Bentonite waterproofing and its advantages

Since historical times folks have widely used bentonite clay for waterproofing their houses. It was often utilized to the foundations of castles, fortresses, palaces and other historic buildings. Over time researches and development of bentonite clays have put them to the highest level. Nowadays bentonite liner waterproofing is a guarantee of functional durability of your house. Moreover, bentonite waterproofing is the real economic system – not only of your labor, but additionally your time and your money. It is easy to put in and really effective. The process doesn’t require any additional skills, so you may simply perform it with your own hands.

What is bentonite waterproofing?

Bentonite pellets are at the core of this insulating material. It is natural materials which is capable of polymerization. Sodium bentonite, with its special structural options, tends to swell increasing 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 stable plastic material forms, the water resistant insulation layer appears.

To perform bentonite waterproofing in modern construction process a number of species of waterproof materials is often used. They’re divided into four fundamental categories according to the tactic of performing:

surface waterproofing which is made often made of asphalt and cement-primarily based supplies;

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

polymeric membrane materials which are roll-mounted,

bentonite mats(or panels).

The primary advantages of bentonite waterproofing:

its high impervious properties;

the possibility to use these supplies in difficult conditions of waterproofing (they are 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 may be very easy to perform without requiring any additional skills (compared with traditional technology the effort in this case is only 20%).

It’s necessary to reiterate that the use of bentonite waterproofing fills even the pores, cracks and voids that are invisible to your eye, achieving an absolute indicator of water resistance – it indeed can give your house something that could be very close to the term «everlasting life»

Nowadays among the many most advanced modern supplies are bentonite mats. Right now they are usually used in the building to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they are used within the building of hydraulic constructions and underground buildings of varied types and purposes. Bentonite mats are a web-looking materials which consists of 2 layers of each non-woven and woven geotextile cloth related in a needle-punched manner. Between them there is an important part of the waterproofing which is called the natural sodium bentonite (the injection way). It’s layered as a number of reasonably thin sheets.

When utilizing bentonite mats specialists identify the next benefits:

the waterproofing work might be performed throughout any season of the yr;

simplicity of the system;

throughout the work it can repair itself eliminating minor mechanical damage arising throughout set up and backfilling of the pit, as well as a variety of cracks within the construction 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 one hundred% ecological purity;

durability and permanence of properties over the time;

the ability of «self-healing»;

resistance to various 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.
