Since ancient times people have widely used bentonite clay for waterproofing their houses. It was usually applied to the foundations of castles, fortresses, palaces and different ancient buildings. Over time researches and development of bentonite clays have put them to the highest level. Nowadays bentonite waterproofing is a assure 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's straightforward to install and very effective. The process doesn't require any additional skills, so you may easily perform it with your own hands.

What is 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 special structural features, has a tendency to swell increasing in volume 14-16 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-resistant insulation layer appears.

To perform bentonite waterproofing in modern construction process a number of species of waterproof supplies is usually used. They're divided into four predominant categories according to the tactic of performing:

surface waterproofing which is made usually made of asphalt and cement-primarily based materials;

bentonite waterproofing membrane supplies which are introduced by roll-type supplies;

polymeric membrane materials which are roll-mounted,

bentonite mats(or panels).

The primary advantages of bentonite waterproofing:

its high impervious properties;

the possibility to make use of these materials in difficult conditions of waterproofing (they're able to withstand hydrostatic pressure up to seven levels of atm);

because of its significant enhance throughout hydration in a confined house it has the so-called "self-healing" quality;

the durability of waterproofing materials which is because of its constant properties over the time;

it may be very straightforward to perform without requiring any additional skills (compared with traditional technology the hassle in this case is only 20%).

It's necessary to reiterate that the use 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 provide your house something that is very near the time period "everlasting life"

Nowadays among the many most advanced modern supplies are bentonite mats. As we speak they're usually used within the construction to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they are used within the building of hydraulic buildings and underground buildings of various types and purposes. Bentonite mats are a web-looking material which consists of 2 layers of each non-woven and woven geotextile fabric linked in a needle-punched manner. Between them there is the most important element of the waterproofing which is called the natural sodium bentonite (the injection way). It's layered as a number of quite thin sheets.

When utilizing bentonite mats specialists determine the next benefits:

the waterproofing work can be performed during any season of the yr;

simplicity of the gadget;

in the course of the work it can repair itself eliminating minor mechanical damage arising throughout installation and backfilling of the pit, as well as a wide range of cracks in the construction to be remoted;

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 various chemical contaminants;

it can be used in complicated hydrogeological conditions;

it can withstand hydrostatic pressure of as much as seven levels of atm;

resistance to aggressive environments;

it has a high adaptability, ease of set up in all climate conditions.
