Select crack and joint materials after establishing the cause, movement and moisture. Filling, flexible sealing and force-transmitting bonding are different tasks. The category includes principal materials and accessories for specific systems.
Assess the defect first
Establish width, depth, activity, water pressure and structural role. An active crack is not resolved by arbitrary rigid filling. For a structural problem, follow the design solution.
Injection materials with different objectives
MC-Injekt PowerSeal R and 2300 flow have flexible sealing applications. MC-Injekt 1264 compact is intended for force-transmitting injection and impregnation of cracks and limited voids. The term epoxy resin does not make it a flooring system.
Primers, packers and compatibility
Mycoflex 251 and 4100 TS are system primers. The PA10110DUO packer is an injection accessory. Select these products with the principal material and equipment; they do not independently perform the function of a sealant.

Frequently asked questions: concrete crack and joint filling
How is a crack treatment material selected?
By cause, movement, width, depth and water. Then establish whether the objective is sealing, filling or force-transmitting bonding.
Can a moving joint be filled rigidly?
Do not assume so without a design solution. Expected movement determines material type and sealing geometry.
What is MC-Injekt 1264 compact used for?
For force-transmitting injection and impregnation of cracks, joints and limited voids according to its data sheet. It is not a general epoxy floor coating.
What is checked when water is flowing?
Flow, pressure, access and material suitability for the conditions. Stopping a leak and permanent filling may require different steps.
Does the primer fill the joint?
No. The primer prepares adhesion in a specified system. The principal sealing is carried out with the designated material.
Does one packer work with every injection setup?
Check size, installation, permitted pressure and equipment connection according to the documentation. Do not assume universal compatibility.
How are quantity and cost calculated?
From area, preparation, consumption of the specific layers and details. Compare the same scope of materials and installation.
Can products from different brands be combined?
Only with established compatibility for the particular system solution. Sharing a category does not establish that arbitrary materials work together.
