Since historic occasions people 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 assure of functional durability of your house. Moreover, bentonite waterproofing is the real financial system – not only of your labor, but in addition your time and your money. It’s simple to install and really effective. The process doesn’t require any additional skills, so you’ll be able to easily perform it with your own hands.
What is bentonite waterproofing?
Bentonite pellets are on the core of this insulating material. It’s natural material which is capable of polymerization. Sodium bentonite, with its special structural features, tends to swell rising in volume 14-sixteen times. Bentonite turns into gel-like substance that fills the cracks and pores of the material of construction. After it gets a stable plastic materials forms, the water resistant insulation layer appears.
To perform bentonite waterproofing in modern development process a number of species of waterproof supplies is usually used. They’re divided into 4 foremost classes according to the strategy of performing:
surface waterproofing which is made often made of asphalt and cement-based mostly supplies;
bentonite waterproofing membrane supplies which are presented by roll-type supplies;
polymeric membrane materials which are roll-mounted,
bentonite mats(or panels).
The principle advantages of bentonite waterproofing:
its high impervious properties;
the possibility to use these supplies in challenging conditions of waterproofing (they are able to withstand hydrostatic pressure as much as seven levels of atm);
because of its significant improve throughout hydration in a confined space it has the so-called «self-healing» quality;
the durability of waterproofing supplies 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 trouble in this case is only 20%).
It is necessary to reiterate that the use of bentonite waterproofing fills even the pores, zalaul01 cracks and voids which might be invisible to your eye, achieving an absolute indicator of water resistance – it certainly can provide your house something that could be very near the term «eternal life»
Nowadays among the many most advanced modern supplies 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 within the development of hydraulic constructions and underground buildings of various types and purposes. Bentonite mats are a web-looking material which consists of two layers of both non-woven and woven geotextile fabric linked in a needle-punched manner. Between them there may be an important part of the waterproofing which is called the natural sodium bentonite (the injection way). It is layered as a number of relatively thin sheets.
When utilizing bentonite mats experts identify the following benefits:
the waterproofing work will be performed throughout any season of the year;
simplicity of the device;
in the course of the work it can repair itself eliminating minor mechanical damage arising during set up 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 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 as much as seven levels of atm;
resistance to aggressive environments;
it has a high adaptability, ease of installation in all climate conditions.
