Since ancient times people have widely used bentonite clay for waterproofing their houses. It was usually utilized 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 financial system – not only of your labor, zalaul01 but additionally your time and your money. It’s easy to put in and very effective. The process doesn’t require any additional skills, so you’ll be able to simply perform it with your own hands.
What is bentonite waterproofing?
Bentonite pellets are at the core of this insulating material. It is natural material which is capable of polymerization. Sodium bentonite, with its particular structural options, has a tendency to swell rising in quantity 14-16 times. Bentonite turns into gel-like substance that fills the cracks and pores of the fabric of construction. After it gets a stable plastic materials 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 are divided into 4 predominant classes according to the method of performing:
surface waterproofing which is made normally made of asphalt and cement-based mostly supplies;
bentonite waterproofing membrane materials which are offered 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 use these supplies in difficult conditions of waterproofing (they’re able to withstand hydrostatic pressure up to 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 materials which is due to its fixed properties over the time;
it is very easy to perform without requiring any additional skills (compared with traditional technology the trouble in this case is only 20%).
It is essential 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 may give your house something that may be very close to the time period «eternal life»
Nowadays among the many most advanced modern materials are bentonite mats. Immediately they are usually used within the construction to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they’re used in the building of hydraulic buildings and underground buildings of various types and purposes. Bentonite mats are a web-looking material which consists of two layers of each non-woven and woven geotextile material connected in a needle-punched manner. Between them there may be a very powerful element of the waterproofing which is called the natural sodium bentonite (the injection way). It is layered as a number of moderately thin sheets.
When utilizing bentonite mats consultants determine the following benefits:
the waterproofing work will be performed throughout any season of the year;
simplicity of the system;
throughout the work it can repair itself eliminating minor mechanical damage arising during set up and backfilling of the pit, as well as a wide range 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 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 used in advanced 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.
