Benefits of bentonite cord

Bentonite cord HYDROSTOP SANPOL is one of the most common and frequently used materials for waterproofing working and cold joints, joints, junctions, places of entry of engineering communications in concrete and reinforced concrete structures.

What is a bentonite cord

Bentonite cord consists of 75% bentonite clay, which, when in contact with water, tends to swell and increase in volume, thus filling voids and reliably sealing the concrete structure.

Due to its unique properties, bentonite cord is today the undisputed leader among materials for sealing joints and sealing leak prevention. It is used for waterproofing vertical and horizontal joints in the construction of basements, swimming pools, wells, sewage systems, and in any structures in contact with groundwater.

The main advantages of bentonite cord:

easy installation
does not require related materials and special tools
possibility of installation at any time of the year, temperature range from 25°C to -15°C
flexibility and plasticity (plasticine–like consistency) - can be used when sealing not clear contours
withstands hydrostatic pressure up to 7 atmospheres
installation on a wet base is allowed
low cost

Bentonite cord is used for:

sealing of cold concreting joints
waterproofing of floor-wall joints
sealing of working seams
waterproofing of joints interrupting concreting
sealing of the places of entry of engineering communications, etc.

Installation of bentonite cord:

First of all, it is necessary to clean the place where the bentonite cord is laid from stones and other construction debris. Fastening can be carried out mechanically on dowels, with the help of a prosechno-exhaust mesh, or on a sealant adhesive. It is necessary to connect the cord according to the tongue-and-groove principle by cutting both ends of the cord in two.

Types of bentonite cord

Depending on the field of application, bentonite cord can be of various shapes and cross-sections:
