Admin September 19, 2026

There are various types of crack repair agents for prefabricated house slabs, and you can choose the appropriate repair product according to the crack situation and needs. Here are several common crack repair agents for prefabricated house slabs and their relevant information:

Concrete Crack Repair Agent
This type of repair agent has a wide range of applications and can be used for grout repair of cement floors, filling of PC prefabricated components on road surfaces and floor slabs, etc. For example, the concrete crack repair agent produced by Linyi Huanxing Building Materials Co., Ltd. is priced at ¥329.0. It can penetrate into the interior of the crack, fill and solidify, restoring the overall integrity and strength of the structure. It is suitable for situations where the crack width is relatively large and deep repair is required.

Concrete Crack Sealing and Repair Agent
Taking the Wusheng Zhizao brand as an example, its concrete crack sealing and repair agent has characteristics such as good sealing, waterproofing, and reinforcement effects, as well as high strength. The material is epoxy resin with a specification of 3:1. This repair agent is suitable for sealing and repairing concrete cracks as well as sealing, waterproofing, and reinforcing floor slab cracks. The price varies according to the minimum order quantity. The price for a minimum order of 20 kilograms is ¥21.00, for 400 kilograms is ¥20.00, and for 1000 kilograms is ¥19.00. For surface cracks on prefabricated house slabs that require waterproofing and reinforcement, this type of repair agent is a good choice.

Two-Component Crack Repair Agent
This is an inorganic solvent material composed of various raw materials such as sodium silicate solution and zinc chloride solution. It has advantages such as non-toxicity, environmental friendliness, high bonding strength, and strong weather resistance. It is suitable for crack repair in bridge and highway projects and can also be used for crack repair in prefabricated house slabs. Its two-component design allows it to be mixed in proportion according to needs during use, better adapting to the repair requirements of cracks of different widths and depths. It can provide long-lasting repair effects and enhance the structural stability of the prefabricated slabs.
