Bentonite waterproofing and its advantages

Bentonite waterproofing and its advantages

Since historic times folks have widely used bentonite clay for waterproofing their houses. It was normally utilized to the foundations of castles, fortresses, palaces and other ancient 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 put in and really effective. The process does not require any additional skills, so you’ll be able to easily 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 particular structural features, tends to swell growing 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 waterproof insulation layer appears.

To perform bentonite waterproofing in modern construction process a number of species of waterproof supplies is often used. They are divided into 4 foremost categories according to the tactic of performing:

surface waterproofing which is made normally made of asphalt and cement-based materials;
bentonite waterproofing membrane materials which are introduced by roll-type materials;
polymeric membrane supplies 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 up to seven levels of atm);
because of its significant increase throughout hydration in a confined house it has the so-called “self-healing” quality;
the durability of waterproofing supplies which is because of its constant properties over the time;
it could be very easy to perform without requiring any additional skills (compared with traditional technology the effort in this case is only 20%).
It’s essential to reiterate that the usage 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 may be very close to the term “everlasting life”

Nowadays among the many most advanced modern materials are bentonite mats. Right this moment they’re often used within the construction to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they’re used in the development of hydraulic constructions and underground buildings of varied types and purposes. Bentonite mats are a web-looking material which consists of two layers of both non-woven and woven geotextile cloth connected in a needle-punched manner. Between them there may be crucial element of the waterproofing which is called the natural sodium bentonite (the injection way). It is layered as a number of reasonably thin sheets.

When utilizing bentonite mats experts identify the following benefits:

the waterproofing work may be performed throughout any season of the 12 months;
simplicity of the gadget;
through the work it can repair itself eliminating minor mechanical damage arising during installation and backfilling of the pit, as well as a variety 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;
nearly 100% 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 complex 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 set up in all climate conditions.
