Since ancient instances folks have widely used bentonite clay for waterproofing their houses. It was normally utilized to the foundations of castles, fortresses, palaces and other historical 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 is straightforward to install and very effective. The process doesn’t require any additional skills, so you can simply perform it with your own hands.
What’s bentonite waterproofing?
Bentonite pellets are on 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 quantity 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 materials forms, the water-proof insulation layer appears.
To perform bentonite waterproofing in modern building process a number of species of waterproof supplies is often used. They are divided into 4 major categories according to the method 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 make use of these supplies in challenging conditions of waterproofing (they’re able to withstand hydrostatic pressure up to 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 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 indeed can provide your house something that could be very near the term “eternal life”
Nowadays among the most advanced modern materials are bentonite mats. Immediately they’re typically used within the development to perform the vertical and horizontal waterproofing of foundations of buildings. Moreover, they are used within the development of hydraulic buildings and underground buildings of assorted types and purposes. Bentonite mats are a web-looking material which consists of 2 layers of each non-woven and woven geotextile material connected in a needle-punched manner. Between them there’s a very powerful part of the waterproofing which is called the natural sodium bentonite (the injection way). It’s layered as a number of rather thin sheets.
When utilizing bentonite mats specialists identify the following benefits:
the waterproofing work could be performed during any season of the year;
simplicity of the gadget;
during the work it can repair itself eliminating minor mechanical damage arising throughout installation and backfilling of the pit, as well as quite a lot 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 one 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 as much as seven levels of atm;
resistance to aggressive environments;
it has a high adaptability, ease of set up in all weather conditions.
