Since historical occasions folks have widely used bentonite clay for waterproofing their houses. It was often utilized to the foundations of castles, fortresses, palaces and different historic 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 also your time and your money. It’s straightforward to install and really effective. The process does not require any additional skills, so you may easily perform it with your own hands.
What’s bentonite waterproofing?
Bentonite pellets are on the core of this insulating material. It is natural material which is capable of polymerization. Sodium bentonite, with its particular structural features, has a tendency to swell rising in quantity 14-sixteen times. Bentonite turns into gel-like substance that fills the cracks and pores of the material of construction. After it gets a strong plastic materials forms, the water-proof insulation layer appears.
To perform bentonite waterproofing in modern building process a number of species of waterproof supplies is normally used. They are divided into four most important categories according to the method of performing:
surface waterproofing which is made usually made of asphalt and cement-based mostly materials;
bentonite waterproofing membrane supplies which are presented by roll-type materials;
polymeric membrane supplies which are roll-mounted,
bentonite mats(or panels).
The main advantages of bentonite waterproofing:
its high impervious properties;
the possibility to make use of these materials in challenging conditions of waterproofing (they’re able to withstand hydrostatic pressure as much as seven levels of atm);
because of its significant improve during hydration in a confined space it has the so-called “self-healing” quality;
the durability of waterproofing materials which is due to its fixed properties over the time;
it could be very simple to perform without requiring any additional skills (compared with traditional technology the hassle in this case is only 20%).
It’s essential to reiterate that the usage of bentonite waterproofing fills even the pores, cracks and voids which are invisible to your eye, achieving an absolute indicator of water resistance – it indeed may give your house something that may be very near the time period “everlasting life”
Nowadays among the most advanced modern materials are bentonite mats. Today they are often used in the construction to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they’re used within the construction of hydraulic constructions and underground buildings of various types and purposes. Bentonite mats are a web-looking materials which consists of two layers of both non-woven and woven geotextile cloth connected in a needle-punched manner. Between them there’s a very powerful part of the waterproofing which is called the natural sodium bentonite (the injection way). It’s layered as a number of moderately thin sheets.
When using bentonite mats specialists identify the following benefits:
the waterproofing work may be performed during any season of the year;
simplicity of the machine;
through 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 within the structure to be remoted;
ability to withstand the unlimited number of freeze/thaw cycles and dehydration/hydration cycles;
effort saving;
time saving;
low water permeability;
almost one hundred% ecological purity;
durability and permanence of properties over the time;
the ability of “self-healing”;
resistance to numerous chemical contaminants;
it can be used 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.
