. After it gets a solid plastic material forms, the water-proof insulation layer appears.
To perform bentonite waterproofing in modern development process a number of species of waterproof materials is often used. They are divided into 4 foremost categories according to the method of performing:
surface waterproofing which is made normally made of asphalt and cement-primarily based supplies;
bentonite waterproofing membrane supplies which are introduced by roll-type supplies;
polymeric membrane supplies which are roll-mounted,
bentonite mats(or panels).
The principle advantages of bentonite waterproofing:
its high impervious properties;
the possibility to make use of these supplies in difficult conditions of waterproofing (they’re able to withstand hydrostatic pressure up to seven levels of atm);
because of its significant improve during hydration in a confined house it has the so-called “self-healing” quality;
the durability of waterproofing supplies which is due to its fixed properties over the time;
it is very simple to perform without requiring any additional skills (compared with traditional technology the hassle in this case is only 20%).
It is necessary to reiterate that the usage of bentonite waterproofing fills even the pores, cracks and voids which can be invisible to your eye, achieving an absolute indicator of water resistance – it certainly can give your house something that is very close to the time period “eternal life”
Nowadays among the most advanced modern supplies are bentonite mats. In the present day they’re often used within the construction to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they’re used within the development of hydraulic structures and underground buildings of varied types and purposes. Bentonite mats are a web-looking materials which consists of 2 layers of both non-woven and woven geotextile fabric linked in a needle-punched manner. Between them there’s crucial part of the waterproofing which is called the natural sodium bentonite (the injection way). It is layered as a number of rather thin sheets.
When utilizing bentonite mats consultants determine the following benefits:
the waterproofing work might be performed during any season of the yr;
simplicity of the system;
during the work it can repair itself eliminating minor mechanical damage arising throughout set up and backfilling of the pit, as well as quite a lot of cracks in the structure to be isolated;
ability to withstand the unlimited number of freeze/thaw cycles and dehydration/hydration cycles;
effort saving;
time saving;
low water permeability;
virtually a hundred% ecological purity;
durability and permanence of properties over the time;
the ability of “self-healing”;
resistance to varied chemical contaminants;
it can be utilized in complicated hydrogeological conditions;
it can withstand hydrostatic pressure of up to seven levels of atm;
resistance to aggressive environments;
it has a high adaptability, ease of installation in all weather conditions.
