The sale and distribution of concrete adhesive in Vanak Tehran includes the direct supply of concrete modifier polymer additives (based on latex and epoxy) to increase the adhesion of old to new sections, sealing pools and strengthening repair mortars in construction projects in Region 3. Applicants and construction contractors can receive all types of concrete sealing and standard strength adhesives with the guarantee of real solids percentage, without intermediaries and with daily workshop delivery from the central warehouse of Makzafari tile and ceramic adhesives. This local distribution system reduces the cost of excess transportation and loss of quality caused by long-term depot to zero for the construction workshops of Vanak area.
The dense structure, deep excavations and frequent tower constructions in the axis of Mulla Sadra, Shiraz, Sheikh Bahai and Vanak Square have made the need for high-quality chemical building materials a major priority. The use of non-standard adhesives with a diluted resin percentage is reported to be the main cause of slab tiles, moisture penetration in roof gardens, and failure of concrete joints in this area.
Technical requirements for choosing concrete glue for construction projects
In the field surveys, it has been determined that most of the structures in the Vanak area are facing the risk of permanent moisture in the negative parts of the structure (foundation, negative 3 down and retaining walls) due to their location on the slope and the presence of surface water from upstream. Pouring concrete in these conditions requires additives that cut off the capillary permeability of concrete.
The concrete adhesive used in this area should be modified acrylic copolymers or latex-based synthetic resins. The percentage of solids (Solid Content) in high-quality adhesives should be at least between 35 and 48% to ensure the formation of an elastic polymer film inside the cement matrix. Unfortunately, unbranded samples on the market create false density by adding water or cheap fillers and lack the necessary elasticity against microstructural settlements.
Another use of these additives in Vanak is the installation of heavy facade stones and large size porcelains in office-commercial complexes. The direct combination of sealing concrete adhesive with cement mortar or powder adhesives increases shear adhesion up to three times and prevents materials from falling due to traffic shocks from neighboring highways.
The difference between strength concrete adhesive and sealing in workshop conditions
The experience of implementing reconstruction projects in the older neighborhoods of Venk and Deh Vank shows that not separating the strength concrete adhesive (joint) from the sealing concrete adhesive (waterproof polymer) is the reason for half of the building damages:
- Bonding Agent: The main purpose of this product is to create a mechanical and chemical bridge between the layer of dried concrete and fresh mortar. If you intend to repair the edge of the column or the floor without completely destroying the damaged part, the thick liquid of the strength glue along with the cement powder is applied on the wet surface as a primary slurry (bonding primer) to prevent the separation of the layers. By filling the microscopic voids and better hydration of the cement particles, it improves the compressive and tensile strength and makes the structure resistant to chlorine penetration, soil aggressive ions and freezing cycles. In the construction of roof gardens and swimming pools of residential complexes in region 3, this material is a complete substitute for traditional isogam in the work.

Why is the local purchase of concrete glue in Vanak an economic and operational advantage?
Supplying building materials in the Vanak area is always a serious challenge for the operators due to traffic plan restrictions, the blocking of heavy freight routes during the day and the need for rapid progress of the stiffening and joinery stages. Buying from distant sources such as the outskirts of the city or warehouses in the south of Tehran often leads to delays in concreting, unusual freight costs, and a decrease in the effectiveness of adhesives due to non-standard transportation in cold and heat.
Makzafari tile and ceramic adhesive group has provided immediate delivery of large and small orders for projects in Vanak, Gandi, Kurdistan, Brazil and Ararat neighborhoods by establishing a direct distribution and distribution system in Vanak, Tehran. The advantages of this local distribution center for employers and supervising engineers include the following:
